The timeline for commercial property redevelopment in London typically ranges from 6 to 18 months, depending on factors such as property size, structural complexity, planning permissions, and the scope of internal works. Smaller refits with minimal change-of-use may be completed in under a year, while projects involving listed buildings, major structural alterations, or multi-use conversions can take significantly longer. Early engagement with architects, planners, and local authorities (such as borough planning departments) can help streamline approvals and reduce delays.
