If you have bought a property in a shared block on a JMB estate, or if you have bought a house that receives services from the JMB and the council, then you will have bought your property under a legal arrangement known as leasehold. This means that you have a legal agreement – the lease – between yourselves and Southwark Council which sets out responsibilities on both sides. You are legally known as the leaseholder of the property and are legally obliged to pay for the shared services you receive through service charges.
