Thanks, I can't see anything in the Rental Agreement but I have decorated a few rooms since I have lived here and my landlord knows but has never offered to pay so I guess it is up to me.
I've never heard of a council or housing association taking responsibility for the interior decoration of their rented properties (other than 'between tenants') so I would assume that leaving it up to tenants is very much the norm with rented properties.
Thanks all, to be fair I have always been happy to do my own thing and pay, never gave it much thought until people started asking me why I was paying for it. I too have always been under the impression that the outside is up to the owners and the inside up to the tenant.
I've always decorated my rented properties, but I've always checked with the various landlords and told them what I'm planning to do. The landlord might redecorate in between tenants, but not otherwise.
