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.

Frequently asked questions

Good questions.
Straight answers.

Some of the most frequent questions we get asked.

Your Thermwise cover begins on the date your application is submitted. A 30-day waiting period applies before you can make a claim. This helps prevent claims for existing issues and keeps policy costs affordable.

Moving to Thermwise is simple. If you already have cover elsewhere, you should be able to cancel your existing plan and join us. Call 020 3962 0533 for guidance.

No. If you cancel within 14 days of setting up your policy, we’ll provide a full refund of the premium paid for the current policy period, with no cancellation fees. You can cancel at any time after this period, although cancellation charges may apply. Please refer to the Privacy Policy and Terms & Conditions for full details of your cancellation rights and any applicable charges.

Depending on the plan you choose, excess charges may apply. Standard plans do not include an excess fee, meaning you won’t pay anything for engineer callouts. If you select a policy with a fixed £60 excess, a £60 charge will apply for each initial callout.
This fee is non-refundable but covers any follow-up visits required within 30 days to resolve the same fault identified during the first visit. Your annual boiler service is always included and does not incur a callout charge.

Your annual boiler service is typically carried out between March and October. Once you join one of our plans, we’ll let you know the month allocated for your service. As your service date approaches, one of our engineers will contact you to arrange a convenient date and time.
