Cost guide: plumbers

We round up the average costs for some common plumbing jobs, from fixing taps to fitting toilets.

In this article

We’ve surveyed Which? Trusted Traders¹ to find out how much you might need to pay for common plumbing work around your home.

Many plumbing jobs are charged by the hour, and the final cost will be a combination of time, any parts required, and VAT.

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
  • ease of access to the plumbing
  • whether there are isolation valves, or the system needs draining before work can start
  • how long the job takes (often influenced by the two factors above)
  • the quality of fittings and fixtures that you want to be used
  • whether the plumber is disposing of any waste for you.


Ask plumbers to break down the quotes they provide, so you know what you’re being charged for. It’s a good idea to get more than one quote so you have a better idea of the going rate for your particular requirements.

How to save money when hiring plumbers

One way to reduce costs is to take responsibility for waste disposal.

For smaller jobs, it may be cheaper to take any waste to the recycling centre yourself. Commercial businesses are charged to use the facilities, so if they take away your rubbish, the cost will be added to your bill.
