Edinburgh has been named the UK’s most unaffordable city for flatsharing, with room rents outpacing budgets by £1,028 a year, according to data from SpareRoom.
The flatshare platform analyzed nearly 240,000 UK room listings and advertisements in Q2 2026 to identify the cities with the widest affordability gap between asking rents and renters’ budgets.
Edinburgh tops the list with a significant shortfall
Edinburgh ranked as the most unaffordable major UK city for room renters outside London, with average monthly rents of £834 running £86 ahead of the average flatsharer budget of £748, resulting in a shortfall of £1,028 per year.
York and Derby occupied second and third place respectively, with rents outpacing budgets by £51 per month in York, equivalent to £611 annually, and a monthly shortfall of the same amount in Derby, adding up to £607 per year.

National picture shows stretched affordability
A SpareRoom survey conducted in July 2026 found that only 15.3% of UK renters spent less than 30% of their income on rent, the widely accepted affordability threshold.
Conversely, 37.8% spent more than half their income on housing, and 32% had moved in the past year due to unaffordable rent.
Festival effect and regional disparities
Matt Hutchinson, director of SpareRoom, attributed Edinburgh’s high rents to the festival effect, where prices spike during the summer months.
He also noted that York and Derby’s presence in the top three challenges the notion that rental costs are more manageable outside major cities. “Sizeable affordability gaps in York and Derby put paid to any expectation that rents will be more affordable in the north of the UK,” Hutchinson said.
The data highlights a broader issue: budgets are relative to earnings, and wages aren’t keeping up with rising living costs. This problem persists across the UK, with room rents outstripping budgets for over three years.
