Quick Answer

A full house rewire in London costs £2,800-£14,000 depending on property size. Every circuit is replaced, a new 18th-Edition consumer unit is installed with one RCBO per circuit, and a BS 7671 Electrical Installation Certificate is issued within 24 hours of completion. Typical lead time is 5-12 days on site. Work is notifiable to Building Control under Part P and self-certified through NICEIC.

What is a full house rewire?

A full rewire replaces every fixed cable, every accessory and the consumer unit in a property, leaving you with a brand-new electrical installation certified to BS 7671:2018+A2:2022 — the current 18th Edition Wiring Regulations. It is the standard remedy for properties with rubber-insulated wiring (pre-1965), early PVC-sheathed cabling with degraded insulation (1965-1980), wooden-backed consumer units, no RCD protection on sockets, or a string of C1/C2 codes on the latest EICR.

Every rewire we carry out is signed off by a NICEIC registered electrician holding current 18th Edition and City & Guilds 2391 inspection and testing qualifications. Work is notified to Building Control under Part P of the Building Regulations 2010 via NICEIC self-certification — no separate borough application is required. The Building Regulations Compliance Certificate is posted to you within 30 days.

Pricing is fixed in advance based on property size, number of circuits, age of the building and access. No daywork, no hourly creep, no surprise extras. Period properties with lath-and-plaster walls carry a 10-15% make-good surcharge.

What we cover in every rewire

Every fixed-price quote spells out the same scope — there is no “basic” tier that drops testing or certification. The line items below are included as standard:

  • Strip-out and disposal of existing cabling, accessories and consumer unit
  • New twin-and-earth cabling throughout to BS 6004, drops chased into walls and clipped above ceilings
  • New 18th-Edition (BS 7671:2018+A2:2022) metal consumer unit with RCBO per circuit
  • Brushed-chrome or white moulded sockets and switches as specified — like-for-like positions or repositioned
  • Interlinked mains-powered smoke alarms on each floor and heat alarm in kitchen to BS 5839-6 Grade D
  • Dedicated cooker, hob, oven and immersion circuits sized to BS 7671 diversity tables
  • Main earth bonding to gas and water service, supplementary bonding in bathrooms
  • Plaster make-good of chases, patching of holes and basic redecoration on cut lines
  • Full dead and live testing on every circuit — continuity, insulation resistance, Zs, RCD trip times
  • BS 7671 Electrical Installation Certificate (EIC) issued within 24 hours, NICEIC notified to Building Control

How a rewire works — start to finish

1

Free survey & fixed quote

An electrician attends, measures circuits, checks the supply, asks where you want sockets and switches, and emails a fully itemised fixed-price quote within 48 hours. No surveyor fee, no obligation. The quote covers materials, labour, plaster make-good, testing and certification.

2

First fix — cabling

Power is isolated, floors are lifted, walls are chased and the entire new cable network is run back to the new consumer unit position. We use Megger MFT1741 test gear on every circuit before any plastering begins. First fix is typically 2-6 days depending on property size.

3

Second fix — accessories & test

Sockets, switches, ceiling roses, alarms and the consumer unit are installed. Every circuit is dead-tested, then live-tested with the supply on. RCBO trip times are recorded at 1× and 5× rated residual current. Power is restored circuit-by-circuit.

4

Certification & sign-off

The Electrical Installation Certificate (EIC) is issued within 24 hours of completion, the work is notified to Building Control via NICEIC under Part P of the Building Regulations, and a compliance certificate is posted out within 30 days. A 12-month workmanship guarantee starts on the day of sign-off.

When do you need a full rewire?

Most London rewires are triggered by one of five situations. If any of the conditions below apply to your property, a full rewire is usually the only economic remedy — patching individual circuits past a certain point costs more than starting again.

  • • Rubber-insulated cable — installed in UK homes before 1965. The rubber dries out, cracks and the live conductor becomes exposed. Insulation resistance falls below 1 MΩ and the installation fails any EICR.
  • • Early PVC cable (1965-1980) — green-and-yellow earth not used consistently, sheath becomes brittle, sockets without earth pins still present. Often fails on polarity and earth continuity.
  • • Wooden or plastic consumer unit — no RCD protection on socket circuits, BS 3036 rewireable fuses still in use, no main switch isolation. Codes C2 on every EICR.
  • • Multiple C1 or C2 fails on a recent EICR — patching three or more circuits is rarely cheaper than a rewire once labour, materials and a new consumer unit are added up.
  • • Major refurbishment or extension — if walls are already open and a kitchen / bathroom is being renovated, the marginal cost of full circuits is small compared to the value added at sale.

Certification, Part P and Building Control

BS 7671 Electrical Installation Certificate issued after a full house rewire in London

A full rewire is “notifiable work” under Part P of the Building Regulations 2010. That means it has to be either inspected by Building Control during the work, or carried out by a contractor on a Part P self-certification scheme like NICEIC. We do the latter — no separate borough application, no Building Control inspection fee, no waiting on appointments.

Two documents land in the post or inbox at completion. The Electrical Installation Certificate (EIC) is the BS 7671 model form carrying the schedule of circuits, test results, signatures and the NICEIC registration number — issued within 24 hours. The Building Regulations Part P Compliance Certificate is posted by NICEIC within 30 days and confirms the work is notified to your local authority. Keep both with the property deeds — your conveyancer will ask for the Part P certificate at sale.

Areas covered

Full rewires are carried out across all 32 London boroughs and the City of London. Heaviest booking volumes come from Camden, Westminster, Islington, Hackney, Tower Hamlets, Southwark, Lambeth and Wandsworth.

Frequently Asked Questions

How much does a full house rewire cost in London?
A full rewire in London costs £2,800–£3,800 for a 1-bed flat, £3,200–£4,500 for a 2-bed, £4,500–£6,500 for a 3-bed house, £6,500–£9,500 for a 4-bed and £9,500–£14,000 for a 5-bed or larger property. Every quote is fixed before work starts and includes the new 18th-Edition consumer unit, RCBOs on every circuit, BS 7671 testing, the EIC certificate and basic plaster make-good. VAT is included.
How long does a full rewire take?
Lead time is typically 5-12 days on site depending on property size and access. A 1-bed flat is a 5-7 day job. A 3-bed house is 8-12 days. A 5-bed period property with lath-and-plaster walls and limited access can run 14-18 days. We confirm the exact programme in writing with the quote and stick to it — penalty clauses are accepted on contracts over £10,000.
Do I need to move out during a rewire?
Not always. Most occupied rewires are done floor-by-floor or room-by-room with rolling isolations, so you keep a working kettle, lights and Wi-Fi in the parts of the property not being touched that day. Whole-property isolations are limited to 4-6 hours and scheduled in advance. For tenanted property a void-period rewire is faster (5-9 days) and avoids the disruption entirely.
Is a rewire notifiable to Building Control?
Yes. A full rewire is notifiable work under Part P of the Building Regulations. As NICEIC registered electricians we self-certify the work and notify Building Control directly through the NICEIC notification portal — you do not need to apply to your borough separately. The Building Regulations Compliance Certificate is posted to you within 30 days of completion and is the document your conveyancer will ask for at sale.
What does the rewire include?
Every quote includes: strip-out of existing wiring, new BS 6004 twin-and-earth cabling to every circuit, a new 18th-Edition metal consumer unit with one RCBO per circuit, all new sockets and switches, interlinked mains-powered smoke and heat alarms to BS 5839-6 Grade D, main earth bonding to gas and water, full BS 7671 dead and live testing, the EIC certificate and basic plaster make-good of chases. EV charger pre-wiring and underfloor heating circuits are optional extras quoted line-by-line.
Will you make good the plaster?
Yes — basic plaster make-good of all chases and switch-box cut-outs is included as standard. Final skim and decoration is normally done by a decorator afterwards because the timing depends on your colour scheme. For period properties with lath-and-plaster walls a 10-15% surcharge covers the slower, more careful make-good required to avoid wider damage.
Can I add EV charger or solar wiring at the same time?
Yes, and doing it during the rewire is usually 30-50% cheaper than retrofitting later because the cable runs and consumer unit space are already open. A typical 7.4 kW EV charger feed adds £350-£550 to the rewire quote. A solar / battery pre-wire (DC isolators, AC isolator, MID meter spare way) adds £400-£700. Both are quoted as separate line items on the original fixed-price quote.
What certificate do I get at the end?
A BS 7671 Electrical Installation Certificate (EIC) is issued within 24 hours of completion. The EIC carries the schedule of circuits, the test results for every circuit, the inspector's signature and the NICEIC registration number. Separately, a Building Regulations Part P Compliance Certificate is posted by NICEIC within 30 days. Both documents are required at point of sale and by most home insurers — keep them with the property deeds.
Do you guarantee the work?
Yes. Every rewire carries a 12-month workmanship guarantee from the day the EIC is issued. The NICEIC Platinum Promise sits behind that — if the contractor goes out of business or refuses to remedy defects within the guarantee period, NICEIC arranges remedial work directly. The work is also fully insured under our £5m Public Liability cover with Hiscox UK.
Can you rewire a tenanted property?
Yes. Tenanted rewires are scheduled during a void period (between tenancies) where possible, because a 5-9 day uninterrupted programme is significantly faster and cheaper than working around occupants. Where the property must stay occupied we work floor-by-floor with rolling isolations, written notice to tenants and a dedicated site supervisor. A fresh EICR is issued at sign-off and can replace the existing 5-year landlord certificate.
