How does the RHI work?
The RHI, or Renewable Heat Incentive, is the Government's Pay As You Generate scheme for domestic renewable heat installations. The RHI will be administered by Ofgem E-Serve and is open for applications from Spring 2014, although the enquiries line is already open (0300 123 1234). More information on the administration of the RHI can be found on the Ofgem E-Serve: Renewable Heat Incentive web pages. The RHPP grant scheme is administered by the Energy Saving Trust. Applications for the RHPP can be processed on line - see the RHPP page for more information.
How the RHI works
The way the Renewable Heat Incentive works is fairly simple. First, the user pays for and installs an eligible renewable heat technology – the scheme covers biomass pellet stoves with a back plate boiler, biomass only boilers, water source heat pumps, ground source heat pumps, air to water heat pumps and evacuated and flat plate solar thermal installations. If the technology and the customer’s circumstances meet the requirements of the RHI scheme (below), they can then register the system with Ofgem who administer the RHI scheme.
They are then eligible to receive the Renewable Heat Incentive payment quarterly for the next 7 years. The amount paid is adjusted upwards for inflation over the payment period and is also dependent on a number of factors including:
- Amount of heat generated
- Technology type
The payment is designed to cover the difference between the installation cost for the renewable heat technology and the installation cost for a conventional system, the running costs of the system and any interest charged by finance providers.
At the end of the 7 years these costs should have been fully reimbursed to the customer. The lifetime of the technology is 20 years, so the customer will get a further 13 years’ worth of energy bill savings with that installation.
Customers applying to the RHI scheme can also apply to the RHPP grant scheme. which gives one-off grants for renewable heat installations. Applying for both has the effect of giving you more of the payable money upfront, as the RHPP grant amount will be deducted from your RHI payments to avoid a double subsidy.
- Solar thermal: At least 19.2p/kWh (Increases to this rate may be confirmed in Autumn)
- Biomass boiler: 12.2p/kWh
- Air to Water Heat Pump: 7.3p/kWh
- Ground Source Heat Pump: 18.8p/kWh
You Qualify for the RHI scheme if:
You installed an eligible technology after the 15th July 2009. Currently the qualifying technologies for domestic installations are:
- Solar Thermal water heating
- biomass boiler
- air source heat pump
- ground source
- water source heat pump
Your installer and installation will also have to be MCS certified – check that your installer is MCS compliant before going ahead with the work.
How to Apply to the RHI
DECC have said that information on how to apply to the RHI scheme will be released shortly – in the meantime, you can direct any questions about the scheme to the Energy Saving Advice Line on 0300 123 1234.
- What is the Renewable Heat Premium Payment?
- The Renewable Heat Premium Payment is a scheme to support people who want to install renewable heat technologies. It will also help the government learn more about how these technologies work in practice, prior to the expansion of the Renewable Heat Incentive to the household sector.
- What are the Renewable Heat Premium Payment eligibility criteria?
- The main criteria are as follows:
- Applicants must be the owners of or reside in the property for which the grant is applied (alternatively applicants who have leasehold ownership or tenancy occupation must have permission from the property freeholder) and it must be their primary residence.
- For heating systems other than solar thermal, this must be the main heating system in the house.
- The installation address must be situated in England, Scotland or Wales (the scheme is not available to addresses in Northern Ireland, the Isle of Man and the Channel Islands) and must be the applicant primary residence or a property occupied for the majority of the year.
- Eligible technologies are Solar Thermal Hot Water, Air to water source Heat Pumps, Ground Source Heat Pumps, water to water heat pumps and biomass fuelled boilers (eg wood or wood pellet). Air to air heat pumps, wood fuelled stoves (unless they are part of a system with a back boiler) and bioliquid fuelled systems are not eligible for this scheme.
- Solar Thermal Hot Water systems will be available to all householders.
- For other technologies applicants must not currently use mains gas supply for their heating system.
- Applicants must use a Microgeneration Certification Scheme (MCS) certificated installer (www.microgenerationcertification.org) and product or equivalent.
- Renewable heating systems must supply a permanent residential building (mobile homes, caravans, house boats and systems heating swimming pools only are not eligible).
- Basic energy efficiency measures must have been installed at the installation address (loft insulation up to 250mm where appropriate, cavity wall insulation where practicable).
- Applicants must have received all relevant permissions for the installation including planning permission where required. If in doubt, please confirm with your local authority whether planning permission is required.
- Will I need to pay for any monitoring that is carried out?
- A significant proportion of applicants will be approached by Energy Saving Trust to have additional meters attached to their installation which will monitor the performance of the heating system. They will not have to pay for these or take readings themselves. Everyone has to agree to let a meter be installed as part of the terms and conditions of the scheme. For everyone else, any meters and controls which come with the product already will be sufficient. You will be asked through surveys information about these meters and the bills that you get; and in particular how easy it is to understand the meters and the controls, as well as general feedback on your satisfaction with the system installation and its performance.
- Can I apply for more than one technology?
- Yes, although you must complete a separate application form for each technology. You cannot apply twice for the same technology at the same installation address.
- How long will it take to receive my Renewable Heat Premium Payment voucher?
- If the information you have given in your application satisfies the eligibility criteria of the scheme then you will usually receive immediate confirmation of whether your application has been successful. If you have been awarded a voucher, this will be emailed to your nominated email address within 24 hours. Occasionally applications will be referred to our administration team for further checking. You will be alerted to this once your application has been submitted and you will receive notification of whether it has been successful within 5 working days.
