Has anyone had any problems with mains water pressure at their property?

I understand that the water company is legally required to provide water at mains pressure of a minimum of 1 bar (which is often the minimum required to use electric showers or combination boilers). Could anyone advise if this is the case or not?

If it is the case, and if my water pressure is below 1 bar, what would you recommend my course of action should be?

Thanks,
KK
