Expert comment
Explain why a zero-bills promise needs careful checking
A property expert can point out that a guaranteed period without energy bills is not the same as a home costing nothing to run forever.
Expert comment angle: Offer buyers’ journalists a clear explanation of what to check in the scheme’s terms, including what happens after the ten-year guarantee.
Why: It gives readers a useful, buyer-focused way to assess a new mortgage offer without dismissing the potential savings.
