Ed was brilliant, our boiler broke and he fitted a new one the same day which was amazing, worked unti late on a Friday night to get us sorted. Talked us through the options and helped us choose the right one. Can't thank him enough.

Ed was the first person to enter our house since lockdown so we were a little nervous but he put our fears at rest by complying with all the required standards. He did a great job at incredible speed (does this man ever rest or eat?!). The price was good, the service professional. We couldn't have asked for more. Thank you!

Had a love hate relationship with my old boiler - it loved to break and I hated it. Got someone to give me a quote last year and never got back to me. It managed to limp through another winter and needed changing this year. Took the plunge again and phoned AJS plumbing this time. Best decision ever..... Ed is a lovely bloke and came out quickly to give have a look, written quote emailed within hours and booked in really quick. Turned up on the day early doors and worked like a machine - old boiler off, new super efficient boiler in with all new pipe work, new flue, smart controls, and tidied up

Ed gave us a competitive quote and completed the job earlier than expected. He worked tirelessly and we are so pleased with the result. Would recommend to anybody as couldnt ask for better.

Came and replaced a part of boiler but hot water hasn't worked since. Said he would come back to take a look and never has and stopped responding to emails. I'm left to find and pay for a second engineer to come out and properly fix the boiler. Really disappointed and won't use again or recommend to others.

Ed installed a new boiler for us in half a day, including a power flush, balancing the system and fitting a new magna-filter and condensate pipe. Gave us a competitive price, was very efficient, knows his stuff and is a genuine nice guy. Would definitely have him again.
