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

I just can't let that pass.

The overwhelming reason for regs to change is that there are vast
departments of people who's job it is to create new regulations and still
others who's job it is to enforce them. If they didn't keep changing the
rules, they'd have nothing to do.

Therefore my question is what soultions are available to achieve a dry
loft? I will not consider a combi bolier solution, mainly because
there is no backup for hot water should it fail, and unless you have
good reliable mains pressure power showers are out of the question.
Ideally I'd like to store my cold water downstairs in the utility
room, ofcourse this would not work with a standard tank as there would
be no pressure for taps above the tank etc etc.

I'd put a tank in the roof, and achieve karmic compliance-bliss by fitting
every bit of clobber going to make it comply with the water by-laws. You'll
be able to delight in fitting little strainer to stop insects coming up the
overflow *AND* spend time calculating the flow resistance of said strainer
to make sure it doesn't impede any possible overflow.

Then you can worry about whether there's enough insulation around/over the
tank (and did that lid clip on nicely?) and whether you've left a sufficient
gap in the insulation underneath it - while still making sure it's properly
supported.

If you're going to store cold water, which might be a good idea if your
mains flow-rate is poor, then the best place to put it is where gravity can
deliver it back to the rest of the house.

HTH,
