I've read somewhere that in a year or two new regs will require a dry
loft for new builds. There is always a good reason regs are changed
and therefore although I do not have a new build I do like to be
compliant.

If they are going to enforce dry lofts they would need to first enforce our
water companies to deliver water under some sort of pressure 24 hours/day.
I'm okay but a friend's system drops to almost nothing at peak times so
things like the shower becomes unusable.
