Do Housing Associations have a responsibility?

I am a freeholder living next door to a Housing Association tenant. Yesterday, she drove her car into our boundary fence. It is my boundary fence and I am responsible for the upkeep.

She is an absolute nuisance, constantly dumping her rubbish/old furniture outside of her property, putting her rubbish into other people’s bins. The outside of her property is truly awful with old tin cans, tights, food all over the front path and garden. The HA seemed to have ignored all this, even though there is caretaker who has continually picked up rubbish outside her property and is fully aware it is hers.

My question is: she drove her car into my fence and now the boundary post has been pushed forward, is loose and the cross strut cracked, I would like it repaired and know that she will not do this or pay for it.

I want to ask the HA to repair it. Do they have a responsibility to do so as they are the either the leaseholders or freeholders of the property and she is their tenant? Any advice or information would be very helpful

Many thanks
