What affects the price?
- Property size and number of rooms — more circuits, sockets and lighting points mean more labour and materials.
- Access — a furnished, occupied home is slower to rewire than an empty property.
- Whether plastering and redecoration are included after the wiring.
- Consumer unit (fuse board) upgrade, which is usually part of a rewire.
- Your region — London and the South East are significantly higher than the North.
