a risk assessment has to be site-specific.
You have to identify the risks and hazards of that particular building.
It will be no use handing in some generic one prepared by someone else, as no two sites are the same.
Some companies will only provide a risk assessment when their quote is accepted, as it can take several days on some larger sites. Or maybe they'll offer to complete a risk assessment in advance, but only for a fee as a consultancy.
If you give them a generic one, they'll instantly know you don't know what you're doing.
