"Hi,

There is no issue, just to add/install correct steel beams and it will be good to go.

"Existing foundations
Generally the additional load (weight) from construction and use of the new loft room(s) does not mean a significant increase on the load being transferred to the foundations.

However, in some cases, the increase in load could be significant and the adequacy of the existing foundations to carry this extra load will need to be checked. It may be necessary for the capability of the foundations to be increased by underpinning them. A structural engineer or your building control body will be able to advise you."

"There is no issue with the weight of a loft conversation going on to your house providing you have all the Correct Steels and calculations for your loft conversion"

"No it is not usually an issue , the independent floor will be supported on the wall plates and load bearing walls. Calculations will be required for building regulations.
