A genuine service includes flue gas analysis, a check of the seals and heat exchanger, gas pressure and rate readings, condensate and safety device testing, and a visual inspection of the whole system.
You should also get your radiators and controls looked over, so a fault isn't diagnosed twice, and a written report by email recording the readings and any advisories.
Keeping the paperwork matters for warranties and, for landlords, for compliance. JGH issues certificates and reports promptly, usually the same day.
Book servicing at the same time each year and it stops being a job you remember in the first cold week of winter.

Call and describe it, you'll get a straight answer, not a sales pitch.
