Customer Testimonials

Satisfied Customers in London

See what our satisfied customers have to say about our boiler servicing and how we’ve helped homeowners in London with their boilers.

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!

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.

Arms Djemal

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!

Highly recommend Assert Heating Services

Came round on Monday and diagnosed the issue – we needed a new boiler, which we already knew as it had been knackered for a while. Ryan came back on Weds to replace and did a great job. Highly recommend.

Antony Berou

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.

Sean McAvoy

Very professional and fixed the issue with minimum fuss.

Bishu Debroy

Assert Heating provided a very professional service, very clean and tidy i would recommend them 100%

Ahmet Djemal

Thank you to Ryan at Assert Heating, he completed boiler service but noticed we had an issue with a leaking tap which we were waiting for a plumber to come and fix in a few days time but Ryan offered to cap it for us to save us money on our water bill. I would definitely use again and recommend.

Anthony Arbon

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.

Karen Brant

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!
