Positive: Punctuality, Quality, Responsiveness, Value
Had my new boiler fitted with these guys and very impressed. All my questions were answered with a high level of knowledge for the trade. My new boiler is leaps and bounds ahead of the old one and keeping us all nice and warm on the cold nights. Would highly recommend thanks so much guys

Fantastic service from a quick response in an emergency situation, honest advice to a quick installation of the new boiler. Everything was completed on time and I was talked through every aspect of the job so I understood what was happening and when. Brilliant gentlemen, very helpful and friendly- completely put me at ease in a daunting situation with their knowledge and approachable manner. The standard of work was great and I would highly recommend this company.

We were very fortunate to have found I.S Plumbing and Heating when our old boiler packed up during the lockdown. Ian came out and advised on our options. He was subsequently able to fit a new boiler which is so much more efficient and quiet than our old one. He was professional, punctual and delivered a quality and good value service under difficult circumstances. Definitely a five star rating for the service received. Many thanks Ian and we look forward to seeing you again next year for a service. Ian and Karen

I’ve used Ian twice now. Once as an emergency around Christmas time when we lost all heating in our house and the second time just recently when we bought a new house and the boiler was condemned. Both times Ian has answered his phone straight away, he’s come quickly and on the day of phoning. He’s very friendly, talks you through everything he’s doing is always on time and is very reasonable price wise. I couldn’t recommend him highly enough and will use him from now on.

We’ve just had a new boiler and all new radiators throughout our 3 bed flat installed by Ian and his team. Originally pencilled in for 2 days they completed the job in a day! The new boiler is so quiet compared to our old clunky one its amazing. Cant stress how chuffed we are with the quick and efficient service on the day and over the whole process. We would definitely recommend and will probably be in touch in the future with our next job !
Many thanks Ruth and Kev
