Lead water pipe replacement in London

Lead water pipe replacement in Surrey

We specialise in lead water pipe replacement and external water supply upgrades, replacing outdated lead pipework with modern MDPE water supply pipes. Using trenchless underground moling wherever possible, we install new water supply pipes with minimal digging, reduced disruption, and full compliance with current water authority regulations.

Why Lead Water Pipe Replacement Is Important

Many older properties in London still have lead water supply pipes. Over time, these pipes can corrode, restrict water flow, and pose potential health risks.

Replacing a lead pipe can:

• Improve water quality
• Increase water pressure and flow
• Reduce the risk of leaks and pipe failure
• Bring your property in line with current regulations

If your home was built before the 1970s, there is a strong chance it still has a lead water supply pipe.

Trenchless Lead Pipe Replacement Using Underground Moling

In many cases, we can replace lead water supply pipes using trenchless underground moling, avoiding the need for extensive excavation.

Underground moling allows us to:

• Install new pipework beneath driveways, paths, and gardens
• Minimise surface disruption and mess
• Reduce reinstatement costs
• Complete installations faster than traditional digging

This method is ideal for long or difficult pipe runs and is commonly used across residential and commercial properties in London.

Compliance with Water Authority Regulations

All lead pipe replacement work is carried out in accordance with current water authority regulations. We ensure the correct materials, pipe sizing, and installation methods are used to deliver a safe and compliant water supply.

If required, we can also advise on:

• Shared water supply separation
• Boundary responsibilities
• Stop tap relocation or upgrades

Frequently Asked Questions

Do I need to replace my lead water pipe?

While not always legally required, replacing lead pipes is strongly recommended. Lead pipes can affect water quality and are no longer considered suitable for modern water supplies.

Can you replace my lead pipe without digging?

In many cases, yes. We use trenchless underground moling to install new water supply pipes beneath driveways, paths, and gardens with minimal excavation.

How long does lead pipe replacement take?

Most lead pipe replacement projects can be completed within a day, depending on access, pipe length, and ground conditions.

Who is responsible for the lead water supply pipe?

Homeowners are typically responsible for the water supply pipe from the boundary into the property. We can confirm responsibility during inspection.

Will replacing my lead pipe improve water pressure?

Yes. Replacing old lead pipework with modern MDPE pipes often results in improved water pressure and more consistent flow.
