Council Serves Repair Notice to Mentmore Towers Over Unfinished Bat Survey
8/26/2026, 8:40:45 AM
Core Event
Buckinghamshire Council issued a formal listed-building repairs notice to Mentmore Towers Limited on August 4. The notice requires the owner of Mentmore Towers—a Grade I-listed country house in Aylesbury, Buckinghamshire—to appoint a licensed bat ecologist and commence three bat-emergence surveys within one month, or face compulsory purchase by the Secretary of State. The council also demands that repair work on the deteriorating roofs, chimneys, rooflights, roof lanterns and leadwork begin promptly, with weekly inspections by council and Historic England officers once work starts.
Background & Context
Mentmore Towers was built between 1852 and 1854 for the Rothschild family and is the only major surviving work of Sir Joseph Paxton, architect of the Crystal Palace. The mansion served as Wayne Manor in Christopher Nolan’s 2005 film *Batman Begins* and has appeared in other productions such as *The Mummy Returns* (2001) and the 2026 film *Pressure*. Ownership passed to Mentmore Towers Limited in 1999; the company is controlled by Syrian-British property developer Simon Halabi, who was listed among Britain’s wealthiest individuals in 2007 but declared bankrupt in 2010 over a $76 million loan.
Historic England lists Mentmore Towers on its Heritage at Risk register, describing its condition as “very bad,” its vulnerability as “high,” and its trend as “declining.” Planning permission for roof repairs was granted in 2016, yet the work remains unfinished.
Data & Statistics
- Grade I-listed buildings constitute roughly 2.5 % of all listed structures in the United Kingdom, a category that includes Buckingham Palace and the Tower of London.
- The repair notice specifies that three bat-emergence surveys must be completed by August 2027, alongside any required Natural England licences.
- Mentmore Towers has been owned by its current company for over 25 years.
Official Statements & Responses
Council deputy leader Peter Strachan explained that owners have a one-month window to begin the bat-survey process and provide evidence of a qualified ecologist’s appointment. He added that failure to comply could lead the council to seek government approval for compulsory purchase, subject to further legal action.
The agency also requires the owner to demonstrate that a contractor with experience in large-scale listed-building repairs will be engaged.
Criticism & Opposition
Save Britain’s Heritage, an independent charity dedicated to protecting historic structures, welcomed the council’s intervention. Its director, Henrietta Billings, urged the owners to act immediately, stating:
“We welcome this action taken by Buckinghamshire Council requiring the current owner to carry out urgent and overdue repairs to this great house,” — Henrietta Billings, the director of Save Britain's Heritage
The organization argues that the landmark has been “neglected for too long” and calls for swift remedial work.
What’s Next
- One-month deadline: The owner must submit proof of a licensed bat ecologist by the end of the period following the August 4 notice.
- Survey deadline: All three bat-emergence surveys must be finished by August 2027.
- Repair commencement: Once surveys are completed and a qualified contractor is appointed, weekly inspections by council and Historic England officers will begin.
- Potential compulsory purchase: If the owner does not meet the stipulated requirements, Buckinghamshire Council may apply to the Secretary of State for a compulsory purchase order, initiating further legal proceedings.
