What can I build, and will it pay? The planning rules, what neighbours have built, planning decisions, energy upgrades, and whether extending pays.

A home's own recommended upgrades and their costs are on its energy certificate, shown on its page.

Across England and Wales, homes extended by a typical 30 m² and then resold rose about 11.1% more than similar homes nearby over the same years (124,884 resales); in Yorkshire & Humber, 8% (12,484 resales).

| Stamp duty on the new home | £1,320 |

| Estate agent on yours 1.2% + VAT | £2,232 |
| Solicitors, buying and selling | £3,000 |
| Survey | £600 |
| Removals | £1,500 |
| Money gone | £8,652 |
| Building, plus 15% for design, planning and contingency | £57,500 |
|---|---|
| Less what it adds to your home's value 60% of the local price | −£21,600 |
| Money gone | £35,900 |
On these figures, moving loses about £27,248 less. Moving also changes the area, the schools and the commute; extending means months of building work and depends on planning.
Building costs vary a lot (a single-storey rear extension is often £2,000–£3,000 per m², more in London). How much space adds depends on the home and street: what extensions added to resale prices. A guide, not advice; nothing you type leaves this page.

Not every extension shows here. We only see building work when a new energy certificate is lodged, which happens when a home is sold, let or newly built. A loft or extension added since then won't appear, even with planning permission and building control sign-off, because those records aren't published as open data outside London. Missing work doesn't mean missing paperwork.
From energy certificates: an extension where a later certificate shows more floor space, a loft conversion where roof rooms appear.
