FAQ
Are RHI payments taxable?

The Government's Renewable Heat Incentive (RHI) scheme is run across the UK as a way of trying to get more people to switch to using renewable energy. Currently, there are two types of schemes offered: domestic RHI and non-domestic RHI. The first is for personal use and applies to homeowners and families. The second relates to commercial usage and properties.

Both schemes provide grants in return for switching to renewable energy. But the two schemes have separate tariffs and payments, conditions and processes. The tax paid is unaffected by which RHI scheme used to make the payment; instead, the focus is on the way heat is used. For example, commercial use will see you pay VAT, but for personal use, you won't have to.

Ofgem is responsible for administering and implementing the scheme on behalf of the Department of Energy and Climate Change, with the objective of increasing the number of businesses switching to getting heat generated from renewable sources.

At the moment, the heat industry is dominated by fossil fuel technologies which government experts predict will be dangerous in the long term. On top of this, Britain has to meet targets set by the EU to reduce carbon emissions and improve energy security as well as sourcing 'green jobs'.

But who is eligible for the grants and what do businesses or individuals need to do to apply? Non-domestic RHI is for use by commercial, industrial, not-for-profit organisations with installations that are eligible and the public sector. Installations in this context translate as renewable heat units supplying industrial heating on a large scale to small scale community heating projects, such as schools, hospitals and SMEs, or schemes involving district heating (multiple homes served by a single boiler). Every application is subject to the scheme's detailed rules.

Ofgem are responsible for publishing quarterly tariff tables showing the tariffs that will be applicable for each tariff period.

For commercial businesses and outlets, switching to biomass boilers can see huge savings in terms of energy costs - as well as getting a government RHI grant. There are many different types of boilers available for both schemes. For example, the installation and utilisation of straw boilers offers not only ecological benefits but also significant economic advantages. According to construction projects for boiler rooms using our straw boilers and users’ opinions, return on investment expenditure is usually achieved within 2 and 5 years.

Woodchip boilers offer similar returns, according to research. They are ideally suited to high heat load, large-scale commercial installations, such as nursing homes, hospitals, schools and glasshouses. As wood fuel costs so little, those with access to woodland areas have the opportunity to significantly bring down fuel costs by making the entire cycle in-house.

Pellet boilers are another perfect replacement for an oil boiler, as it is fully automated, highly efficient and can reach a high heat load.

What does RHI mean?

The government has a renewable heat incentive scheme (RHI), which is available on domestic properties. It means you could be receiving cash payments over a seven year period, if you install or already have installed certain renewable heating technology such as pellet boilers, biomass boilers and more. To give you a full idea of what RHI is and how it could affect you, we've laid out some of the key aspects of the scheme.

About RHI

RHI is a government scheme which uses grants to encourage homeowners to use renewable heat technologies. It's also available through communities and businesses. The scheme, which is the first of its kind, is being championed by the government with the aim being that 12% of household heating will come from renewable sources by 2020.

It was initially launched in 2014 and provides support through grants to an owner of a renewable heating system over a seven year period. If you live in England, Wales or Scotland you could be eligible for the scheme. It's administered by the energy regulator OFGEM under the department for business, energy and industrial strategy.

How much could you earn using the scheme?

RHI payments are made quarterly over a seven year period. The exact amount you'll receive from the scheme will depend on a wide range of factors, such as the type of technology you install. If, for example you install woodchip boilers, the amount you receive may differ from a homeowner who has straw boilers installed. OFGEM publish the tariffs for different types of boilers, so if you're curious about a particular type of renewable energy, the list is worth studying.

What technologies are eligible for RHI support?

There are a number of different technologies which qualify for support under the scheme, including biomass technologies such as biomass boilers. Ground and air to water heat pumps also qualify, as do pellet based systems like biomass pellet stoves. Solar thermal panels that provide hot water to your home could also see you receive quarterly payments. Burners that produce heat from substances such as agro pellets and wood pellets are also listed as being eligible, but it's always worth checking before installing in case any of the guidelines have changed. It's especially worth consulting a professional if you're about to enter into a long-term contract with a supplier.

Can you apply for RHI?

If you're thinking about installing a new boiler and want to take advantage of RHI, then you should be able to apply as long as you have the right type of technology installed. At the moment, the scheme is open to anyone who is an owner-occupier of a property. If you're a self builder or a private landlord, you can also expect to be able to receive RHI payments. Those who are registered providers of social housing can also make an application for support providing they have installed technology which is eligible. As of now, RHI support is not being made available for new build properties, unless it's a self-build project.

Ultimately, RHI is about encouraging as many people as possible to make the move towards renewable energy. So, if you're thinking of installing a RHI friendly boiler, then don't hesitate to get in touch to see how we can help.

What is RHI?

RHI stands for Renewable Heat Incentive, and it is an incentive scheme that the British government offers to both the domestic https://www.gov.uk/domestic-renewable-heat-incentive and the non-domestic https://www.gov.uk/non-domestic-renewable-heat-incentive marketplaces.

You can find out more about RHI grants by visiting the OFGEM (Office of Gas and Electricity Markets) by visiting their website https://www.ofgem.gov.uk/about-us

The rising popularity of Biomass boilers

Biomass boilers are becoming more and more popular. What's more, they fit into the OFGEM RHI grant scheme. They are environmentally friendly, and this can provide a great benefit to industry, which is by far the largest culprit in the world when it comes to things like emissions and global warming.

The fuels that biomass boilers consume include: • Straw • Wood pellets • Wood chips

The boilers themselves come in a variety of sizes and powers and are suitable for use in various applications from domestic households to large, corporate offices, and industrial factories and plants.

Protecting the environment

As the largest polluters on the planet, the industry needs to stand up and be counted when it comes down to helping to protect our planet's environment. By installing biomass boilers to provide heating, businesses can significantly reduce the amounts of toxic emissions that they pump into the atmosphere year after year.

Many biomass boilers now have advanced emission cleaning systems, so whether we are taking pellet boilers, straw boilers, or woodchip boilers, they can actively fight smog pollution.

Reduced heating costs and improved cleanliness

Up until now, one of the cheapest heating fuels has been coal. The good news is that biomass fuels are a viable alternative. Not only are things like wood pellets cost-effective, they are also extremely convenient to use. Waste is kept to a minimum, is environmentally friendly, and is simple to clean.

State-of-the-art technology

Today’s biomass boilers are built using state-of-the-art technology. They are fitted with electronic controls to automatically fire-up with adjustable timers, and burn sessions can be programmed to automatically switch off.

An excellent long-term investment

The circuitry and the engineering is high quality, which guarantees a biomass boiler's life and makes it a great investment. Depending on the model and size of biomass boiler that you choose, your investment will finish paying for itself within two to five years, so they have excellent ROI potential.

Multi-fuel biomass boilers

As well as biomass boilers that burn specific individual fuels like straw, wood chips and wood pellets, you can also install multi-fuel boilers. As well as having all of the inherent advantages of the single fuel biomass boilers, a multi-fuel boiler will burn the lot, including agro pellets.

Incentive to switch to biomass

The fact that OFGEM offer grants to both householders and businesses indicates the desirability of turning to biomass boilers for heating. The renewable heating incentive (RHI) grants themselves are specifically designed to encourage users to switch to renewable heating fuels, and reduce the amount of carbon emissions that both domestic and non-domestic users produce. Now you too can make a contribution to the environment.

Are RHI payments subject to VAT?

The Renewable Heating Incentive (RHI) is a financial incentive promoted by the UK government designed to encourage businesses to make the switch from fossil fuels to renewables. Under the scheme, users are promised rewards by way of income payments as renewable heat is generated.

Renewable fuels that attract the payments include:

• straw • wood pellets • wood chips • biomass • agro pellet On the face of it the scheme is very attractive; reduce your business’ carbon footprint and get paid for doing so. However, despite the promise of money-back rewards, some potential RHI converts are puzzled as to the position on VAT recovery, as HMRC continues to challenge some businesses’ attempts at reclaiming the tax.

RHI and VAT

HMRC usually regards RHI payments as representing a non-business income. This means that RHI repayments should ordinarily fall outside of the scope of attracting VAT. Businesses are therefore not required to account for VAT on any income they derive from any RHI repayments.

However, HMRC has challenged the entitlement of some businesses to reclaim VAT that is incurred on costs that are used to actually generate RHI payments, their argument being that those costs are not actually attributable to ‘taxable business activities’. Of course, if this argument by HMRC was successful, it could mean that a business was unable to recover VAT on any costs that were directly or indirectly related to the purchase, installation, and maintenance of any equipment or technology that was used to generate renewable heat.

Therefore, any business that was considering the purchase of items such as geothermal or solar equipment, heat pumps, biomass boilers etc would be unable to recover the VAT payable on the cost of such investments. The cost of such equipment is often considerable, meaning that a potentially very large sum in terms of VAT is at stake, posing a significant cost to a business.

Lack of guidance

To further confuse matters, HMRC has not yet published any guidelines on the VAT position of the RHI scheme. However, HMRC officers have in the past challenged input tax recoveries directly related to RHI income. In some cases, this has resulted in VAT claims being disallowed.

In the event that HMRC win the argument, there is a risk that those businesses who have previously successfully claimed VAT on RHI installations would then be liable to pay interest and other penalties, in addition to the repayment of any VAT that had previously been reclaimed.

Next steps

There is currently scope to support full input tax recovery on any costs to RHI that have been incurred to date, and businesses should also take steps to protect their financial position in the future.

If your business has already been challenged by HMRC, you should seek urgent advice as a thorough analysis of your own situation might help to show that any historical input tax recovery would remain valid.

In conclusion, any businesses that are intending to set up a new accredited installation for RHI should always seek advice in order to avoid the possibility of a future challenge.

The Renewable Heat Incentive: its journey from idea to implementation

With climate change and the environment at the forefront of everyone's minds, there has never been a more pressing time to focus on saving fuel and resources through intelligent heating solutions.

For both domestic and non-domestic properties, one such energy and cost-saving solution comes in the form of condensing biomass boilers that generate energy from biomass material, like straw, woodchips and agro pellets. Not only are these devices better for the environment than conventional heating systems, but they attract generous financial benefits owing to a renewed government focus on green energy, via the Renewable Heat Initiative (RHI) scheme.

How did the RHI get passed?

The Renewable Heat Initiative began life via the Low Carbon Building Programme (LCBP), which took effect in the UK on 1st April 2006. Administered by the Department for Business, Enterprise and Regulatory Reform (formerly the Department for Trade and Industry), the scheme had two phases initially: Phase 1 - managed by the Energy Saving Trust - focused on providing grants to homeowners and businesses. Phase 2 was overseen by the Building Research Establishment and extended the scheme from 2007 onwards to public sector and charitable organisations.

Following the publication of the Energy Act in 2008, closure of the LCBP came in May 2010 with a view that a stronger renewable energy framework was needed to replace it. The Conservative/Liberal Democrat coalition in power at the time expressed their commitment via the Government Spending Review in October of that year when plans for the Renewable Heat Initiative were first published. However, a fairly lengthy and turbulent consultation process meant that the scheme didn't come into effect until November 2011.

Following extensive public and industry consultation, in July 2013 the UK Government published a further series of policies and legislative actions supporting low carbon energy initiatives, one of which centred on the RHI scheme, finally providing "long-term financial support" for domestic premises and businesses that install innovative heating technologies and make use of renewable fuel.

Initially, domestic condensing biomass boilers fell outside of the scheme's remit as concerns existed as to the emissions of such devices. From this, the Department for Rural Affairs (Defra) undertook additional testing that focused on Polycyclic Aromatic Hydrocarbons - one of the side-products from RHI boilers - and their effect on water quality. PAHs are products of incomplete fuel burning and are categorised as 'priority hazardous substances' under the EU Water Framework Directive. The government's research found that the environmental impact was minimal and so RHI eligibility was extended in April 2014 to condensing biomass boilers that otherwise meet the usual requirements of the scheme.

The passage of the Renewable Heat Initiative has not been without its controversies - critics point to the 6 years that have lapsed between the enactment of the Energy Act 2008 and the roll-out of the RHI to domestic premises in April 2014. What's clear today, however, is that the scheme offers significant financial and environmental benefits to both domestic and commercial customers who want to use biomass as a fuel source for homes or properties across the UK.

How does the RHI work?

The Renewable Heat Incentive (or RHI for short) is a scheme that financially rewards homes or businesses for using renewable energy for their heating requirements. The aim is to help the UK achieve its target of 12% of its heat coming from renewable sources by 2020. Applications for the RHI are dealt with by OFGEM who also issue the quarterly payments for people within the scheme.

How does the RHI work?

The most important thing to know is that there are two schemes to the RHI - domestic RHI and non-domestic RHI. They each have separate tariffs and joining requirements so it is important to apply for the correct scheme.

The domestic RHI scheme is for homeowners who would like to heat their properties with renewable energy and also gain some financial reward for doing so. To be eligible to join the domestic RHI scheme, the key is that the renewable energy heating system only heats one home and you get a domestic Energy Performance Certificate (EPC) open key term pop up. Getting this EPC is vital to joining the scheme as it is proof you are eligible - without one, you will not be allowed. You will also need a Microgeneration Certification Scheme certificate which is issued by the engineer who installs your renewable boiler and heating system to prove it is eligible. Getting the correct boiler fitted is vital in being able to join.

The non-domestic RHI scheme is for businesses or anything classed as being in the non-domestic sector by OFGEM. This includes industrial, commercial, public sector and not-for-profit organisations with eligible renewable energy boiler and heating installations. To clarify, a non-domestic heating installation is a renewable heating boiler that provides heating via renewable energy such as biomass or wood pellet. For the non-domestic scheme, OFGEM are responsible for producing quarterly tables to show the tariff rates that will apply for each period.

After being accepted onto either scheme, depending on which is most suitable for you, OFGEM will send you a quarterly tariff payment for every kilowatt (kWh) hour of renewable energy you produce. These payments will last for seven years and are the financial incentive the scheme is based upon to help more people to use renewable energy. These quarterly payments act like a grant from the government also in terms of going towards the cost of having a new boiler installed for the purposes of renewable energy heating.

In terms of the technology you can use for the RHI, there are biomass boilers you can have installed to enable you to use renewable heating in your property. Other boilers you may consider are pellet boilers that use pellet or agro pellet, straw boilers that use straw, or woodchip boilers that take wood pellet as their fuel. The RHI is a fantastic scheme and the grants available for domestic or non-domestic use make it highly attractive.

RHI grants and where to find tariff rates

If you're considering installing a new heating system in your home, or in commercial premises, you will naturally want to choose something that is cost effective. You may also be driven to considering installing boilers that are environmentally friendly too. What would you say however, if you could meet both of these targets and qualify for OFGEM RHI grants?

What are biomass boilers and why are they eligible for RHI grants?

The answer to all of the above questions is to install a biomass boiler. All biomass boilers use renewable fuels (things like straw, wood chips and wood pellets). It means that they are preferred products when it comes to the environment, and this is why OFGEM (Office of Gas and Electricity Markets) include biomass boilers in the government sponsored RHI (Renewable Heat Incentive) grant system.

RHI grants have been designed to offer financial incentives to commercial and domestic property owners, in order to increase the demand for installing renewable fuel heating systems.

If you are wondering how you can find out the current rate for an OFGEM RHI grant you must first decide whether you are a domestic or a non-domestic user, as separate grants are available for both groups. Not only are there separate tariffs, according to which scheme you apply for, but eligibility conditions, the application process, and the rules and regulations are also different.

Which RHI grant scheme should you apply for?

If you are applying for non-domestic grants to install renewable heating system, the types of premises that qualify are commercial premises, industrial premises, or premises visited by members of the general public. This covers establishments such as big companies, schools and hospitals, plus properties that have single source heating systems that distribute heat to a number of different homes.

Commercial RHI grants

If you are considering installing biomass boilers in commercial premises, you could be given quarterly payments over a period of 20-years, depending on the amount of heat your chosen system generates. RHI commercial grants are available in England, Scotland and Wales, and there is a separate, stand-alone scheme available in Northern Ireland.

Generally speaking, if the renewable heating system is in commercial, public or industrial premises, then you would apply to the Non-Domestic RHI. This covers large and small businesses, hospitals, education establishments, and organisations with district heating schemes where a single heating system serves various premises.

Domestic RHI grants

If you are applying for domestic RHI grants, these are issued in respect of individual properties which have, or can obtain, an EPC (Energy Performance Certificate). Without an EPC it is not possible to get a grant.

Current tariffs for non-domestic RHI grants

The rates for RHI grants depend on the nature of the renewable heat technology -whether for example it is biomass, solar, etc. - and how much heat it generates. Payments are made in after installation is complete. It normally takes no more than 30-days to get a grant, and once your tariff has been agreed, it will be paid quarterly. Actual tariff fates are decided by the Department of Business, Energy and Industrial Strategy.

Current tariffs for domestic RHI grants

Payment for domestic RHI grants follows a similar pattern to those above in non-domestic grants, but they are only payable over a period of seven years, not twenty. Please click here (https://www.ofgem.gov.uk/environmental-programmes/domestic-rhi/contacts-guidance-and-resources/tariffs-and-payments-domestic-rhi/current-future-tariffs) to see which rates apply according to the OFGEM website.

How do non-domestic RHI schemes work?

The Renewable Heat Incentive (RHI) was set up by the UK Government to encourage more householders and businesses to make the switch to renewable heat installations. If you run a business and are considering making the change away from fossil fuels, you might be wondering how the non-domestic RHI scheme works.

What is the non-domestic RHI scheme?

The non-domestic RHI scheme is open to those in the commercial, industrial and public sector, and to non-profit-making organisations. If your business has an eligible installation, you will be entitled to receive fixed quarterly RHI payments for a guaranteed period of 20 years. The payments are fixed for the duration of your installation’s life (i.e. 20 years), but the tariffs are subject to annual alterations in line with the UK Retail Price Index (RPI).

How does the scheme work?

The non-domestic RHI is applicable to installations using the following renewable energy sources:

• biomass • solar thermal • ground and air source heat pumps • biomethane • biogas combustion technologies

The eligible outputs of your installation include:

• space heating • hot water • commercial, agricultural, and industrial processes

The RHI incentive payments are made every quarter for each kilowatt of heat generated. Payments are based on metered readings that must be submitted by the installation’s owner. The eligible metered reading is calculated by multiplying that figure by the relevant tariff level.

Is your business eligible for RHI payments?

There are a number of criteria that you must meet in order to be eligible for the RHI scheme.

You must be the owner of the installation. In the case of joint ownership, you must be able to show that you are authorised to act for the other owners.

Your installation must also be the right type and size of eligible renewable heat technology. Your installation must have been completed and commissioned after 15 July 2009 and must be one of the following:

• biomass • biogas below 200kWth • water and ground source heat pumps • geothermal • solar collector • energy derived from waste

Installations commissioned after 4 December 2013 are also eligible as follows:

• water to air heat pumps • biogas 200wth and over • CHP system using biomass, waste or biogas

Public grants cannot be used to fund any part of the installation, and the plant must have been new at installation.

The installation must use either steam or liquid as the heat delivery system and must provide heat for at least one eligible heat use. The installation must not be used to solely provide heating for single domestic premises either.

The meter that is used with the installation must be the correct type of meter, correctly calibrated, and placed in the correct location. You must have at least one MID Class heat meter. All equipment eligibility criteria must be met and biomass boilers must meet the air quality requirements.

The qualification requirements for RHI eligibility are complicated and you should check with your local government agency at the time of application to ensure that your business installation qualifies.

Non-domestic RHI - How much is it?

The non-domestic RHI (Renewable Heat Incentive) is an incentive scheme from the Department of Energy and Climate Change. The aim of the scheme is to increase the percentage of the heat we generate from renewable fuels, rather than coal and oil. OFGEM is the body responsible for implementing the rules, regulations and posting the tariffs associated with the scheme. There is a big drive to transform the energy sector from a fossil fuel dominated world to one with significant levels of renewable energy. The RHI is there to help us meet the EU targets which state the necessary reductions in carbon emissions as well as to help shape a future of secure energy.

Who is applicable for the non-domestic RHI?

The non-domestic RHI is open to all businesses that are part of the non-domestic sector. Examples include the commercial, industrial, non-profit and public sectors and organisations. The scheme is only applicable with certain installations of biomass and renewable energy boilers and heaters. The scheme defines a non-domestic installation as an installed unit which uses renewable sources of energy to produce heat on a large scale.

For example, small or medium sized businesses, as well as public and private schools, hospitals, district or town heating schemes (where one unit serves several homes), are all eligible for the non-domestic RHI scheme. All installations and applications are subject to the rules of the scheme as outlined by OFGEM. Those with eligible installations receive quarterly payments from the scheme according to how much heat the installation has generated over the qualifying period. Tariffs are published by OFGEM and are paid within 30 days of each period, over 20 years. The tariff you're on depends on the level of technology of your boiler (solar, biomass etc.) and the level of heat generated.

The full list of tariffs can be found here: https://www.ofgem.gov.uk/environmental-programmes/non-domestic-rhi/contacts-guidance-and-resources/tariffs-and-payments-non-domestic-rhi

What can you earn?

You can earn up to 10.44p/kWh with renewable heat sources and most medium-size biomass (wood chip, pellet or straw) boilers can earn you up to 4.79p/kWh when installed and commissioned on or after 1st of July 2017. The more energy your renewable installation or biomass boiler produces, the more money you get paid. You report your usage to OFGEM each quarter to receive the appropriate amount of money based on the energy your installation has produced, and the tier your installation belongs to.

Biomass boilers can use fuels such as wood chip, pellet and straw to produce heat. There are several benefits to the use of biomass boilers, including the reduction of carbon emissions and the continued source of fuel. You can also use solar power, ground source heat pumps, biogas and other renewable energy sources as part of a qualifying RHI installation.

A long-term investment

Commercial biomass boilers are a long-term investment that can give you cheaper energy, cash back from the RHI scheme and help our environment to flourish without the impediment of high levels of greenhouse gasses.

We provide biomass boilers which are compliant with the RHI scheme. Check out our range of straw biomass boilers from METALERG and wood chip and pellet boilers from EKOGREŃ.

How to calculate RHI

The UK Government’s Renewable Heat Incentive (RHI) scheme pays households and businesses a ‘reward’ for converting to using renewable heat sources, rather than fossil fuels.

There are several factors to be taken into consideration when calculating the amount of RHI incentive you may receive.

Category of RHI incentive

There are two categories of RHI. These are dependent on the type of property you own. ‘Non-domestic RHI’ covers instalments in commercial and business premises, and the second category, ‘Domestic RHI’ covers homeowners, landlords, and self-builders.

Type of renewable system

This element of the calculation looks at the different RHI systems that could be used, i.e.:

• ground/water source heat pumps • air source heat pumps • biomass thermal • solar thermal

All these options have different tariffs, which are taken into consideration when calculating the incentive.

Heating requirement of the property

The factor relates to the amount of heat that is required to keep the building warm enough. This value further depends on some of the property’s individual characteristics, for example, whether the roof, walls, and floors are isolated and the type of glazing installed in the property.

In addition, the government usually requires a certificate showing that the property has good insulation as part of the RHI incentive application paperwork.

System running hours

The system running hours are dependent on the size of the heating system concerned. The proportions of the heating system should be relevant to the space to be heated and this will to some extent depend on the length of time the system will need to operate before it reaches the desired temperature. The size of the heating system will also affect its performance and duration. Another important factor is the temperature that is required within the building for it to be deemed warm enough.

Average inflation level

The final factor in calculating RHI incentive payments is the projected average annual rate of inflation for future years.

The RHI calculation also depends on whether the system operated is a standard or multiple system and is further based on the Eligible Heat Output (EHO). The amount can be ‘metered’ or ‘deemed’.

A metered amount can be calculated based on a simple meter reading that shows how much energy has been used by the installation. A deemed amount is calculated in the absence of a meter, using various algorithms that work out how much the system would use under normal circumstances.

Users considering entering the RHI scheme should note that the tariffs are not fixed, but they are adjusted every year, as per the RPI (Retail Price Index). Any change would be implemented beginning from the first payment period following 1 April each year. RHI instalments are paid every three months and tariff values take into consideration the cost of the renewable energy in 20 years’ time.

In order to make an accurate calculation of the RHI payment that you would receive, you should use the appropriate RHI incentive calculator.
