    it very unusual to find a garage with a concrete floor that suitably smooth and level enough to take tiles ..rubber?  ..majority of garages in uk do not have a membrane

    Rubber tiles should be enough, so long as they are thick.  I put down some vinyl tiles (floating floor type) and the moisture which the cement attracts caused the tiles to bow at the corners. So, if you are unsure, put down a moisture barrier that will take the abuse of being under a rubber mat.  

    As for needing permission to change the garage, unless you are changing the floorplan, such as adding walls, or taking out the door, you do not need any 'permission' or permits. Just to be sure, call your local codes office and inquire.

    One thing you can do is take a piece of plastic about the size of a trash bag and tape it to the floor. Put tape all around the edges so it is completely sealed leave it for 24 to 48 hours and see if any moisture accumulates under the plastic. 

    This is what several laminate flooring manufacturers recommend.

    I might apply a sealer like ToughCrete Concrete Sealer but I don't know how it's been treated or what condition it is in.
