Water Supply Pipe Renewals

The supply pipe is the buried pipe that carries water from the company stop valve at your boundary into the house — and it's yours to maintain. Old supply pipes in galvanised steel, iron or early plastic corrode, scale up internally and eventually leak.

Renewal replaces the whole run with modern blue MDPE, restoring pressure and cutting the risk of underground leaks that can quietly add hundreds to a metered bill.

What the work involves

• A new MDPE pipe from boundary to internal stop tap
• Moled (trenchless) installation wherever practical
• Pressure test, disinfection where required, and reinstatement

When you need it

• Persistent low pressure that isn't the water company's side
• A history of leaks or visible corrosion at the internal stop tap
• A metered bill that's crept up without explanation
• Pre-empting failure during landscaping or an extension

Water Supply Pipe Renewals — common questions

How long does a renewal take?

Most domestic renewals are completed in a day, including moling and connections. Long or awkward runs can take two.

Renewal or repair — which is right?

If a pipe has failed once through age, further failures usually follow. Repair suits a single accidental strike; renewal suits corrosion and repeated leaks.

What size pipe will I get?

Typically 25mm MDPE for a standard home — an upgrade on many older supplies, which improves flow to showers and combi boilers.
