A lot of London's housing stock is running on wiring that has outlived its design life. Victorian and Edwardian terraces, interwar semis and post-war estates were wired for a few lights and a handful of sockets, and many have had sixty years of piecemeal additions since. If your home still has rubber-insulated (VIR) cable, fabric-covered flex, round-pin sockets or wiring buried in crumbling black insulation, the installation is overdue for replacement.
Rewiring does not always mean everything. A full rewire replaces every circuit, accessory and the consumer unit. A partial rewire targets what is actually worn out, often the original lighting circuits upstairs while newer kitchen and socket circuits stay. We test before we quote, so you rewire what needs rewiring and keep what is genuinely sound.
It is disruptive work and we do not pretend otherwise: floorboards come up and walls need making good afterwards. What we can promise is a clear plan, rooms handed back usable as we go, and a fixed written price before a single floorboard moves.
What's included
Testing and a straight recommendation
We start with an inspection and insulation resistance testing of the existing circuits. If half the installation is sound modern PVC cable, we say so and price a partial rewire instead of pushing a full one.
Quality cable and accessories throughout
New 6242Y twin and earth sized to each circuit, cables run in safe zones or earthed containment as BS 7671 requires, and accessories you choose (white moulded through to brushed metal).
A new consumer unit with RCBO protection
Every full rewire finishes at a new metal consumer unit with individual RCBO protection per circuit and surge protection, so the new wiring gets the protection it deserves.
Making good and clean handover
Chases are filled and floorboards refitted as standard, ready for your decorator. We agree the finish level in the quote so there is no argument later about who fills what.
Full certification
You get an Electrical Installation Certificate covering every new circuit, plus Building Regulations notification, since rewiring is notifiable work under Part P.
How the job runs
- 1
Survey
We walk the property with you, test sample circuits, count what exists and discuss what you want the finished installation to include.
- 2
Fixed written quote
You get an itemised quote: circuits, accessory counts and finishes, consumer unit specification, making good, and a realistic programme. Full rewires in London typically run £4,000 to £8,000 depending on size.
- 3
First fix
Cables are run under floors and chased into walls, back boxes are set, and the new circuits are pulled back to the board position. This is the disruptive phase and works best in empty rooms.
- 4
Second fix
Sockets, switches and light fittings go on, the new consumer unit is fitted and every circuit is terminated and identified.
- 5
Testing and certification
Every circuit is dead and live tested to BS 7671, the results are recorded on the Electrical Installation Certificate, and Building Control is notified.
- 6
Handover
We walk you round the installation, label the board, hand over certificates and leave the place tidy and ready for decoration.
What it costs
Partial rewires start from £1,800, typically covering the worn-out circuits in part of a property. Full rewires in London usually fall between £4,000 for a small flat and £8,000 for a three or four bed house, driven by floor area, ceiling heights, wall construction (chasing solid brick takes longer than dot-and-dab), accessory counts and how occupied the property is during the work.
The quote is fixed and itemised before we start. If we open a floor and find something unforeseeable, such as asbestos pads under old fittings, we stop, show you, and agree any change in writing before continuing. An empty property is always cheaper to rewire than a furnished one, so if you are between tenants or about to move in, that is the moment to do it.
