About house rewiring in London

London has more homes in need of rewiring than almost any other city in the UK. The capital's vast stock of Victorian and Edwardian terraces — concentrated in inner boroughs from Islington and Hackney to Peckham and Wandsworth — contains wiring that in many cases dates from the 1950s, 1960s, or earlier. Rubber-insulated wiring installed before 1970 degrades as it ages, its insulation becoming brittle and cracked. This makes overheating and arcing faults more likely and is a significant fire risk. Electricians in London regularly find rubber-insulated cables that are completely bare of insulation where they pass through wooden joists — a condition that should be addressed as a matter of urgency.

The 18th Edition of the IET Wiring Regulations (BS 7671), which came into force in 2019, sets the current standard for all new electrical installations. All consumer units installed in domestic properties must now be metal-encased and use RCBOs or split RCD/MCB arrangements to provide individual circuit protection. When a London property is rewired, all work must comply with these regulations, and the electrician must be registered with a competent person scheme — NICEIC, NAPIT, or ELECSA — to self-certify the installation without involving Building Control. Conveyancers increasingly request sight of a Part P compliance certificate before exchange of contracts, making professional certification an essential part of any London house sale or remortgage.

FAQ

Frequently asked questions — rewiring in London

How do I know if my house needs rewiring in London?+
Signs that your London home may need rewiring include: old rubber or fabric-insulated wiring (pre-1960s), round-pin sockets, brown, red, or black wiring colours (pre-2004 colour code), a consumer unit with re-wireable fuses rather than MCBs, persistently tripping circuits, discoloured or warm sockets and switches, and an EICR result of Unsatisfactory. If your property has never been rewired and is more than 25–40 years old, an EICR inspection is strongly recommended before any major renovation or sale.
How much does a full house rewire cost in London?+
A full house rewire in London costs approximately £2,500–£4,000 for a 2-bed house, £3,500–£5,500 for a 3-bed house, and £4,000–£7,000 for a 4-bed house. These prices include a new consumer unit, all wiring, sockets, switches, and the Part P compliance certificate. Prices can be higher in larger properties, those with difficult access, or where additional circuits such as EV chargers are added. Always get at least three quotes.
How long does a house rewire take in London?+
A 1-bed flat typically takes 2–3 days to rewire. A 2-bed house takes 3–5 days. A 3-bed house takes 5–7 days. A 4-bed house takes 7–10 days. You can usually remain in the property during the rewire with some disruption — power will be off during working hours. Electricians will make good at the end of each day so the property is safe overnight.
Will I need to redecorate after a rewire?+
Yes — chasing cables into walls and ceilings means plaster damage and the need for making good after the rewire is complete. Your electrician will plaster-patch cable routes but you should budget for full redecorating. Typically £500–£1,500 for making good after a full rewire in a 2–3 bed London house, depending on the extent of the work and the condition of existing plaster.
Do I need planning permission to rewire my house?+
No — rewiring does not require planning permission. However, it is notifiable work under Part P Building Regulations. Your electrician must be registered with a competent person scheme (NICEIC, NAPIT, or ELECSA) to self-certify the work. If they are not registered, the work must be notified to and inspected by your local Building Control authority. Always use a registered electrician for a full rewire.
