You can get that from the Money Advice Service. On 7 August 2014, it headlined:
“One in 11 Britons has less than £10 a month disposable income”
One in 11 people, or 4.5 million British adults, have less than £10 a month left over once they have paid their essential bills, research from thinkmoney has found.
You’ve probably already seen that in the news in August, but if you missed it and are curious about the rest of the article, you can read it here.
If that bit of news escaped you, then you may be unaware of the results of this other study too (reported by The Independent).
