Telephone Cable

Tel wire is common shorthand for telephone cable, and we stock telephone and data cable for running phone extensions and data points around the home or office. All of it is white, so it sits neatly along skirting and trunking, whether you are adding a point or replacing tired cabling. Our notes below will help you choose the right cable for the sockets you are connecting.

Telephone and data cable for the home or office

This is the low-voltage wiring that feeds phone points and data outlets around a building. Run it for a new socket, extend an existing point, or replace tired cable that has seen better days. The reels here cover the common builds for both phone and basic data runs.

Telephone cable pairs and cores explained

Telephone cable is counted in pairs, where each pair is two conductors twisted together. The range offers two pair and three pair builds, giving you the conductors a phone point needs with some spare for extension or repair. A flat four core data cable is also stocked for straightforward data points.

Copper-clad steel construction

The twisted-pair builds use copper-clad steel conductors, a steel core with a copper surface. The steel adds strength so the thin wires hold up to being pulled and clipped along a run, while the copper carries the signal. It is a sensible choice for the light loads a phone or data point places on the cable.

White on 100m reels

Every build comes in white on a 100m reel, so the cable sits neatly along skirting and inside trunking where you would rather not see it. Working from a full reel means you can run the cable from point to point in one length and trim only what you need.

Choosing the right build of telephone cable

Pick the build by the outlet you are wiring. The two pair and three pair cables are aimed at phone points, with the three pair giving extra conductors for spare or repair, while the flat four core build is intended for basic data points. Matching the cable to the socket keeps the job straightforward.

Ready for new runs or replacements

Whether you are wiring a fresh point or swapping out old cable, these reels are ready to clip into place. Free delivery worldwide on all orders over £99.

Frequently Asked Questions

Is tel wire the same as telephone cable?
Yes, it is simply a shortened name for telephone cable, the cable that carries a phone line from your master socket to extension points around a home or office. On this page we stock telephone and data cable, all of it in white.

How much tel wire do I need?
Measure the route from your master socket to the points you are adding, following skirting, door frames and trunking rather than a straight line. Allow a little extra for corners and for connecting at the sockets, so you can finish the run without joins. Keep it apart from mains cables along the way, and ask a qualified electrician where it has to cross them.

What is the difference between pairs and cores in telephone cable?
A pair is two conductors twisted together, and each conductor is a single core. So a two pair cable holds four cores in two twisted pairs, and a three pair cable holds six. The flat four core data cable here is counted in cores rather than pairs.

What does copper-clad steel mean?
Copper-clad steel is a conductor with a steel core and a copper outer skin. The steel adds strength so the thin wire resists stretching and breaking when it is pulled and clipped, while the copper surface carries the signal.

Can I use this cable to extend an existing phone point?
Yes. The two pair and three pair builds suit extending or replacing phone wiring, and the reel gives you length to run from the existing point to the new one. Cut only what the run needs and keep the remainder for later.

Is telephone cable run on the surface or hidden?
It is usually clipped along skirting or routed inside trunking so it stays out of sight. The white finish helps it blend in against pale skirting and walls.

Should the data cable and the telephone cable be used differently?
The twisted-pair builds are aimed at phone points, while the flat four core build is intended for basic data points. Choose the one that matches the outlet you are wiring.
