See how the RHI can pay you back.

The Domestic and Commercial RHI is now in full swing with applicants receiving payments, covering 100% of the installation cost. The reduction in the Biomass tariff has allowed an increase in heat pump payments meaning installing a heat pump has never been so attractive

Environmental & financial benefits

Practical sustainable and renewable energy sources mean reductions in the use of fossil fuels through the use of proven technology.

Reduce your CO2 emissions: on average a heat pump could save around 1.8 tonnes of carbon dioxide every year when replacing an oil boiler.

  • Domestic heading accounts for over 35% of CO2 emissions in the UK.
  • Over 60% of the average homes CO2 emissions are created by the heating and hot water system.
  • Ground & Air source heat pumps are simple to install and are a direct replacement for existing oil and gas fired boilers.
  • Ground & Air source pumps are a proven technology which have been used all over the world as a primary domestic & commercial heat source for over 50 years.
  • Due to the high COP created by ground & air heat pump annual fuel bills can be reduced by as much as 50% when compared against Oil and LPG boilers.
  • With the RHI funding you can have your ground or air source heat pump system paid for within 7 years.
  • With Green Deal assistance a loan is available to pay for the upfront installation cost and when combined with the RHI you could have your system paid for in under 5 years!
  • RHI funding is now available for Commercial air source and ground source heat pump systems.

Domestic RHI (Renewable Heat Incentive) Update March 2016

At South West Energy Services, we provide constant updates of changes to industry funding and regulation. There have been some changes to the RHI for 2016. Below is a summary of the changes from Ofgem.

1. Green Deal Assessments

Currently we require applicants to the domestic RHI to have a Green Deal Assessment (GDA). This is to provide them with information about the efficiency measures that are suitable for their homes. This initially applied to all applicants but Registered Social Landlords (RSLs) were made exempt from this requirement in February 2015.

It was announced in July 2015 that there would be no further funding to the Green Deal Financing Company. This, alongside consistent feedback that a GDA is an unnecessary burden to scheme participants, has resulted in us changing the Regulations by removing the need for a GDA as an eligibility requirement for the Domestic RHI. Applicants will still need to meet minimum insulation requirements of loft and cavity wall insulation and provide a valid Energy Performance Certificate (EPC) that is no more than 24 months old.

2. New Build Properties – 183 Day Occupancy

The domestic RHI requires that if a property is occupied for less than 183 days, in a 12 month period, a heat meter must be installed to measure renewable heat use and determine payments, instead of payments being based on the annual heat demand specified on the property’s EPC.

This occupancy requirement ensures that the Domestic RHI delivers value for money for the taxpayer by not overpaying for renewable heat systems installed in properties that are not continuously occupied (for example, second homes).

This has resulted in the unintended consequence of eligible new self-builder properties having to wait 183 days prior to scheme application or installing heat meters as they are unable to provide evidence that they have lived in their homes for at least 183 days in the previous 12 months.

To overcome this, we are amending the regulations to make eligible new build properties exempt from the 183 day occupancy requirement in the 12 months prior to application to the scheme. Thereafter, these participants will be subject to the standard ongoing obligations which include the annual declaration that the property has been occupied for 183 days or more in the last 12 months.

3. Tariff Indexation

Tariffs in the both the Domestic and the Non-Domestic RHI are subject to an annual adjustment in line with inflation to take into account changing prices in the economy. The indexation rate used to date has been the Retail Prices Index (RPI).

RPI is no longer classified as a National Statistic, therefore, for all applications accredited on or after 1 April 2016 tariff adjustments will be linked to the Consumer Price Index (CPI). CPI is already widely used across Government, for example for the uprating of pensions, wages and benefits. Current scheme participants will continue to have their tariff linked to RPI.

4. Degression Triggers

Spending in the RHI scheme is controlled through the degression mechanism. This operates by applying an automatic reduction to a technology tariff if pre-determined expenditure trigger points are exceeded. Expenditure is assessed every 3 months.

Individual technology trigger points for the scheme are set out in the Regulations. Currently the Regulations only specify triggers up until the 31 January 2016 assessment date; the next assessment against expenditure is due 30 April 2016, which will inform any tariff reductions that take place on 1 July 2016. In these Regulations we updated the expenditure trigger points for the scheme until the 31 January 2017 assessment date.
