Some brokers offer "segregated accounts".
Here is a quote from Dukascopy:
"Clients' Trading Accounts with Dukascopy Bank can be funded via money transfer, bank guarantee, credit/debit cards funding or segregated accounts with Swiss Banks. The custodian service, in cooperation with a number of Swiss Banks, allows clients to keep money in their banks while getting credit line to trade in the Swiss FX Marketplace. The custodian service consists of automatic daily settlement of P&L and trades in the client's bank account. In this case, clients trade directly with Swiss Forex Bank & Marketplace from their personal Swiss Bank Accounts, without making funds transfer to Dukascopy Bank."
There are some other brokers also offering this service however most of the time it is only for large accounts (100k+).
Another option is keeping the money in your own bank account: if you plan to trade a 50K account, deposit 10K in to the broker account and keep the other 40K in your own bank, if you get a DD you can refill the account. This way if the broker would fail and you are not protected by FSCS or any other service, you lost only 20% of your trading capital instead of 100%.
