If you can get it buy solvent based paint, the water based alternative is useless, i did a complete house last year for a customer and initially purchased water based gloss from b&q.
it was not so bad on skirting boards and on fairly thin door edging, but on doors, it was awful.
you can only lightly clean water based gloss, where as solvent based gloss you can wash and it is fine.
you will be far better off with solvent based gloss in my view. and my customer was well impressed with the finish on her doors, and i did everyone in her house.
