What customers say

Based on genuine customer reviews

Projects involving faulty boilers, unvented hot water systems and ageing heating equipment run through the feedback for this gas and central heating specialist. Tariq is named time and again as the engineer who attends promptly, diagnoses accurately and sets out faults and remedies in plain terms, whether the problem is a leak on an unvented cylinder or a breakdown that had left a property without heating or hot water. More than one customer describes his professionalism, patience and depth of knowledge, noting that he restored an almost twenty-year-old megaflo to quiet running and recharged an expansion vessel instead of proposing unnecessary replacement parts.

Yassin also draws frequent praise, both for the office communication and swift booking that precede a visit and for installations, including a full replacement of a Vaillant boiler, motorised valves and expansion tank finished within a single day where other firms had forecast several days and considerable disruption. One thing mentioned again and again is punctual arrival with a courtesy call ahead, tidy workmanship, fair pricing and clear advice at handover. The company covers boiler servicing, gas installation and central heating work, and customers describe calling the same engineers back for further plumbing problems.

Tariq did a really great job on diagnosing and fixing the sensor issue in our boiler at very short notice, as well as fixing some additional issues. Clear communication and a very fair price. Highly recommended.

Just had our unvented boiler serviced today by Tariq from Kewgas. Fantastic service! Communication beforehand from the office was excellent and I got a call to let me know he was on his way. All dealt with really professionally. Would definitely recommend!

Tariq was absolutely outstanding today. My boiler broke down on Easter Monday, and within just 30 minutes of calling, he was at my house the same evening ready to help. His speed and efficiency were incredibly impressive, and he handled everything seamlessly. He was kind and professional throughout, with clear and reassuring communication. He made the situation much easier to deal with and got everything sorted quickly. Great service all around, highly recommended!

Highly recommended, good, dependable service. I’ve been using Yassin’s boiler and gas services for several years now. He’s always efficient, punctual and flexible when I need to move the appointment.

We've used Kew Gas several times and I'm confident to recommend them. Tariq came to an emergency call-out this evening and got my 12 year old boiler going against all the odds! Great service from a charming young man. Thank you 😊

Kew Gas provided excellent service, can't recommend Yassin enough. He did a complete replacement of boiler, motorised valves, expansion tank, et al. He identified numerous issues with the prior installation. Honest, fair pricing, reliable. Would not call any other gas heating engineer.
