  • Annual Boiler Service and Programmer Replacement

    10Verified Review

    As always, easy to book a convenient appointment for the annual boiler service. Programmer went wrong just prior to visit and we informed Engineer during visit, he confirmed that Programmer was faulty and arranged timely replacement. We've used John Williams Heating Services for over 10 years, including major boiler renewal work and always receive the best possible service. Seen the company grow in that time, standard of service remains high, and we've no plans on using anyone else in the future.
