Keeping a Heavy Machine on a Domestic Suspended Floor (UK)

I am guessing the whole thing must weigh at least 100Kg, possibly 150Kg or even more (my worst case estimate is 200Kg). I am concerned whether the floor of the upstairs room where I now have it can bear the weight. I have placed it right next to a load bearing wall to ease the strain on the joists. Can anyone tell me what sort of weight a normal UK upstairs floor can bear? If my guessed weight is anything close to the limit I will weigh parts of the machine to get a more accurate idea of the actual weight. Thanks Rob
