Many people, organisations like to make false promises and exaggerated claims with regard to extended warranties on their products. Boiler manufacturers are no exception. Failure to pay for an annual service will invalidate any extended warrantee on labour and parts. The manufacturers will, or should have your details when the boiler is commissioned. Personally, I would contact the manufacturers to make sure, that they have received the registration documents and have your boilers make, model, serial number and your contact details on file; just in case! They will not contact you to remind you that the boiler will need an annual service. I wonder why? Hmmm?
I have to pay for, sub-contract, all initial gas safety testing, amendments or alterations to gas pipe routing and final commissioning of boilers to suitably qualified people who I trust implicitly and who, in return are familiar with my standards and working practices. They will also make connections re electrical, external controls, oh I forgot...PRV terminal too. They take full responsibility for the installation. It is illegal for me to take the front cover off the boiler. So, go figure!
It is the customers responsibility to ensure that the boiler is serviced every year. The manufacturers WILL NOT contact you and it is not the commissioning engineers responsibility to do so either.
Landlords will have to, by law, have a gas safe test and certificate issued annually, in order to rent out any property. Commercial businesses having employees or customers on site, also have to have this certification in place by law, in order to open and trade.
A gas safe certificate IS NOT the same as a service. So, why not have the boiler serviced at the same time? You know it makes sense.

Minimum and maximum standards.
Cars over a certain age have to have an MOT test certificate, by law, so why take unnecessary risks with a boiler? C'mon folks, you know it makes sense.
