Leasehold Ground Rent FAQ
Everything you need to know about ground rent increases, leasehold reform, and protecting your property’s value.
A doubling ground rent clause is a provision in a leasehold agreement stating that the annual ground rent will double after a set period (e.g., every 10, 15, or 25 years). This can make properties difficult to sell or remortgage as the lease progresses.
Most UK mortgage lenders will refuse to lend on a leasehold property if the ground rent exceeds £250 per year (or £500 per year in London). Some lenders also apply a cap of 0.1% of the property’s purchase price.
Yes. Under the Leasehold Reform (Ground Rent) Act 2022, ground rents for most new residential leases are restricted to a ‘peppercorn’ (effectively zero). For existing leases, you may be able to negotiate a lease extension or variation to cap the ground rent, though this usually requires legal assistance.
Ground rent is a payment made to the freeholder simply for the right to occupy the land. Service charges are separate payments that cover the actual cost of maintaining the building, such as cleaning, repairs, building insurance, and communal area upkeep.
