The average cost to rewire a house is made up of five key factors:
- The size of the house
- Whether it is occupied or vacant during the job
- The specification of the electrical fixtures and fittings
- The complexity of the job
The bigger the house, the more elaborate the job; and the longer the job takes, the more it will cost.
For example, the average cost to rewire a one bedroom flat is between £1,500 and £3,000 and takes around five days.
The average cost to rewire a three bedroom house is between £3,000 and £7,000 and takes between six and ten days.
And time doesn’t cost the same everywhere. The price of labour varies depending on where you live. Rewiring a house in London or the south-east will be more expensive than in the north.
Finally, you have materials. Electricians will normally quote you for white finish electrical fittings – the standard finish you see in most houses.
These five elements are what make up the standard house rewire cost from an electrical point of view – but there’s usually additional costs to take into account.
With this in mind, what are the other factors you need to consider?
