Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Detailed reviews
These are the individual reviews we hold for GWG Watermains, including the highlights above. The 43 headline total is the review volume reported across public review sources.
After finding out there was a leak at an elderly relative's property, we found GWG Watermains via the Water Safe recommended list of companies. As we lived some 50 miles away, we arranged to meet Gareth at the property for a site visit. He explained the process for tracing the leak and sent us a quotation covering what was discussed. He managed to fit us in for the repairs early in the following week. We arranged to meet Gareth on site again and the work was carried out within 5 hours. This included replacing the main feed from the boundary to the house, a new stopcock and plumbing into the existing internal pipework. All the outside areas were made good, with soil/turf put back as before and concreting the small hole in the path by the front door. The work was carried out professionally and we received a Certificate of Compliance to cover the repairs. We were grateful that Gareth made a very stressful situation less so, for being punctual and helpful at every point.
Many thanks to Gareth at GWG who replaced our water main on Monday. It was an urgent job and Gareth was extremely quick to come out and inspect then send a quote. The work was done quickly because they managed to slot us in and the guys made good the holes and disruption so you wouldn’t know they’d been! I would happily recommend GWG and wouldn’t hesitate to have them back. Steve
Punctual, responsive, tidy and professional. Kept me informed throughout the job - would highly recommend

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.
Check the WaterSafe registerAgree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
