How much does a garage conversion cost in Cardiff?
In Cardiff, a garage conversion typically costs between £5,500–£18,000, depending on the project. Welsh building costs are usually below the UK average — South Glamorgan labour and materials are a real factor. The biggest cost drivers are insulation, flooring and damp-proofing, new heating, electrics and glazing, and whether an ensuite or kitchenette is added. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.
Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.
How long does it take?
A garage conversion in Cardiff usually takes 3–6 weeks, though planning and material lead times can affect the schedule.
- Sort insulation first. Garages are cold — proper insulation is the key to a comfortable room.
- Check the floor level. Garage floors often need raising and damp-proofing.
- Plan heating & electrics. Extend your central heating and add sockets where you’ll need them.
