How Much Does It Cost to Rewire a House?
£3,000 – £12,000
depending on property size
The cost to rewire a house ranges from £3,000 for a small terraced property to £12,000 or more for a large detached home, depending on the number of rooms, circuits, and how much existing wiring needs replacing. Full rewires are typically necessary in properties where wiring is over 25 years old, uses outdated rubber or aluminium wiring, or where an EICR has identified serious defects.
Average cost
£3,000 – £12,000
depending on property size
Prices vary by region, property type and tradesperson. Always get at least two quotes.
What affects the price?
Property size - a 2-bed terraced house costs £3,000-£5,000; a 5-bed detached can cost £8,000-£12,000+
Number of circuits and sockets - more circuits, sockets, and lighting points mean more cable and labour time
Ease of access - properties with accessible floors and loft space are cheaper to rewire than those with solid concrete floors
Making good - filling and patching chased channels should be in the quote; redecorating is a separate cost and can add significantly
Labour vs materials
Labour accounts for approximately 60-70% of the total cost of a rewire. Electricians typically work in a team of two, and a full rewire on a 3-bed semi takes 5-7 days.
Repair or replace?
If only one circuit or a section of wiring is faulty, a partial rewire of that circuit is possible and far cheaper. A full rewire is only recommended when the entire installation is outdated, unsafe, or cannot be certified.
