Regarding the anti-social stuff, I would really like to see all landlords, not just HA, made responsible for the behaviour of their tenants with the right to evict them very quickly if complaints are made and proven to be true. Near neighbours would all be informed of the name and address of the landlord of any rented properties so that they can make a complaint easily. If the landlord failed to evict despite evidence (eg. photos of piled up rubbish, video and audio of noise and disturbance) he would be heavily fined and possibly lose the property. I think a whole lot of people would suddenly find themselves able to behave like civilised human beings in that case.
The problem of course would be deciding how much nuisance is grounds for eviction. The need for evidence would largely circumvent the issue of malicious calls, but the level would still need to be set to allow for people with mental health problems, ASD, LD and so on, who make noise because of their condition as the last thing we want is families whose children have ASD being put on the streets because of meltdowns etc.
Because the level would need to be quite high, bad neighbours could still make peoples lives pretty unpleasant without falling foul of the law.
I've noticed you post quite often about social housing Helena. Do you belong to some kind of pressure group (and can I join??)?
