You have a number of obligations as follows:

• Repairing covenants: under the Landlord and Tenant Act 1985, the landlord must look after the structure and exterior of the property and the installations for the supply of services (gas, electricity, water, sanitation and heating). The landlord should also look after the roof of the property, drains and gutters.
• Gas safety: under the Gas Safety Regulations a landlord must have any gas equipment at a property inspected annually by a CORGI registered plumber and provide a copy of the gas safety certificate to the tenant.
• Furniture, electrical equipment and general product regulations: these regulations require furniture to be fire-resistant, and all electrical equipment and other items in the property to be safe.
• Covenant of quiet enjoyment: tenants should be able to live without any interference. The landlord cannot enter the property without the tenant's consent (except in an emergency), should keep the property in a proper condition, and should not do anything or allow anyone else to do anything which would affect the tenant's rights e.g. cutting off any utility services to force a tenant to leave.
• Insurance: the landlord has an obligation to insure the property building but tenants are responsible for insuring their own possessions.
