If you are after real climbing webbing then £1.60-£1.70 per meter is about as cheap as you will get it. But apart from beeing expensive it's also heavy and bulky. If you don't need 2 tonnes braking strenght I recommend this https://www.profabrics.co.uk/products/traditional-weave-20mm?variant=5940931267
This is what I'm using for my hammocks, non stretching and rated to 750kg. They have more options as well on that website.
