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 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.
- Can I install the heating system before applying for a Renewable Heat Premium Payment voucher?
- You can, but at your own risk. Installations made from the announcement of full details of the scheme on 21st July 2011, but before the application for the voucher, will be eligible, including installations made between 21st July and 1st August 2011. If you as a householder do commission or carry out an installation before receiving a voucher, please make sure that you have read the terms and conditions of the scheme carefully. The Government or Energy Saving Trust, who administer the scheme, will not be liable for any costs in relation to decisions you have taken on this basis.
- What is the Renewable Heat Incentive (RHI)?
- The RHI will provide payments over a set period of time to generators of renewable heat. It starts in September 2011 for industrial, commercial and public sector installations and Government has announced its intention to make support under the scheme available to households in Autumn 2012.
- Is there any guarantee should my technology not work to expectations?
- If you use an MCS installer and product (or equivalent) for your installation you should receive a warranty for both the equipment and workmanship of your installation. Ask your installer about this; it is always a good idea to seek more than one quotation and you may wish to consider the type of warranty on offer alongside other considerations such as price. We will introduce you to 3 installers to ensure you get a good range of quotes.
- Will I need planning permission for my installation or to notify my Local Authority?
- Most installations are now classed as permitted development which means planning permission is not needed, but this will depend on the technology you are installing and where you live. Please check with your Local Authority before proceeding to ensure you have all of the correct permissions required and see further information on Planning Permission.
