How Much Workspace Per Person? The UK Legal Minimum and Real Sizes
Britain's legal minimum is stated as a volume, not a floor area: 11 m³ of empty space per person normally working in the room, with ceiling height counted only up to 3 m. At a typical 2.4 m ceiling that works out at about 4.6 m² of floor each; at a 3 m ceiling, 3.7 m². That is the floor of what is lawful, not a target. Of the 2,780 private rooms with a size in this catalogue, 31 are below 4.6 m² — rooms that need a high ceiling to hold even one person legally.
Why is the UK rule a volume and not an area?
Because the British rule is about air, not about desks. The Approved Code of Practice to Regulation 10 of the Workplace (Health, Safety and Welfare) Regulations 1992 sets 11 m³ per person, measured on the empty room, and caps the counted height at 3 m so that a tall warehouse does not "earn" extra people. Furniture, storage and partitions all reduce the usable volume, which is why the ACoP calls 11 m³ a minimum that may be insufficient depending on layout and the nature of the work.
The conversion catches people out. A 4 m² room with a 2.4 m ceiling is 9.6 m³ — below the minimum for one person. The same 4 m² room with a 2.75 m ceiling is exactly 11 m³. Floor area alone never answers the question.
How much space does a team actually need?
The legal floor and a workable office are different numbers. In practice UK flexible buildings allow room for circulation, storage and meeting space on top of the per-person minimum, and the listings reflect that.
| Team | Legal minimum at 2.4 m ceiling | What UK listings typically offer |
|---|---|---|
| 1 person | 4.6 m² | A small private room, from about 5 m² |
| 5 people | 23 m² | Roughly 30–50 m² |
| 10 people | 46 m² | Roughly 60–100 m² |
| 20 people | 92 m² | Roughly 120–200 m² |
The left column is a compliance test, and the right column is what a team of that size usually ends up taking. The median private room listed across the UK in this catalogue is 65 m², which sits comfortably in the range a team of six to eight would use; 300 listings fall in the 46–60 m² band.
What does the size distribution look like?
Across the 2,780 sized private rooms listed in the UK: 428 are 20 m² or under, 668 are 20–50 m², 1,100 are 50–150 m², and 584 are larger than 150 m². The ninth decile is 290 m². A UK search that assumes everything is either a cupboard or a whole floor is missing the middle, where most of the supply actually sits.
What else eats the space?
Four things stand between the 4.6 m² legal figure and a room a UK team can actually work in:
- Circulation. Doors, walkways and the space to push a chair back are not usable desk area but are inside your m².
- Storage. Cabinets and coats reduce the empty volume the regulation measures.
- Meeting space. In a serviced building this usually sits outside your room and is charged on use — which is why a serviced room can be smaller than a conventional office for the same headcount.
- Growth. A room sized exactly for today's headcount is a room you outgrow before the term ends.
Does the rule apply to coworking desks?
The regulation applies to the workroom, so it is the operator's responsibility for the whole coworking floor rather than something you calculate for your seat. That is one practical reason desk listings in this catalogue carry no floor area: a desk is a seat in someone else's room, and publishing a per-seat m² figure would describe an allocation, not a space you control. Across the 502 UK buildings selling desks, what varies is how many people share the room and what else is on the floor.
Where to look
Browse serviced offices across the UK — 2,898 rooms in 548 buildings from £145 a month, filterable by size — or coworking desks from £118 if a seat is enough. Trade-offs between a private room inside a coworking building and a room of your own are covered in private offices in coworking buildings. Enquiring costs the tenant nothing.
