I like to use Cuprinol Green, AFAIK it is the most effective wood preserver.
I am told that if you read the ingredients, usage instructions and safety warnings on the Wickes own-brand, they are identical, and there may be a reason for that.
If you can't find the Green one, the Clear is also good, though it contains zinc not copper.
