I've lost a fair amount on exchange scalping with Skrill. I try not to use them unless I absolutely have to. I'd try and find brokers that you can find with credit/debit card or bank wire.
You'll especially lose a lot if you are moving from GBP to USD in Skrill, sending it to the broker and then changing it back from USD to GBP on withdrawal.
If you're trading in USD - which isn't the best idea if you're living in UK - then you might want to look into getting a USD bank account and using CurrencyFair.com to change your cash GBP into USD through there before sending it via a payment portal. Although they also charge so you need to be using reasonable amounts to not lose out on their transactions, but for larger amounts it's definitely worth the 2-3% that Skrill scalp on the exchange.
