How to read this comparison

Headline details are agent or publisher claims unless a source-backed fact is explicitly marked verified. Aveno interpretations and calculations are labelled separately. Unknown means evidence is missing, not that a property fails a check.

Important missing informationBlackthorn House

Practical questionWhich accommodation is approved for its advertised use, and are access, services and heating independent?

Ask before you view

  1. Which accommodation is approved for its advertised use, and are access, services and heating independent?
  2. Can you provide the current EPC, commissioning certificates, warranties and recent measured energy use?
  3. What evidence can you provide before a viewing to resolve: Named architect, UPRN/title and planning/completion bridge?
  4. For Blackthorn House's advertised 5 bedrooms, which share a level with a bathroom and living space, and what steps are on the route from parking?

Occasional occupation: ask who checks this property while empty and what its services and insurance require.
