And apart from landlords, who pays for a service every year......?

Some new boilers have a 10 year warranty that is conditional on the boiler being serviced every year by an approved fitter.

I have just had fitted two Viessmann boilers with a 10 year warranty. I have a log book for each which is required to be signed each year by a Viessmann approved fitter. It is much like the servicing schedule you get with a car that requires a dealer stamp.

My installer charges £40 for such a service.

Loads of people have servicing contracts with firms like BG.
