What affects the price
- Property size and layout: larger or more complex homes need more circuits, cable, fittings, and labour
- Age and condition: older or altered installations can require more investigation and remedial work
- Access: occupied rooms, solid floors, restricted lofts, and difficult cable routes add labour
- Fittings and specification: the number and type of sockets, switches, lights, and protective devices affect materials
- Making good: confirm whether plaster repair and decoration are included or priced separately
- Location: labour and access costs vary across the UK
What’s included
- A survey of the existing installation and an agreed schedule of circuits and points
- New fixed wiring, accessories, and protective equipment stated in the quote
- Inspection, electrical testing, and the appropriate installation certificate
- Building Regulations notification where the chosen compliance route requires it
Good to know
How long does it take? The programme depends on the property size, access, whether it is occupied, and the amount of making good. Ask each electrician for a written sequence covering isolation, first fix, second fix, testing, and reinstatement.
Do I need one? Age alone does not prove that a home needs rewiring. Repeated faults, heat damage, deteriorated cable insulation, missing earthing, or an unsatisfactory inspection can justify further investigation. An Electrical Installation Condition Report can establish the condition before major work is agreed.
Before you book, read how to check an electrician is qualified.
How to pay less
- Compare written quotes against the same schedule of circuits, sockets, switches, lights, and finishes
- Confirm whether the consumer unit, certification, waste removal, and making good are included
- Plan socket, lighting, data, and future charging needs before work starts to avoid later changes
- Where practical, complete rewiring before decorating or moving into the property
