UK Financial Incentives - Feed-in-Tariffs

The UK Government is committed to increasing the use of low-carbon technologies and provides financial incentives in the form of Feed-in-Tariffs (FITs) for solar PV, Renewable Heat Initiatives and other types of renewable projects as well Green Deal incentives.

The UK Government is legally committed to meeting 15% of the UK energy demand from renewable power sources by 2020, which will help secure the UK’s energy supply and achieve its carbon reduction objectives. Renewable technologies therefore have a crucial role to play in the UK’s energy mix and help to make the most of the UK’s natural resources including solar, wind, thermal and tidal power. UK Government initiatives include:

  • Renewables Obligation (RO): provides incentives for large-scale renewable electricity generation by making UK suppliers source a proportion of their electricity from eligible renewable sources.
  • Feed-in Tariffs (FITs) scheme: pays energy users who invest in small-scale, low-carbon electricity generation systems for the electricity they generate and use, and for unused electricity they export back to the grid.
  • Renewable Heat Incentive (RHI): pays commercial, industrial, public, not-for-profit and community generators of renewable heat for a 20-year period.
  • Renewable Heat Premium Payment (RHPP): gives one-off payments to householders, communities and social housing landlords to help them buy renewable heating technologies like solar thermal panels, heat pumps and biomass boilers.
  • UK Renewable Energy Roadmap: sets out a plan for accelerating the use of onshore wind, offshore wind, marine energy, solar PV, biomass electricity and heat, ground source and air source heat pumps, and renewable transport.
  • Renewable Transport Fuel Obligation: makes companies that supply more than 450,000 litres of fuel per year source a percentage from renewable sources support for other renewable technologies, eg heat networks.
  • ‘Connect and manage network access regime’and other actions to make sure new generators can connect to the electricity network in a timely, secure and cost-effective way.

The Electricity Market Reform proposals also provides support for renewable electricity generation from 2014 onwards. The following tables provide information on the available incentives and tariffs.
