Do I need a specialist electrician to install an outdoor sauna?
Yes. Electric sauna heaters pull between 4.5kW and 9kW and operate in extreme heat and moisture. A qualified sauna electrician must install a dedicated radial circuit, 170°C heat-resistant silicone cabling for Zone 3, and full 30mA RCD protection to comply with BS 7671 Section 703 regulations.
Does a garden office need its own consumer unit?
If you are running heating, multiple sockets, and lighting, yes. A dedicated sub-board in the outbuilding is safer, prevents nuisance tripping in the main house, and is the correct way to meet wiring regulations for garden office electrical installations.
Outdoor Electrics, Garden Office & Sauna FAQs
Is planning permission required for garden power or saunas?
Typically no, as outdoor electrical installations and most single-storey garden saunas (under 2.5m high near boundaries) fall under permitted development in England. However, adding permanent power requires a building regulations notification (Part P), which we handle and sign off for you.
How is the cable run to my garden office or outdoor sauna?
We use steel wire armoured (SWA) cable, buried underground at the correct depth (typically 450mm to 600mm) or run in surface conduit, such as galvanized steel or flexible metallic conduit, depending on your garden layout. This ensures maximum safety and compliance.
