How Much Does It Cost to Rewire a 3 Bed House?

What you can expect to pay

For a standard three bedroom semi or terrace in the Lincoln area, a full rewire usually lands somewhere between £4,500 and £7,500 including materials, labour and certification. Larger detached properties, or homes with extra rooms, an outbuilding or a loft conversion, can run to £8,000 or more.

Those figures assume a complete first and second fix: new consumer unit, new cabling throughout, sockets, switches, smoke alarms and testing. A partial rewire, where only certain circuits are replaced, will obviously cost less but is only worth doing where the rest of the installation is genuinely sound.

• Small terraced 3 bed: roughly £4,500 to £5,500
• Typical semi: roughly £5,000 to £6,500
• Detached or extended home: £6,500 to £8,000+

What actually drives the price

The biggest single factor is access. An empty property where floorboards are up and walls are bare is far quicker to wire than an occupied home full of furniture, fitted carpets and a kitchen that has to stay usable. Older Lincolnshire stone and solid wall properties also take longer than newer cavity builds because chasing cables into thick walls is slow work.

The number of points you want matters too. Modern living means more sockets, USB outlets, outdoor power, electric vehicle provision and data cabling, and every addition adds labour and parts. Making good afterwards, plastering and redecorating, is frequently left out of electrical quotes, so always check whether it is included.

Timing it with the rest of your works

The cheapest and least disruptive time to rewire is during a wider renovation, before plastering and flooring go down. If you are already taking a kitchen or bathroom back to brick, or converting a loft, folding the rewire into that programme saves money and mess.

As a renovation business we often coordinate the electrical first fix around joinery, plumbing and plastering so everything happens in the right order. A rewire on its own typically takes five to ten working days for a three bed home; done alongside other trades it rarely adds much to the overall timeline.

Signs your home genuinely needs it

Not every old house needs a full rewire, and a good electrician will tell you honestly. That said, certain warning signs are worth acting on rather than patching over.

• A fuse box with rewireable fuses or no RCD protection
• Black rubber or fabric coated cabling, common in pre 1970s homes
• Round pin sockets, sockets mounted in skirting, or very few sockets per room
• Frequent tripping, flickering lights or a burning smell near outlets
