Cant recommend this guy enough, Assert Heating Services provided a great service during this difficult time. Ryan was professional and clear about the problem I had with my boiler. He took the time to talk me through and show me where the issue was. I didnt feel harrased, he let me think about replacing the boiler before I called him in to do the job. All in all, great job and I now have hot water again. Highly recommend.

Great Service

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.

Spyros Spyrou
Khalid Fahfouhi

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.

Nasim Belone
Katharine Walker

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
