Your Practical Guide to Commercial Office Cleaning in the UK
Commercial office cleaning typically covers desks, bins, floors, kitchens, and washrooms daily, with windows and deeper tasks scheduled monthly. How often you need it depends on footfall and office size, and UK contracts generally range from £300 to £5,000+ a month depending on scope. Here's what to check before you sign.
What's Included in Commercial Office Cleaning
Standard office cleaning contracts are broken down into daily, weekly, and monthly tasks. Use this as a starting point to compare against any quote you're given:
| Task | Typical Frequency |
|---|---|
| Desks, surfaces & high-touch points | Daily |
| Bins & waste removal | Daily |
| Floors & vacuuming | Daily to 2-3x weekly |
| Kitchen & break room | Daily |
| Washrooms | Daily |
| Windows & glass | Monthly |
How Often Should an Office Be Cleaned?
Higher-footfall offices — reception areas, shared kitchens, washrooms — generally need daily attention regardless of overall office size. Smaller or lower-footfall offices can often move to 2-3 visits a week without a noticeable drop in standards. Daily cleaning also tends to work out more cost-effective per visit than infrequent cleaning, since travel and set-up costs are spread across more visits rather than concentrated into one longer clean.
What Does It Cost?
UK office cleaning contracts typically range from £300 to £5,000+ a month, depending on floor area, frequency, and scope. For a full breakdown by property type, see our commercial cleaning cost guide.
In-House vs Outsourced Cleaning
Keeping cleaning in-house avoids a contractor relationship but usually means managing staffing, supplies, and cover for absences yourself. Outsourcing shifts that admin burden onto the provider and typically includes insurance and trained cover as standard. For the fuller productivity and first-impression case for outsourcing, see our guide to the benefits of commercial cleaning services.
Certifications and Compliance to Look For
Certifications aren't just badges on a website — each one verifies a different part of a cleaning company's operation:
| Certification | What It Verifies |
|---|---|
| BICSc | Individual operatives trained and assessed to a recognised standard |
| ISO 9001 / 14001 | Documented quality management and environmental process |
| COSHH compliance | Safe handling and storage of cleaning chemicals — a legal requirement |
| Public liability insurance | Financial cover if something goes wrong on site — UK contracts typically expect £5 million minimum |
Ask for the company's BICSc membership number and ISO certificate number directly, rather than trusting a logo alone — genuine providers give these without hesitation.

Choosing a Commercial Cleaning Provider
Before signing a commercial cleaning contract, it's worth asking:
- Can you provide your BICSc membership number and current insurance certificate?
- Do you hold ISO 9001 or 14001, and can I see the certificate number?
- How is your team trained on COSHH-regulated products?
- What's your approach to sustainability questions in tenders?
- How is cleaning scheduled around our office's actual footfall?
A provider who answers these specifically, rather than with general reassurance, is usually the safer choice. Ready to discuss a compliant contract for your site? See our commercial cleaning service for a free site assessment.
Commercial Office Cleaning UK FAQs
How often should an office be cleaned?
Most UK offices need daily cleaning of busy areas like kitchens, washrooms and desks. Lighter jobs like window cleaning can be done monthly. A smaller office with low footfall can often drop to 2 or 3 visits a week without any problem, which brings the cost down.
What's included in a standard office cleaning contract?
A standard contract covers desks and surfaces, bins, floors, the kitchen or break room and washrooms on a daily or near-daily basis. Windows, carpets and deep cleaning are usually scheduled monthly or quarterly. Check the specification lists each task and how often it happens, so nothing is left to guesswork.
Is daily or weekly cleaning cheaper long-term?
Daily cleaning often costs less per visit than occasional cleaning, because travel, setup and admin costs are spread across more visits. Over a year, though, weekly cleaning usually costs less in total. It suits smaller offices with low footfall, where daily visits would mean paying for cleaning that isn't needed.
Do I need a certified provider for a small office?
It isn't a legal requirement. Even so, it's worth checking for BICSc-trained staff and valid public liability insurance at any size of office. Both protect you if something goes wrong on site, and a small office can suffer just as much from a damaged laptop or a flooded kitchen.
