Garage conversion guides
How much does a garage conversion cost?
Cost depends mainly on the garage's existing condition and whether plumbing is needed — here's general guidance to help you budget.
General cost ranges
As general UK market guidance: a basic conversion (insulation, flooring, plastering and electrics only) often runs £6,000–£12,000. A mid-spec conversion including heating, new windows and a higher-quality finish typically runs £12,000–£20,000. A higher-spec conversion including plumbing for an en-suite or kitchenette can run £20,000–£35,000 or more.
These are indicative of the wider UK market and aren't East Yorkshire Renovations' confirmed pricing.
What moves the price
Existing damp and floor level issues can add cost if they need addressing before the conversion can proceed. Plumbing, if included, is usually the next biggest factor, followed by window and door replacement and the interior finish specified.

Frequently asked questions
FAQs.
Is a detached garage conversion more expensive than an integral one?
Often, yes, since a detached garage typically needs its own services run out to it, similar to a garden room, which adds cost compared with an integral garage already close to existing supplies.
