Pricing factors
What affects the price?
Property size & type
More rooms mean more cable, accessories and labour. Detached homes also cost more than flats because of longer cable runs and harder access.
Wiring condition
Original 1960s rubber or lead-sheathed cable takes longer to remove than modern PVC. If your property has been partially rewired already, the job is quicker.
Fuse board upgrade
Replacing an old fuse box with a modern RCBO consumer unit is usually included in a full rewire, but can also be done separately for £650–£1,200.
Extra circuits
EV chargers, garden supplies, outdoor sockets and smart-switch systems all add dedicated circuits that push the price up — but future-proof your home.
Finish & redecoration
We make neat chased channels and refill them, but you may still need a decorator afterwards. Some homeowners opt for full plaster repair, which is extra.
