I phoned needing an emergency repair to my heating system and booked in a visit on the phone. Ryan was polite, on time and professional. He diagnosed a fault with my boiler and explained how to rectify it and what that would entail. We agreed there and then for the remedial works to be done. Ryan attended again with parts to fix my boiler and had my heating and hot water up and running again in no time. I have already booked another appointment to have my boiler and both gas fires serviced in a few months time. Both happy and relieved, I have finally found a reliable plumbing and heating engineer!

We called Ryan on a recommendation to look at our hot water system which had stopped working. Ryan came as soon as he could and though the problem was a mystery he figured it out quickly and came back the next day with the right parts to fix. He was efficient, courteous and helpful. His price was fair and we will use him again. Thanks Ryan. Ina Norrman

I’ve used Assert a few times now and each time I was impressed with how they conduct themselves before the job, during and after. The most recent experience was with Ryan who quoted me to replace a diverter valve on my very expensive Vailant boiler. Due to how much water was in the boiler which had to be drained, the job took a couple of hours but that had no bearing on the price or the professionalism whilst in my house. I know from experience others would have milked me for more money so I was pleased that again I paid the job quoted for and I definitely got what I paid for. Great experience with Assert and have no hesitation recommending them.

Quality work, honest price and very professional

Top professional service, they saved me and my family when our boiler stopped working, we didn't have to wait long at all for them to come down and sort it, will definitely be using them again, i highly recommended.

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.

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.
Susan Goode

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.
Alice and John McGowan

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.
