The idea of "class" is vague (and slightly offensive) which is perhaps why it is being used here.
In any case, "According to the Organisation for Economic Co-operation and Development, middle class is someone who earns 75 per cent to 200 per cent of the median national income."[0] and, as you say, the median "Equivalised household disposable income of individuals" is £29,900 according to the ONS.[1]
I'm not sure if "disposable" here means that the OECD definition doesn't apply, but I agree that the article would have been less misleading if it had used a less subjective term, and a less extreme definition.
