Parents have electric underfloor heading so I am new to gas boilers.
Unit was serviced as part of the sale of the house but has done three years since then and is obviously going to run for more hours in the next three months than the following 9.
Never missed a beat and I don't feel I want to pay for a service/breakdown contract but if should be serviced annually its clearly now over due.
Found the below on another thread, but no mention of how often is advised, or equally what the risks are if you don't.
Its a Main 30HE I think.

Servicing is a very variable procedure based on the boiler model, age and known issues.
If the histroy of your boiler is known it may only require the vessel to be inflated a litttle, fan pressure taken, flue gas analysis taken and a few other basic safety checks.
However a full service (and the way I do them on these Worcesters) would entail...
Bleed all radiators, drop the pressure and check/inflate expansion vessel, re-presurise system
Replace auto air vent if suspect blocked/leaking
Working pressure taken at meter and boiler
Tightness test of boiler gas valve
Remove fan, burner, heat exchanger access cover, electrodes, condensate trap, condensate syphon
Scrape through/brush and jetwash heat exchanger
Wash out sump (and if necessary remove telescopic flue section for access)
Dis-assemble condensate trap and clean
Wash out and check exit hole in syphon
Check fan impeller and burner for debris
Re-assemble with new trap seals, fan outlet seal, bearing plate, burner seal, hex acc. cover seal, electrodes (inc. seal/sight glass etc.)
Check boiler for any water leaks/faults etc
Check flue and condensate run
Run boiler and adjust check combustion high and low
Check disturbed joints with gas sniffer
Measure and calculate gas consumption
Check boiler for previous stored errors
Check ionisation current
Test flame lockout
Re-test flue gas analysis with case on (to further check flue integrity)
Check other gas appliances (visual)
A typical parts cost would be around £75.00 and it's anything from 2 to 3 hours work around £175 total.
