We were looking for a new company to service our Viessmann boiler, and happened upon Tom. He has done an excellent and thorough job, doing a far more comprehensive service than previous companies. A proper strip down of the boiler, fully tested, gas supply checked for leaks back at the meter, and thorough clean of our Magnacleanse filter. Very courteous throughout, taking great care to remove his shoes on frequent trips to get tools from his van. Then gave me some good advice on ASHP which I would be keen to progress with him in the near future.
