The mains UK voltage standard is 230 volts, with a frequency of 50 hertz. This voltage standard was established in the UK as part of the European harmonization of electrical systems. It ensures compatibility and safety across various appliances and devices used in the country. It’s important to note that some appliances, such as certain laptops and mobile chargers, are designed to be compatible with a range of voltages (110-240 volts), allowing them to be used in multiple countries with different voltage standards.
