In England, Westminster City Council wants access to HMRC information to help investigate short-term lets in the borough. A letter it published on 23 September supports a proposed data-sharing agreement between HMRC and the National Fraud Initiative. That agreement is still being discussed, and the council says it would seek access if it goes ahead.
Westminster says matching property addresses with income indicators could help it find suspected breaches of short-let controls. It has not announced a new rule for hosts. The proposal concerns how the council might identify cases for investigation.
What applies now
Westminster’s guidance says freeholders, leaseholders and tenants with their landlord’s permission can generally offer a home for short stays for up to 90 nights in a calendar year without planning permission. Council-leased property is an exception; lease terms may also prohibit short letting. The council says it investigates reports of suspected breaches of the 90-night limit.
If you let a property for short stays in Westminster, keep a clear count of nights let and read the council’s short-term let guidance. Check any lease terms and permissions for that property. Our England holiday-let guide covers the wider rules, including the planned national register; this local data-sharing request does not bring that register into force.
