Recommending Billy as he has just been round to carry out our annual boiler check (required for boiler warranty and advised by Gas Safe despite lockdown). Due to the coronavirus lockdown, he ensured he followed government guidelines. He made sure that he kept to the social distancing rules, kept well back for me to open the door to let him in, he was wearing gloves, a mask and he wiped down all surfaces that he had touched before leaving. I should add that he also installed the new boiler for us last year and we were very happy with the results of that too. Polite, conscientious and tidy.
