Early stage: no application yet

Developers often ask the council whether a large scheme needs an environmental assessment before they apply. These requests show what's coming. They are not applications, and they don't count towards the totals above.

By county

How we count

We read the number of homes from each application's description and count each scheme once: under its outline or full application, not again for each later phase, amendment or condition. A scheme that crosses a council boundary is counted once and listed under both councils. "Up to" figures are the most the permission would allow.

"In play" means waiting for a decision (for up to five years), approved in the last three years, or still receiving applications for its phases.

Solar farms, reservoirs, roads and other projects decided nationally are on the national infrastructure projects page.
