This deal is expired. Here are some options that might interest you:

Great extension reel for use around the garden or around the house. Perfect for all uses with a thermal cut out which can be easily reset.

Bought one a couple of years ago for £20 and thought I'd get another at this price (I've not seen it this cheap in the last few years!).

I think it's free shipping, but have had an Amazon account for years, so not sure if it's only for prime, but when I signed out of my account, it didn't add any delivery charges to my order.

just £2 more at £20 in b&q for those who don't have prime
Don't waste you're money, these are awful.
These are no use around the house really, need to be fully uncoiled before using. Ideal for large garden etc.
Looking for a cheap 10m extension if anyone knows the best place, 4 gang, ideally.

Why do they need to be fully uncoiled?

Potential overheating issue

All extension leads should be fully uncoiled

What causes the cable to get to hot when it's coiled? Surely the amperage drawn would have to be somewhere near max for this to happen otherwise every reeled extension lead would come with a safety warning. Plus this one comes with a safety thermal cut out.

Interesting read. Although as it says all extension reels sold in Europe have to comply to safety standards which should prevent such action. The disaster shown is a cable on a cable reel with no protection & it is not stated how much load was present on the cable for the sheathing to come so hot to melt.

No idea. Was just answering the question.

I have used these type of reels loads without uncoiling them. Never had an issue

One thing you need to be very careful with is long extension leads, and, "daisy chaining" of leads, if you're really interested in the mathematics google it, there's thousands of pages on it.
electricalsafetyfirst.org.uk/gui…ds/


  • Overuse of multi-way adapters or adapter blocks, which increases the risk of fire
An extension lead should only be used when it is not possible to reach a wall socket with the equipment cable. When the use of an extension cable is unavoidable – follow these simple suggestions:

  • Only use an extension lead which was bought ready-assembled.
  • We recommend that no extension lead be more than 15 metres long.
  • Only use extension leads fitted with suitably insulated connectors and plugs. (Never join two lengths of flexible cable by twisting the bare ends of wires together.)
  • Position an extension lead carefully to prevent any risk of damage.
  • If the cable has to cross a pathway, cover it with a rubber protector strip.
  • Always check that leads, plugs and sockets are undamaged.
  • Always check the extension lead plug contains the correctly rated fuse for the equipment being used.
  • If using a cable drum extension lead, it should be completely unwound to avoid overheating.
  • For general use, 2-core extension leads should not be used.
I spoke to an electrition at work about needing to uncoil an extension lead and he told me there was no need for it as the draw on the lead wouldn't be enough to make it overheat to a temperature that would cause a fire. I thought that would be the case because I've worked on loads of jobs where builders leave most of the cable in the roll and have stuff plugged into it permanently for weeks on end
I've used this exact lead for approx 5 years. Works fine. Albeit my brother's just told me about the cable unwinding issue. Never had a problem and used it with a safety cut out with a lawn mower with no issue.
I'm not one for boasting but mine is 50mtrs long, and by the sounds of it also dangerous
All this deal has taught me is the potential for a TV series called, "But will it burn [down the house]?". The show would feature numerous brands and various ways of daisy-chaining extension leads with sharp cuts to UKHD experts such as Harley_Mick and Deedie. Each episode would conclude with illy1965's mate "The Spark" providing expert advice such as "throwing water on electrics is a myth".


Anyway, bought 4 of these so I can charge my phone at the end of the street.
When the cable.is coiled up there is a restriction on the surface to dissipate heat. This will be relative as previously said to current drawn but can cause overheating. I'm surprised the electrician said is doesnt matter about being coiled up given that the rating factor for a flexible cable is down rated based on the number of winds round a drum

I have no problem with getting my extension lead hot, when coiled. So whereas your electrician is right that it should not catch the fire, it will trip overheat feature, meaning your extension will stop working until it cools down. Got this with my power washer. I was well annoyed because I was in rush. So lesson learnt, I always unwind extension, unless I power low power tools (angle grinder, drill for short periods of time, etc.)

This specific extension states max 720W when wound up, my other extensions are more like 1.2kW...
