House Rewiring in Treharris

A full house rewire replaces all the electrical wiring in your home — bringing it up to current BS 7671 standards and making it safe for the demands of modern electrical living. Older homes across South Wales, particularly those built before the 1980s, often contain ageing rubber or aluminium wiring that has deteriorated with age, lacks adequate earthing, or simply cannot safely support the electrical load that modern households place on a system. Our electricians carry out full and partial rewires across Merthyr Tydfil and the wider South Wales region with care and professionalism, causing as little disruption as possible to your home.

The rewiring process typically takes 5–7 days for a standard three-bedroom property. During the first fix, our team runs new cables through walls, floors, and ceilings, installing back boxes for sockets, switches, and lighting positions throughout the house. During the second fix, all the accessories are fitted, the new consumer unit is installed, and the full installation is rigorously tested to confirm it meets current standards before we apply for the Part P Building Regulations certificate.

We understand that having workmen in your home for a week can be stressful, which is why we work as neatly and considerately as possible. We protect your floors and furnishings, use dust sheets in work areas, and clear up thoroughly each day. We also discuss cable routing with you in advance so that the amount of redecoration required is minimised — and we always advise honestly on what will need making good after we have finished.

A complete rewire adds real value to your home and is often a condition of sale or remortgage where a surveyor has flagged the condition of the existing wiring. If you have received an unsatisfactory EICR report citing extensive C1 or C2 defects, a full rewire is almost always the most cost-effective and permanent solution.
