Signs your home may need a rewire

  • Old rubber, fabric or lead-sheathed cables
  • An old fuse box with rewireable fuses and no RCD protection
  • Scorch marks, warm sockets, a burning smell or lights that flicker
  • Not enough sockets, with extension leads everywhere
  • An EICR that has come back “unsatisfactory”
  • You’re about to renovate, extend or refit a kitchen — the best time to rewire is before the plastering and decorating

What a rewire involves

  1. Survey and written quote. We look at the property, talk through where you want sockets, lighting and switches, and give you a clear scope of work and price.
  2. First fix. New cables are run and back boxes fitted, usually with floorboards lifted and walls chased. This is the disruptive part, so we plan it around you.
  3. Making good. Walls are then plastered — by your plasterer or builder, or we can recommend one.
  4. Second fix. Sockets, switches, lights and a new consumer unit are fitted and connected.
  5. Testing and certification. The whole installation is tested, you receive an Electrical Installation Certificate, and notifiable work is signed off with Building Control.

How long does a rewire take?

It depends on the size of the property, access and whether the house is empty. As a rough guide, a typical three-bedroom house takes around one to two weeks. We’ll give you a realistic timescale with your quote.

It is possible to live in the house during a rewire — we can work room by room and keep power on overnight — but it is quicker and less disruptive if the house is empty or mid-renovation.

Partial rewires

Not every home needs a full rewire. If the wiring is sound in most of the house, we can rewire individual rooms or circuits — for example a kitchen, extension or loft — and upgrade the consumer unit at the same time.

Frequently asked questions

How much does a rewire cost in Cardiff?

It depends on the size of the property, how many sockets and lights you want, and access. We'll visit and give you a fixed written quote so you know exactly what's included before any work starts.

Do I need to move out during a rewire?

Not usually. We can work room by room and keep power on in the evenings. An empty house is quicker, so if you're renovating anyway it's the ideal time.

Will I get a certificate?

Yes. You'll get an Electrical Installation Certificate and notifiable work is signed off with Building Control, which you'll need when you sell the house.

Can you work with my builder or plasterer?

Yes. We regularly work alongside builders and plasterers and fit our first and second fix around their programme.
