Most residential leaseholders will have paid the full market price for their flats and maisonettes. Yet the law does not recognise them as “owners” in the fullest sense of the word. Someone else will decide how, when, and by whom essential repairs and building maintenance will be carried out — and how much individual leaseholders will be asked to pay for those repairs and maintenance. That same person will decide with whom, for what risks, for what level of cover and for what cost the building is to be insured. That same person will, at their discretion, allow or refuse applications by individual leaseholders to carry out alterations to their homes. In rare cases, that person’s consent may also be required before a residential unit can be sold or sublet. If the leaseholder is affected by another leaseholder’s failure to comply with their lease, it will be primarily up to the same person to decide what (if any) action should be taken under the lease to bring that other leaseholder into line.
