Turk recognised the problem immediately from my description, came to t]at once.He was businesslike and precise, asking short sharp questions to eolicit what info he needed. He then did the job which was only amatter of setting a reset button., and told me how to avoid the problem in future Iknow he will be my first choice if the boiler needs attention again.His behaviour throughout was enough to inspire confidence. I wouldn't have found him without you. workman, so thank you too.
