How Much Does It Cost to Rewire a House?

A starting price can help with early planning, but an accurate rewiring quotation needs a survey and an agreed specification.

Property size matters, although the layout, access and electrical requirements can be just as important.

Spark’s Indicative Starting Prices

2-bedroom property — From £4,000

3-bedroom property — From £4,500

4-bedroom property — From £5,000

These are indicative starting prices for full rewiring. All prices are subject to survey and property-specific requirements. Partial rewiring is quoted for the specific work required.

What Affects the Final Price?

The number and positions of sockets, switches and lighting points affect the installation scope.

Access to cable routes, the property’s layout and protection requirements also need consideration. Whether the home is occupied can influence preparation and how the work is organised.

What Should the Quotation Explain?

Look for a clear description of the wiring, circuits, accessories and any consumer unit work included.

The quotation should also identify inspection, testing and certification, together with relevant exclusions. Confirm whether plastering, decoration and other making good are included.

Ask for the total payable and any applicable VAT treatment to be made clear.

Agreeing Changes

Additional electrical points or newly identified requirements can change the scope. Agree the effect on price before extra work proceeds.
