Sue keep your receipts and keep reminding the council you intend to chase for their payment. The impression I get from your decription is that you've paid for the leak damage to be fixed, not the leak. This will only be OK if the leak was a one-off, i.e. a flood due to accidentally over-filling the bath. However, even if it's a one-pff, you had to deal with it and suffered financially and are due your bread back. If it happens again, you have the right to take care of remedials yourself if it's dangerous or if you've tried repeatedly to get council / leaseholder to repair the problem. Again the leaseholder/council owe you.
