Who is responsible for replacing the lead pipes in my property?

The water supply regulations* set strict lead standards for customers’ drinking water supplies. The maximum concentration allowed is 10 micrograms per litre, the same as one part in 100 million.

Many water suppliers already have programmes in place to replace any lead pipes they find on their own network.

However, homeowners and businesses are responsible for all pipes on their property – including internal pipes and the underground supply pipe which connects your home or business to the public water main.

If you’re replacing pipes within your boundary, make sure you contact your local water company, as they may be able to also replace the pipes beyond your house and garden.

WaterSafe and water companies advise replacing all lead pipes with new copper or plastic pipes which have been approved for use with drinking water. A WaterSafe approved plumber is qualified to safely replace lead pipes in line with the  Water Fittings Regulations and Byelaws which protect public drinking water in the UK.
