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.

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.
New boiler in Hornchurch We have used Gasking a couple of times now and both times they have really impressed. We just had a new boiler installed and we was really happy with the work quality and the price. Tracey and Joanne were really helpfull and Jim fitted to boiler to a really high standard and he even tided up after himself unlike some others. Definitely try these guys. Rob (Hornchurch)
I would highly recomend GasKing to anyone. They do sterling work, and are also very friendly & helpful in more ways than one! Jamie Harvey is a very clever talented man, and I cannot praise him enough for the work he has done in my flat Today! I promise you that you will not be dissapointed!
Jamie moved the boiler from my sons bedroom to the kitchen on the coldest day of the year! even though the job did not go to plan on the day, he came back and sorted it out. I found him very competent as my heating had an ongoing problem for the last two years, I highly recommend Jamie and his team.
Jamie is a magician. After our boiler insurance company wrote off our boiler (just days after a service where the engineer said it was in great condition), I asked for a second opinion and they contacted Jamie from Gas King. Thank goodness I did! He arrived the next day and in under an hour he had diagnosed the problem, sorted it out and saved us the hassle and costs of a new boiler, when all it needed was a more thorough detailed check. Since then he has carried out a soft flush for us, and fixed other issues with our central heating system. His knowledge of boilers is brilliant and he brings confidence and methodology to his work. Very highly recommended.
Great service from Gas King
Turned up on time, fixed the problem. Perfect.
Really prompt service. Good communication re appt time and updates for when they are on their way. Great service.
The engineer that came to our house was polite, knew his job inside out, and completed the job on our boiler very quickly. Would have no hesitation in recommending Gasking to friends and neighbours.
Jamie attempted to repair our boiler, which in the end turned out to be uneconomical. Install of the new boiler was organised and carried out within a couple of days. On each visit I was given a time slot, e-mailed confirmation on the day, from the office, and had a call from the engineer when leaving his previous job. Easy to do but do many others just leave you wondering when or if they will arrive. Adam in the office was organised and helpful. This is a small business on the up
Gasking were absolutely brilliant, couldn’t be more helpful when a problem was detected and showed great concern in making sure everything was safe when we realised there was a gas leak. Very friendly and helpful on the phone before job was even started which gave a lot of confidence when meeting for the first time. When speaking with your repair in future I will be asking for gasking to come and do anything to do with my plumbing issues. Thanks to Adam and jaimie from gasking it was great to meet you.
