How much should you tip in United Kingdom 🇬🇧?

As service workers in the UK are paid an acceptable wage, they usually don't rely on tips to make a fair living. Tipping is however still a good way to show appreciation for good service, in which case it is common to tip around 5-10% of the total bill or rounding up to the nearest 1, 5 or 10 pounds depending on the bill amount.
