Certified Group LTD

The team replaced our boiler within one working day of viewing the job. They also replaced our water tank, thermostats and some pipe work. They arrived exactly when they said and worked 10 to 11 hour days in order to resolve our heating issues. The team were knowledgeable of their trade and were extremely polite. Thank you Aziz, Kebber and Ken.

When our old boiler broke down just before Xmas and I was in deep distress, Aziz and Kem came to our rescue. With a professional, knowledgeable yet friendly and humane attitude they lost no time in getting to work, after having explained to us all that they were going to do. As the works started, more complications were found than previously anticipated; this did not discourage nor delay them and they kept working hard to sort out the unexpected issues, all this trying to keep their initial promise that my family and I would have a warm house for Xmas. They are tidy, hard-working and trustworthy professionals. It was a pleasure to have them in our house! In the end they did a magnificent job and we are so grateful to Aziz and Kem for all the knowledge, professionalism they put in, but also for their human touch. We will be Certified Gas Heating Ltd's clients for life. Highly highly recommended company!

I am extremely pleased with the work done by Certified Gas Heating Ltd. I had a lot of trouble finding what I consider a good & reliable plumbing company at affordable prices. Certified Gas Heating ticks all of the above and went been beyond my expectations. I like the "customer centric" service they provide - they listened to me carefully and really paid attention to my issues and expectations while also guiding me and providing me advises to chose a fit for purpose solutions that was cost effective to me (other companies proposed me much different solutions with much more unnecessary building work). They are highly trained professionals who explain very well their work to the customers so we always know what is going on and why. They are extremely reliable and never missed a call back, Email or an appointment. They have a lot of attention for details and therefore did a very good job in the timeline agreed - they also left (everyday) the house in a very cleaned state ensuring all dust, tools, etc. were removed. Finally they had constant care for us as they were regularly asking is we were happy with the work and if they should change anything - this continued after the work was done too. I could not be more happier and will safely keep the company's details in my record as I would not go with another company / professional if I have another job to get done Well done and best wish of success to Aziz and his team Kind regards J
