What electrical rewires work involves
A rewire replaces the cabling, accessories and consumer unit in a property. A full rewire involves lifting floors and chasing walls, so it is usually done when a property is empty or during a wider renovation.
Rewire cost depends on property size, accessibility and certification needs.

What changes the price
- Number of rooms and floors
- Circuits, accessories and cable runs scale with the size of the property.
- Full or partial rewire
- A partial rewire addresses the worst circuits; a full rewire replaces everything.
- Property age and construction
- Solid walls, lath and plaster and concrete floors all make cable routing harder.
- Number of accessories
- Additional sockets, lighting points and outdoor circuits add materials and labour.
- Making good
- Plastering and decoration after the electrical work is often a separate cost.
- Consumer unit and earthing
- A new board, bonding and earthing upgrades are normally part of the job.

Common questions
Can I live in the house during a rewire?
It is possible but disruptive, and it usually takes longer. Many people arrange it around being away or during other works.
How do I know if I need a rewire?
An electrical installation condition report tells you the real state of the installation. Age alone is not proof either way.
Is making good included?
Often not. Ask explicitly whether plastering and decoration are in the price.
