What is a garage conversion?
A garage conversion turns an integral or attached garage into habitable space, such as a study, playroom, bedroom or utility. The garage door is replaced with a wall and window, the floor is raised and insulated, and the walls and roof are brought up to building regulations.
How much does a garage conversion cost in Kempston?
In Kempston, a garage conversion typically costs £19,000–£32,000 for a single integral garage, including VAT at 20% (standard rate). Prices across the East of England are typically 6% above the UK average for this kind of work, which is reflected in the range for Kempston. Design, structural calculations and council fees are extra.

- Whether planning permission is needed
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a garage conversion in Kempston?
Approvals for a garage conversion in Kempston follow the rules for England. In England converting an integral or attached garage usually does not need planning permission, unless a condition on the house removed permitted development rights (common on estates built in recent decades) or the house is listed. Building regulations approval is always needed.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
On a typical garage conversion we handle:
- Floor raised with insulation and damp-proof membrane
- Planning check for removed permitted development rights
- Electrics, heating and plastering
- Foundation check under the garage door opening
- Building control completion
- Wall and ceiling insulation
How long does it take?
Build time is typically 3 to 6 weeks on site. Before that, surveys, drawings and approvals usually take 6 to 12 weeks, longer if the council asks for changes.
