boiler flue in possible breach (moved from Trade Talk)

Then you're back to contacting Environmental Health Department at you're local council, and they're duty bound to investigate.

After that, put in a formal complaint to the housing association asking them for a copy of their complaints procedure, and be prepared to taking it to the housing association ombudsman.

Complain about your housing association
You can also complain to the:

• council's environmental health department if there is a hazard to health or safety in your home and it is the housing association's fault. Use the Gov.uk council finder to find the contact details of your local council.
• health and safety executive if the housing association is your landlord and won't carry outgas safety checks

You're in a tricky situation, and sods law suggests that whichever way it goes, you're neighbor will know you've complained, but if it comes to an issue with him, point out that it's the installer that you've got an issue with, not him.

Best of luck.

Thanks so much for your advice; to everyone. Chaps you've been really helpful.

I suspect I'll be back on the forum soon with more queries due to neighbour's removal of interior walls etc, but thankfully there shouldn't be anymore plumbing concerns.

Best of luck.

Thanks! Great advice above btw. I'll do just that. And yes, it's not specifically my neighbour it's the work that's been done. Thanks again.
