@GoodAdes if you mean for food/drink in restaurant/bar/pub then most places will add a tip/service charge of 12.5% for everything else, goods and services, getting a cab, buying flowers, having someone tattoo you, you don't have to tip at all, unless you feel so inclined. And most in the UK don't feel the need to, unless of course they've spent time in the states and feel odd not doing so.
