Your filter is AFAIK also a water conditioner which will allow you to have a scale free kettle SO if you haven`t a problem with carrying the bags of salt upstairs to the softener - go for the one you have upstairs - And trust the filter/water conditioner to work on the sinkHi. We do not have any storage tanks. It is mains fed throughout and hot water via combi boiler.

Hi again.
I believe there is a branch in the mains service pipe, before the stop cock as you say. When I shut the main stop cock I don't get running water anywhere apart from the kitchen which is at the back of the ground floor. There is a further stopcock situated under the breakfast bar which stops the supply to the kitchen.
It seems that I have options:-
A third quite radical solution just came to mind. What if I was to install one softener under the kitchen sink as previously envisaged and a further softener upstairs to service the rest of the property? Has anyone ever done this or does it seem a step too far?
What about the hot water at the kitchen sink? I believe this would be hard and would therefore cause the same problems ie limescale etc. Or can this also be filtered?
