Full and partial rewires, consumer unit upgrades, lighting design, data and EV charging — installed to BS 7671, certified and notified under Part P, and set out alongside the rest of the build.
Age alone doesn't decide it. What matters is the condition of the cable, the earthing arrangement and the protection at the board. An EICR will tell you where you stand before you commit to the expense.
Signs that usually point to a full rewire: rubber or fabric-sheathed cable, a fuse board with rewireable fuses, no RCD protection, no earth at lighting points, or sockets that have been extended repeatedly with spurs off spurs.
A rewire is genuinely disruptive — floors up, walls chased, ceilings opened. That's why it belongs at the start of a refurbishment rather than as a standalone job, and why we'd usually rather do it as part of a wider project than persuade you to do it twice.
Electrical installation work in a dwelling is covered by Part P of the Building Regulations. New circuits, consumer unit replacements, and work in bathrooms and outdoors are notifiable — meaning the work must be either carried out by a registered competent person and self-certified, or inspected by Building Control.
On completion you should receive an Electrical Installation Certificate, a schedule of circuits and test results, and confirmation the work has been notified. If a contractor cannot give you those, the work has not been finished properly, whatever it looks like on the wall.
Keep them. It's the paperwork a buyer's solicitor asks for, and the absence of it is a routine cause of price reductions at the point of sale.
For a typical three or four bedroom house, allow two to four weeks, split roughly evenly between first fix and second fix with plastering in between. It's considerably faster and cheaper in an empty property than an occupied one.
It's much easier if you can. Floors come up, walls are chased and power is intermittent throughout. Where staying is unavoidable we phase it floor by floor and keep working circuits, but it extends the programme.
Get an EICR — an Electrical Installation Condition Report. It inspects and tests the existing installation and reports coded defects. It's the honest way to answer the question, rather than taking a quote from someone who benefits from the answer being yes.
Yes. The main constraint is usually the incoming supply capacity rather than the charger itself — we assess the existing main fuse and load before specifying, and can install load management where the supply won't take a full-rate charger alongside everything else.
Yes — an Electrical Installation Certificate with the full schedule of test results, plus notification under Part P. It's issued as a matter of course, not on request.
What it costs, what consent you need, and what to check before taking a quote.
