How this is measured

Above the 2023 high

Councils received 11,756 solar panel applications in 2023, almost five times the 2,391 of 2020. Counts eased to 10,081 in 2025 while all applications fell. The solar panel planning index stands at 1,029, just above its August 2023 level of 1,013.

Highest in the South West

From 2023 to 2025 the South West received 289 solar panel applications in every 10,000, against 228 across the UK. The East of England followed on 267. Northern Ireland was lowest, on 108. Cornwall has received 1,125 since 2016, more than any other council.

Q3 2026 against a year earlier

Councils received 2,737 solar panel applications in Q3 2026: 266 in every 10,000 applications, against 224 in Q3 2025, a share of all applications 19% higher than a year earlier.

Questions

How many solar panel planning applications are there in the UK?

Councils have received 62,949 since January 2016, 10,481 of them in the 12 months to September 2026. Their share of all applications is the highest since 2016.

Which councils get the most solar panel applications?

Cornwall, North Yorkshire and Dorset have received the most since 2016.

Are solar panel applications rising or falling?

Below the 2023 peak on the count, at its highest on share. Councils received 10,481 in the 12 months to September 2026, against 11,756 in 2023, but the solar panel planning index reached 1,029, the highest since 2016, because total applications have fallen.

Why are there fewer applications than solar installations?

Most domestic rooftop solar in England is permitted development and needs no planning application. Those rights widened on 21 December 2023 to cover flat roofs and remove the 1 megawatt limit on non-domestic rooftop systems.

About Plota

Plota is the UK's most visited planning search, according to Similarweb. It shows every new planning application from every UK council, read daily from 390 planning registers, with past applications back to 2016 from more than 420 registers, including those of councils since merged. It also covers planning committee decisions, HMO licences and premises licences.

How this is measured

What needs an application

Most domestic rooftop solar in England needs no application, and those rights widened in December 2023, so these figures follow schemes that still need permission, not installations.
