Alastair , E17
Gas / Heating engineer

I found Assert by chance on Google last year as I needed a gas engineer to connect a gas cooked in a property I rent out. Ryan surpassed all my expectations of a fast and reliable service. He was very professional from the start and charges very fair prices. For this reason, I started calling Ryan whenever I have a problem in any of my properties I rent out and he’s always been very responsive and honest. Highly recommended!

Livia Marotti

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

A very prompt and professional service. Highly recommended. Would definitely use again.

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.

helen georghiou

Ryan came promptly when my boiler had problems and returned to carry out repairs at a mutually convenient time. excellent service

Michael Chrimes

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!

Ryan from Assert Heating Services came yesterday to do a full heating check. He was very knowledgeable and also suggested changing an old radiator to improve heat retention in a cold room. We’ll definitely have Ryan back to fit the new radiator and for future heating checks. I’ve already recommended Assert Heating services to a friend!

Lucy Simler

Ryan came around to replace our old boiler with a new one as it had developed a fault that couldn’t be fixed. From the beginning he explained the issue with the existing one and arranged to fit a new one within 2 days. When installing, again Ryan explained everything we needed to know about the new boiler and also made sure everything was fully up and running before leaving. He also tidied up after himself so it looked like no one had been here! Highly recommended.

Ahmet Djemal

Great experience with Assert, can’t thank enough!

charlotte baird

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.

AndyC-2432

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!

Rebecca C

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
