During a routine examination of the heating system in my daughter's newly purchased house Jason found a potentially lethal fault in the installation of the boiler which he was able to correct and make safe. I would always recommend him for plumbing and heating works because of his meticulous approach to the primary safety aspects of his job, as well as his excellent workmanship

Jason sourced and installed a new radiator for our front room in our new house. He offered advice beforehand on the type of radiator that would heat the room effectively for our particular situation. He also sourced and installed thermostatic valves on some of our existing radiators as well as fixing two of them back on to the wall. He also took the time to talk me through aspects of the boiler and our main heating control too. Jason did a great job, was highly informative and was a pleasure to be around. I would definitely recommend him.

The second job Jason carried out for us was tricky because we required him to commission a boiler which he had not himself installed. He inspected the installation and the manufacturer’s manual and required a number of points to be remedied. We arranged for the contractor to carry these out. On further inspection, Jason was still not satisfied and fixed the items himself at a reasonable cost. However he was not satisfied with the gas pressure which was too low for the boiler to operate with optimum efficiency. He called in the National Grid engineer who claimed that the pressure was sufficient for ordinary operation. However Jason insisted that the pressure was still not sufficient. He advised us therefore to register the appliance with the manufacturer and then call in the engineer. We did this and the manufacturers engineer confirmed Jason's diagnosis. National Grid then accepted that the pressure was too low and as a result had to install a completely new supply pipe.

Jason has recently installed a new boiler for me. I would certainly recommend him. He gave a gold star service. He brought forward the date to install my boiler as old one packed up on Boxing Day. Excellent communication at all times which is very important. Great service.

My elderly father collapsed on Christmas Eve pulling a radiator off the wall on top of him. Jason was round within an hour and had fixed the problem within one more. He could not have been more helpful or supportive and we would recommend him thoroughly.

We had a difficult problem with our heating which a number of plumbers or unable to fix or included expensive work which was not required. Jason spent a long-time (without cost) to investigate and think about where the problem lies and how to resolve it before providing a clear quote for the cost of repair. The work was completed as described and our heating is now fully working
