The Renewable Heat Incentive

Bookmark and Share

The Renewable Heat Incentive (RHI) scheme is a government initiative similar to the feed in tariff (FIT) scheme and is designed to encourage more people to use renewable energy (solar hot water, air source heat pumps, ground source heat pumps and biomass).

The scheme was announced in March 2011 for payments to those with renewable heat installations including solar thermal.

The scheme is set to start in October 2012 for domestic properties and is currently running commercial installations. However there is a £300 grant available right now up until March 2012 of £300 for people who install solar thermal before that date. This is called the Renewable Heat Premium Payment (RHPP) and if approved you are eligible to apply for the RHI payments once they start.

The government has around £15 million to pay out in Renewable Heat Premium Payments, and once this is gone the RHPP will close so if you are thinking of installing a solar thermal system it is worth applying now. One of advisers can help you with this.

Insulation - Minimum Energy Efficiency Criteria

As with any renewable energy technology, in order to maximise the benefits and returns you should always aim to make your building energy efficient with insulation, use low energy light bulbs and monitor your energy usage and implement a good energy usage regime. Our energy consultants can help advise on ways to be more energy efficient. Since the deemed level of output used to calculate RHI payments will be worked out on the assumption that the building meets a minimum level of energy efficiency, meeting this minimum level is one of the criteria for eligibility.

For domestic houses, the minimum requirements (as set out in the consultation document) are:

  • at least 125mm of loft insulation.
  • cavity wall filled where appropriate.

Some people say that this is too lenient and there is an expectation that this will be one of the areas that is changed before the renewable scheme goes live.

Tariffs For Commercial Renewable Installations

The first phase also includes 20 year tariff support for non-domestic renewable energy installs, aimed at the big heat users - the industrial, business and public sector - which contribute 38% of the UK's carbon emissions.

A generation renewable tariff will be paid for every kWh (kilowatt-hour of energy produced). The level of payment depends on the technology and the system size.

As with the Feed-In Tariff for Solar PV, the tariffs are inflation linked and go up with RPI.

All these renewable tariffs are fixed for a duration of 20 years.
