Thank you both - I think we'll give it a go with hot water "off" and see how long it takes for it to pull through to the shower (upstairs) then.

I was not suggesting you switch 'hot water off'! You will get no hot water at all.

There will be a setting to turn off hot water being stored in the small internal tank in the boiler - read the handbook. As I stated in the post above:

if you don't want the boiler's small internal (HW) tank to heat up, you simply switch it off. You then heat water on demand - the whole purpose of a combi. The only penalty of switching off the HW tank is that it will take longer for the HW to reach the taps.
