Hello. I'm specializing in OIL and GAS boiler repairs. There's no boiler I can't repair. Happy to sort out every (even hopeless) heating installation. If you already had four plumbers looking at the problem , I want to be the 5th one, who will make all working again.

Robert did a great job for us replacing the immersion tank. He replaces the pump as well. As the tank was leaking he did the job the very next day. I would employ him again.
