Solar repairs across England, Wales and southern Scotland

Is your Feed-in Tariff paying what it should?

Three quick questions. We’ll compare what you were paid with what a working system your size should earn on the 2026/27 tariff.

When was your solar installed?

Roughly is fine — the month and year on your FIT statement.

How big is the system?

The kWp figure is on your MCS certificate or FIT statement. Not sure? Count the panels instead.

Which way do the panels mostly face?
What did your FIT payments come to?

Add up the amounts on your statements — generation and export together.

How the check works

The check estimates what a working system of your size, age and direction should generate in a year, then applies Ofgem’s 2026/27 generation tariff for when it was installed, plus export at the deemed 50% rate. If what you were paid is well below that, something may be wrong with the system, the meter or the readings.

Questions people ask

How are feed-in tariff payments worked out?

You’re paid a generation tariff for every unit your generation meter records, at the rate fixed when your system was registered and adjusted each April for inflation. Most homes are also paid for export on an estimate of half of what they generate. See feed-in tariff rates 2026/27.

Why have my FIT payments dropped?

Usually because the system is making less: an inverter fault, a tripped switch, shading or a failed panel. Sometimes it’s a missed or estimated meter reading, or a faulty generation meter. Check the inverter is on and send an up-to-date reading first. See feed-in tariff meter readings.

What should I do if my payments look low?

Check the inverter is on and generating, send a fresh meter reading to your FIT supplier, and compare a year’s readings with what a system your size should make. If it still looks low, we can test the system and the meter, with a clear written quote before any work starts. You can also switch FIT supplier if their service is poor. See switching your feed-in tariff supplier.

Estimate only. Generation tariffs are Ofgem’s FIT rates for 1 April 2026 – 31 March 2027 (higher rate, retrofit), export at the deemed 50% rate. Expected generation assumes a typical unshaded UK roof. Output is a little higher in the south and a little lower in Scotland. Your statements and your own meter readings are the final word — this check is to tell you whether it’s worth looking into.
