25+ years experience across Northamptonshire
I have been doing this for 25+ years, a chunk of it as a British Gas engineer, and I have seen most of what a heating system can do wrong. That means the fault usually gets found the first time rather than the third. Every job is Gas Safe registered, priced up front, and left clean. If something is not worth fixing I will tell you that instead of selling you a repair.

“A S Plumbing and Heating recently completed a full boiler, plumbing, and radiator installation in our house, and we couldn't be happier with the results. He was reliable, punctual, and extremely neat throughout the whole process. The heating system works perfectly, and his work ethic and attention to detail are top-notch. Highly recommended to anyone looking for a trustworthy plumbing and heating professional!”
“A S Plumbing installed a new combi boiler a few years ago. The work was done quickly and efficiently. Never had any issues with this boiler and Ali comes back every year to service it. Happy customer!”
“Ali came last year to install a new gas boiler and when messaged a year later to do a service, he quickly responded to confirm he would come and do this. Both visits have been fantastic - great guy and very efficient. Would highly recommend”
