How Much Does a Rewire Cost in 2025?

The honest answer is that rewire costs vary significantly, and anyone quoting a firm price without seeing the property is guessing. The main variables are property size, the condition of the existing wiring, and how accessible the walls and ceilings are.

What affects the price

Property size is the biggest single driver. More rooms means more circuits, more cable runs, and more time on site. A one-bedroom flat has a fraction of the wiring of a four-bedroom house.

The condition of existing wiring matters too. Rubber-insulated wiring from the 1960s and 1970s often needs full removal rather than being left in place, which adds time. If a property has aluminium wiring, common in some 1970s builds, that comes out entirely.

Whether the property is occupied affects how the work is staged. An empty property is faster. In a lived-in home, we work room by room to keep disruption manageable, which extends the overall programme.

Cable routing varies by construction type. Solid walls, insulated cavities, and concrete floors each have different implications for how cables are run. A flat with concrete intermediate floors is harder to rewire than a Victorian house with original timber floorboards that lift cleanly.

The finish required plays a role. Some customers want the walls made good as the work progresses. Others are planning to redecorate and prefer us to work quickly and leave the finishing to their own trades. Both are reasonable approaches, and the second is cheaper.

Typical price ranges

For a rough guide only, with prices to be confirmed by a site visit and written quote:

• A one or two-bedroom flat or small house: towards the lower end of the rewire market
• A three-bedroom semi-detached property: typically quoted in the range of £4,000 to £7,000
• A four to five-bedroom detached house: often between £7,000 and £12,000, sometimes more

These ranges are wide because the variables above genuinely move the cost. A quote based on a proper site visit will always be more reliable than any number read online.

What is included

A full rewire includes replacing all fixed wiring in the property: ring final circuits, lighting circuits, a cooker circuit where one exists, and any specialist circuits for electric showers or immersion heaters. It includes a new consumer unit with full RCD or RCBO protection throughout. At the end of the job you receive a Part P completion certificate and an Electrical Installation Certificate, both of which are required to comply with Building Regulations and both of which your solicitor will ask for when you sell.

What is not included

Rewiring involves lifting floorboards, cutting cable channels in walls, and accessing ceiling voids. Reinstating the plasterwork, plastering, and decorating afterwards are not included in a rewire quote unless specifically discussed and agreed. Most customers arrange their own plasterer and decorator once the electrical work is complete.

How to get an accurate quote

Ring and describe the property: number of bedrooms, approximate age of the wiring, whether the property is occupied, and whether you are working to a deadline. We will arrange a site visit to assess the installation and provide a written, itemised quote. That quote does not change unless the scope of work changes.
