What is the standard voltage of a domestic electrical supply in the UK?

The standard voltage of a domestic electrical supply in the UK is 230 Volts. This value is established by the harmonization of electrical standards across Europe, which has set 230V as the nominal voltage for domestic supply systems. This means that the voltage provided to homes is typically within a range that can fluctuate, but it will average around 230 Volts.

The use of 230 Volts accommodates variations due to factors such as load changes and distance from the distribution transformer, but maintains safety and effectiveness for household electrical appliances. While you may see references to other voltages such as 240V, it is important to recognize that these figures are interrelated, and the standardization around 230V represents the most current and widely accepted figure for users across the UK and much of Europe.

In contrast, 110 Volts is typically used in construction sites and temporary installations to enhance safety, while the other voltages mentioned, such as 220 Volts, do not reflect the current standard for domestic use in the UK.
