Been that way since 1998, doubt they’ll change it yet.
You can have a gas safety check and a service (appliance dependant, eg boiler). The former is more like an MOT and the latter is a service as per mi’s.
The manufacturers' instructions stipulate service intervals and their extent.
These should be adhered to but companies like Homeswerve choose their own methods, which fall short and often lead to warranty repair issues when manufacturer is called out.
