How this is measured

A two-year step, then a slow fall

Substations took 14 in every 10,000 applications in 2021 and 28 in 2023, almost double in two years. The substation planning index peaked at 231 in the 12 months to August 2024. By September 2026 it was 197, almost double the 2016 share.

Highest in the North East

From 2023 to 2025 the North East received 51 substation applications in every 10,000, Yorkshire and Humber 38 and the North West 35, against 25 across the UK. London was lowest, on 15. Leeds leads all councils, with 166 since 2016.

Q3 2026 against a year earlier

Councils received 247 substation applications in Q3 2026: 24 in every 10,000 applications, against 26 in Q3 2025, a share of all applications 8% lower than a year earlier.

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

In England, licensed electricity companies can build substations on their own operational land without planning permission, so these figures lean towards substations proposed as part of another development.
