Outdoor & Garden Electrics

Outdoor electrics cover garden sockets, lighting, supplies to sheds and garden rooms, and hot tubs. Because water and weather raise the risks, every outdoor circuit needs RCD protection and weatherproof, IP-rated fittings, and most work must be done by a qualified electrician.
This guide covers outdoor sockets, garden lighting, outbuilding supplies, hot tubs, safety rules and costs — for homeowners in the North West.
A bit of power in the garden transforms how you use it — from lighting and mowing to garden offices and hot tubs. But gardens across Manchester, Yorkshire and Lancashire see plenty of rain, and water plus electricity means outdoor work has stricter safety rules than indoors. Here’s what’s involved.

What You Can Install Outdoors

Outdoor electrics cover a wide range of popular additions:
    • Weatherproof sockets: for mowers, pressure washers, heaters and festive lighting.
    • Garden lighting: from path and patio lights to feature lighting.
    • Outbuilding supplies: power to sheds, garages and garden rooms.
    • Hot tubs: a high-power appliance needing its own dedicated supply.
    • Water features and ponds: with their own specific requirements.
Whatever the project, the same principle applies: outdoor electrics must be designed for the elements, not just adapted from indoor kit.

The Safety Essentials

Two things matter most for any outdoor installation: RCD protection and weatherproofing.
    • RCD protection: every outdoor circuit must be protected by a 30mA RCD, which cuts the power in milliseconds if it detects a fault — for example, if you cut through a cable.
    • IP rating: outdoor fittings carry an Ingress Protection rating for dust and water. IP44 is the minimum, with IP65 or IP66 better for exposed spots.
    • Armoured cable: outdoor and buried runs use steel wire armoured (SWA) cable for mechanical protection.
    • Dedicated circuit: best practice is a separate circuit from the consumer unit, so a garden fault doesn’t affect the house.
This is why outdoor work isn’t a DIY job — the consequences of getting it wrong in a wet environment are serious.

Outdoor Sockets and Lighting

A weatherproof outdoor socket is one of the most useful and affordable additions. It saves trailing extension leads out of a window and gives you safe, permanent power for tools, lighting and seasonal use. A proper outdoor socket is sealed against water and protected by an RCD. Garden lighting follows the same rules — fittings must be IP-rated for outdoor use, and the circuit RCD-protected. For anything beyond a simple plug-in set, fixed wiring by an electrician is safer and tidier.

Sheds, Garages and Garden Rooms

Running power to an outbuilding is a bigger job, and one of the fastest-growing requests as more people add garden offices. A garden room used as an office or hobby space typically needs its own dedicated circuit, often a radial supply sized for lighting, sockets and heating, with its own protection. The supply is usually run in armoured cable, buried or clipped along a safe route, and the work is notifiable — so it must be done properly and certified.

Hot Tubs

Hot tubs are popular, but they’re a serious electrical load that needs careful planning. A full-size tub typically draws a lot of current and needs a dedicated supply hardwired from the consumer unit — it can’t simply run off a standard plug socket. That often means a spare way at your fuse box, or an upgrade if there isn’t one. Our guide to consumer unit upgrades covers when that’s needed. As with all outdoor work, RCD protection and weatherproofing are essential.

Costs and the Rules

Costs vary widely with the job. A single weatherproof outdoor socket is usually an affordable, quick job — often somewhere around £85–£245 depending on location and access. Bigger projects like a garden room supply or hot tub circuit cost more, as they involve dedicated circuits and longer cable runs. On the rules: most new outdoor circuits are notifiable under Part P of the Building Regulations, meaning the work must be done by a registered electrician or notified to building control. A registered electrician handles this as part of the job.

Why Choose a Professional Installer?

    • Weatherproof design: the right IP-rated fittings and cable for outdoors.
    • Correct protection: proper RCD protection on a dedicated circuit.
    • Part P compliance: notifiable work certified to current standards.
    • NICEIC approved: work carried out to recognised standards.

Frequently Asked Questions

Do outdoor sockets need to be RCD protected?

Yes. Every outdoor circuit must be protected by a 30mA RCD, which cuts the power within milliseconds if it detects a fault — for example, if a cable is cut. This is a firm requirement for all outdoor installations, with no exceptions.

What IP rating do I need for outdoor electrics?

Outdoor fittings should be at least IP44, with IP65 or IP66 recommended for exposed locations. The IP rating shows how well a socket or fitting resists dust and water — the higher the number, the better the weather protection.

Can I install an outdoor socket myself?

It’s not advisable. New outdoor circuits are notifiable under Part P and must be installed by a registered electrician or notified to building control. Given the added risks of water and weather, outdoor electrical work should always be left to a professional.

How much does an outdoor socket cost to install?

A single weatherproof outdoor socket typically costs around £85–£245 depending on location and access, and is usually a quick job. Larger projects like a garden room supply or hot tub circuit cost more, as they need dedicated circuits. Last updated: June 2026
