If we find a significant level of lead in your water supply, we will replace the lead parts of the pipe that belong to us, free of charge.
Even when lead pipes are present, the levels of lead in drinking water are normally low. However if you suspect that your home has lead pipes, you can ask us to test the water from the cold kitchen tap within your home through our Lead Pipe Replacement Scheme. As part of the replacement scheme, if elevated levels of lead are found in the pipes, we ask that you commit to replacing the lead pipework within your property boundary. We will replace any pipe that belongs to us.
If you are thinking about replacing your part of a lead supply pipe, please download the following application form and send it to us at:

We will take a sample of the water first to see whether the levels of lead in your water supply are a cause for concern.
If you do not have access to a printer, please call us to arrange for an application form to be posted to you. Our lines are open 24 hours a day.
The level of lead detected in the sample taken from your home will determine whether you are eligible for the free replacement of our lead communication pipe through our Lead Pipe Replacement Scheme. If the lead level detected is greater than the future 10 micrograms per litre (ug/l) lead standard we shall replace the communications pipe (our responsibility) to your property. We would recommend that you check and replace your lead pipework if required to ensure all lead is removed from the water supply.
|Lead sample results||Outcome|
less than the future lead standard
|You will not qualify for the free replacement of our lead communication pipe. You may still ask us to replace our lead communication pipe but the property owner will be required to pay for this. You can also replace your lead supply pipe/internal plumbing if you wish.|
greater than the future lead standard
|You will qualify for the free replacement of our lead communication. We recommend that you replace your lead pipework to ensure all lead is removed from the water supply.|
If you qualify under our lead pipe replacement scheme and you are on a shared supply pipe, you have two options:
1. Arrange with your neighbours to jointly replace the whole length of lead shared supply pipe. We will then replace the lead communication pipe.
2. If your neighbours do not want to contribute towards the replacement of the shared supply pipe, you can lay a new single supply pipe from your property to the point where the old lead supply pipe joins our communication pipe. This may involve crossing your neighbours property, and if so, you will need to obtain their agreement first. We will then replace the lead communication pipe and join to your new pipe.
