One other alternative is to use a tank and pumps. If you are planning a
shower in the loft, this could be problematic due to the head being above
the tank water level.
Then you have the choice of replacing your water main with something decent
such as 25mm MDPE (assuming good street pressure), or using a pressurised
storage tank, as would normally be found on a well system. This basically
involves fitting a well type water system, but rather than putting it in a
well, putting it in a small tank filled from your puny mains supply. The
pump in the well system keeps the outlet water pressure at a nice high
pressure and just tops the tank off slowly when the level drops too much.
Could be expensive, though.
This may be well worth doing. I have a feeling the mains pressure is
still fairly poor - but obviously the flow rate limitation is not as
great. The current incoming pipe looks to be 1/2" copper - and I would
not be supprised if its a bit constricted by now either.
Well this must be it then.
As long as you have a water "pressure" of approx 0.8 bar then this works
Combi's: Ferrolli Modena and Dominia and the Ariston Microgenus all operate
on very low pressure: 0.1 bar on the Dominia (the lowest of any combi)
Whatever you do, look into getting the mains uprated to 15mm blue plastic.

There is a unit available that is basically a sealed cold water tank, very
similar to an expansion vessel but much larger and suitable for potable
water. If the standing pressure (with all outlets closed) is Ok this will
provide a quantity of water at a useable pressure. I cannot recall maker
etc, it was just lurking in the corner of the centre where I did my unvented
training, if anyone is seriously interested I can contact them for details
