In most commercial settings, professional carpet cleaning is far cheaper than replacement and extends the carpet's life for a fraction of the cost. Replacement only wins once the carpet is worn through, delaminating or permanently damaged. Bottom line: clean first — replace only when the carpet is physically past saving, not just dirty.
The cost gap
The numbers are stark. Professional carpet cleaning runs at roughly £2–£5/m² (budget around £4/m² for commercial premises), with a typical minimum charge near £85. New commercial carpet, supplied and fitted, costs many times that per square metre before you add uplift, disposal and downtime. For a large office floor the difference between a clean and a re-carpet is thousands of pounds — and the clean can be repeated several times before replacement ever becomes the cheaper option.
Disruption and downtime
Cleaning is done overnight or at a weekend and the area is usable again within hours once dry. Replacement means clearing furniture, lifting the old carpet, disposing of it, fitting new, and losing the space for a day or more per area. In an occupied workplace that downtime has its own cost, which the headline carpet price never shows.
What cleaning can and cannot fix
Professional cleaning removes soil, most stains, odours and allergens, and restores appearance and pile — often dramatically on a carpet that merely looks tired. What it cannot fix is physical failure: pile worn back to the backing in traffic lanes, delamination, burns, flooding damage, or a carpet simply at the end of its service life. Those are replacement cases, and honest advice will say so.
How regular cleaning extends carpet life
Carpet wears out faster when grit is left in the pile, because it abrades the fibres underfoot. A planned cleaning cycle — interim maintenance on traffic lanes plus periodic deep extraction — lifts that grit out and materially extends the carpet's usable life, deferring the far larger replacement cost. Building it into a periodic cleaning schedule is cheaper than reacting once the carpet looks ruined.
When to replace
Replace when the carpet is worn through, delaminating, contaminated beyond cleaning (flood, sewage), or when a refit is happening anyway. At that point cleaning is throwing good money after bad. Otherwise, a professional clean is almost always the first move — we will tell you honestly which case you are in rather than defaulting to the bigger job.
Carpet cleaning vs carpet replacement
| Factor | Professional cleaning | Replacement |
|---|---|---|
| Cost | ~£2–£5/m² (from ~£85 minimum) | Many times higher per m² plus uplift, disposal and downtime |
| Control | Repeatable maintenance on a schedule | One-off capital spend and refit |
| Reliability / cover | Usable within hours once dry | Space lost for a day or more per area |
| Compliance | Removes allergens and soil; supports hygiene | Fresh carpet, but only worthwhile if the old one has failed |
| Best for | Tired, soiled or stained but structurally sound carpet | Worn-through, delaminated, flood-damaged or end-of-life carpet |
