How Much Does Rewiring a House Cost in London?
House rewiring is one of the most significant electrical investments a London homeowner will make. Understanding what influences the cost helps you plan your project and compare quotations on a like-for-like basis.
What Affects Rewiring Cost?
Every property is different. The main factors that determine the scope and cost of a rewire include:
- Property size — more rooms and circuits mean more cabling, accessories, and labour
- Property age and condition — older properties often have harder-to-access wiring and may need additional remedial work
- Accessibility — solid walls, suspended floors, or limited loft access can increase the time required
- Specification — the number of circuits, consumer unit type, and quality of fittings all influence the final quotation

What's Included in a Rewire?
A full rewire typically includes:
- Removal of old cabling and accessories
- New cabling throughout the property
- New consumer unit with RCD/RCBO protection
- New sockets, switches, and light fittings (client-supplied or quoted separately)
- Testing, certification, and Building Regulations notification
