Must take that up with them, they're supposed to use the IEC definitions.

Those aren't IEC definitions BAS, they're from Wikipedia, written by someone who hasn't checked their factoids.

The article claims they are.

If you have access to the correct definitions, please correct the article.

Those voltages appear in 7671, except HV is simply defined as "normally exceeding LV".

Yes, I should, but so could anyone else - the definitions are in the public domain. http://www.electropedia.org/

Was it ELV or SELV in this case?

Medium Voltage as defined by 14th Edition;

250-650V

It's worth remembering that even if ELV is not an IEC definition, and sits in the lower end of the Low Voltage range, not under it, the really important reason it matters still holds, as it says in the Wiki:

If you start getting involved in doing your own electrical work, and start learning about regulations etc you’ll come across references to “Low voltage”, and it’ll be no good you thinking that that means 12V.

The Building Regulations, for example, which are law in England and Wales, contain a section on electrical safety, Part P, and the legislation says:

The requirements of this Part apply only to
electrical installations that are intended to
operate at low or extra-low voltage….​

So if you don’t realise that “low voltage” includes your mains supply of 230V, you might think that the law doesn’t apply.​
