Watermarcs have been responsible for maintaining and testing the gas installations at my rental apartment for the past 10 years. The quality of their service and advice is exemplary. We also use them to maintain and service our domestic installations where the same high quality of service has been consistently delivered for 6 years now.

Marc comes and checks our gas installations on our camper van conversion, always a great job, Top Bloke .

Boiler wasn't working. Was easy to arrange a time for Marc to come round and assess the problem which he identified within 5 mins. He couldn't fix same day due to not having the part, but came back first thing next morning, fit it quickly, and we were back up and running! Very professional, courteous, tidy, responsive and quick. Would recommend!

Chap arrived and said who he was and where he was from. A helpful fella and explained what he was doing and gave the boiler a service. Explained to us what work was needed and suggested different scenarios to correct problem. Clean and tidy job done. Will definitely use your company again and reccomend to others Service: Heating system maintenance

Be wary of Watermarc's claim to be "plumbing experts". Also be warned about their complete lack of customer aftercare. After our old boiler (having been serviced annually by Watermarcs for 7 years) "died" due to flooding caused by a plumbing defect, we asked Watermarcs to supply and install a new boiler. They advised that in order to prevent a re-occurrence of the flooding problem, a new separate outlet should be created for the condensate pipe. They quoted for this extra work, we said "yes", but much to our surprise, and without consulting us, they decided to reconnect to the old shared outlet which had caused the problem with the old boiler. They assured us that they had increased the angle of the fall and and that this should work adequately for the new boiler. They gave a verbal recommendation that we should purchase a particular part which would reduce the risk of future flooding. We repeatedly asked in emails for details of the part in question, but we never received a response. When the new boiler developed a fault, we asked Watermarcs to inspect under the terms of our 12 months warranty with them, but they refused to do so, telling us instead to contact Baxi. This we did, only to discover the the fault was not with the boiler itself, but with the plumbing. Baxi confirmed that the proper solution was the creation of a separate outlet, and any installer should have done this, particularly in the knowledge of how the old boiler had died. We advised Watermarcs, and they blithely told us that they were "happy" with their performance and did not intend to communicate with us any further. We feel very much let down, particularly as we had been a loyal customer of Watermarcs for 7 years. Service: Water heater installation

Fast reliable service, would not hesitate in recommending watermarcs. Very happy to support a local family business. My boiler had a fault and Marc refused to be beaten, it would have been very easy to just say it was dead and needed a new boiler (it does soon, it’s old!) but Marc efficiently troubleshot it and sorted it cost effectively. Trustworthy company not after a quick buck. Service: Heating system maintenance

We have been using Marc for several years now, to maintain our boiler and the occasional call out.

Highly recommended this business. Called for a broken down boiler and they came out same day. Marc did excellent job fixing the problem and also gave me valuable advice moving forward. They were not overly priced and did a great job. I will definitely be using them again for any future jobs. I really can't say anything negative as I couldn't fault them.

Marc serviced my boiler, rebalanced the heating system and got the system optimized and working better than ever. House heated and boiler off before getting out of bed. Perfect. Marc is very professional and knowledgeable. Having moved into a new property with an eclectic heating system, Marc diligently checked the system throughly and determined what might he causing performance issues. He was spot on. Marc is a genuine tradesman who evidently takes pride in what he does. He was honest and interested in addressing the problems with the system. I would recommend him highly for boiler servicing and fault detection and diagnosis with a heating system.
