A full rewire is one of the biggest electrical jobs a home ever needs, and quotes can vary by thousands of pounds. This guide sets out realistic figures for Greater Manchester, explains what actually drives the price, and helps you judge whether a quote is fair.
For most homes in and around Manchester, a full rewire currently lands somewhere between £4,000 and £12,000. A two bed terrace, of which there are thousands across areas like Levenshulme, Gorton and Salford, typically comes in at £4,000 to £6,500. A three bed semi usually runs £5,500 to £9,000, while a larger four or five bed detached or a big Victorian property can reach £10,000 to £15,000 or more.
These figures normally cover stripping out the old wiring, installing new cables, sockets, switches and light fittings, a new consumer unit, and the testing and certification at the end. What they usually do not cover is redecorating. Rewiring means chasing cables into walls and lifting floorboards, so budget separately for plastering repairs and paint.
Two houses of the same size can get very different quotes, and there are usually good reasons for it. The biggest factors are how many circuits and accessories you want, how easy it is to get cables around the building, and whether anyone is living there during the work.
Manchester's older housing stock adds its own quirks. Solid brick walls take longer to chase than modern plasterboard, lath and plaster ceilings are slow to work around, and some pre war terraces still have shallow floor voids that make running cables under floors fiddly. An empty house is quicker and cheaper to rewire than a furnished, occupied one, often by 10 to 20 percent.
Age alone is a strong clue. If your home still has a fuse box with rewirable fuses, rubber or fabric insulated cables, or round pin sockets, the installation is likely 50 years old or more and overdue for replacement. Other warning signs include sockets that feel warm, frequent tripping or blown fuses, flickering lights and any burning smell near outlets.
The sensible first step is an Electrical Installation Condition Report, known as an EICR. This typically costs £150 to £300 depending on the size of the house and gives you an independent assessment of what, if anything, needs doing. Sometimes a partial rewire or a new consumer unit is enough, which costs a fraction of a full job.
Get at least two or three itemised quotes and check each one lists the number of sockets and light points, the consumer unit specification, and whether making good the plaster is included. A quote that is thousands cheaper than the others has usually left something out, most often the plastering or the certification.
Any full rewire is notifiable work under Part P of the Building Regulations, so use an electrician registered with a scheme such as NICEIC or NAPIT who can self certify and issue an Electrical Installation Certificate. Expect the work itself to take five to ten working days for an average three bed house. If you are planning a kitchen refit, extension or loft conversion, it is worth rewiring at the same time, since the disruption overlaps and you avoid paying twice for making good.
You can, but it is disruptive, with power off in sections and floors up in most rooms. Many people move out for the messiest first fix stage, and an empty house usually means a faster and slightly cheaper job.
A rewire rarely adds more than it costs on its own, but old wiring flagged in a buyer's survey can knock more off your sale price than the rewire would have cost. New wiring with a valid certificate removes that negotiating point entirely.
A properly installed rewire should last 40 to 50 years, though the consumer unit may be upgraded sooner as regulations change. Periodic inspections every ten years, or five for rented properties, keep the certification current.
