A routine pre-purchase survey has saved first-time buyer Sarah Mitchell from making a potentially costly mistake after uncovering a protected bat colony in the attic of a Victorian terraced house in Clifton, Bristol.
Mitchell, 34, who works as a physiotherapist, was in the final stages of buying the property when a Level 3 RICS building survey uncovered evidence of a colony of brown long-eared bats roosting in the attic.
“I had such specific plans for that house, including converting the loft into a home office and spare bedroom,” said Mitchell. “The survey quite literally saved me from making a £425,000 mistake. I would have been legally unable to complete my planned renovations without extensive ecological surveys and expensive adaptations. As a first-time buyer, those additional costs would have been impossible to manage.”
The brown long-eared bat is among the most common species in Britain and is protected under the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017. It is illegal to disturb their roosts, even unintentionally, with offenders facing heavy fines or even prison sentences.
Jason Weale, Director at Find My Surveyor, stressed the importance of comprehensive surveys: “This case perfectly illustrates why detailed building surveys are essential, not just for identifying structural issues but for uncovering potential legal and regulatory challenges. A basic valuation or condition report might have missed these crucial signs. The presence of protected species can significantly impact a property’s development potential and, consequently, its true market value.”
David Thompson, the current owner of the property, was also surprised by the discovery. “We’ve lived here for fifteen years and had no idea we were sharing our home with a protected species. We rarely accessed the attic space, and we attributed any sounds we heard to typical old house noises. We’re now working with local ecological consultants to ensure the colony’s protection while we prepare to relist the property.”
The discovery has prompted local estate agents to recommend RICS building surveyors more proactively to potential buyers, particularly for period properties where protected species are more likely to roost.
Mitchell has since purchased a new property that is more suitable for her needs. “This experience taught me the value of professional surveys. What seemed like an unnecessary expense potentially saved me from years of financial strain and legal complications. I’ll definitely be getting a full building survey on my next purchase.”
