Ryan and Paul did a fantastic job installing a new boiler under pretty difficult conditions. Thank you for being so professional and leaving the flat clean and tidy. Wouldn’t hesitate to recommend you

Great experience with Assert, can’t thank enough!

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!

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 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.

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!
