What is UK domestic voltage

[joules99]

I thought that a few years ago the UK domestic voltage went down to 230v but recentley I was checking a cable with a multimeter and it was 245, I checked at a few other houses in different areas and it is all around 245, what is the actual official UK voltage supposed to be?

Following voltage harmonisation all electricity supply within the EU is now nominally 230 V +/− 10% (though some countries have stricter specifications: for example, the UK specifies 230 V +10% -6%). In practice this means that countries such as the UK that previously supplied 240 V continue to do so, and those that previously supplied 220 V continue to do so.

Hi Kempie, What you have said is correct and is a very good example of ''moving the goalposts'' by the EU. They bent the rules to make sure that every country complies with the new standard without anybody actually changing anything on their power systems.
