Overview
- A LoftZone survey of 500 estate agents published on Wednesday, June 3, 2026, found a boarded, accessible loft adds about £17,677 to a four‑bed home, £13,821 to a three‑bed and £9,867 to a two‑bed.
- Agents told researchers that cheap interventions can deliver big returns with some boarding and insulation jobs starting at roughly £260 and many installers saying work can be completed in a day.
- Survey results show strong seller and agent interest: 88% said homeowners seek cost‑effective value boosts, 92% said a clean, well‑presented loft speeds sales, and 19% recommend improving lofts on every listing.
- Estate agents reported buyer sensitivity to non‑functional lofts, with 45% saying shoppers were put off and 55% saying buyers lowered their offers when loft space was unusable.
- The findings stress practical fixes such as raised boarding, safe access, ventilation and lighting but are based on a single industry‑commissioned survey and have not been independently verified.
