The best currency to use in the UK is the British Pound Sterling, usually called the Pound or GBP (£).
Here’s what works best in practice:
- Use GBP directly for cash, card payments, and bank transfers in the UK.
- Avoid paying in your home currency when a card machine asks “Pay in INR/USD/EUR?” — choose GBP instead. This usually gives you a better exchange rate.
- A Visa or Mastercard debit/credit card with low foreign transaction fees is often the cheapest option.
- Carry a small amount of cash (£50–£100) for taxis, small shops, or emergencies, but most places in the UK are card-friendly.
If you are traveling from India:
- Exchanging Indian Rupees to GBP before travel is usually easier.
- Multi-currency travel cards can also help reduce conversion fees.
The official currency is issued by the Bank of England.
