I have tenants that are wanting to put a dishwasher in. I have said no to supplying as the maintenance has been an issue with past tenants. There is already an empty space for it and all fittings are there. Tenants are willing to purchase and install themselves, also providing any maintenance to it and will take it when they leave. My question, is there any legal reason this cannot be done, apart from me not agreeing to it? Am I allowed to decline?
