Please Help!!!!!!!

I have just taken this extract from the TGWU website. Hope this helps you.

Q I work in an office that is freezing in the winter and stifling in the summer. Is this allowed?
During working hours the temperature in all workplace inside buildings shall be 'reasonable'. The method of heating or cooling should not give off dangerous gas or vapour. The workplace should also be supplied with sufficient thermometers to check the temperature.

What is a 'reasonable' temperature? The Approved Code of Practice (ACOP) to the Workplace (Health, Safety and Welfare) Regulations 1992 indicates that this is a level that provides reasonable comfort without special clothing: this would be normally at least 16潞C or at least 13潞C where much of the work involves serious physical effort (16潞C may be too warm in this situation). There are no legal maximum temperatures; however, the TUC is campaigning for a legal maximum workplace temperature of 30潞C, or 27潞C where strenuous work is being done.

The ACOP recognises that this may be impractical where there are hot or cold processes, for example, in food production where particularly cool temperatures may need to be maintained to ensure food safety. In this situation, the employer should first consider taking steps to minimise the risk to employees, such as enclosing or insulating the product, keeping chilled areas as small as possible, or pre-chilling the product. If it is not possible to take such steps, then the employer should consider other measures such as providing local heating for employees, excluding draughts, and/or using duck boards or other cleanable floor covering to isolate workers from cold floors. If a reasonable temperature is still not achievable, then the employer should provide protective clothing and heated rest facilities, and set up systems of work to minimise the length of time of exposure to uncomfortable temperatures, for example, rotation of tasks to enable workers to go to heated areas.

THROW COLD WATER ON YOURSELF IT MAKE YOU FEEL ALOT BETTER
Ask to have air conditioning units put into place
Stop whinging - I'm a chef and my kitchen get up to 130f sometimes - just get on with it and drink plenty of water.
There is no maximum temperature as you rightly say. All I can suggest is to hire some portable air conditioners. If you need a fiurther excuse, check out the recommended manufacturers' maximum operating temperature for your computer equipment etc. and say that has to be your maximum temperature other the stuff will pack up or become unreliable.
Install a local air conditioner ,
(window unit for the room) , many here do it.
Unless they put in central HVAC - that is the best.
I have central in my home too , but the local units are so cheap , you could pay for it yourself.
