Garage Conversions

As a 2025 UK guide, a garage conversion typically costs between £6,000 and £20,000. The biggest factors are insulation, flooring and damp-proofing, new heating, electrics and glazing, and whether an ensuite or kitchenette is added. These are guide figures only — the best way to get an accurate price is two or three quotes, which our free matching service arranges for you.

Most garage conversion projects take around 3–6 weeks on site, plus design time and any approvals beforehand. Your matched specialist will give you a firm schedule once they've seen the project.

The essentials are insulating the walls, floor and ceiling, damp-proofing, raising and levelling the floor if needed, and extending heating and electrics. Done properly, the room feels no different to the rest of the house — which is why insulation is the job to get right.
