How Much Does It Cost to Rewire a House? (UK Guide 2026)

Rewiring is one of those jobs most homeowners only face once or twice — so it's hard to know what a fair price looks like. This guide covers typical UK rewiring costs in 2026, what's actually included, the difference between a full and partial rewire, and how to tell whether your home needs one at all.

Typical house rewire costs in the UK (2026)

Every property is different, but as a rough guide for a full rewire including a new consumer unit, testing and certification:

Property size Typical cost range Typical duration
1-bed flat £2,500 – £4,000 3–5 days
2-bed house £3,500 – £5,500 5–7 days
3-bed house £4,500 – £7,500 6–10 days
4-bed house £6,000 – £9,500 10–14 days
5-bed house £8,000 – £12,500+ 2–3 weeks

Ranges are indicative for 2026 and vary by region, property condition and specification. The only way to get an accurate figure is a survey and fixed quote.

What affects the cost of rewiring?

  • Occupied vs vacant — working around furniture, carpets and a family living in the house takes longer than an empty property mid-renovation.
  • Access and construction — solid floors, high ceilings and older lath-and-plaster walls all add labour.
  • Specification — number of sockets and lighting points, smart controls, outdoor circuits, EV charger provision, or data cabling.
  • Making good — quotes usually include chasing and first-fix plastering, but full redecoration is normally separate. Always check.
  • Consumer unit and protection — a modern board with RCBO protection and surge protection is now standard for a quality rewire.

Full vs partial rewire

You don't always need the whole house done. A partial rewire — replacing the oldest circuits, upgrading the consumer unit, or wiring a new kitchen or extension — can be the right call where parts of the installation are already in good condition. An inspection will tell you which route makes sense; we'll never recommend a full rewire where a partial one will do.

Signs your house may need rewiring

  • Frequent tripping, blown fuses or flickering lights
  • An old fuse box with rewirable fuses or no RCD protection
  • Scorch marks, buzzing sockets or a burning smell
  • Rubber, fabric or lead-sheathed cables (common pre-1970s)
  • Too few sockets and extension leads everywhere
  • No earth on lighting circuits

The definitive answer comes from an Electrical Installation Condition Report (EICR) — from £200 + VAT — which grades the condition of your wiring and tells you exactly what (if anything) needs doing.

Certification and Building Regulations

Rewiring is notifiable work under Building Regulations Part P. Using a registered electrician means the work is self-certified, tested to BS 7671, and you receive an Electrical Installation Certificate — documents you'll need when you sell the property and for your insurance. All our work is carried out by NAPIT-registered electricians.
