I couldn't be more than impressed with Matt and his team. From the start Matt's communication was great. He was quick to respond and kept me informed every step of the way. Not only was the service prompt, the work itself was of very high quality and left everywhere clean and tidy. Overall a great service and experience with Matt. I highly recommend Matt to anyone looking for a plumber and I will definitely be calling on him again next time I need help!
The work carried out by Matt was excellent and to a high standard. I’d highly recommend and will be using again!

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.

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.
