Does buying flooring in the UK really work when you add in transport, exchange etc? Anyway for my money I'd say the following: depends on your budget! If you can afford it sold wood is obviously the best product- it sits well on the floor, looks solid, lasts well and may be refinished. But to get the best from it have it fitted by a good installer- afterall solid is expensive. Next best is semi-solid- looks good too, but you'll know it's semi-solid, it's pretty cheap now, quick and easy to lay and will last well if looked after. Laminate is fine in bedrooms etc where much of it will be hidden by furniture anyway. It's dirt cheap, looks cheap (in my opinion) and is very serviceable. If the house you're buying is your "forever home" (as I've heard them called!) I'd stretch and go for solid over semi-solid anyday. But if you envisage trading up in the near future then I'd go with semi-solid- it'll cost you half as much and you can't take it with you!
Best of luck with it anyway.
