    Worcester Greenstar 24RI - Burner Seal Replacment

    Got some quotes for a service, one person has said if I haven't had the burner seal replaced for past 5 years, it should be done (& service price goes up by £55). Boiler installed in 2015 - never had the 'seal' replaced? Is it a necessary requirement just as a matter of course?
