FIT: Feed In Tarriff Payments



About Feed-In Tariffs 

Feed-In Tariffs were introduced on 1 April 2010 and replaced UK government grants as the main financial incentive to encourage uptake of renewable electricity-generating technologies. Most domestic technologies qualify for the scheme, including:

  • solar electricity (PV) (roof mounted or stand alone)
  • wind turbines (building mounted or free standing)
  • hydroelectricity
  • anaerobic digesters
  • micro combined heat and power (CHP). 
  • The UK Government's Department for Energy and Climate Change (DECC) makes the key decisions on FITs in terms of government policy. The energy regulator Ofgem administers the scheme.

For you to qualify for FITs, the installer and the products you use must both be certified under the Microgeneration Certification Scheme (MCS), except hydro and anaerobic digestion which have to go through the ROO-FIT process. The tariffs you receive depend on both the eligibility date and, for solar PV, your property’s Energy Performance Certificate (EPC) rating.

Eligibility dates 

The eligibility date is the date from which an installation becomes eligible for FITs payments. For most renewable electricity systems (with a declared net capacity of 50kW or less), this will be the date your FIT supplier receives a valid application for FITs. This will be after the date on which your renewable electricity system is installed, so it's essential to send your application to your FIT supplier promptly – for absolute certainty, use Royal Mail's Special Delivery.

We recommend that you contact your FIT supplier (also known as the FIT licensee) as soon as possible to confirm the requirements below and make sure you know exactly what information they require from you and when they need to receive it by. Please note that you will only be paid for what you generate based on the meter reading on the eligibility date. This is likely to be a later date than when the system was commissioned so units generated before the eligibility date may not be paid. You should check this with your FIT licensee before system is commissioned.

Dates when you add solar panels

The rules are slightly different for an extension. If you add solar panels to an existing system, the eligibility date for the new panels is always the date they were commissioned, not the date that you send your revised claim in. This is particularly important if you want to claim the higher rate by submitting an EPC. The EPC must be dated before the commissioning date or you will not get the higher rate.
If you are eligible to receive FITs you will benefit in three ways:

  • Generation tariff: your energy supplier will pay you a set rate for each unit (or kWh) of electricity you generate. Once your system has been registered, the tariff levels are guaranteed for the period of the tariff (up to 20 years) and are index-linked. 

  • Export tariff: you will get a further 4.64p/kWh from your energy supplier for each unit you export back to the electricity grid, so you can sell any electricity you generate but don't use yourself. This rate is the same for all technologies. At some stage smart meters will be installed to measure what you export, but until then it is estimated as being 50% of the electricity you generate (only systems above 30kWp need to have an export meter fitted, and a domestic system is unlikely to be that big).

  • Energy bill savings: you will be making savings on your electricity bills because generating electricity to power your appliances means you don’t have to buy as much electricity from your energy supplier. The amount you save will vary depending how much of the electricity you use on site.

Tariff rates

Once you are receiving Feed-In Tariffs, the rate you get will increase in line with inflation in accordance with the Retail Price Index (RPI). The tables below summarise the latest tariffs available for each technology. For the full list of tariff rates visit the Ofgem web site.
