Rewiring a House in Flintshire: Costs, Timeline & What to Expect

A full house rewire is one of the most significant electrical investments a homeowner can make. In Flintshire, costs vary widely depending on property size, age, access, and the level of finish you want. This guide breaks down what you can realistically expect to pay and how the process works.

For a typical 3-bedroom semi-detached house in Mold or Buckley, a full rewire costs between £3,500 and £5,500. This includes removing old cables, installing new circuits, fitting a modern metal consumer unit with RCD and surge protection, and testing to BS 7671 standards. Victorian terraces in Mold may cost more due to limited access and the need for sympathetic installation techniques that preserve original features.

Hawarden presents a unique set of challenges. The village's historic cottages and Edwardian semis often have stone walls, slate damp courses, and decorative plasterwork that makes cable routing difficult. Our Hawarden rewires use specialist techniques — lifting floorboards, routing through loft spaces, and minimal wall chasing — to protect period features. Expect to add £500-£1,000 to a standard quote for these sympathetic methods.

Deeside and Broughton properties tend to be more straightforward. Post-war semis and 1970s bungalows usually have cavity walls and accessible loft spaces, making rewires faster and less disruptive. A typical Deeside rewire takes 5-7 days for a 3-bedroom property, compared to 7-10 days for a complex Hawarden cottage.

The rewire process starts with a free visual survey. We assess your existing installation, discuss your needs, and provide a detailed quote with a room-by-room breakdown. Once accepted, we schedule the work and provide a start date. You do not need to move out — we restore power each evening and work room by room to minimise disruption.

During the rewire, we install new lighting, socket, and cooker circuits. We can add extra circuits for home offices, EV chargers, and outdoor power at the same time — much cheaper than retrofitting later. All work is Part P compliant and comes with an Electrical Installation Certificate and Building Regulation Compliance Certificate.
