If you work on commercial or CDM sites, you need 110V — a Faithfull 110V site reel or a Defender 2-gang reel both take a 16A breaker without complaint. For a straight lead rather than a drum, a Defender Yellow 110V 25m lead is the one to grab. For domestic and workshop trades, a Masterplug or Sealey 240V heavy-duty drum is the workhorse.

110V or 240V — get this right first
On most UK commercial and construction sites, mains-voltage 240V tools are banned. Site rules and CDM practice require 110V centre-tapped supply, which is why site tools, transformers and leads are all yellow.
Cable gauge and the wound-reel trap
Budget leads use 1.5mm² cable; the better ones use 2.5mm². Anything over about 15m, or anything driving a heavy inductive load, wants 2.5mm².
A tightly wound drum of cable carrying a heavy load builds up heat with nowhere to go. Always unwind the reel fully before you draw serious current, even if you only need three metres of it.
Frequently Asked Questions
Can I use a 240V extension reel on a construction site?
Generally no. Most UK commercial and CDM sites require 110V centre-tapped supply for hand tools.
Why does my reel have two different amp ratings?
One is for the reel fully unwound, the other for it wound. Coiled cable under heavy load overheats, so the wound rating is much lower — often half.
Is 1.5mm² or 2.5mm² cable better?
2.5mm² carries more current with less voltage drop, which matters over long runs and with heavy tools.
Do I need a thermal cut-out?
Yes. It’s a resettable breaker that trips before an overloaded or overheating reel becomes a fire risk.
The Verdict
Decide voltage first and the rest follows. The Faithfull FPPCR25MSEL remains the sensible 110V site reel at a fair price; the Defender lead and the Sealey 50m reel are both genuine picks, just at the pricier end of the range.
