Cost guide: electricians

Our expert guide to the average cost of some common electrical jobs, from installing a new light to rewiring a house.

In this article

We’ve surveyed Which? Trusted Traders¹ to find out how much you might need to pay for a variety of electrical jobs around your home.

Our figures are only a guide to average costs, and there are several factors that can affect how much you’ll be charged, including:

  • where you live
  • the age and condition of your property
  • how long the job takes
  • whether the electrician is disposing of old appliances for you
  • whether wires need to be hidden in walls (chased).


Ask electricians to break down the quotes they provide, so you know what you’re being charged for. Get at least three quotes to get a better idea of the going rate for your particular requirements.

Find trusted electricians near you. Only electricians who have passed an assessment by our trading standards professionals, and who follow our Code of Conduct, can become Trusted Traders.

**The price can increase if you want wires hidden (chased) in walls, as this takes longer and may require replastering. Surface wiring is cheaper and quicker, but doesn’t look as neat.

***You may also need to employ a plumber to complete the installation.

Costs for rewiring and electrical inspections

Bear in mind that it will take longer to rewire an occupied house than an empty one, which can affect the cost.

Rewiring often takes at least two people. It may be done more quickly with more staff, but costs (total man hours) are likely to be the same.

Unless otherwise specified, prices include labour and materials but exclude VAT.

How to save money when hiring electricians

Many electricians will charge per hour or per day, rather than having a set rate for certain types of jobs.

You may be able to reduce costs by cutting the time they need to spend preparing for the work, for example by moving furniture out of the way before a rewiring job.

Some smaller jobs, such as replacing a light switch, might only take a few minutes. So if you’re paying an hourly rate, grouping a few small jobs together could mean you get better value from your electrician’s visit.
