How To Run Electrical Wire Through Finished Walls In The UK

Living life in the 21st century often means adapting technology and electrical wiring to suit our modern needs. Many homeowners, DIY enthusiasts and professional tradespeople in the UK are faced with the daunting task of manoeuvring electrical wires through finished walls. It can be a laborious, time-consuming and cost-intensive job, but luckily there are a few practical tips and tricks to help you get the job done quickly and safely. Here we look at a few easy-to-follow methods for running electrical wire through finished walls in the UK.

Plan Ahead

The first and perhaps most crucial step in running electrical wire through finished walls is proper planning. If you’re running multiple lengths of wire, make sure that each run is designed to be level, straight and as short as possible. This will also help minimize the risk of snagging or tangling the wire which could potentially cause a hazard. When selecting the route for the wire, take into account the location of existing wiring, studs, fire-stops, insulation, other obstacles and any potential building regulations you will have to comply with.

Use Bending Tools

Running wire through finished walls requires patience and precision. Investing in high-quality tools such as an adjustable conduit bender, wire snake and a small hand saw will help to make the job much easier. The conduit bender allows you to bend the pipe to follow the contours of the wall while the wire snake can be used to push the wire through tight spaces and avoid snagging. A hacksaw blade can then be used to start a hole in the wall that is suitable for the conduit to enter.

Wall Entry & Sealing

Once you’ve cut your entry hole for the wire, ensure that it’s wide enough to fit the conduit and the wire without pinching in or causing strain on the wiring. It’s also important to seal the gap, usually with a high quality sealant or foam insulation, to ensure that the wall remains structurally sound and soundproofed.

Protection & Labelling

Finally, always ensure that all electrical wiring runs inside approved conduit, such as steel conduit or PVC pipes. This not only helps protect the wiring from damage, but it also helps meet the requirements of the Building Regulations which state that wiring must be in a “suitable flexible conduit”. Once the wire is in place, label the runs so that you know where each one goes and clearly mark the power source in case future maintenance is required.

By following these easy-to-follow steps and investing in the right tools you can quickly and safely run electrical wire through finished walls in the UK. This will save you time, energy and money in the long run, and ensure that all of your wiring is safe and meets building regulations.
