13A Black Plug to 13A Socket 1 Gang

This heavy duty 13A extension lead is a simple, reliable way to power a single appliance from a standard UK mains outlet. It is ideal for control gear, chargers, laptops, small tools, network kit, work lights, and general indoor or sheltered use where you want a lead that lasts.

Built from proper components

We build these using Masterplug Heavy Duty components, chosen for robust day to day handling. The result is a lead that feels like working kit, not a disposable DIY extension.

Practical cable build

Built with flexible cable selected to suit 13A use, keeping the lead easy to coil, store, and deploy.

Asset marking

Every lead is supplied with 12cm of clear heat shrink on both ends. It gives you a clean, durable area to add your asset ID, company name, barcode labels, colour bands, or inspection tags without it peeling off or looking scruffy over time.

Built and checked properly

We build these like working kit: bootlace ferrules for tidy terminations where appropriate, torque screwdrivers so terminations are tightened to the correct spec, and every lead is fully tested and PAT tested before it leaves us.

Length options

Stock lengths: 1m, 2m, 5m, 10m, 20m, 30m, 50m.
