New Heating System

1930' semi with conventional but old heating system. Potterton Kingfisher boiler, cylinder in bathroom, expansion and cold tank in loft. kitchen is directly above bathroom.

i favour a direct mains hot water system as the water pressure is very good here(Worthing) and will free up space in the bathroom and loft. Also due to the location of the kitchen and bathroom the hot water run will be no more than 2 metres. However we will in the future add a room with ensuite to the back of the house which will mean the hot water pipe run from the boiler will be about 5m maximum.

Is this within a combi boiler capabilities? Also if someone uses two hot water outlets at once am I right in assuming they will still get hot water but at a reduced flow rate. what would be an ideal rating and make of combi boiler to use.

If a combi boiler arrangement is no good any other suggestions would be welcome although I would like to lose the airing cupboard in the bathroom.
