Rewiring for Extensions

Rewiring for extensions is about more than just "adding a few extra sockets." When you build out a new room or commercial space, the existing electrical system has to be carefully assessed so it can safely carry the extra demand without nuisance tripping, overheating, or future restrictions on what you can plug in. With 15 years on the tools and full NICEIC Approved Contractor status, I design and install extension wiring that feels like it has always belonged to the building, but meets today's standards.

I start by looking at how you plan to use the new space - home office, open‑plan kitchen, extra bedrooms, or additional office desks - then I size circuits, protective devices, and cable routes accordingly. That means enough sockets in the right places, sensible lighting control, and proper provision for appliances, data, and future EV or smart upgrades, not just the bare minimum to pass an inspection.

Every extension rewire I carry out ties neatly and safely into the existing installation, with RCD and surge protection where required, correctly rated breakers, and full testing at the end. I use quality branded accessories, clear labelling, and tidy containment, so maintenance and any future alterations are straightforward.

Whether your project is a small rear extension on a house or a larger commercial fit‑out, I coordinate with your builder and other trades to avoid clashes, protect finished surfaces, and keep the programme on track. Once complete, you receive the proper NICEIC certification and building control paperwork, giving you and your insurer confidence that the new wiring is safe, compliant, and ready for long‑term use.
