Great job, quick and efficient
Many thanks to Mark James for a quick response to repair the leak in my hot water tank. I will always be grateful that he came out early on Monday morning to make a temporary repair followed up later in the week by replacing a part on my hot water tank.
Mark was punctual, friendly and professional. The servicing of my boiler was efficient and cost effective. Great job, thank you!
My regular plumbers. Pump for bathroom shower failed. Mark called to check on the pump - new one ordered - delivered next morning - fitted + new pipework all in less than two hours. So usual speedy, efficient service from Mark James Plumbing.
Very pleased with the excellent service carried out on my gas boiler. Also, thank you for checking the cold water tank in the loft as I wanted to know that it wasn't developing any leaks.
Morgan was prompt, efficient, knowledgeable and friendly. Excellent service.

Before you hire a gas engineer
By law, anyone working on your gas appliances must be on the Gas Safe Register — ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
Confirm they cover your area and can actually come out in your timeframe before anything else.
Read recent reviews for reliability and turning up on time — not only the quality of the work.
