How many sockets can I safely run off one UK extension lead?

A UK 13A plug is rated for a total load of 3,120W across whatever you plug into the lead. So you can run a TV, a soundbar, a Sky box and a couple of phone chargers off a single 4-gang without trouble. The rule that breaks people is high-draw appliances: a kettle, a heater, a microwave or a hair dryer can each pull 2,000W on their own. Two of those on the same lead trips the fuse and warms the cable in a way that should not happen. Keep high-draw kitchen and heating gear on a wall socket; reserve the extension lead for AV and chargers.

Is it safe to plug an extension lead into another extension lead?

Don't. The London Fire Brigade and most landlord guides flag this as a common cause of domestic electrical fires — daisy-chaining stacks the current draw on a single 13A plug at the wall, and if anyone forgets and plugs a kettle in down the chain, the load can exceed what the cable is rated to carry. If you need more sockets in one place, buy a single lead with more gangs or a small tower. If you need sockets further from the wall, get a longer lead, not a second one bridging the gap.

Do I really need USB-C built into an extension lead?

Not yet on every lead, but ideally on at least one. Most phones and tablets sold in the UK since 2024 charge over USB-C — and from late 2024 the EU rule on a common charging port has pushed almost all new portable kit that way. Having one extension lead with a built-in USB-C port means you can throw the charging brick into a drawer and free up a mains socket. For the other leads, USB-A is still fine — most households still have a handful of USB-A cables knocking about for older devices, Kindles and small speakers.

Will an extension lead damage my landlord's wiring?

No, as long as you don't overload it. A good-quality lead with a 13A fuse and a thermal cut-out fails safely — the fuse blows before anything cooks. The risk to wiring comes from running heavy appliances chronically off undersized leads, particularly thin 5A travel leads dragged in from abroad. Stick to leads sold for the UK market with a moulded BS 1363 plug and a 13A fuse, and you're protecting the wiring rather than threatening it. If you ever smell hot plastic, unplug first, ask why second.

Remote-control sockets sound flaky — are they actually reliable?

The good ones are. The technology is straightforward 433 MHz radio, the same idea as a garage door opener — it has been around for thirty years and works through a couple of plasterboard walls without grief. The weak link is always the remote itself, which is small, light and easy to lose; buy a set that includes a spare or accepts a phone-app pairing as a backup. The sockets themselves are rated for normal household kit (typically 2,400W) so they handle lamps, Christmas lights and even a small heater, but not a kettle. Use them for the things you want to switch from across the room.

Extension Leads for UK Rentals With One Socket Per Wall — 5 Picks From £10 to £20

I have rented six UK flats in twelve years and every single one of them had the same fault: one mains socket per wall, almost always behind the sofa. The Edwardian conversion in Walthamstow had three sockets in the whole front room. The new-build in Reading put two next to the TV and exactly none on the wall the desk was going to live on. You learn quickly that the right extension lead matters more than the lamp, the speaker or whatever you're trying to plug in.

I have replaced extension leads, melted one, lost two to a moving van and finally settled on a small rotation that does the job without looking like prison-cell wiring. Below are the five I keep buying when a tenancy starts — desk, telly, bedside, and that one corner that should have had a lamp and never did.

If you only buy one: the 6-way lead with USB-C at around £10 covers a desk, a side table or a sitting-room corner without needing a charger brick in sight. Add a six-pack of USB wall plugs for everywhere else.

How I'm thinking about this

Cheap leads are fine for a lamp; they are not fine for a kettle on a long cable. A 13A British plug is rated for 3,120W and that is the ceiling — chain a 2,200W kettle, a 1,000W heater and a microwave off the same gang and you'll trip the fuse before lunch, possibly cook the cable. So I split jobs:

High-draw stuff (kettle, toaster, heater, microwave) — wall socket, never a lead.
The desk and AV nest — a tower or strip with built-in USB and a switch I can actually reach.
The "should have had a lamp here" corner — the lazy fix is a remote-control socket, not a longer cable.
Bedside, kitchen, hallway phone-charging zones — individual USB wall plugs, not trailing leads.

Surge protection is nice; an on/off switch you can hit without crawling matters more. Cable length matters too — a 1.6 m lead from the only socket behind the sofa won't reach the corner you actually wanted to sit in. Measure first.

The picks

1. The workhorse — All-in-One Charging Hub with 6 Sockets and USB-C · £10.15

6-way extension lead with three USB-A ports and one USB-C port on the side.

Six UK sockets, three USB-A and a single USB-C, all built into one strip with fire-retardant ABS housing and a 2 m flame-retardant cable. The Type-C port is the bit that earns it the spot: nearly every new phone, laptop and Bluetooth speaker in my flat charges off USB-C, and being able to plug straight in without a brick frees up the actual mains sockets for the things that need them. Rated up to 2,400W, so happy to run a desk PC, two monitors and a lamp.

Where it's only okay: the 2 m cable is fine for most desks but stops short of reaching a far-wall corner — measure before buying. The strip layout takes up more horizontal space than a cube, which is annoying on a small bedside table. Best for: the home-desk setup that's collected a charger zoo over the last two years.

2. The behind-the-telly tower — 4-Gang Extension Lead with 4 USB Ports · £19.99

A vertical four-gang extension tower with four USB-A ports and a master switch.

The vertical tower format is the one that makes sense behind a TV unit or in the corner of a sitting room where three different chunky plug bricks are fighting for the same horizontal strip. Sockets sit on different faces so a Sky box plug and a soundbar adapter don't shove each other off the lead. Smart current detection on the USB side means it actually delivers a useful charge to a phone rather than the dribble basic strips give you, and a master switch on the front lets you cut the lot when you're going away for a long weekend.

Caveats: at 1.6 m the cable is short for a sitting room, and the tower needs about 7 cm of clearance on top — if it's hidden under a low TV unit, the top sockets are useless. Best for: the AV-corner pile-up most UK sitting rooms end up with.

3. The desk cube — Two-Socket Extension Lead with USB · £19.99

A small cube-shaped two-socket extension lead with five USB ports and a front switch.

Two UK sockets and five USB ports — two USB-A and three on the side — in a small square block with a switch on the front. The reason I keep coming back to the cube shape: it sits on a desk corner without taking over and without the wobbly stack of bricks a strip ends up with. The two mains sockets handle a monitor and a laptop charger; the five USB ports handle phones, a Kindle and the random Bluetooth thing currently looking for charge. A front-facing switch is genuinely useful on a desk — strip switches always end up on the floor, which is the same as not having one.

Where it falls short: only two mains outlets, so it's a poor pick for an AV nest. The brick housing also blocks the adjacent wall socket if you plug it in low. Best for: the desk in a bedroom or living-room corner where you've run out of charger ports.

4. The lamp-and-fairy-lights pick — Remote Control Socket Set · £16.65

Two remote-control UK plug socket adapters and a small handheld remote.

Two UK plug-through adapters and a single handheld remote, 30 m range, 2,400W rating. This isn't really an extension lead — it's the proper fix for a side-table lamp or a string of Christmas lights plugged into the one socket behind the sofa you can't reach. Click the remote from across the room and the lamp comes on. Sounds gimmicky until you're sat down on a Sunday with a cup of tea you don't want to put down to walk across the room.

Real caveat: not for high-draw kit. I keep mine for two lamps and the Christmas tree, nothing else. The remote is a bit of cheap plastic and will probably die before the sockets do — keep the receipt. Best for: renters who can't be bothered fitting smart bulbs into a fitting they don't own.

5. The stash-them-everywhere buy — 6-Pack UK USB Wall Plugs · £16.99

Six small white UK 3-pin plugs with USB-A ports stacked together.

Six identical compact UK plugs with a USB-A port each, white casing, about the size of a £2 coin. Not fast. Not clever. But six is the right number when you stop trying to find "the charger" every morning — one stays by the bed, one by the kettle, one in the hallway, one in the bag, one for guests, one for the car charger that never quite reaches the lounge. Genuinely sorted.

The honest limits: USB-A only, no USB-C, and they cap out around 5W per port — slow for a modern phone, fine for an overnight bedside charge or a Kindle. Best for: households where finding a charger is currently a small daily argument.

Side-by-side

Pick	Price	Sockets / USB	Best for
6-way USB-C lead	£10.15	6 mains + 3 USB-A + 1 USB-C	Home desks, all-in-one
4-Gang Tower	£19.99	4 mains + 4 USB-A	Behind a TV unit
Two-Socket Cube	£19.99	2 mains + 5 USB	Desk corner, small footprint
Remote Socket Set	£16.65	2 plug-through + remote	Lamps and fairy lights
6-Pack USB Plugs	£16.99	6 × single USB-A	Bedside, kitchen, hallway

What to look for (and what to avoid)

Cable length. Anything under 1.5 m is a bedside-only lead. If you're snaking it round furniture, you want 2 m minimum. Measure with a tape, not your eye.
Switch position. Master switch on the top or front, not on the side. The side switch always ends up against the skirting board.
USB-C on at least one lead in the flat. Even if you don't need it today, half the household will be on USB-C within a year. Buy once.
Don't daisy-chain. Two extension leads plugged into each other is how you cook a cable. If you need more sockets, get a single bigger lead or move the heavy load to the wall.
Skip "surge protected" as a tick-box. Plenty of cheap leads claim surge protection from a single MOV inside. Worth having, not worth paying double for.

The verdict

If you're starting a new tenancy and want to be done in one go, the 6-way USB-C lead handles the main desk or sitting-room corner, the 6-pack of wall plugs spreads charging across every other room, and the remote socket set fixes the one lamp that's permanently out of reach. Total: under £45, and the flat finally works the way you wanted it to. If you've got a real AV setup, swap the 6-way for the 4-gang tower and you're sorted.
