Small and medium-sized law firms keep an average of £354,000, or 60% of their funds, squirreled away in business savings accounts, bank research has revealed. Charities invest the most, 77% of total funds, in business savings and the national average is 57%, according to research by Hampshire Trust Bank. More than one quarter of law firms said they were increasing the amount of cash in their firms, to build a cash buffer against unpredictable times following the EU Referendum.
