That was a great job but since then he’s become very technically aware and is at the forefront of the industry. If there’s a tricky job or something where perhaps other advice doesn’t seem right, I’ll always do my best to get Terry to do the job." > — Customer in Greater London (5.0, via Which? Trusted Traders) > "Terry recommended a replacement during a recent annual service for my old combi boiler, which was identified to have been leaking through the heat exchanger. He didn't charge for the annual service and suggested a like-for-like replacement rather than upselling and provided a quote for pretty promptly and was patient in explaining different options for accessories. He was punctual on the day and clearly explained the steps he was going to take. As he was mixing pointing for the external wall he was even kind enough to fix the pointing above my bedroom window. After the installation I found an issue with the filling loop repressuring the boiler excessively. It was unconnected to the installation but Terry followed up on the phone and came out in person to check the issue for me in any case. I am pleased with his dedication to a providing a quality service. Would recommend him if you're after a knowledgeable and reliable tradesman." > — Customer in Greater London (5.0, via Which? Trusted Traders) > "I have being using Terry for over 5 years to regularly service and repair my boiler. Initially, when I moved into my flat I went through a lot of different engineers, who either continually misdiagnosed or kept trying to get more money out of me, that is until I found Terry. He has been able to diagnose and repair my boiler when others have failed. He also charges a much more reasonable price to do so. Recently the boiler (this is an old boiler) has been playing up. So I contacted Terry to come take a look. He talked me through the issue and explained that the work would cost about half what a new boiler would set me back, but as the boiler was getting on and said he could not guarantee that something else would not go wrong. He explained that the new boiler would come with a guarantee. Terry kept in contact with me that day, discussed my options, requirements and various pricing and gave me a quote that afternoon, having had my parents boiler replaced last year, I can say it was very fair. Due to where the old boiler was seated I want the new one is a slightly different location, which involved moving a cupboard. Terry arranged for the cupboard to be taken down and put back up in the new position and because he had taken the time to identify what I wanted, this was all covered by the original quote, no additional/hidden charges. I will continue to use Terry and am happy to recommend him." > — Customer in Greater London (5.0, via Which?
