Highlights
"Excellent communication from start to finish, they turned up bang on time for quoting the job and then carrying out the work. Very professional, would highly recommend this company. Thank you Jo and team, especially Kieran who did the work."
"We always use the same tradesman Keiron, he knows what he is talking about and doing and we trust him fully. He is very polite and friendly and does a good job. The office staff are fantastic too especially Jo."
"Booking the service on H20’s website was very easy and confirmation of a date and time was received promptly. The engineer arrived exactly at the arranged time, a rare thing these days. He was polite, considerate (removing his shoes) and helpful. I was pleased with the work done."

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check — a layer of accountability an unregistered trader doesn't offer. Around 16 years on the register also points to an established business rather than a brand-new one.

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.
