Dear Sir or Madam I live in an apartment on the second floor. About 6 months ago the AOV blew off in high winds over a bank holiday and a temporary fix was implemented by our management company. The AOV was bolted into place so that it cannot open. Despite repeated requests to the management company this has still not been repaired. Is this in breach of fire regulations for shared buildings and would this invalidate building insurance in the event of a fire? I thank you for your time and attention.

If this is an AOV forming part of the smoke management system rather than just environmental control then it affects the efficacy of the built in fire strategy (usually stay put with smoke extraction to the communal space) and would potentially be an offence. 

You should contact your local fire service's enforcement department, who will inspect and advise accordingly, and as a last resort can carry out formal enforcement action.
