Turning a garage into a room or office? We handle the complete electrical fit-out — circuits, sockets, lighting, heating and data — designed and certified for habitable use.
Electrifying a garage: what "habitable room" electrical means
Converting a garage into a bedroom, office, gym, or playroom is one of the highest-ROI home improvements — you're adding genuine living space. But the electrical work is non-negotiable: the new room has to meet the same Building Regulations as any other habitable space, which means proper circuit protection, RCD protection, dedicated heating circuits, and full earthing/bonding. A garage wired with "just a few extra sockets" isn't compliant and will fail inspection (if you ever sell, the surveyor will flag it).
What the electrical includes
New circuits for lighting, power, and heating; plenty of sockets (at least 2–3 double sockets plus USB); data points if it's an office; good insulation on cables since garage conversions are often damp; and often under-floor heating or electric radiators (since garages rarely have heating pipes). If you're planning an ensuite bathroom attached to the conversion, we include the bathroom-specific RCD protection. Air conditioning or a heat pump? We size the circuit for it.
Cost and timeline
Electrical work for a garage conversion typically costs £2,000–3,500 depending on how many circuits, whether heating is included, and cable routing complexity. The electrical rough-in (first fix) happens early when walls are open; second fix happens as the room is finishing. We coordinate with your builder's schedule so there's no delay — electrician slots in during key stages, not when the room is sealed.
Part of a bigger project
A garage conversion usually involves structure (roof/walls), insulation, plastering, and flooring too. We're just one trade, but a critical one — get it right and the conversion is saleable, certified, and future-proof. Get it wrong and you've got a non-compliant room that's risky and unsellable.
Certification and compliance
On completion you'll receive an Electrical Installation Certificate and a Building Regulations completion certificate (coordinated with your local authority). Both matter if you ever sell or refinance the home. Many lenders and buyers specifically ask for these, so they're not optional.
