How Much Does It Cost to Rewire a House?

Updated July 2026

A rewire is a big job you'll rarely do more than once. Here's what it costs in Renfrewshire, how long it takes, and how to know if your home needs one.

Typical costs

A full rewire of a 3-bed home in Renfrewshire typically costs £3,000–£6,000, depending on size, access and how much making-good (plaster/decor) is needed afterwards. Partial rewires cost much less.

Older fabric cabling, frequent tripping, scorch marks around sockets, or a very old fuse board are signs a rewire (or at least an inspection) is due.

What to expect

A full rewire takes around 5–7 days and is disruptive (floorboards up, chases in walls), so many people combine it with other renovation work.

All work must be done by a registered electrician and certified. Every electrician on TrustVault is registration-checked before they can quote.

Frequently asked

How do I know if I need a rewire?

An EICR (safety inspection) will tell you. Fabric-insulated cabling, an old fuse board, or frequent tripping are common warning signs.

Can I rewire one room at a time?

Yes — partial rewires are possible and cheaper, though a full rewire is often better value if the whole system is old.
