Professional Garden Office Wiring

A garden office needs more than an extension lead through the window. Running a dedicated SWA (Steel Wire Armoured) cable supply gives your outbuilding its own independent electrical system — properly earthed, RCD-protected, and capable of running multiple circuits for lighting, heating, computers, and even EV charging.

We handle everything from trenching and cable routing to installing a dedicated consumer unit in your garden office. The result is a safe, certified electrical installation that meets BS 7671 and Building Regulations — essential for insurance purposes and if you ever sell your property.

Frequently Asked Questions

How do you get power to a garden office?

We run a Steel Wire Armoured (SWA) cable underground from your main consumer unit to a new small consumer unit in the garden office. The cable is buried at a minimum 500mm depth (or 600mm under driveways) in accordance with BS 7671. This provides a safe, dedicated supply separate from your house circuits.

How much does it cost to wire a garden office in Devon?

A typical garden office electrical installation costs £1,200-£3,000 depending on the distance from the house, number of circuits, and spec required. A basic setup with lighting, sockets, and a heater circuit sits around £1,200-£1,800. Higher-spec installations with data cabling, multiple circuits, and EV charger prep range £2,000-£3,000.

Do I need planning permission for garden office electrics?

The electrical installation itself doesn't require planning permission, but it is notifiable under Part P of the Building Regulations. As qualified electricians, we self-certify all work and issue the required certificates. Your garden office building may need planning consent depending on size and position — we can advise.

Can you install heating in a garden office?

Yes. We wire electric panel heaters, infrared panels, or underfloor heating systems. Electric heating is the most practical option for garden offices since it doesn't require plumbing. We size the heater circuit appropriately and provide a dedicated thermostat for independent temperature control.
