Thanks Ryan, for a fantastic job on the boiler conversion for our new house, pre-refurb!

Ryan was recommended to us by a good mutual friend, to check a redundant gas pipe that was randomly sticking out of the ground in what will be our living room area and ensure the gas supply was cut off and sound and then remove the eyesore of a pipe for us.

What I really like about how Ryan works is that he’s efficient, professional and really knows his job, and is a good communicator. He always returned my calls and answered any texts/questions within a short space of time, and this to me took the stress out of the whole process. To top it off he gave me a wholesome price on the boiler conversion and kept me well informed throughout the process.

On time, professional, experienced and excellent communication. All key attributes of a fantastic tradesman! Thank you Ryan, we will see you for our annual service and maintenance and highly recommend you to all our friends and family!

Best Wishes, Nita

Recently used Assert after my usual plumber couldn’t come out quick enough for a burst pipe in one of my properties and am very glad I did. Assert were quick to respond and fixed the issue to a high standard in next to no time. Great service all round. Looks like Assert might be my new port of call for any emergencies.

Ryan from Assert Heating Services arrived at the time promised and carried out the job very professionally and left the place spotless. Would recommend Ryan and his company for prompt and professional services without compromise. I have booked Ryan for annual boiler service which will be carried out this week.

Ryan did a great job replacing my two old boilers, re-piping and installing an new eco Vaillant boiler. Arrived on time and all work completed in one day.

We had a new boiler installed and our old radiators upgraded, the plumbing engineers came on time and everything was very well managed. We are so impressed with the quality of the work and recommend Assert Heating Services highly.

Thank you so much for the great service, the attention to detail really made the work stand out from the rest and I look forward to using Assert Heating for any future heating related work.

Our boiler is not as new as other makes but your team provided an excellent service. Assert Heating Services reassured me that they could take on any kind of heating system problems, and they didn’t disappoint. Great work, many thanks.

Having been recommended by a friend, we had no hesitation in asking Assert Heating Services to install a new boiler and central heating system for us. The two engineers that came carried out the work to a very high standard and we are delighted with the results.
