Carpet tiles are the default floor for offices, salons, studios, surgeries and small shops for good reason. They are hard wearing, quick to fit, easy to replace tile by tile when something gets spilled or scuffed, and they absorb sound in a way hard flooring never will. They are also the product most often bought badly, because the tiles that look identical in a photograph can differ enormously in wear rating and backing. This guide covers what actually matters when you are specifying tiles for a working space, and how a commercial fit differs from a domestic one. We fit these regularly across Dartford, Gravesend, Bromley, Greenwich and the wider South East London and Kent area.
Wear classification: get this right first
Commercial floor coverings carry an EN 685 or EN ISO 10874 use class. For a general office you want class 32 as a minimum, class 33 for heavy commercial such as a reception, corridor or retail floor, and class 34 for very heavy use.
A domestic grade tile in a corridor will look tired within a year, and it is a false economy because the labour to lift and refit is the same as fitting the right tile once. If a supplier cannot tell you the use class, treat that as your answer.
- Class 31 or 32: private offices, meeting rooms, low traffic.
- Class 33: reception, corridors, open plan floors, retail, salons.
- Class 34: entrances, heavy retail, circulation routes in busy buildings.
- Castor chair suitable: check this separately, it is not implied by use class.
Backings and what they mean in practice
Bitumen backed tiles are the traditional heavyweight option, very stable and forgiving of a slightly imperfect subfloor. PVC backed tiles are stable and widely used in offices. Cushion backed tiles add comfort and a useful amount of sound absorption, which matters in an open plan floor or a treatment room.
Weight is a reasonable proxy for quality. A heavier tile with a dense pile and a stable backing lies flatter, resists edge curl and copes better with chair castors than a light tile at the same price point.
Tile size and laying pattern
The standard is a 500 by 500 millimetre tile. Plank formats, commonly 250 by 1000 millimetres, are increasingly popular and let you use ashlar or herringbone style layouts to break up a large floor.
Laying pattern changes both look and cost. Monolithic, where every tile faces the same way, gives the most seamless appearance but shows any pile direction error. Quarter turn, where each tile is rotated ninety degrees, hides small shade variation and is the safest choice on a large floor. Brick and ashlar layouts suit plank tiles and read as more contemporary.
- Quarter turn: most forgiving, standard for offices.
- Monolithic: cleanest look, needs careful setting out and consistent batches.
- Brick or ashlar with planks: modern, good for zoning a large open floor.
- Two tone or accent runs: a cheap way to mark circulation routes and zones.
Subfloor and adhesive
Tiles need a clean, dry, flat subfloor exactly like any other floor covering. On concrete that usually means removing old adhesive residue and applying a smoothing compound. Damp readings matter, and a screed that has not fully dried will show up later as failed adhesive.
Most commercial tiles are laid on a tackifier rather than a permanent adhesive, which holds the tile in place while still letting a single tile be lifted and replaced. Where trolleys and heavy castor traffic are involved, a full spread adhesive on entrance and circulation runs is worth the extra.
Cost and how a commercial quote is built
Budget for four things: the tile, the preparation, the tackifier or adhesive, and the labour. Preparation is the item that varies most and the one most often left out of a cheap quote.
Ask for the quote to state the tile name and use class, the square metre figure, the preparation allowed for, the laying pattern, the perimeter and threshold detail, and whether fitting is inside or outside normal hours. On refurbishment work, also confirm who is lifting and disposing of the existing floor.
Out of hours and phased fitting
The advantage of tiles is that a floor can be fitted in sections. We regularly work evenings and weekends so a business can trade or operate as normal, and on larger floors we phase the work zone by zone with desks and stock shifted across rather than cleared out entirely.
It is worth agreeing the sequence in writing beforehand, including where furniture goes at each stage and what has to be powered down. That single conversation removes most of the friction from a commercial fit.
Maintenance and keeping spares
Vacuum with a beater bar or brush head, spot clean promptly, and set a periodic low moisture extraction clean rather than soaking the floor. Entrance matting does more for the life of a commercial carpet than any other single measure.
Always order and keep a box or two of attic stock from the same batch. When a tile is damaged, a batch matched replacement is invisible, and a tile from a later run rarely is.

Frequently asked questions
How long do commercial carpet tiles last?
A correctly specified class 33 tile in an office typically gives ten years or more, with individual tiles replaced along the busiest routes rather than the whole floor.
Can tiles be laid over existing carpet tiles?
Not reliably. The old tiles and adhesive residue come up, the floor is prepared, then new tiles go down. Layering leads to movement and visible joints.
Do you fit outside working hours?
Yes. Evening and weekend fitting is normal on commercial work, and larger floors can be phased zone by zone so the space stays usable.
Are carpet tiles suitable with office chairs?
Yes, provided the tile is stated as castor chair suitable and is laid on the correct adhesive. This is a specific check rather than something to assume.
