In short: Responsibility for windows in a leasehold flat depends entirely on the lease. In many leases the windows form part of the structure or exterior that the freeholder repairs and recovers through the service charge; in others they are "demised" to the leaseholder, who repairs and replaces them at their own cost, usually with consent. If the freeholder replaces windows across the building and any leaseholder's share exceeds £250, they must follow the Section 20 consultation process.

Frequently asked questions
