Finding a good quality non-stick frying pan is difficult – there are so many tickboxes that you need to check. But arguably the most important? The non-stick coating and its ingredients. You need to ensure this is tough enough to withstand daily use, while checking it's free from those forever chemicals you want to avoid.

I've spoken with the experts to find out just how long the shelf life is of a good non-stick pan. When I say shelf life, I mean how long yours can be used to cook with, almost daily. I'm not talking about those pans that sit in the back of your cupboard and get used just a couple of times a year.
