How long does a three-bedroom house rewire take?
A three-bedroom house rewire is usually measured in days rather than hours. The exact timescale depends on access to the wiring, the condition of the existing installation and how much making good the property needs afterwards.
The survey is what turns a broad timescale into a workable programme. We inspect the existing installation, trace likely cable routes and check access to the loft, floors, walls and consumer unit before confirming how the work will be organised.
A rewire is normally completed in stages:
- Preparation: We agree which rooms are included, identify circuits that need replacing and protect floors, furniture and fixed fittings where possible.
- First fix: We remove or isolate redundant wiring, install new cables and fit back boxes for sockets, switches and other points.
- Consumer unit work: We connect the new circuits to a suitable consumer unit and check that the earthing and bonding arrangements are adequate.
- Second fix: We fit the agreed sockets, switches, light fittings and other accessories.
- Testing: We test each circuit, investigate any fault readings and complete the relevant electrical certification before the installation is handed back.
The number of rooms is only one part of the programme. A house with accessible floor voids and a clear loft can be simpler to cable than a smaller property with solid floors, finished walls or limited access. We also allow for the time needed to disconnect and reconnect existing circuits safely rather than treating the work as a straightforward cable replacement.
An occupied house usually needs more planning than an empty one. Furniture may need moving, rooms may need to be cleared in turn and power may be unavailable while particular circuits are being worked on. We discuss the sequence with you beforehand so you know which parts of the house will be affected and when.
Older properties can need additional time for careful cable routes. Solid-wall houses, barn conversions and properties with lath and plaster may not allow cables to be chased in the same way as a modern house. Floorboards may need lifting carefully, and existing routes may not be suitable for the new installation. If a house is listed or has significant original finishes, we agree practical access and the visible finish before work starts.
The specification also affects the programme. Extra sockets, outside supplies, electric showers, cookers, garden buildings, data points and changes to lighting all add work beyond replacing the basic circuits. A consumer unit replacement may be needed as part of the rewire, but its position and the condition of the incoming supply can affect how we plan that stage.
Making good is another point to settle before the start date. Removing old accessories and installing new boxes can leave holes or chases that need filling. The quote should state whether this includes limited electrical making good, plastering, decorating or only leaving the areas ready for a separate finish. The standard agreed here can affect both the end date and how soon each room can be used normally.
We do not treat testing as an optional final check. After the installation is complete, we test continuity, insulation resistance, polarity and protective measures. If a reading identifies a problem, we correct it before issuing the paperwork. That final stage can take longer where the original installation has undocumented alterations or faults that are discovered during the work.
The clearest programme comes from a written quotation following a proper inspection. It should identify the rooms and circuits included, the number and type of accessories, consumer unit work, agreed making good, testing and certification. It should also explain any work that depends on access being available once floors, walls or ceilings are opened.
Our electricians are NICEIC registered, with ECA accreditation supporting the standard of the electrical work. That gives you a documented installation rather than a cable replacement with no clear record of what was tested. Once we have inspected the house and discussed how you use it, we can set out the sequence and the practical disruption in the quotation.
The date the electrical work finishes isn’t always the date the house feels finished. After we fit the accessories and complete testing, plaster repairs or decoration may still need attention before furniture and fittings return. A quotation should separate electrical completion from making-good work, so the timescale reflects what you need done.
If you’re planning around tenants, builders or a move, ask for the programme in those terms: which rooms are affected, when power is isolated, when testing is complete and when each area can be used normally. That turns “several days” into a sequence you can plan around.
