Existing long leaseholders already in the building (if buying a partly-sold block) have statutory rights: Right of First Refusal, lease extension, Right to Manage, any of which can affect whether this is even possible.

Ground rent reform (Leasehold and Freehold Reform Act 2024) is still only partly in force: check the current rules before assuming you can charge ground rent on new leases.
