Last 2 times we've booked a service with them, they've let us down. And when you and try and call or email to chase up why the engineer hasn't turned up, no one picks up the call or responds to emails. We're still waiting to hear back on a boiler service we booked a week ago and heard nothing. If you can't be bothered to do the job, don't book it in. I had to take half a day off work because of this and you're not going to compensate me for that! Appalling customer service

Have used Gasking a few times now and most recently to install a new boiler. A fabulous company to work with. Efficient, polite, friendly, helpful and reasonably priced. Cannot recommend enough. Very big thank you.

We had the privilege to take services from one of the experienced professionals (James Lucas) at Gasking who was very adept at identifying the root-cause of our heating/boiler issue and took just few minutes to resolve this long-standing issue which had been neglected and termed un-solvable by many previous suppliers/contractors. We are very grateful to James for helping us in such an emergency situation. Highly recommend Gasking any boiler/heating related problems.

Gas king carried out a power flush , excellent and effective job thanks

Very quick and efficient service, kept updated by text message regularly, turned up when expected, and James fixed the issue quickly, and was very professional. Would thoroughly recommend.

Been waiting for a boiler repair for 8 days now Via my Domestic and General Insurance policy. And now informed by Gas King it's going to be at least another 6 days. No heating or hot water for over 2 weeks when repair will be complete. Absolute rubbish service.

Excellent service. Engineer arrived on time, carefully services the boiler, even corrected some sloppy entries in the logbook made by our boiler installer, took time to reply to all our questions, left the place clean and tidy. Will use again next year!

Very happy with the new boiler that gasking just installed. Decent price and Nice nice fella that did the job

Jamie the Operative who attended was on time and very efficient. I got a call in advance of arrival and he was right on time as estimated. He sorted the problem within minutes and went the extra mile to give useful advice how to work the maze of getting a good affordable boiler replacement when asked. This company comes highly recommended.

Great personal service from the bookings team and very knowledgeable engineers who quickly diagnose problems where other engineers often seem to keep replacing parts at random until the boiler starts to work. very much recommended.
