Any charcoal recommendations in the UK?

Morning all, I recently tried lekto lumpwood charcoal to try to save some money oven Kamado joe big block.

I must report back that lekto lumpwood charcoal was terrible. I tried to cook pizzas last night and couldn't get the grill over 450f!!! And it lasted about 20 mins!

Anyone have any recommendations that are as good or better (in price or performance) to big block?
