Fantastic work carried out on a tired shower room that was long over due a refit. Dan and the team were professional, friendly with excellent attention to detail nothing was too much trouble. We are thrilled with the final results!!!

We had our boiler serviced by gaswise for the last couple of years and the service has always been great. We had Jake come over this time and he went above and beyond by sorting out a loose tap that he noticed while servicing. It may seem like a small thing but goes to show how he goes above and beyond for his customers. Thanks for your help.

Very diligent company. Installation of two commercial boilers into a large church. Thorough site surveys carried out over three visits including specialist flue manufacturer and the boiler manufacturers. Well managed installation with excellent post installation hand over and follow up.

Jack initially came to service our boiler, he was friendly, professional and did a great job. We wanted our heating system flushed, so asked for a quote. This was sent the same day and our system was flushed through on the day we wanted, all ready for the winter months by Jack & Harry. Again a friendly professional manner, and our home left clean & tidy.

We just moved in to our new property on Friday, we reported the taps not working in the kitchen on Thursday, Ryan came around, identified the problem, and changed the taps. Great, professional service, Ryan was very friendly and professional. Thank you.

Ryan completed a boiler replacement and a Landlords certificate for us on our rental property. He was friendly and efficient, and we really appreciate the effort he went to, to ensure we were happy with the installation and that we understood how to use it before he left. Thanks
