Frequently Asked Questions
How much does it cost to rewire a 3-bed house UK?
Rewiring a 3-bed semi-detached house typically costs £3,500-£5,500 including new consumer unit, all circuits, sockets, switches, testing and certification. Making good (plastering) is usually extra at £500-£1,000.
How long does it take to rewire a house?
A 2-bed flat takes 4-5 days. A 3-bed house takes 5-7 days. A 4-bed house takes 7-10 days. You can usually stay in the house during rewiring but will have no power in rooms being worked on.
How do I know if my house needs rewiring?
Signs include: old round-pin sockets, fabric-covered cables, no RCD protection, frequent blown fuses, burning smells from sockets, and a fuse box rather than a modern consumer unit. Houses with wiring over 25-30 years old should be inspected.
