Find answers to your questions about renewable energy tariffs and energy options

What if I own more than one installation - will I be paid less?

Not unless you are in receipt of tariffs for more than 25 solar PV installations.  If that is the case, you will receive a lower tariff.  These lower tariffs are in the third column of the table linked here, and described in the footnotes to this table.

Does my property need to have a certain level of energy efficiency to be eligible?

Yes - but for solar PV systems only.  From 1 April 2012, the property to which your solar PV system is electrically connected (or attached) must have an Energy Performance Certificate rating of D or better.

Can I link to your website?

What happens if I start earning the Feed-in Tariffs and then I move house?


A FITs registration is specific to a defined system in a specified location. It would lose eligibility if you dismantle the system and move it elsewhere.

In principle, therefore, when you move house, you have two choices.  The first is to sell the system along with the house to the new occupants, who would then receive the tariffs.  This is the most common option taken.

Alternatively you could in theory retain ownership of the system.  In this case, you could continue to receive the generation and export tariffs, but would have to reach agreement with the new occupants about leaving your system on their roof. As part of this arrangement, you would probably allow them to have the benefit of the free electrical generation.  This is a much less used option as it is difficult to set up legally.

What is Microgeneration?

It is the production of heat or electrical energy at small scale.

This is defined in legislation as follows:

  • Electricity generation at capacities up to 50kW
  • Heat production at capacities up to 45kWth

What is the Microgeneration Certification Scheme (MCS)?

It is a nominally industry-led scheme to provide quality assurance for microgeneration products and installations.

Both the Feed-In Tariffs (for systems below 50kW) and the Renewable Heat Incentive (for systems below 45kWth) require that that the major equipment is product-certified and that the installers is accredited.

For MCS-accredited products see here. For accredited installers see here or, because they also have to be accredited under the REAL code,  here.

What are the Renewable Energy Directive (RED) and Renewable Energy Strategy (RES)?

The RED is the directive adopted by the European Union in 2009 to increase the proportion of renewable energy produced in Europe.

Each country has its target for renewable energy in 2020 averaging 20% across the whole EU.

The UK has signed up to this directive with a national target of 15% of all the UK's energy to come from renewables by 2020. The way this will be achieved is set out in the National Renewable Energy Action Plan (NREAP) and the Renewable Energy Roadmap.

What’s the difference between a co-developer and a normal project developer?

A co-developer is an expert company, which works with a site owner or energy user to realise a renewable energy project. Normal project developers aim to install the project as principal, and may rent the land from the owner and/or provide electricity to local users.

In a co-development the project owner will retain most of the revenues generated from the Feed-In Tariffs. A normal project developer would keep all this benefit, and pay a modest rent to the landowner.

Is it true, local councils are banned from selling electricity?

Yes it was, under the 1976 Local Government Act. However, DECC reversed this law in August 2010.

How easy is it to generate your own power?

Once you have your systems installed it is tremendously easy as your system will do everything automatically for you.

The more challenging bit is knowing what to install and how to do it. That is why we set up Ownergy!
