ud555,
going back to your question on previous page, I imagine you'd be looking at between 80p - £1 depending on the arcade your trading at on the volume you are doing. Also depending on what contracts you trade (whites, reds, greens) you will get a small rebate possibly £500pm if your lucky. You really need to be trading at least 20,000 lots to get on liffes slp rebate scheme.
