What is the currency in the UK?

The currency used in the UK is the British Pound Sterling (£/GBP). Credit and debit cards are widely accepted, with contactless payment common for purchases up to £100. Cash can still be useful for small businesses, markets, and rural areas. Major cities have plenty of ATMs, but rural areas may have limited access. Currency exchange services are widely available, but rates are typically better at banks than at airports or tourist areas. Always check for fees before exchanging money.
