Flip... Why would you post any of that? it's not what the law says.. at all.
It defies belief why so many people post things they are only guessing at.
The Tenant has a right to Quiet Enjoyment for the duration of their tenancy
This right to Quiet Enjoyment trumps EVERYTHING.
this means - irrespective of what the contract says or doesn't say, the Tenant does not have to allow access for anyone at any time if they don't want to.
Sure the LL can ask, they can give 24 hours or more notice, but if the Tenant doesn't want to allow access there is little the LL can do. They can apply to court, but unless there is a real need, they are unlikely to be successful. This also includes viewings. Tenants don't have to allow them at any time if they don't want to.
Locks - the Tenant can change locks and actually does not have to provide the LL a key. Again the LL can go to court...
The tenant can change the locks and change them back for check out. Nothing the LL can do.
The LL cannot evict the tenant early. Neither can he deduct these costs from the deposit.
Why do I know this? Because I had a Landlady from Hell, who intimidated me and my child, tried to break into my home, tried to give me additional charges that were not included, and had not protected my deposit or got the gas safety cert done.
Shelter helped me enormously with the legal stuff, as did the CAB and experts in Lettings industry.
