Office Carpet Cleaning
Prices in London 2026.
Transparent per m² pricing, what affects the cost, and how a maintenance plan compares to ad hoc booking. From a London specialist.
If you manage a commercial building in London, you have probably asked this question at least once: how much should we be paying to have the office carpets professionally cleaned? This guide explains exactly how commercial carpet cleaning is priced in London, what factors affect the cost, and how to compare quotes fairly. Written by Prestige Commercial — a specialist office carpet cleaning company based in Marylebone W1, trusted by Harrods, Selfridges, NHS, Octopus Energy and Citibank.
How commercial carpet cleaning is priced in London
Unlike domestic carpet cleaning — which is often charged per room — professional commercial carpet cleaning is almost always priced per square metre. This is more transparent for FM teams because costs scale predictably with the size of your space.
Typical London commercial carpet cleaning rates
| Office size | Ad hoc rate (per m²) | What to expect |
|---|---|---|
| Up to 300m² | £3.50–£4.00/m² | Minimum call-out charges may apply |
| 301–600m² | £3.00–£3.50/m² | Standard mid-size office rate |
| 601–1,000m² | £2.50–£3.00/m² | Volume discount applies |
| 1,000m²+ | £2.00–£2.50/m² | Bespoke quote recommended |
All prices exclude VAT at 20%. These are ad hoc rates — a one-off clean with no contract in place. Planned maintenance programmes reduce the per-m² rate by 12–25%.
What affects the cost of office carpet cleaning in London?
1. Size of the carpeted area
The single biggest factor. Larger offices cost more in total but less per m², because the fixed costs of mobilisation, travel and set-up are spread across more carpet.
2. Cleaning method
Low-moisture encapsulation (VLM)
The preferred method for occupied office buildings. Uses an orbital cleaning system with minimal water, allowing carpets to be walked on within the hour. Ideal for out-of-hours cleans with zero disruption. This is the method Prestige Commercial uses for all office carpet tile work.
Hot water extraction (steam cleaning)
A deeper clean that requires carpets to be left for several hours to dry. Better suited to heavily soiled carpets or end-of-tenancy deep cleans. Not ideal for occupied buildings during trading hours.
3. Condition of the carpet
Heavily soiled carpets, or carpets that have not been professionally cleaned in several years, take longer and may require pre-treatment. A competent contractor will flag this at the site survey stage — not after the job.
4. Access and out-of-hours requirements
Out-of-hours working — evenings, weekends, early mornings — is standard practice for commercial carpet cleaning in Central London. At Prestige Commercial we include out-of-hours scheduling at no additional charge. Not all contractors do, so it is worth asking.
5. Central London location
Operating in Zones 1 and 2 adds costs for contractors: congestion charges, parking, and travel time. These are sometimes itemised separately; sometimes absorbed into the per-m² rate. Always ask before you agree a quote.
Ad hoc cleaning vs. a planned maintenance programme
This is the question most FM managers do not ask until they have been caught out by an emergency spill or a carpet that has deteriorated faster than expected.
Ad hoc cleaning means calling a contractor when the carpet needs attention. The advantage is flexibility. The disadvantage is cost — you pay the full one-off rate each time, you have to remember to book, and you have no priority call-out arrangement if something goes wrong before a board meeting.
A planned maintenance programme means agreeing a schedule of professional cleans in advance, at a reduced per-m² rate, with emergency call-outs included. The carpet is maintained to a consistent standard throughout the year, the budget is predictable, and the administration is handled by the contractor.
Annual cost comparison — 500m² office, 4 cleans per year
| Approach | Annual cost (approx.) | Call-outs | Admin |
|---|---|---|---|
| Ad hoc | £6,500–£7,500 | Charged separately (min. £300/visit) | Your responsibility to book |
| 12-month plan | £5,500–£6,200 | 3 per year included | Scheduled by us |
| 24-month plan | £5,000–£5,700 | 6 per year included | Scheduled by us |
| 36-month plan | £4,600–£5,200 | Unlimited | Scheduled by us |

How to compare commercial carpet cleaning quotes fairly
When requesting quotes from London carpet cleaning companies, ask the following:
- Is the rate per m² or per room? Per m² is more transparent for commercial spaces.
- What cleaning method do you use? Low-moisture is preferable for occupied offices.
- Are out-of-hours cleans included at no extra charge?
- What is the minimum call-out fee for emergencies?
- Are you NCCA-accredited and fully insured?
- Can you provide photo reports after each clean?
The cheapest quote is rarely the best value. A company that uses hot water extraction in an occupied office building, or cannot provide RAMS documentation for a managed estate, will create problems that cost more than the saving.
