I was recommended Wiko Best paint by our decorator as a good replacement for v expensive farrow and ball.
Decorator said it was very chalky, but quite elastic so much better at hiding surface imperfections than f&b. I am really pleased with it, perfect finish.
It is flipping cheap, i've paid between 12 and 15 pounds for various 2.5 litre tins of it now, as they often have it discounted a bit when I've gone to buy it.
The only con is they don't really have it in stock all the time, they always seem to have the sample pots in every colour, but not the 2.5 litre tins, or only 1 or 2, so I always click and collect it now,
They have several that are just off white, Abode and Paper Linen both gorgeous, and we've just done a couple of rooms in Aylesbury duck egg which is gorgeous sort of hint of pearly green. We've put cantebury duck egg in the guest bedroom and I love it but it goes much darker than it looks online. We have a sample of Silver Birch which is a lovely soft grey but don't know if would be suitable in a bathroom.
