A floor socket puts power in the middle of a room without a cable running to the wall — and the single most important number on it is IP20, which means indoors, dry, and never anywhere it could be washed or flooded.
Get that right and they solve a problem nothing else does: the sofa in the middle of an open-plan room, the boardroom table, the island with a laptop on it.
Here is the difference between the types, and what to check before you cut a hole in a floor.
1. Floor socket or pop-up — which is which
A floor socket sits flush in the floor behind a hinged or spring-loaded lid. Closed, it is a flat plate you walk over. Open it, plug in, and the lid sits back against the flex.
A modular floor plate is the same idea built to take Euro modules, so you choose what goes in it — sockets, data, or a mix — rather than accepting a fixed configuration.
Both are commonly called pop-up sockets. The distinction that matters is fixed outlet versus modular, because it decides whether you can change your mind later.
Knightsbridge FPR7UMB — 13A 1G Unswitched Floor Socket, Matt Black, IP20, 230V, 86mm x 94.5mm. The straightforward fixed floor socket at 86mm x 94.5mm. Unswitched, because a switch you have to kneel on the floor to reach is a switch nobody uses.
2. Where they earn their keep
Open-plan living rooms where the sofa floats. Kitchen islands. Home offices with a desk away from the walls. Boardrooms and meeting rooms, which is where most people first meet one.
The test is simple: if the alternative is a cable taped down across a walkway, a floor socket pays for itself the first time nobody trips over it.
Where they do not belong: bathrooms, kitchens at floor level where mopping happens, conservatory floors that get wet, garages, and anywhere outdoors. IP20 means protected against fingers and nothing else.
Trade Tip: think about the vacuum cleaner before you choose a position. A floor socket in a traffic route gets a hoover wheel over it twice a week for twenty years. Under the edge of a sofa or beside a table leg, it gets left alone — and the lid mechanism is the part that eventually gives up.
3. Modular plates: build what you need
The modular versions take standard Euro modules, so one plate can hold power and data together — which is usually what a desk or a boardroom table actually wants.
Knightsbridge FPF4GBC — 4G Modular Floor Plate, Brushed Chrome, Ultra Low Profile, IP20, Accepts Euro Modules, 144x94.5mm. Four module positions in a 144 x 94.5mm plate. Fill it with sockets, or split it between power and network outlets, and change the mix later without lifting the plate out of the floor.
Knightsbridge FPF2GMW — 2G Modular Floor Plate, Matt White, Euro Module Compatible, Ultra Low Profile Design, Spring Loaded Lid. The two-module version with a spring-loaded lid, in matt white for light floors. Two positions is usually enough beside a sofa: one socket, one data.
4. Depth is the thing that stops the job
The plate is low profile — the modular plates here are 16.2mm deep at the plate itself. What sits underneath is not.
Below the plate you need the back box, the accessory body and the cable, and all of that has to fit inside the floor build-up without fouling a joist. In a suspended timber floor that is usually fine. In a solid floor with 65mm of screed over insulation, it is a conversation to have before anybody picks up a disc cutter.
Measure the depth available at the exact spot, not somewhere nearby. Joists do not run where you would like them to.
Trade Tip: mark the position with the furniture in the room, not an empty one. Every floor socket that ended up under a sofa leg was positioned in an empty room with a tape measure and a clear head. Put the furniture where it is going first, then mark the floor.
Knightsbridge FPR7UBCW — 13A Unswitched Floor Socket, Brushed Chrome Finish, 1 Gang, IP20, Spring Loaded Cover, 230V. Brushed chrome with a spring-loaded cover, which shuts itself when the plug comes out rather than waiting for somebody to close it.
5. Finish, and what it will look like in five years
Brushed chrome and matt black both hide scuffs better than polished finishes, which matters on something that gets walked on. Match the floor rather than the switch plates — the socket sits in the floor and is seen against it.
For the cable coming up into it, and how it relates to the rest of the room's power, the fused spur guide covers when a spur is the right way to feed an outlying accessory.
Summary: floor and pop-up sockets
| Consideration | What to do |
|---|---|
| Location | Indoors and dry only — IP20 means no bathrooms, no outdoors, no wet floors |
| Fixed or modular | Modular if you might want data as well, or want to change the mix later |
| Position | Out of the main traffic route; mark it with the furniture in place |
| Depth | Check the floor build-up at that exact spot before cutting |
| Switching | Unswitched — nobody kneels down to flick a floor switch |

Floor socket FAQs
Are floor sockets safe?
Yes, fitted in the right place. They are IP20 — protected against fingers, not against water — so they belong in dry indoor floors only. Never fit one in a bathroom, a wet room, a garage floor or outdoors.
Can you put a floor socket in a concrete floor?
Often yes, but the depth available underneath decides it. You need room for the back box, the accessory and the cable within the screed or build-up. Check the actual depth at the position you want before committing.
What is the difference between a floor socket and a pop-up socket?
In everyday use, very little — both describe a socket that sits flush in the floor behind a lid. The distinction worth caring about is fixed outlet versus modular plate: the modular version lets you choose and later change what sits in it.
