ASTs are worthless - they give no security to tenants who can be booted out with two months' notice, no reason needed.
That isn't true.
You can't use s21 (the "no fault" possession claim) during the fixed term of the tenancy agreement. You can only use s21 once the fixed term has ended and it has become a rolling contract. Tenants and landlords can agree a new fixed term instead of allowing it to become a periodic tenancy. Many do precisely that.
During the fixed term there must be a reason for seeking possession, and not all of these grounds result in possession automatically being granted to the tenant. The main mandatory ground is the equivalent of two months' rent arrears.
I would also point out a tenant doesnt have to leave at the end of the notice period. If they don't, the landlord has to go to court to get a possession order. And then, if they still don't leave, the landlord has to go back to court again to get a Warrant of Eviction.
Similarly there's nothing to say the fixed term of an AST cannot be more than 12 months. In most cases people don't want to agree a longer deal- tenants in case their landlord is rubbish, and vice versa.
The tenancies used for social housing might be a good guide,
Housing Associations use Assured tenancies. These are pretty much identical to Assured Shorthold except there is no end date on the tenancy and therefore s21 doesn't apply.
HAs will usually issue Assured Shorthold tenancies to their new tenants, so they can get tenants out if they don't pay or don't behave. These will usually change to assured after 12 months, assuming the tenant has behaved properly.
It's only councils who still issue secure tenancies, and fewer and fewer councils still control social housing stock- most have sold/transferred to housing associations. And even councils will issue introductory tenancies- with fewer rights- for the first 12 months.
I'm a landlord and a tenant because I moved here. I'm renting my house out in England and renting my house here. My tenant isn't paying his rent whilst bitching about cosmetic issues in the house (e.g. the wooden worktops he hasn't oiled). So I'm paying my mortgage from my funds, as well as paying rent here.
As for all this talk of extending notice periods- the Tories reckon six months now, on top of the two months arrears that must exist to use a "mandatory" ground. The notice period has already gone from 14 days (which was too short) to three months (too long). This notice period is just to start Court action, btw: a tenant doesn't have to leave until a Warrant of Eviction is executed.
This just gives tenants even less incentive to pay the rent, because it leaves a landlord powerless to do anything about it. If my tenant stops paying entirely he could potentially owe me eight months rent before I can even start Court action. If that's not skewing things in favour of tenants, I don't know what is!
