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.

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.
