Potentially, but depends on the style of trading - timeframe, scaleability, risk, returns.
If you can make a couple of ticks every day on a thousand contracts, you'll be making a million a year. This would obviously be pretty good, but if you started with a £10000 account, it would take a long time before you'd be trading that kind of size. In this scenario, going to a firm who would allow you to play with some decent size would be ideal.
