Garden Office & Outbuilding Power
Sub-mains, lighting and sockets for garden offices, gyms and studios.
Working from the bottom of the garden? We run a properly sized sub-main, fit a small consumer unit out there, and wire lighting, sockets and heating.
What's involved
SWA armoured cable buried at depth from the house consumer unit, a small dedicated board at the outbuilding, sockets, lighting and any heating you need.
Why size matters
A garden office with a heater, monitors and a kettle pulls real current. We size the sub-main for the actual load so nothing trips on a Monday morning.
Why us for this
- Correct sub-main sizing
- Small consumer unit at the building
- Buried armoured cable
- Full certification
Common questions
From around £900 for a typical install up to ~20m from the house. Longer runs and bigger loads we quote after a quick survey.
Not for the electrics — but the building itself may. We can advise on the electrical side and you (or your builder) handle the structure.
