Whether you are a homeowner, or you are a landlord running several homes, you need to think about how you are keeping your home and water heated. If you have an electric boiler, you might not need to service it as often, but a gas boiler has to be serviced at least once per year. An annual service by a Gas Safe Registered engineer ensures that your gas boiler maintains its integrity and most importantly, its safety. Sometimes, skipping an annual gas boiler service can leave your home insurance vulnerable.
Your manufacturer should be able to tell you how often you should have your gas boiler serviced, but in general, every twelve months is the norm for a boiler. The first service has to happen within that time to meet the warranty terms. Doing the boiler service every twelve months after that is just good sense to ensure your home and your insurance are covered. The cost to service a boiler depends on your manufacturer and it also depends on whether you are having any issues with the boiler or the entire heating system.
Gas boilers need to be serviced every year for the warranty and your home insurance to be valid, but you also want it to be working at its optimum level, too. Without a boiler, your home is cold, and you have no hot water. Getting on top of this early when any issues arise is just good sense.
