If your flooring consists of reinforced Concrete built with standards that
are at least a bit "compatible" with current Eurocodes (construction
Statics and safety margins) and EN 206 (Concrete) the structure should
easily be able to handle your load... From experience people tend to put
much more load on their floors (Aquariums etc.) and I have not seen major
structual damages because of private loads in the last 10 years. Most
damages came from people disregarding plans, standards etc.
If you still have some kind of fear, ping me privately - I have enough
engineers around me at work ;)

For comparison, the wooden floor in my garage is also designed for 250Kg
per m2, and you have seen how that has been made.
Could you rebuild my attic? :)
