Avoid screwfix / B&Q. They used to sell Wypall under their own brand. That was great stuff. Now they're cheaped out and sell something horrid.
Aldi / Lidl white roll is fair value when it comes into stock time to time.
Wypall brand stuff is available from ebay and specialists. It comes in many variants and is costly, but much better. L30 is higher spec than L20. As it gets dearer, it goes from 2 layer to 3 layer, and they do make versions like the one that Screwfix used to sell that is low lint. Important for cleaning things that you don't want to leave full of fluff. The thing to know is that these big companies make paper for different applications and once you have worked out the right one for your needs, you should be happy.
