The major difference between Ikea UK and France kitchens is the price. They are around twice as much here in France. All other Ikea stuff seems to be cheaper in France, but not kitchens. Maybe it is because the French are not really fitted kitchen lovers. We bought our kitchen in Ikea Bordeaux - still seemed preferable to shipping the whole lot over from Croydon or Wembley. French plumbing fittings can be picked up in any Ikea France store, although some of them are a bit cheap and cheerful. As for the quality, it is probably the best flat pack kitchen I have ever put together - and I've done a few. One downside is the hangers for the units, they don't have quite the adjustment of the more expensive brands. If you can, go for their solid wood worktops, they are great, half the price and much better finish than the ones in the DIY sheds around here. Hope this helps.
