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.
