Your landlord must register your deposit with a tenancy deposit scheme.
Your tenancy agreement should set out your'd and your landlord's obligations. In addition there are statutory rights.
Maintenance of the boiler is the landlord's responsibility as the landlord is under a legal obligation to provide constant hot water and heating.
Replacement of white goods is not down to the tenant unless damaged or destroyed by the tenant.
