Generally 10p/10c per pip minimum trade size, probably a good choice for forex trading small accounts with tight risk management.

If you have a small amount of risk capital, Axitrader may be the one for you to make sure you can do conservative risk management (see also my videos on the subject of risk management). Make sure you do your own research and take advice where necessary.

In the UK, make sure you open a spreadbet account (for tax reasons) running MT4 (Metatrader4), a live account and a demo account.

Wishing you good trading.
