Rewiring Costs UK 2026

When you need a rewire

Houses wired before the late 1960s often have old rubber or lead-sheathed cables that are now unsafe. Signs you may need a rewire include old-fashioned round-pin sockets, fabric-wrapped cables, frequent tripping, or an outdated fuse box with rewireable fuses. An Electrical Installation Condition Report (EICR) from a qualified electrician will tell you definitively.

Typical price ranges by property size (UK 2026)

Rewire costs scale with the number of rooms, sockets and light points. Larger homes also need a bigger consumer unit and more circuits. These ranges include labour, cables, accessories (sockets, switches, light fittings) and a new consumer unit, but prices rise in London and the South East.

• •Full rewire, 1-bed flat / house: £2,000–£3,500.
• •Full rewire, 2-bed house: £2,500–£4,500.
• •Full rewire, 3-bed house: £3,000–£6,000.
• •Full rewire, 4-bed house: £5,000–£8,000.
• •Full rewire, 5-bed house: £7,000–£10,000+.
• •Consumer unit (fuse board) replacement alone: £400–£700.
• •Adding a new socket or light point: £80–£150 each.

Keeping costs down

Rewiring is very disruptive — floors lifted, walls chased. Doing it before you decorate or as part of a larger renovation saves you decorating twice. Plan socket and switch positions carefully up front, because moving them later means chasing walls again. Always use an electrician registered with a Part P competent person scheme (NICEIC, NAPIT or similar) so the work is self-certified and you get the right compliance certificate.
