Your lease will outline whether the freeholder has any responsibility for repairs. If you own a leasehold flat the freeholder may be responsible for repairs to the structure of the building, or shared areas. If you own a leasehold house it is unlikely that your freeholder will be responsible for repairs.
If your home has been damaged your insurance may cover the cost of repairs. Read your policy and make sure that the damage is covered. Your policy documents will tell you what to do if you need to make a claim.
Property sales are either on a leasehold or freehold basis. When you buy a freehold property you own the property and the land it sits on. If your property is a leasehold property you’ll have to pay an annual charge, known as ground rent, to the person who owns the freehold.
