A garden power post puts a mains socket where you actually need it: by the terrace, next to the pond pump, at the far end of the lawn or beside the drive. An outdoor socket post is a short weatherproof column, usually 25–50 cm high, with one or two hinged-lid sockets near the top and a cable fed to it underground. It saves you from running extension leads across the grass every time you mow, plug in string lights or charge a hedge trimmer.
Posts are usually aluminium, extruded or die-cast, and powder-coated in black, graphite, white, grey or rust-toned finishes so they match nearby outdoor wall lights and bollards.
| Feature | Typical value | Why it matters |
|---|---|---|
| Socket standard | Type E or Schuko (type F) | Your plugs must fit; UK three-pin plugs do not fit these sockets |
| Number of sockets | 1–2 | Two sockets let a pump and lights run side by side |
| Protection | IP44–IP54 | Hinged lids keep rain out of sockets not in use |
| Maximum load | Up to 16 A, about 3500–3600 W in total | The limit is for the whole post, not each socket |
| Height | 25–50 cm | Taller posts are easier to use and stay drier |
| Through-wiring | Terminals for up to 3 × 4 mm² | Several posts can be fed from one buried cable |
The socket standard is easy to overlook. Many posts sold across continental Europe carry type E or Schuko sockets, which accept the round two-pin plugs used on most European appliances. Check the product page and compare it with the plugs of the tools and lights you plan to use.
A power post is part of the fixed mains installation, so it must be connected by a qualified electrician. The circuit should be protected by a 30 mA RCD, and the buried feed is normally an armoured or suitably protected cable laid at a safe depth and marked with warning tape. The post itself is fixed to a concrete base, a ground anchor or a mounting plate through holes in its foot. Plan the cable route before laying a new terrace or path, so you are not lifting paving later.
Keep the lids closed when nothing is plugged in, and do not leave a plug in the socket under a lid that cannot close over it during heavy rain. Clear soil and mulch away from the base so water drains off. Once a year, look for cracked lids and check that the RCD trips when you press its test button. Avoid running heavy loads such as a heater and a pressure washer at the same time from one post.
Fixing the post in place is simple, but connecting it to the mains, laying the cable and adding RCD protection is work for a qualified electrician.
Yes. Outdoor circuits should be protected by a 30 mA RCD, which cuts the power quickly if current leaks to earth, for example through a damaged cable.
Usually an armoured cable or a cable in a protective duct, sized by the electrician for the load and the length of the run.
To light the same spot, see bollard lights and mounts for garden lamps.
