The only thing that can be an issue in a 150 152 is maximum take off mass.
It's usually just a matter of paying attention not to top up the tanks.
Another point might be performance: on a short grass runway a hot day, especially if the actual TOW exceeds the MTOW, the aircraft won't take off.
Nothing to worry about if you don't exceed the MTOW and check performance before take off. Your instructor will do that, and will teach you how to do it yourself.
Some reckless instructors would not, probably not in the UK, but I saw reckless instructors elsewhere.
The DR400 is very much appreciated in France. Some models have a tricky nose wheel, and tricky seat locks, and you need a hat in summer.
