Easiest way to diversify savings
Having savings only in your home currency is relatively 'low risk' compared with other types of 'low diversification'. This is because, in a simple case, your future cash outflows will be in your home currency, so if the GBP fluctuates in value, it will (theoretically) still buy you the same goods at home. In this way, keeping your savings in the same currency as your future expenditures creates a natural hedge against currency fluctuation. This gets complicated for goods imported from other countries, where base price fluctuates based on a foreign currency, or for situations where you expect to incur significant foreign currency expenditures (retirement elsewhere, etc.). In such cases, you no longer have certainty that your future expenditures will be based on the GBP, and saving money in other currencies may make more sense. In many circumstances, 'diversification' of the currency of your savings may actually increase your risk, not decrease it. Be sure you are doing this for a specific reason, with a specific strategy, and not just to generally 'spread your money around'. Even in case of a Brexit, consider: what would you do with a bank account full of USD? If the answer is "Convert it back to GBP when needed (in 6 months, 5 years, 30, etc.), to buy British goods", then I wouldn't call this a way to reduce your risk. Instead, I would call it a type of investment, with its own set of risks associated.
