The Feed-in Tariff

The Feed in Tariff is a government scheme based on a German model, designed to promote and incentivise the installation of renewable energy systems that produce electricity, by paying people for every kilowatt they generate.

Current technologies in the FIT are:


Frequently asked questions

How do I qualify?

isoenergy are MCS accredited for the following technologies: ground source/ air source heat pumps. solar pv, solar thermal, biomass.

The majority of isoenergy's FIT eligible installs are systems below 50kW.

There are two major criteria for these systems to qualify.

  • MCS Certified Equipment - Installed equipment must be certified by the Microgeneration Certification Scheme (MCS).
  • MCS Accredited Installer.

isoenergy is a fully accredited member of the MCS scheme. We ensure that we only install MCS accredited equipment whenever possible. This includes the vast majority, if not all, of our solar PV systems.

isoenergy will, where approporiate, help advise and assist with any extra forms or applications required by the FIT scheme to make your installation run as smoothly as possible.

What is the Solar PV benefit?

Regardless of size of install you can be generating a 9-11% return on investment (ROI) within minutes of the final system commissioning.

By far the easiest and most popular technology in the FIT is Solar PV. Installation is possible in a vast majority of properties, regardless of size and can be generating a 9-11% return on investment (ROI) within minutes of the final system commissioning.

Here is a chart to show what successfully qualified systems will be paid per kilowatt hour, and for how long:

Summary of solar PV tariffs for systems with an eligibility date between 1st April and 30th June 2017.

Band (kW)

Standard generation tariff (p/kWh)

Multi-installation tariff (p/kWh)

Lower tariff(if energy efficiency requirement EPC band D not met) (p/kWh)

 < 10kW 4.04 3.64 0.47
>10-50kW  4.25 3.83 0.47
>50-250kW  1.94 1.75 0.47
>250kW-1MW 1.59 n/a n/a
stand-alone 0.38 n/a n/a

Information taken from Energy Saving Trust figures.

  • The new tariff rate for solar PV
  • The export tariff rate will increase to 4.91p/kWh for all new solar PV installations.
  • The tariff period (lifetime) for solar PV is 20 years for all new installations.
  • The tariffs are to be reviewed every three months and will be revised according to deployment rates

Please note this information is subject to change. Refer to the Ofgem website for further information and updates.

What are the rates for technologies other than Solar PV?

If you install a wind, hydro or microCHP system you can also benefit from the FIT.

For wind, hydro and microCHP installations with a comissioning date on or after 1 December 2012:

  • The UK Government has confirmed there will be NO EPC requirement for non-solar PV technologies
  • The export tariff rate for new installations will go up to 4.5p/kWh

Below is a table of the FIT rates for technologies other than solar PV:
