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.

Ryan did a routine service of our boiler. He was friendly, chatty and knowledgable. Would use the company again.

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

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.

Lee was super helpful and fast at fixing our heating!

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!

Ryan was very polite and friendly . I would definitely use Assert heating again and due to professionalism. I would recommend them to others in the future.

Great experience with Assert, can’t thank enough!

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.

Our boiler broke down a week ago and Assert were quick to respond especially given the current circumstances. great value and service, cannot thank enough.
Cheers, all the best.

Great experience from Ryan and his team at Assert Heating Services. Showed up on time, were friendly and professional, sorted out my boiler at a reasonable price. Would recommend.

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!

Very professional and fixed the issue with minimum fuss.

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.
