Rewiring a house is a major job and will require the services of a skilled electrician.

Over the last decade or so, rules and regulations have altered, so the older your property is the more chance of the existing wiring not meeting the current Part P Building Regulations Electrical Safety Rule. In fact, if your existing wiring is 25-30 years old and hasn’t been upgraded it’s time to call in an electrician.

The cost to rewire a house will be determined by the type of property to be rewired, and if the property is old than a house rewire could be an urgent safety matter.

Rewiring a house is a big job. It involves removing all of the old wires and fittings, and installing new wiring and fittings. With the amount of work involved it can take anything from 5 to 15 days depending on the size of the property being rewired. Don’t forget to take into consideration extras, for example if the price includes moving furniture and re-plastering. Always get three quotes for the job and make sure it includes a detailed breakdown of what’s included in the price.

Aside from taking into consideration the size of the property, the cost of a house rewire will also be determined by the condition of existing electrics. It’s an extensive project and one that requires the services of an experienced qualified electrician. Rewiring your house should only ever be done by a trained, qualified electrician who is registered with a competent person scheme, such as NAPIT or NICEIC.

  • Are your light switches round and do you have older round pin sockets?

  • Are there wall mounted light switches in the bathroom?
