Broker (UK?) with MT5?

Maybe this is asking too much too soon,

just as new to brokers, well this is important for me in deciding so thought I would ask straight-out…

Would like to start out with MT5 to get into good habits… (as am stickler for using latest/updated software)
Preferably UK company or very-well regulated US company (I will be researching extensively…)

Cheers,
