Yes. You should make sure your Combi Boiler is serviced every year. As well as keeping your boiler running at maximum efficiency, an annual service is also a condition of the warranty for many new boilers. If you want to keep your boiler’s warranty valid, you will have to service it annually and be sure to have the service record completed and up-to-date. We offer one off servicing as well as low cost monthly Edinburgh boiler breakdown cover.
