Partial Rewire
North London
Worried you'll get pushed into a full rewire when only a few circuits are unsafe? We honestly assess the installation, replace only what's failing, and re-test — saving you thousands compared to a full house rewire. Single circuits, kitchen-only, ground-floor or EICR-flagged remedials — all tested, certified and notified to Building Control.

Rewiring Problems We Solve Without Unnecessary Work
We identify which circuits are actually unsafe or unsuitable, then explain whether a targeted partial rewire can resolve the problem without replacing sound wiring.
“Will you push me into a full rewire I don’t need?”
No — we inspect the entire installation before recommending anything. If only specific circuits are unsafe, we'll say so and price only those. Most properties built or rewired after 2005 only need targeted partial work, not a full strip-out. If a partial genuinely solves it, that's what we quote — even though a full rewire would be a bigger ticket for us. See House Rewiring North London for when a full job is the right call.
“Can you fix my failed EICR without rewiring everything?”
Yes — that's the most common partial rewire we do. We work from your EICR report, target the specific C1 and C2 coded circuits, replace cable and accessories on those circuits only, then re-test and issue a fresh EICR plus an Electrical Installation Certificate for the remedial work. C3 codes are quoted separately if you want to address them at the same time.
“Can I stay in the property during the work?”
Yes — unlike a full rewire, a partial only affects the circuits being replaced. The rest of your property stays powered. We schedule any planned outages in advance and almost always restore power the same day. Single-circuit jobs typically finish in a day; multi-circuit partials in 2–3 days.
“How much will this actually cost?”
Single-circuit partial rewires start from £950. Kitchen-only partials from £1,500. Multi-circuit jobs (half house, ground floor, all bedrooms) typically £1,800–£3,200. Compare that to a full house rewire from £4,500. For a budget breakdown by property size, see our House Rewire Cost Guide.
“Will the certificate satisfy a mortgage lender or letting agent?”
Yes — we issue a Minor Works Certificate or full Electrical Installation Certificate for the rewired circuits, plus an updated EICR for the whole installation if you need one. We provide the applicable electrical certificates and, for notifiable work, the Building Regulations documentation. A lender, conveyancer, letting agent or insurer decides which documents it requires for the individual property.
“Can you do it without trashing the decoration?”
We minimise damage by routing through floor voids, lofts and existing chases wherever possible. On single-circuit work we often manage with no plaster damage at all. On multi-circuit jobs some chasing is unavoidable — we patch with bonding plaster ready for your decorator. We never quote skimming or paint — that's the decorator's trade, not ours.

Five Signs You Don't Need a Full Rewire
Most homeowners are quoted for a full rewire when a targeted partial would fix the same problem at a fraction of the cost. If any of these apply to your property, ask for a partial first.
Your wiring is mostly post-2005
If your property was built or rewired after about 2005, the cabling is almost certainly modern PVC twin-and-earth, RCD-protected via a plastic or metal consumer unit, and compliant with the 17th or 18th Edition. Insulation doesn't degrade like the rubber and lead cabling in pre-1970s installations — so wholesale replacement isn't justified. A targeted partial fixing damaged sections, plus a consumer unit upgrade if needed, brings the installation back into compliance for a fraction of a full rewire.
Only the kitchen circuit is failing
Kitchens take the heaviest hammering of any part of the wiring — ovens, hobs, kettles, dishwashers and washing machines all draw hard on shared circuits often designed for 1970s usage. If the rest of the house tests fine on EICR, a kitchen-only partial is the right answer. We replace the kitchen ring, install dedicated oven and hob supplies, fit a grid isolator and re-certify — from £1,500. See Kitchen Rewiring North London for the full scope.
Your EICR has C2/C3 codes on specific circuits, not the whole installation
An EICR coded "unsatisfactory" with two or three C2 entries doesn't mean the whole installation is dangerous — it means specific circuits failed and need attention. We work directly from the EICR schedule of items, replace cable and accessories on the flagged circuits only, then re-test and re-issue a satisfactory report. This is the cheapest, fastest route to mortgage-lender or letting-agent compliance.
The bathroom or shower has been unsafely wired
Bathroom electrical zones (Zone 0/1/2) have stricter rules than the rest of the house — IPX-rated fittings, RCD protection, supplementary bonding. A previous DIY job or pre-2005 install often fails on zone compliance alone. We carry out a zone-based partial: rewire the bathroom circuit, fit IP-rated zone 1/2 lighting, install proper RCD/RCBO protection, and certify — without disturbing the rest of the house. Typically £950–£1,500 depending on access.
You're upgrading for a single new appliance
Adding a new electric oven, an induction hob, a hot tub or a home office subboard? You don't need a rewire — you need a circuit extension. We add a new dedicated circuit from your consumer unit (or fit a small subboard), size the cable to the load, and certify the addition. Usually a one-day job, and a fraction of the cost of full property rewiring. If your existing fuse box can't accept new ways, see Consumer Units North London for the upgrade route.
How We Complete Your Partial Rewire
Targeted, scope-limited rewiring from start to finish. Single-circuit jobs typically finish in a day; kitchen-only partials in 1–2 days; multi-circuit jobs in 2–3 days.
Free Site Survey & EICR Review
We visit your property to assess the existing installation, review your EICR (if you have one), test the circuits in question, and confirm exactly which circuits need replacing — and which don't. This survey is completely free with no obligation.
Scope Agreement & Fixed Quote
You receive a written scope listing exactly which circuits we're replacing, which we're leaving alone, and a fixed price covering all materials, labour, testing, certification and Part P notification. No hourly billing, no surprise extras — the price quoted is the price paid.
First Fix Cable Work
We isolate only the affected circuits. The rest of the property stays powered. New cable is routed through floor voids, lofts and existing chases wherever possible to minimise plaster damage. Backboxes are installed and we clean up daily.
Second Fix & Accessories
Sockets, switches and accessories are installed. Circuits are connected to the existing consumer unit on RCBO ways where capacity allows, or we quote a board upgrade if needed. Any plaster making-good is patched with bonding ready for your decorator.
Testing & Re-Certification
Full electrical testing on the new work — insulation resistance, earth fault loop impedance, RCD trip times. We issue a Minor Works Certificate or full Electrical Installation Certificate for the rewired circuits, plus an updated EICR for the whole installation if requested.
Building Control Notification
All notifiable work is registered with Building Control under Part P at no extra cost. You receive your certificate, full test results and Building Control notification — everything a mortgage lender, conveyancer or letting agent will ask for.

Victorian & Edwardian Properties
📍 Southgate, Palmers Green, Winchmore Hill, Wood Green, Crouch End
Mix of original cloth-covered cable, 1980s partial rewires, and modern sections from kitchen and bathroom updates. Often the oldest cable is on lighting circuits hidden behind cornicing — tested fine for years but failing now.
Targeted lighting and bathroom partial — replace only the legacy circuits, reuse the modern sections. Cable routed through floor voids and chimney breasts to preserve cornicing. New RCBO consumer unit only if existing board can't accept new ways.
1930s–1970s Semis & Terraces
📍 Bounds Green, New Southgate, Arnos Grove, Oakwood, Cockfosters
Most failed on EICR with C2 codes on the kitchen ring and shared bathroom/cooker circuits. Undersized cable for modern induction hobs. Supplementary bonding missing in kitchens and bathrooms where the RCD/main-bonding exemption doesn't apply.
Kitchen + bathroom partial — new dedicated 32A/45A hob supply, separate oven circuit, kitchen ring on RCBO, full bathroom rewire with zone-compliant fittings. Bonding verified throughout. EICR re-issued satisfactory.
1990s–2000s Properties
📍 Edmonton, Tottenham, Wood Green, Enfield Town
Cable is mostly fine, but RCD protection often missing on bathrooms and kitchens. Old plastic consumer units pre-AFDD. Single circuit failures from rodent damage in lofts. Kitchen extensions added without dedicated supplies.
Single-circuit or kitchen-only partial — we don't touch the modern T&E that tested fine. Just replace what's failed, add RCBO protection, and certify. Often a one-day job for £950–£1,500.
Rental Flats & HMOs
📍 Edmonton, Wood Green, Tottenham, Hackney, Walthamstow
Limited consumer unit capacity in older flats. Communal-area earthing on conversions. EICR coded "unsatisfactory" because of two or three specific issues — not the whole installation. Letting agent demanding compliance for tenancy renewal.
EICR-led targeted partial — we work from the schedule of items, replace cable on flagged circuits only, fit RCBO protection where missing, then re-test and re-issue a satisfactory EICR. Quick turnaround for landlords on tenancy deadlines.

Partial Rewiring FAQs for North London Homeowners
Clear answers to the most common questions homeowners and landlords ask about partial rewires, EICR remedials, single-circuit replacement and how to tell if a full rewire is really needed across North London.
For official guidance, visit Electrical Safety First or read the Building Regulations guidance.
How do I know if I need a full rewire or just a partial?
The honest answer is: get an EICR. The report identifies which circuits are unsafe or non-compliant, coded C1, C2 or C3. If only a few circuits are flagged, a partial rewire is the right call — and we'll tell you so even though a full rewire would be more lucrative for us. If most circuits fail, or if the cabling is pre-1970s rubber/lead-sheathed throughout, then a full house rewire is genuinely required. We won't recommend one if a partial will solve it.
Can a partial rewire satisfy a mortgage lender?
Yes — if a surveyor has flagged specific electrical issues, a partial rewire of the affected circuits followed by an updated satisfactory EICR is typically all that's needed. We issue a Minor Works Certificate or full Electrical Installation Certificate for the rewired circuits, plus a fresh EICR for the whole installation. We can liaise with your conveyancer on the specific documentation required.
How much does a partial rewire cost in North London?
Single-circuit partials start from £950. Kitchen-only partials from £1,500. Multi-circuit jobs (half house, ground floor, all bedrooms) typically £1,800–£3,200. Compare that to a full house rewire from £4,500. All prices include materials, labour, testing, certification and Part P notification. For a fuller breakdown see our House Rewire Cost Guide.
How long does a partial rewire take?
A single-circuit rewire typically takes 1–4 hours of focused work, completed in a single day. A kitchen-only partial takes 1–2 days coordinated around your kitchen fitter. A multi-circuit partial (half house, EICR remedials with multiple C2 codes) takes 2–3 days. We give you a realistic timeline at the survey before any work is booked.
Can I live in the property during a partial rewire?
Yes — unlike a full rewire, a partial only affects the circuits being replaced. The rest of the property stays powered throughout. We schedule any planned outages in advance — usually a few hours at most — and almost always restore power the same day. For landlords, tenants can normally remain in occupation throughout.
Can a partial rewire fix a failed EICR?
Yes — this is the most common partial rewire we do. If your EICR has C1 or C2 coded circuits, we work directly from the schedule of items, replace cable and accessories on the flagged circuits only, then re-test and re-issue a satisfactory EICR. C3 codes are recommendations rather than legal requirements; we quote those separately if you want to address them in the same visit. If this is for a house sale and time is tight, see Pre-Sale EICR & Rewiring — same scope, conveyancing-speed turnaround.
Will I need to redecorate after a partial rewire?
Some plaster making-good is normal where new cable has been chased into walls. We minimise this by routing through floor voids, lofts and existing chases wherever possible — on single-circuit jobs we often manage with no plaster damage at all. Where chasing is unavoidable, we patch with bonding plaster ready for your decorator. We don't quote skimming or paint — that's the decorator's trade, not ours.
Can you rewire just one floor of a house?
Yes — a floor-by-floor rewire is one of the most common partial rewire scenarios. We replace all circuits on the target floor, leaving the rest of the installation untouched. It's a popular phased renovation strategy: rewire upstairs while you live downstairs, then swap. Each phase issued with its own Minor Works or Electrical Installation Certificate.
What's the difference between C1, C2, and C3 EICR codes?
C1 means danger present — requires immediate action, often the same day. C2 means potentially dangerous — requires urgent remediation to make the installation satisfactory. C3 is a recommendation, not a legal requirement, so an EICR can still be coded satisfactory with C3 items present. Our partial rewires target C1 and C2 items as priority. C3 items are quoted separately if you'd like them addressed.
Do you provide a certificate after a partial rewire?
Yes — we issue a Minor Works Certificate for single-circuit work or a full Electrical Installation Certificate for multi-circuit partials. All notifiable work is registered with Building Control under Part P at no extra cost. We can also carry out a follow-up EICR for the whole installation at the same visit if your mortgage lender or letting agent requires it.
