OneProtect
Keeping your boiler and heating system in good working order throughout the year takes more than a single annual service. Unexpected faults, parts that wear over time and the general demands placed on a central heating system mean that repair costs can arise when you least expect them. OneProtect is Thermwise’s own care plan, designed to give homeowners a straightforward way to stay on top of boiler and heating maintenance with a regular, planned approach.
Rather than waiting for something to go wrong and then facing the cost of an unplanned repair, OneProtect is built around regular, proactive attention to your heating system. It’s a structured plan that keeps your boiler maintained and puts Thermwise on hand when you need us.
