Rewiring done properly — certified, compliant, and built to last 40 years.
Full house rewiring, consumer unit upgrades and electrical installation across East London and the Home Counties. Part P registered, BS 7671 compliant, NICEIC-certified throughout.
Most electrical problems are hidden until something goes wrong. We find them first.
Older electrical installations are the most common cause of house fires in the UK. Rubber-insulated wiring, oversized fuses, no RCD protection, earthing that was never properly done — these are not minor issues. They are active risks to life and property. Most people only find out when they are selling, remortgaging, or when something actually fails.
RCB carries out full rewires properly — new cabling throughout, a modern consumer unit with RCD and RCBO protection, correctly earthed metalwork, and every circuit tested and verified against BS 7671 (IET Wiring Regulations 18th Edition). The result is an installation that passes any inspection, satisfies any mortgage lender, and will not let you down for the next four decades.
We work methodically to minimise disruption — taking one area at a time, protecting carpets and furniture, making good as we go. Most occupied rewires are completed in 5–10 days. You know what is happening each day, and we do not leave you without electricity overnight.

How It Works
The RCB process for this service.
Electrical Survey
We carry out a full inspection of your existing installation — assessing age, condition, earthing, protection and capacity. You receive a clear report on what needs to be done and why.
Scope & Fixed Quote
A fully itemised quote covering every circuit, every consumer unit component and every outlet. No day-rate guesswork — you know the cost before we start.
First Fix Rewire
All new cabling chased, clipped or surface-run throughout the property. Consumer unit installed. First fix tested before any decoration or second fix begins.
Second Fix & Certification
Sockets, switches, light fittings and accessories fitted. Full installation test carried out, EICR issued, Part P notification filed. Electrical Installation Certificate provided.
Planning & Regulations
Electrical rewiring is notifiable work under Part P of the Building Regulations in England. All work must be carried out by a Part P-registered contractor and notified to the local authority — certificates must be in place for any future sale or remortgage. All RCB electrical installations comply with BS 7671 (IET Wiring Regulations 18th Edition, Amendment 2). Consumer unit installations in domestic premises must use metal enclosures as required by Amendment 3 of the 17th Edition (now incorporated into the 18th Edition). An Electrical Installation Certificate (EIC) is issued on completion of new installation work.
FAQs
Common questions.
How much does a full house rewire cost in London?
A full rewire for a 2-bedroom flat typically costs £3,000–£5,000. A 3-bedroom house typically costs £4,500–£7,000. A 4–5 bedroom house £6,000–£10,000 or more. Costs depend on property size, access conditions, specification and whether the consumer unit requires upgrading. RCB provides a fixed price following a site survey — no day-rate guessing.
How long does a full house rewire take?
Most rewires take 5–10 working days. A 2-bedroom flat can typically be completed in 4–6 days; a 4-bedroom house in 7–10 days. RCB works methodically through the property so you are never left without electricity overnight and disruption is minimised.
Do I need to move out during a rewire?
Not necessarily. RCB works through the property in sections, restoring power at the end of each working day. You can remain in the property during most rewires, though expect disruption — floors up in places, walls chased and dust. If the property is vacant, works can be completed faster and with less disruption to manage.
What is BS 7671 and why does it matter?
BS 7671 is the national standard for electrical installations in the UK, published by the IET (Institution of Engineering and Technology). It is the legal baseline that all electrical work must meet. NICEIC-approved contractors work to BS 7671 and are regularly assessed to confirm compliance. All RCB electrical work is carried out to the current 18th Edition (2018) including all amendments.
What is an EICR and do I need one?
An Electrical Installation Condition Report (EICR) is an inspection of an existing electrical installation to assess its safety and compliance. It is required for rental properties (mandatory every 5 years), recommended on purchase of any property built before 1990, and required by some mortgage lenders and insurers. If your installation fails an EICR, the recommended action is usually a partial or full rewire. RCB carries out both EICRs and the remedial work.
