You never regret one socket too many — always one too few, discovered the day an extension lead crosses the living room. The standard sets minimums per room: here they are, with mounting heights.
Minimums per room (NF C 15-100)
| Room | Min. 16 A sockets | Other requirements |
|---|---|---|
| Living room | 1 per 4 m², minimum 5 (7 if > 28 m²) | 1 ceiling light + network socket |
| Bedroom | 3 | 1 lighting point + network socket advised |
| Kitchen | 6 incl. 4 above the worktop | + dedicated circuits; none above the sink or hob |
| Bathroom | 1 (outside the zones) | see the safety zones |
| Hallway, WC, utility | 1 advised | 1 lighting point |
| Outdoors | as needed | IP44 minimum, on a 30 mA RCD |
Dedicated circuits: 1 appliance = 1 circuit
- At least 3 dedicated 20 A circuits per dwelling (washing machine, oven, dishwasher…), plus the 32 A hob circuit.
- Tumble dryer, freezer, water heater: dedicated too, whenever present.

Every socket is decided before the walls close — ten times cheaper than after. The exact moment in the project: phase 2, the services.
