Garage & Loft Conversion Electrics
Electrics for garage and loft conversions, covering new circuits, supplies, lighting, heating control and detection, tested and certified on completion.
Conversions turn unheated, lightly wired space into a habitable room, and the electrical requirements change with it. A garage with one strip light and a single socket becomes a bedroom, office or annexe with proper circuits, heating control and detection tied into the rest of the house.
Loft conversions add the complication of routes and access, since cables have to reach the new floor without tearing the ceilings below apart. Planning that early is what keeps the making good manageable.
Typical conversion scope
- New circuits extended from the existing board
- Consumer unit capacity check and upgrade if required
- Sockets and data planned around the intended use
- Lighting, switching and two way arrangements on stairs
- Heating and underfloor heating controls
- Interlinked smoke and heat detection
- Shower room or en suite wiring to zone requirements
- Testing, certification and notification

Frequently asked questions
Does a conversion need a new consumer unit?+
Only if the existing board has no spare capacity or lacks current protection. We test first and tell you.
Will you have to lift ceilings downstairs?+
We plan routes to avoid it where possible. Some access is often needed, and we agree it before starting.
Does detection have to change?+
Conversions commonly require interlinked detection across the house. Building control will confirm what applies to yours.
Is conversion work notifiable?+
New circuits and special locations usually are. We certify through our registration and confirm the position for your address.
