Wiring has a working life. Much of the housing stock around Harrow, Ealing and Watford was wired or last rewired decades ago, and installations from the 1960s and earlier are now well past the point where they can be relied on. Rubber-insulated cable turns brittle, lead sheathing corrodes, and old fuse boxes offer none of the fault protection a modern home needs. A rewire replaces the cabling and accessories throughout, rather than patching a system that has already failed once.
Not every property needs the full job. Where a consumer unit and ground floor circuits were updated in the last twenty years but the upstairs lighting is still on original cable, a partial rewire deals with the failing section and leaves sound work in place. Our electricians test first, then tell you which of the two you are actually looking at.
This page sits under our electrical services. If the fault turns out to be something else, the same engineer can usually deal with it, because Home Utility covers heating, plumbing, electrical and appliance work under one roof.
Signs your property is due a rewire
- Round-pin sockets, or a wooden-backed fuse box with rewireable fuse carriers.
- Black rubber or fabric-covered cable visible in the loft or under floorboards.
- Sockets that feel warm, or scorch marks around plugs and switch plates.
- Repeated fuse blowing on lighting circuits with no faulty lamp to blame.
- Two or three sockets per room, with extension leads doing the rest.
- A condition report returning multiple C2 codes against the fixed wiring itself.
What a house rewiring job with Home Utility covers
- Initial testing to establish circuit condition, earthing arrangement and main bonding.
- Lifting floors and chasing walls to run new cable to each point.
- A new consumer unit with RCBO or RCD protection and surge device.
- Fresh circuits for sockets, lighting, cooker, shower and outbuildings as required.
- Protective bonding to the incoming gas and water services checked and upgraded.
- Full inspection, testing and an Electrical Installation Certificate on completion.
From your first call to the finished job
-
Survey and quotation
An electrician walks the property, tests the existing installation and agrees the position of every socket, switch and light with you. You receive a written quote before anything is committed.
-
First fix
Floors come up, chases are cut and the new cabling is run back to the board. Old cable is removed where access allows. Power is kept on to key areas wherever practical.
-
Second fix and board change
Accessories go on, the consumer unit is swapped and every circuit is connected, identified and labelled. Chases are made good ready for the decorator, and floors are relaid.
-
Test, certify and notify
The installation is inspected and tested against BS 7671, certificates are issued, and the notifiable work is registered with building control so your paperwork is in order for any future sale.
Old cable, BS 7671 and what makes this work notifiable
The clearest evidence that a property needs new wiring is the cable itself. Vulcanised rubber insulation, used widely until the early 1960s, goes hard and crumbles when disturbed, exposing conductors inside ceiling roses and switch drops. Lead-sheathed and cotton-braided cable is older still. Even early PVC has limits: many pre-1970 installations have no circuit protective conductor on the lighting, so there is no earth at the switch or the fitting. Colour dates an installation too. Red and black cores indicate wiring put in before the change to harmonised brown and blue, which became mandatory in the mid-2000s.
Fixed wiring work in England and Wales is assessed against BS 7671, the IET Wiring Regulations, currently the 18th Edition as amended. Under Part P of the Building Regulations, installing new circuits and replacing a consumer unit are notifiable, as is certain work in bathrooms and other special locations. Notifiable work must either be registered with your local authority building control or carried out and certified by an installer belonging to a competent person scheme.
Be realistic about disruption. A full rewire means floors up and walls chased, and the property is far easier to live around if a room-by-room programme is agreed at the outset rather than improvised.
Where the line sits between you and an engineer
Switch off at the socket and unplug anything that sparks, buzzes or smells hot, then leave it alone. Do not open a consumer unit, fit a fuse carrier of a higher rating, or extend a circuit yourself. Fixed wiring is notifiable work under Part P and must be carried out and certified by a qualified electrician working to BS 7671.

Frequently asked questions
How long does a rewire take?
For a three bedroom terrace, plan on the work running across several days rather than one visit, split into first fix, second fix and testing. Access is the main variable. Solid floors, fitted kitchens and boarded lofts all slow cable runs down. An occupied property takes longer than an empty one, because circuits are staged so that some power stays on each evening.
What decides the cost?
Every property prices differently, so we quote after inspecting the installation. The main drivers are the number of circuits and accessory points, whether floors are timber or concrete, how much old cable can be withdrawn instead of abandoned, the condition of the earthing and bonding, and whether you want plaster and decoration made good afterwards. You receive a clear written quote before work starts.
Can we stay in the property while it is done?
Most households do, though it is not comfortable. Furniture has to move room by room, carpets come up in the areas being worked on, and chasing makes dust. We work through the house in sections so the kitchen and at least one socket circuit stay live overnight. An empty property is quicker to work in if you have that option.
Do I need a full or a partial rewire?
Testing answers that, not guesswork. If insulation resistance readings are low across every circuit and the cable is rubber or lead sheathed, the whole installation goes. If only the lighting is original and the socket circuits were replaced in the last two decades, partial house rewiring is the sensible route. We give you the readings and explain what they mean before you decide.
What credentials do your engineers hold?
Engineers are qualified and certified for the work they attend, insured, and background checked before they join the team. Gas work is carried out under the company Gas Safe registration, number 974833. The business is a vetted TrustATrader member, TT32961, where its trade insurance is independently recorded.
Will I know the cost before you start?
Yes. The engineer explains the fault, sets out what needs doing and gives you a price before any work is carried out. If a diagnosis has to happen first, that is explained separately. Nothing gets added once the job is finished, and you are free to decline and pay nothing further.
