A full rewire is one of the bigger electrical jobs a home ever needs, and prices quoted online vary wildly. As electricians working across Manchester and Greater Manchester, we see the same questions from homeowners every week. Here is an honest breakdown of what rewiring actually costs in 2026 and why quotes differ so much.
For a full rewire, which means replacing all cabling, sockets, switches, light fittings and the consumer unit, most UK homeowners pay somewhere between £3,500 and £12,000. In the North West, prices tend to sit a little below London rates, though the gap has narrowed as material costs have risen.
As a rough guide for Greater Manchester: a two bed terrace, of which Manchester has plenty, typically falls between £3,500 and £5,500. A three bed semi usually lands between £4,500 and £7,500. Larger four or five bed properties can run from £7,000 to £12,000 or more. These are ranges, not quotes, because the condition and layout of each house changes the picture considerably.
The biggest factor is access. An empty house with lifted floorboards is far quicker to rewire than a furnished, carpeted, occupied one. If you can schedule a rewire before moving in or during a wider renovation, you will usually save money and a lot of disruption.
Specification matters too. The number of socket outlets, whether you want downlights in every room, outdoor power, an electric vehicle charging point or provision for a future extension all add labour and materials. Older Manchester housing stock brings its own quirks: solid brick walls that need chasing rather than hollow stud walls, lath and plaster ceilings that are fragile to work around, and in pre war terraces, occasionally rubber or lead sheathed cable that confirms the rewire is overdue.
A typical three bed house takes five to ten working days for the electrical work itself, split into first fix, where cables are run and boxes sunk into walls, and second fix, where sockets, switches and the consumer unit go on and everything is tested. Making good the plaster afterwards adds time, whether your electrician arranges it or you use your own plasterer.
You can stay in the house during a rewire, and many people do, but expect lifted floorboards, dust and rooms without power at various points. Most electricians will work room by room and keep essentials like the fridge and one lighting circuit running overnight where possible. If you have the option to stay elsewhere for the first fix week, it makes life easier for everyone.
Not every older installation needs completely replacing. An Electrical Installation Condition Report, which typically costs £150 to £300 depending on property size, will tell you whether the wiring is unsatisfactory and why. Sometimes a new consumer unit, some additional circuits and targeted repairs are enough, at a fraction of the cost of a full rewire.
Genuine warning signs include a fuse box with rewirable fuses and no RCD protection, older rubber or fabric insulated cables, sockets mounted on skirting boards, frequent tripping or fuse blowing, and any burning smell or scorching around outlets. If your house was last wired more than 30 to 40 years ago and has never been inspected, a condition report is money well spent before you commit to anything.
A full rewire is notifiable work under Part P of the Building Regulations in England, so use an electrician registered with a competent person scheme such as NICEIC or NAPIT. They can self certify the work and you will receive an Electrical Installation Certificate and Building Regulations compliance certificate on completion. Keep both safe, as solicitors ask for them when you sell.
Get two or three itemised written quotes and check exactly what each includes. The common gaps are making good the plasterwork, redecorating, and the number of sockets per room, and these are where a cheap headline price can end up costing more. A good local contractor will walk the property with you, talk through your plans for the house, and put everything in writing before any work starts.
A full rewire is notifiable under Part P of the Building Regulations, and DIY rewiring would need Building Control involvement, inspection and testing at your own cost. In practice it rarely saves money, and uncertified work can cause real problems when you sell or claim on insurance.
Yes, a full rewire almost always includes a new consumer unit with RCD protection, as the old board would not meet current wiring regulations. If quoted separately, a consumer unit replacement on its own typically costs £450 to £800.
It rarely adds more than it costs directly, but unsatisfactory wiring flagged in a survey can knock thousands off offers or cause sales to fall through. A recent rewire with certificates gives buyers confidence and removes a common negotiating point.
