Best UPS extension lead for UK plugs

Updated: October 2026

The best UPS extension lead UK shoppers can pick from this set depends on one constraint: you need British 3-pin plugs on a small UPS that only has IEC outlets, and you want a single lead rather than a basket of maybes. Best here means the strongest match for that job among seven amazon.co.uk listings we compared on 16 October 2026, not a lab ranking. The [UPS extension lead comparison](/hub/sockets-and-extension-leads/ups-extension-lead) holds the full table. Products Compared did not test these leads on a bench.

If you want the most reviewed 1 m block

The Computer Spares lead, ASIN B082VJLJLZ, with UINCLU in the brand field, is the top pick for a short run. It is 1 m, four UK sockets, a C14 plug, £11.49, and 4.7 from 647 amazon.co.uk reviews. The listing prints 10 A, 240 V, and 2,400 W, and those three figures agree. Captured reviews put it on APC UPS units, including a Back-UPS BX1400UI, and on an APC PDU. The UK-socket case is on the C14 to UK socket extension page.

If you want the longer cable for the same £5.19

The best-value pick is PRO ELEC PEL01206. It is the same job as the Computer Spares lead, with 2 m of cable, four UK sockets, and a C14 plug, at £5.19. The star line is 4.8 from 79 reviews. There is no joule rating. The bullets say 10 A, and a separate input-current attribute says 5 A. If you cannot see the label, that conflict is a reason to skip PEL01206. The 1.5 m PEL01205 is £10.58. Take that length only when you measured 1.5 m and the cheaper leads are unavailable.

When a white block or a C13 lead is the better object

Mercury's white 1 m lead, £7.11, claims 10 A and a strain-relief collar. The average is 4.1 from 10 reviews. Choose it when the desk is white and a black block would show, and when you accept a thin sample. The KC CABLE lead is the better object when nothing you care about has a UK plug. It is 2 m, C14 male to C13 female, £8.99, and it cannot feed a plug-top router. The C14 to C13 or UK sockets page is the fork if you are still unsure which shape you own.

What we will not call a winner

We will not call any lead the safest. Listing claims stay claims, and star ratings stay amazon.co.uk averages. For UK plugs, take the Computer Spares 1 m lead when the review sample is worth £11.49 and the devices sit close to the UPS. Take PEL01206 when 2 m at £5.19 is the clearer buy and you have read the 5 A attribute. Take neither when the devices already use kettle leads.

Common questions

Which lead has the most UK reviews in this set?
The Computer Spares 1 m C14-to-4-gang has 4.7 from 647 amazon.co.uk reviews. The next largest sample is PRO ELEC PEL01204, the 1 m block at £5.19, with 4.6 from 207 reviews. PEL01206, the 2 m lead at the same £5.19, has 4.8 from 79. Mercury has 10 reviews, the KC CABLE lead 17, PEL01205 14, and Flomiara one.
Is the cheapest 2 m lead a worse cable because it costs £5.19?
The price does not prove the cable is worse, and it does not prove it is better. PEL01206 has a higher star average than the £11.49 lead and no repeated failure in the texts we saw. It also has far fewer reviews, an input-current line that says 5 A beside a 10 A claim, and comments that the plastic is only adequate. Judge it on those facts, not on the idea that a low price must mean a reject.
Who should not buy the Computer Spares lead?
Skip it if you need about 2 m, if £11.49 is hard to justify against a £5.19 2 m lead, or if you want a switch and an indicator. Also skip it if the brittle-plastic reviews and the broken-on-arrival report are enough to put you off, or if you need a C13 extension rather than UK sockets. The 13 A printing reported by buyers is a reason to stick to 10 A, not a reason to load it harder.
Is the white Mercury the one to pick for a visible desk?
It is the only white 4-gang in this set, at 1 m and £7.11, with a strain-relief collar claimed. The review sample is 4.1 from 10 reviews, and one of the two texts calls the quality short of the best. Pick it for colour when the black leads would show, and not because it has the strongest feedback or the lowest price.
Does best include the C13 extension?
Only when your devices already use kettle leads. For UK plugs, the C13 lead cannot win, because it has nowhere to put a BS 1363 plug. The KC CABLE 2 m lead is the relevant C13 extension in this set, at £8.99, with the 3,750 W figure set aside. The Flomiara splitter is a further special case: two C13 outputs from one C14, one review, £10.59.
Can I treat 4.7 stars as a safety test?
No. The 4.7 from 647 reviews tells you that many buyers found the Computer Spares lead did the UPS job they bought it for, and that a minority reported brittle plastic, odd current marks, or a short cable. It is not a British Standard test report.
Why avoid the 1.5 m PRO ELEC if I want 1.5 m?
Avoid it when the 2 m lead will reach and can be dressed so it is not a trip hazard, because that 2 m lead is £5.19 and this 1.5 m lead is £10.58. Buy the 1.5 m lead when that is the length you measured, the cheaper lengths are out of stock, and you accept 14 reviews with a single captured text. The mounting praise in that text is not a large reliability record.
