These figures also show how high rents are limiting the choice of young people starting out. Using the ‘30 per cent rule’ for 22 to 29-year-olds, and taking their average budget as £780, they wouldn’t be able to live in London, Edinburgh, Oxford, Bath and Cambridge. Younger still, those aged 18 to 21 with a budget of £550 a month are excluded from most major cities in the UK, although they would be able to afford average room rents in areas such as Liverpool, Swansea, Sheffield, Wolverhampton and Aberdeen.
