If you ring the HSA they most likely will write to your employers rather than visiting your office and ask them to write back confirming that they have rectified the situation. I have come across instances were the HSA have been rang due to a person being observed falling of a scaffold on an unsafe building site and their resposnse was to state that they would write to the main contractor on site about the incident. However as there was no main contractor named on the site signange and the complainant did not know who they were she was told by the HSA that there really was nothing they could do......
If your working enviorment is too hot then your employer needs to take steps to rectify this. They will not be expected to provide aircon (if in Ireland) as the climate is such that in a normal office enviroment it should not be required given our climate and relatively few very hot days per year. They will however be required to provide fans and / or other cooling devices e.g. window blinds, etc in order to make the workplace cooler. Improved ventilation would also be required unless it could be shown that it was too difficult to achieve (not 'practicable') or would not help the situation.
You should ask to see a copy of the company safety statement and check if office working is risk assessed. If you have no company safety statement then that's a non compliance with statutory requirements and then you may have a better case to ring the HSA.
