A Rewire Done Once, Properly
The electrical installation is the one part of a house that can quietly become dangerous. Cabling degrades, old fuse boards offer none of the protection modern ones do, and decades of added sockets and spurs leave a patchwork that no longer matches how a family uses electricity. A rewire is how you put that right — not a cosmetic job, but the safety-critical backbone of the home, renewed to the current standard and ready for the next thirty years.
This page is for the house rewire, the full and partial rewire, the consumer unit upgrade and the period-property rewire — carried out to the current 18th Edition regulations by qualified electricians. As a design-and-build contractor with directly-employed electricians, we deliver it under one fixed-price contract: the condition report, the new consumer unit and circuits, the sockets, lighting, data and EV provision, the testing and certification, and the making-good afterwards. On its own, or folded into a wider renovation — which is the most efficient time to do it.
A rewire is also the moment to future-proof. With floors up and walls open, adding EV charging, structured data cabling, smart lighting and heating infrastructure, and extra circuits for a kitchen, garden office or heat pump is straightforward and tidy — whereas retro-fitting them later means lifting floors and chasing walls all over again. We design the new installation around how you actually live and how you are likely to live, not just a like-for-like replacement.
What separates a good rewire from a poor one is partly the visible work — tidy chasing, sensible socket positions, a well-labelled board — and partly the invisible: correct cable sizing, proper earthing and bonding, RCBO protection on every circuit, and thorough testing before anything is signed off. These are the things that make the installation genuinely safe, and they are exactly what the certification process exists to verify.
We rewire homes across NW3, NW8, NW1, NW11, N6, W1 and SW London — period houses and flats with ageing installations, properties being renovated, and homes being future-proofed for EV charging and smart-home technology — each tested, certified and notified to Building Control.
Six Kinds of Rewiring Job
From a full strip-out to a targeted upgrade, the right scope depends on the condition of your installation and your plans. These are the six we carry out most.
Full House Rewire
Every cable, the consumer unit, all sockets, switches and fittings replaced and brought to the 18th Edition. The right choice for an old or never-upgraded installation — a clean slate, safe and certified.
Partial Rewire
Renewing the consumer unit and the most worn or non-compliant circuits, while keeping sound wiring in place. Less disruptive and lower cost — appropriate only where the rest of the installation genuinely tests safe.
Consumer Unit Upgrade
Replacing an old fuse board with a modern unit with RCBO protection and surge protection — a significant safety upgrade in itself, where the existing circuits test sound but the board is outdated.
Period Property Rewire
Rewiring a period or listed home with care for cornices, panelling, plaster and original features — routing cables sympathetically, lifting and relaying floors carefully, and minimising chasing into historic fabric.
Flat Rewire
Rewiring a flat or maisonette, coordinated with the building's communal supply and any freeholder or managing-agent requirements — including the licence-to-alter process where a lease requires it.
Rewire With Renovation
The rewire carried out within a wider renovation, when floors are up and walls are open anyway — first fix with the other trades, second fix as rooms are finished. Avoids doing the disruption and making-good twice.
What a House Rewire Actually Includes
A rewire is safety-critical, and the detail matters. Every element below is delivered, tested and certified under one fixed-price agreement.
Condition Report (EICR)
Before we touch anything, an Electrical Installation Condition Report tells you exactly what is unsafe, non-compliant or worn — so the scope is based on the real condition of your wiring, not a sales pitch for a full rewire you may not need.
New Consumer Unit
A modern consumer unit with RCBO protection on every circuit, surge protection and (where recommended) arc-fault detection — clearly labelled, properly rated and the heart of a safe installation.
Circuits & Cabling
New cabling sized correctly for each circuit — lighting, sockets, kitchen, boiler, showers, garden — run safely under floors and within walls, with sensible circuit separation so a fault in one area does not take out the house.
Sockets & Switches
Plenty of sockets where you actually need them — with USB-C and USB-A integrated — in the finish you choose, from white moulded to brushed brass, matt black or polished nickel. No more extension leads trailing across the room.
Lighting Circuits
New lighting circuits with LED-ready dimming, multi-way switching and zoning — and the wiring for a layered, scene-controlled scheme where you want it. Designed around how each room is used, day and night.
Data & Networking
Cat6 structured cabling to key rooms, a central network point and Wi-Fi access points — a reliable wired backbone for home working and streaming, designed in while the walls are open.
EV Charging Supply
A dedicated, properly protected supply for an electric-vehicle charge point — installed now or pre-provisioned for the future — sized so it works alongside the rest of the house load.
Fire & CO Detection
Mains-linked, interlinked smoke and heat alarms and CO detection to BS 5839-6 — the life-safety system that a rewire is the right moment to bring fully up to standard throughout the house.
Smart Home Infrastructure
The cabling and provision for smart lighting, heating and AV — Lutron, Hive, Crestron or Control4 — designed in during the rewire, so the system can be added cleanly without lifting floors again.
Earthing & Bonding
Correct main earthing and protective bonding to gas, water and structural metalwork — the fundamental safety provision that an old installation often lacks, and which a proper rewire always puts right.
Testing & Certification
The whole installation tested, an Electrical Installation Certificate issued, and the work notified to Building Control under Part P — the documents that prove it is safe and compliant, for you, your insurer and a future buyer.
Making Good
Floors relaid, chases filled, walls and ceilings made good and ready for decoration — so the house is left tidy, not riddled with the scars of the rewire.
Six Signs Your House Needs Rewiring
A rewire is not always necessary — but these are the signs that it is, and the reason we always start with a condition report rather than an assumption.
An Old Fuse Board
A board with rewireable (ceramic) fuses or no RCD offers none of the shock and fire protection of a modern consumer unit. One of the clearest signs an installation is overdue.
Old Cabling
Rubber, fabric or lead-sheathed cabling — common in pre-1960s homes — degrades and becomes brittle and unsafe. If you can see it in the loft or under floors, the installation almost certainly needs replacing.
Frequent Trips or Blown Fuses
An installation that repeatedly trips or blows fuses is telling you it cannot cope or has a fault. It is a warning, not an inconvenience to be worked around with a stronger fuse.
Scorch Marks or a Burning Smell
Any discolouration around sockets and switches, or a faint burning smell, indicates overheating — a genuine fire risk that should be assessed urgently.
Too Few Sockets
Extension leads and adaptors everywhere mean the installation was designed for a different era of electrical demand. A rewire designs in the sockets and circuits a modern home actually uses.
Never Upgraded
An installation more than 25–30 years old, or that has never been upgraded, is likely due regardless of symptoms. An EICR confirms the position objectively, so the decision is based on fact.
Eight Stages, From Brief to Handover
A rewire is safety-critical and disruptive, so it rewards a careful, well-sequenced process.
Free Consultation
We discuss your concerns, your plans and your budget — whether the rewire is standalone or part of a renovation. No charge, no obligation.
EICR & Assessment
An Electrical Installation Condition Report establishing exactly what is unsafe or non-compliant — so the scope and price are based on the real condition of your installation.
Circuit & Points Plan
A plan of circuits, socket and switch positions, lighting, data, EV and smart provision — designed around how you live, and agreed with you before any cable is run.
Sequence & Decant Plan
A week-by-week programme, the sequence of rooms, and a plan for keeping essential power on or decanting — so disruption is managed, not a surprise.
Cabling & Back-Boxes
Floors lifted, walls chased, new cabling run and back-boxes set — the bulk of the disruptive work, carried out methodically with the house protected.
Board, Accessories & Test
The new consumer unit, sockets, switches and fittings installed, then the whole installation tested rigorously to BS 7671.
Certification & Handover
The Electrical Installation Certificate issued and the work notified under Part P, floors and walls made good, and a handover walk.
Defects Period & Warranty
A 12-month defects period and a 12-month defects period on the works.
Four Tiers, Honestly Drawn
What a rewire costs depends on the size, the number of points and the level of future-proofing. Here is how our four tiers differ.
Where Your Budget Actually Goes
For a representative full rewire of a 3-bedroom house, here is the honest breakdown of where every pound is spent.
The Standard We Wire To
Every rewire is carried out to the current regulations. Here is what that means in practice.
Regulations & Protection
- Standard: BS 7671:2018 + Amendment 2 (the 18th Edition wiring regulations)
- Consumer unit: RCBO protection per circuit, Type 2 surge protection (SPD)
- AFDDs: Arc-fault detection devices where recommended — e.g. bedroom and lounge circuits
- Earthing: Main earthing and protective bonding to gas, water and structural metalwork
Circuits & Cabling
- Cable: Correctly sized twin-and-earth or singles in conduit, de-rated for installation method
- Separation: Sensible circuit separation so a fault is contained, not whole-house
- Dedicated circuits: Kitchen, cooker, shower, immersion, EV, garden and boiler as required
- Lighting: LED-compatible dimming, multi-way and zoned switching
Future-Ready
- Data: Cat6/Cat6a structured cabling and access points
- EV: Dedicated, protected supply for a 7kW charge point
- Smart: Provision for Lutron, Hive, Crestron or Control4
- Renewables: Provision for heat pump, solar and battery where planned
Testing & Certification
- Testing: Full dead and live testing of the installation to BS 7671
- Certificate: Electrical Installation Certificate (EIC) issued
- Part P: Notified to Building Control by a registered competent person, with a BS 7671 certificate
- Detection: Mains-linked smoke, heat and CO alarms to BS 5839-6
Certification, Part P and Why It Matters
A rewire is only finished when it is tested, certified and notified — the paperwork is not a formality, it is the proof your installation is safe.
Rewiring is notifiable work under Part P of the Building Regulations, which means it must be either signed off by your local Building Control or certified to BS 7671 by a registered competent person. The installation is certified to BS 7671 by a registered competent person, who notifies Building Control on your behalf, so you receive both an Electrical Installation Certificate (EIC) — confirming the work meets BS 7671 — and the Building Regulations compliance certificate, without you having to arrange or pay for separate inspections.
These documents matter well beyond the day the work is done. Your home insurer may ask for evidence that electrical work was done by a registered electrician; a mortgage lender's surveyor will look for it; and when you sell, the buyer's solicitor will request the certificates. A rewire without them — done by an uncertified electrician or DIY — is a problem that surfaces at exactly the wrong moment and can hold up a sale or an insurance claim.
We also issue an Electrical Installation Condition Report (EICR) as a standalone service, whether or not you go on to rewire — useful for landlords (who are legally required to have one every five years), buyers doing due diligence, and anyone who simply wants to know the true condition of their wiring.
