The annual service has slipped, and you're wondering whether it matters.
What is actually going on
The annual service has slipped, and you're wondering whether it matters.
The realistic causes, in order
Manufacturer guarantees generally require an annual service by a competent person to remain valid Undetected combustion drift, seal deterioration or condensate trap fouling develops quietly between services Landlords have a separate annual gas safety duty, which is a legal check rather than a service
What we test on site
Combustion analysis against the manufacturer's figures Seals, condensate trap, expansion vessel charge and safety device operation System water condition, which is what most often shortens a boiler's life
What you can safely look at with a boiler that has missed its service
- Find your installation paperwork and check the guarantee's service condition
- Note the date on the last service record if you have one
- A gas safety check and a full service are not the same thing. Landlords need the safety check annually; a service is what actually maintains the appliance.
