If your consumer unit still has rewirable fuses, your sockets are scorched round the edges, or a survey has flagged old wiring, you are probably weighing up a full rewire. Prices vary a lot between homes, so this guide sets out realistic figures for Birmingham properties and explains exactly what pushes the cost up or down.
For most Birmingham properties, a full rewire tends to land somewhere between £3,500 and £8,500 including materials, a new consumer unit and certification. A two bed terrace in areas like Erdington, Stirchley or Yardley is usually at the lower end, around £3,500 to £5,000. A three bed semi, which makes up a huge share of the city's housing stock, typically comes in at £4,500 to £6,500. Larger four or five bed homes in places like Sutton Coldfield, Moseley or Harborne can reach £7,000 to £10,000 or more, particularly older Victorian and Edwardian houses with high ceilings, solid walls and original lath and plaster.
These are guide figures rather than quotes. Two identical looking semis can price very differently once you factor in the number of circuits, whether the house is occupied during the work, and how much making good is included. Always get an itemised written quotation after a proper walk round, not a price over the phone.
A rewire is priced mainly on labour time, and labour time is driven by access and layout. Chasing cables into solid brick walls, which most pre war Birmingham houses have, takes far longer than clipping through modern stud walls. Fitted kitchens, laminate or tiled floors, and loft insulation all slow the work down because everything has to be lifted, protected or worked around.
The specification matters too. Every extra socket, downlight circuit, outdoor supply or electric shower adds cost. Many customers use a rewire as the moment to add USB sockets, kitchen appliance circuits, an EV charger supply or wiring for a future extension, which is sensible because doing it later costs far more.
A full rewire of a three bed house usually takes five to ten working days with two electricians, followed by plastering repairs. First fix involves lifting floorboards and chasing walls, so it is dusty and disruptive. If you can move out, even for the first week, the job goes faster and often costs slightly less. If you stay, expect the work to be done room by room with power restored each evening.
Building work like this must be notified under Part P of the Building Regulations. A registered electrician self certifies the work and you receive an Electrical Installation Certificate plus a Building Regulations compliance certificate. Keep both safe, as solicitors will ask for them when you sell the house.
Not every older installation needs ripping out. Rubber or fabric insulated cable, a fuse box with no RCD protection, or cables run in the old black and red colours with signs of damage are strong indicators that a rewire is due. But plenty of 1980s and 1990s installations just need a new consumer unit and some additional circuits, which might cost £500 to £1,200 rather than several thousand.
The honest starting point is an Electrical Installation Condition Report, which typically costs £150 to £300 for a Birmingham house. It grades every defect and tells you whether the wiring is genuinely unsafe or simply dated. Be wary of anyone who recommends a full rewire without testing the installation first.
Most three bed semis in Birmingham cost between £4,500 and £6,500 to fully rewire, including a new consumer unit and certification. Solid walls, occupied properties and higher specifications push the figure up, so get an itemised quote after a site visit.
Yes, though it is disruptive. Electricians usually work room by room and restore power each evening, but expect around a week or more of dust and lifted floorboards. Moving out for the first fix stage, if possible, speeds the job up.
It varies, which is why quotes differ so much. Some electricians include filling the chases only, while others price for a plasterer to make good every wall. Check exactly what making good is included before comparing quotes.
