The one thing I'd say is that it is really hard to picture what a whole room will look like just by looking at a sample. We spent more on the kitchen titles and saved on the laminate for the rest of the ground floor, but we ended up liking the laminate much more!

Thank you so much thats really helpful!

Karndean laminate flooring from Trade Carpet Wimbledon, near the Lidl and the new stadium. Went with a light grey pattern that mimics stone and we love it. We wanted to go with Amtico (many friends have that) but it was just too expensive. I double checked my invoice - it was this one:

Can anyone recommend a laminate flooring provider and fitter they have had a good experience with. Would rather go with a recommendation.
Thank you!
