Wall mounted extension lead: what to check before you buy

Updated: October 2026

You are about to buy a strip for the gap behind a desk or a television, and the title is offering extra sockets, a wattage, and often USB or the word surge. A wall mounted extension lead is still one portable bar. You can screw it to a wall, a desk, or a pegboard, and the Type G plug still goes into one existing socket. The [wall mounted extension lead comparison](/hub/sockets-and-extension-leads/wall-mounted-extension-lead) sets out the nine amazon.co.uk listings. We read those pages and public guidance from Electrical Safety First and BEAMA on 16 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

What you are actually buying

What you are buying is a multi-way strip with slots, holes, or brackets, not a new circuit. The outlets share the fuse in one BS 1363 plug. A title that says 3,250 W is 13 A at 250 V. At a nominal 230 V that is about 2,990 W for the bar. The mount is a hanger: rear slots on the PIBEEX, rear screws on the DEWENWILS, keyholes on the toomke, and 180° brackets on the Alpheus. Marking the holes is on the how to wall mount an extension lead page.

Six checks before you pay

Check the mount the listing names. On the TOPREK 3-way, some rear slots are tight or missing the hanging groove, and screws are not supplied. A standard UK plug is an approved BS 1363 type with a BS 1362 fuse. Only the PIBEEX bullet says BS1363/A. BEAMA also wants at least 1 mm² up to 2 m, and 1.25 mm² or 1.5 mm² on a longer lead. None of these nine prints a conductor size. USB totals are shared. Surge counts when a joule number is printed.

Where these nine listings are vague

The DEWENWILS safety bullet says 270 joules, while the surge attribute says 13 Amps. The PIBEEX attribute says two USB ports, and the bullets never describe them. The toomke file has review texts and no Customer Reviews star line. The ROOTOMA, ANVODE, BOCHLION, and Alpheus say surge and print no joules. The Alpheus also leaves the cable length off the page. The TOPREK bars print 1,800 J and at least 2,100 J. Both are wood-effect plastic. None of these nine states an IP rating.

When a mounted strip is the wrong product

The strip is the wrong product when you need more than one 13 A socket. Daisy-chaining does not add capacity. Metal brackets do not make a distribution board, and the garage page keeps that limit. Buy one of these nine only when a real mount, a 13 A plug, a believable length, and, if you need surge, a joule number are printed.

Common questions

Does screwing a wall mounted extension lead to the wall turn it into fixed wiring?
No. The bar is still a portable extension lead. The Type G plug goes into one existing wall socket, and you should be able to unplug it. Slots, end holes, or rack brackets hold the body up. They do not add fuses or circuits. A new socket or a spur is different work, and that is a job for a registered electrician.
Is a printed 3,250 W more capacity than a 13 A UK socket?
No. On these listings, 3,250 W is 13 A times 250 V, written as the total for the whole strip. UK mains are nominally 230 V, so the same 13 A is about 2,990 W. Everything on the bar shares that budget. A kettle around 3 kW, as a rule of thumb, can use the strip on its own.
What should the plug and the socket be marked with?
Look for a BS 1363 plug with a BS 1362 fuse. BEAMA's checklist also asks you to see "BS 1363/A" on the socket. In this set, only the PIBEEX bullet prints BS1363/A. The Alpheus bullet claims UKCA and CE and does not name BS 1363. If the mark is missing from the listing, treat it as not stated.
How long a cable do these listings actually state?
The ROOTOMA states 1.5 m. The ANVODE and both TOPREK models state 2 m. The PIBEEX, DEWENWILS, and toomke state 3 m, though one PIBEEX review measured about 1.5 m. The Alpheus does not state a length. The BOCHLION title says 3 m, a bullet says 2 m, and reviews measure about 1.7 m. None of the nine prints a conductor size.
What does a USB total such as 5 V at 3.1 A mean?
It means the ports share that total. A higher figure for one USB-C or USB-A port is not available on every port at once. On the BOCHLION, PD 30 W is one USB-C port. The other ports are listed at 5 V / 3.4 A. The ROOTOMA's stated total is 24 W / 4.8 A across six ports, not 24 W on each one.
When is the word surge not a joule rating?
When the page never prints joules. A 13 A fuse or the words "overload protection" limit current. They do not state surge energy. The DEWENWILS bullet says 270 J and the attribute says 13 Amps. The BOCHLION and Alpheus say surge and print no joules. The TOPREK bars print 1,800 J and at least 2,100 J.
Can you use one of these strips in a bathroom?
No. Electrical Safety First says not to run an extension lead into a bathroom. An ordinary socket should be at least 2.5 m from the edge of a bath or shower tray. None of these nine states an IP rating. Socket work inside a bathroom zone is for a registered electrician, not a longer lead and a pair of screws.
