Quick efficient response
Customer Service
Melvin from Gaswise quickly responded to my call regarding a faulty boiler. He identified the problem, ordered the part and fitted it the next day. I'm very happy with the prompt efficient service I received and wouldn't hesitate to recommend Gaswise to family and friends.

Boiler repair
Customer Service
Rang Gaswise at 8.30 in the morning about my broken boiler (No heating or hot water on a very cold day) and had someone visit at 12. The problem was quickly found (fan needed replacing) he went out to get one, and returned the same day to fit it. Great fast, efficient service, and a nice, friendly bloke! Will definitely use Gaswise UK in future

Once again Melvin came to our assistance
Customer Service
We use gaswise uk to service our boiler every year and wouldn’t go anywhere else. Since getting their number from a work mate we’ve never looked back. Melvin goes through the whole job with you and explains why and what he’s doing. Polite and friendly service id recommend to anyone.

Straightforward, knowledgeable and sensibly priced
Customer Service
Having had our combi boiler serviced earlier in the year and been impressed by the courteous and non-nonsense manner in which Melvin did the job, he was a 'natural' first call when we found the boiler leaking on the first real 'winter test' driving the radiators. He arrived quickly to diagnose the problem, re-assured us that we could continue to use the boiler, and fitted the new parts a few days later which completely fixed the problem. A pleasure to do business with. Thanks Melvin! Peter & Amy

Excellent quality -friendly -professional service
Customer Service
Gaswise recently serviced my boiler they took time out to explain what they were doing and answered any questions I had, overall this was a stress-free experience and it didn't break the bank I would highly recommend Gaswise I have used these guys before a few years ago when my old boiler broke down I used their emergency call out but I never left any review. Middle of winter no boiler. No problem one phone call and it was sorted

Is this a good service
Customer Service
Had a leaking tap in the kitchen, contacted Melvin. Prompt visit to assess problem. Advised new tap needed and asked me to buy one and he would fit next day. Purchased the tap and Melvin came next day to fit. He needed to remove the sink in order to fit new tap but had no mastic or mastic gun to finish job so I had to provided this. Thought plumber would have this equipment. It seemed small emergency jobs are not really his portfolio and I would suggest only use him for larger projects etc. My brother does plumbing and kitchen fitting in Cornwall, wish he lived a bit nearer and says, he should have had all the necessary materials and also looks like he fitted the tap the wrong way round. However, it works so should not complain too much.
Prompt and courteous service, with sound advice offered.
Customer Service
Had a hot water problem, called Melvin and he was busy but called me back within 15 mins. I booked an appointment and was given an idea of costs. He kept me updated of an unexpected delay in his arrival time and then he arrived promptly on the planned time. He got straight down to fixing the boiler snag and in no time the fault was identified and rectified. We have hot water again and the boiler was serviced and good for another year. He also advised me of a potential solution, should my boiler develop a further fault, which would save me having to rush out to buy another boiler. The repair and service cost was fair and the customer service excellent. Thanks again I shall be in touch if any more gremlins appear in my heating system and I have no hesitation in recommending you to my friends.
Melvin to the rescue!
Customer Service
Huge anxiety relieved and trust restored along with hot water! Melvin knows his trade and is completely professional and honest. The fault on my boiler was very small and he fixed it and only charged me the call out fee which is about £30 less then British Gas. They say knowledge is power but he didn't use this to make money out of me by pretending there was more things wrong. He made everything simple and uncomplicated. He arrived the next day after my call for a horrible situation with no heating or hot water which was making my arthritis worse. Phew! What a huge enormous relief! Thanks Melvin, please don't retire or leave the country!
Deserves his 5 Stars.
Customer Service
Melvin (Gaswise UK) is an 'Old School' trader: He turns up on time, he explains what needs doing in a straight-forward manner, he does the work in an efficient and tidy way and he charges you a fair price. What more could you want? Well, he's in my phone-book of Trusted Traders anyway. Thanks Melvin.
