I suggest you google what happened to Beaufort securities that the FCA forced into insolvency a few years ago.
Special administrators can dip into client funds to cover their costs if the business had insufficient funds to cover the administration fees, which is likely if a business is 'insolvent'. In the end I believe the FCA footed the bill, but things are not as 100% safe as a lot of people think.
I would now only trust a large UK based broker with a strong financial position. Cheaper isn't always better.
