Mains water replacement services in the UK: From consultation to certification

Initial consultation

When it’s time to upgrade your water supply, our team at Happy Dog Plumbing makes it easy from the start. Through a simple phone call or email, we’ll guide you through the early steps of water mains pipe replacement. Send us photos of your stop tap or garden area, and we’ll advise if internal pipes or lead piping are involved. We’ll also check if your location qualifies for a replacement scheme.

On-site survey

If further assessment is needed, we’ll carry out a local site visit to review the condition of your underground pipework and pinpoint where the issue lies. We assess everything from drinking water quality to the depth and layout of the existing water supply. Our trained engineers take care to inspect the route that connects your home to the mains, ensuring all replacement work is planned accurately and safely, whether you’re in a city terrace or countryside cottage.

Certification and commissioning

Once your main water line replacement is complete, we fully test the system and ensure everything runs smoothly from the property boundary to the internal connection. You’ll receive a certificate confirming that the pipe installation meets all industry and water board requirements. We’re also happy to assist with paperwork if you’re applying for the lead pipe replacement scheme. Call us when you need urgent help.
