How many square metres do you actually need?
Listings sell light and lifestyle; square metres are what you live in. This gives you a working target from how many of you there are, who works from home, and how much stuff follows you around, with the official UK space standard alongside for a reality check.
Recommended floor area
50 m²
About 538 square feet. Comfortable rather than palatial: you can live in less, and plenty of Londoners do.
How it adds up
For context
Trust the floor plan, not the photos
Wide-angle lenses make small rooms look generous, so get the actual number. Ask for a floor plan with measurements, and look up the property's EPC on the gov.uk register, which states the total floor area in square metres for free. Comparing that figure against your target above tells you more than any photo gallery, and it feeds straight into our rent comparison tool if you are weighing up several flats.

Common questions
What is the minimum legal bedroom size?
For licensed HMOs in England, the statutory minimum is 6.51 square metres for a bedroom used by one adult, and 10.22 square metres for two. Councils can set higher standards but not lower. Outside HMOs there is no fixed minimum bedroom size for an ordinary single-household tenancy, though severe overcrowding is covered by separate housing law. If a listing calls 5 square metres a bedroom, it is a cupboard with ambitions.
What is the national space standard?
The Nationally Described Space Standard sets minimum gross internal areas for new homes in England, by number of bedrooms, occupants and storeys. For a one-storey, one-bedroom flat for two people the figure is 50 square metres. It applies to new buildings where the local council has adopted it, not to the existing rental stock, which is precisely why so many older conversions come in well under it. It is still the most useful yardstick a renter has.
Does floor area include hallways and storage?
On an EPC, yes. The total floor area on an Energy Performance Certificate is the whole usable internal area of the home, including hallways, landings and built-in storage, measured to the inside of the external walls. It excludes external spaces like balconies. That makes EPC figures comparable between properties, and it also means a flat with a long hallway has less liveable space than the headline number suggests.
The flats I can afford are smaller than my number. Now what?
Treat the number as a target, not a rule. A well-shaped 48 square metres with storage can live better than a badly-shaped 58. Prioritise a sensible floor plan over raw area: square rooms, real storage, a hallway that is not a third of the flat. Offsite storage from around £25 a month can absorb the boxes you open twice a year, and furniture that does two jobs (bed with drawers, table that folds) buys back more space than you would expect.
Does a bigger flat cost more to run?
Yes, roughly in proportion to the area. Heating scales with the volume of space you keep warm, so an extra 15 square metres is not just extra rent, it is extra gas every winter. Council tax bands also loosely track size and value. Our energy cost calculator takes floor area as its first input, so you can put a monthly figure on the difference between two sizes before you commit.
