Highlights
"We have been using GR Plumbing for over 10 years to do our annual boiler service and those of some rental properties. Always a pleasure to have Gareth around, excellent service and knowledge."
"GR Plumbing carried out my annual boiler service and replaced a hot water motor. Used them for years, always an excellent service and his time was no different, on time, tidy work and very helpful Thank you"
"Gareth responded to a call at 10am - once connected, he sent me a number of WhatsApp messages which allowed me to diagnose the issue. He was able to get to my flat at 230pm, and the boiler pressure gauge (the problem) was replaced by 3pm. Super fast, super clear on what needed doing next, and very reasonable prices as well. Highly, highly recommended. I'll be calling Gareth for any boiler and plumbing issues I have in future."

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 registerSmart checks
Before you hire a plumber
Agree 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.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
