£39,039 a year, checked against real London and UK-wide rent.
£39,039 a year — the ONS’s median full-time salary for April 2025 — works out to roughly £3,253 a month before tax. Whether that’s comfortable depends enormously on one variable: whether “the UK” in that sentence means London or almost anywhere else.
The numbers
Average private rent across the whole UK was £1,368 a month as of December 2025 — about 42% of that median monthly salary. In London specifically, average rent jumps to £2,268 a month, which is 70% of the same median salary on rent alone. At the other end, the North East averages just £762 a month, or 23% of the median.
That’s a roughly three-fold difference in rent burden depending on region, against the same national median salary figure — which is exactly why “the UK average salary” is a much less useful number than it sounds like it should be.
A number that also hides a lot
£39,039 is a median, not a mean, so it isn’t skewed upward by very high earners the way a simple average would be — but it’s still a single national figure sitting on top of real variation: full-time public sector median pay runs slightly higher than private sector (£807.67 vs £752.28 a week), and pay by sector varies sharply too, with finance and insurance having the highest share of employees in high pay of any sector ONS tracks.
The practical version of this question isn’t “is the average enough” — it’s “is a specific salary, in a specific city, enough for you.” This site’s UK salary calculator at least answers the first half of that precisely: what a given gross salary actually becomes after tax and National Insurance.
