Lead Pipe Replacement

Protecting Your Health with Modern Water Supply Upgrades

Thousands of properties across the UK still rely on outdated lead service pipes, especially homes built before the 1970s. While once considered standard, lead is now known to pose serious health risks when it enters the water supply. At Merciers Moling & Construction, we provide a professional lead pipe replacement service, ensuring your home or business benefits from a safe, modern, and fully compliant water connection.

Why Lead Pipes Are a Risk

Lead can leach into drinking water when it passes through old pipes, especially if water is soft or slightly acidic. Even low levels of exposure can build up in the body over time and cause long-term health problems.

  • Children & Babies – Lead can affect brain development, learning ability, and behaviour.

  • Pregnant Women – Lead exposure increases risks to unborn children, including developmental issues.

  • Adults – Prolonged exposure has been linked to high blood pressure, kidney problems, and other health concerns.

The UK’s Drinking Water Inspectorate and World Health Organization both state that there is no safe level of lead in drinking water. Replacing lead pipes is the only reliable way to eliminate the risk.

Our Replacement Process

  • Site Survey – We assess your property to confirm whether lead service pipes are present.

  • Trenchless Installation – Using moling (trenchless technology), we install new MDPE (medium-density polyethylene) pipes with minimal disruption, avoiding the need for large excavations.

  • Approved Materials – All new pipes are WRAS-approved and designed to last for decades.

  • Testing & Certification – After installation, we pressure-test your system and certify it leak-free and fully compliant with current water regulations.
