First tip I will give you is to go to a proper decorating shop and buy either crown or dulux 'trade' paint if you can. I know for a fact that the big buckets of emulsion you buy in homebase & b&q is not the same quality as the stuff you get in a decent hardware shop. It is like dishwater in comparison and the 'white' is a grey colour!
Doesn't matter that it's a decent brand like crown, when homebase order a batch of paint from crown paints they want it for a certain price. To be able to supply it at that price crown make a cheaper batch of poorer quality than normal.
Most of the oil based paints yellow now since they reformulated them. Last time we decorated we were recommended to used oil based dulux satinwood and it seems to be staying white. The water based stuff stays white longer but is has poor coverage, not as nice to apply and nowhere near as durable.
