In the electrical trade, margins are tight and deadlines tighter – but cutting corners on materials is never worth the risk. Nowhere is this truer than with cable, where not all products are created equal.
At SED Ltd, we’re often asked why one roll of twin and earth might be cheaper online than from a local wholesaler. The truth? Cheaper cables often cut corners on copper content, sheathing thickness, or even fail to meet UK safety standards. That may not be obvious on the reel, but it matters – especially when those cables are being installed in homes, schools or workplaces.
Poor-quality cable can cause overheating, arcing, and faults that damage appliances or worse. We’ve seen it firsthand: trades called back to fix issues caused by inferior materials they didn’t realise they were installing.
We only stock cable from trusted UK suppliers that meet or exceed British Standards. You won’t find unbranded, untested knockoffs on our shelves. Whether it’s meter tails, flex, SWA, or twin and CPC, our stock is fully traceable and quality-assured.
The same goes for everything else we supply – from sockets to consumer units. We deal with reputable manufacturers who stand behind their products, so you can stand behind your work.
When you buy from SED, you’re not just buying stock – you’re investing in long-term reliability, fewer call-backs, and peace of mind for your customers. Our team is always here to advise on the right product for the job and help source anything non-standard quickly.
Quality isn’t just about materials – it’s about service, too. Need cable by the drum? Pre-cut lengths? Delivered to site? We’ve got you covered.
