Daily, weekly, or somewhere in between? The honest answer depends on how many people use the space, what they do in it, and which areas you are talking about — because not everything needs the same frequency.
Most businesses arrive at their cleaning schedule by accident. Someone set it up years ago, headcount changed, the office moved, and the contract carried on unchanged. The result is usually money spent in the wrong places: daily vacuuming of a room nobody uses, and a kitchen that gets attention once a week when twenty people eat in it.
It is worth working out from first principles.
Start with occupancy, not office size
Square footage matters far less than how many people are in the building and how long they stay. A 2,000 sq ft office with six people needs a very different schedule from the same space with twenty-five.
As a rough guide:
- Under 10 people — two to three visits a week is usually enough, with washrooms the deciding factor
- 10 to 30 people — daily or near-daily for washrooms and kitchen, two to three times a week for general areas
- 30+ people — daily throughout, with some businesses adding a midday washroom check
- Client-facing premises — daily regardless of headcount, because reception is doing a job beyond hygiene
Hybrid working has complicated this. If your office is full on Tuesday to Thursday and nearly empty on Monday and Friday, a flat five-day schedule is wasting two days of cleaning. Several of our clients moved to a three-day schedule matched to their busy days and put the saving into a deeper clean each visit.
Different areas, different frequencies
This is where most schedules go wrong — treating the whole office as one thing.
Daily, in almost any office
- Washrooms: cleaned, sanitised and restocked
- Kitchen and break-out areas, including the fridge exterior and microwave
- Bins emptied
- Reception and entrance if you have visitors
- Door handles, light switches and shared touch points
Two or three times a week
- Vacuuming through general office areas
- Hard floors mopped
- Desk surfaces where policy allows
- Meeting rooms, or after each significant use
Weekly or fortnightly
- Internal glass and partitions
- Skirting boards and low-level dusting
- Kitchen appliances cleaned inside
- Storage and print areas
Quarterly or twice yearly
- Carpet deep clean — more often in high-traffic entrances
- High-level dusting: light fittings, vents, tops of cupboards
- Upholstery and soft seating
- Full washroom descale
The areas businesses consistently underestimate
Kitchens. Shared office kitchens are used more heavily than domestic ones and cleaned less thoroughly. The microwave, the fridge and the sink area are where complaints start.
Carpets. Office carpet gets walked on constantly and vacuuming only lifts surface dirt. The grit that stays in the pile is abrasive, and it is what wears carpet out — which makes periodic professional carpet cleaning a maintenance cost rather than a cosmetic one. Replacing office carpet is considerably more expensive than cleaning it.
Touch points. Door handles, kitchen taps, shared keyboards, lift buttons and stair rails. These take minutes and have more effect on how much illness spreads through an office than anything else on the list.
Anything above eye level. Nobody notices dust on top of a cupboard until a client does.
Does cleaning frequency actually affect sickness absence?
Reasonably, yes — though it is worth being careful about how strongly anyone claims this. Respiratory and gastrointestinal infections spread through shared surfaces and shared air, and regular cleaning of high-touch surfaces reduces the surface route. Ventilation, vaccination and people staying home when unwell all matter too.
What we can say from experience is that the offices that increase washroom and touch-point frequency over winter tend to report fewer problems than those that do not. Treat it as one useful measure among several rather than a guarantee.
What about your legal obligations?
UK workplace regulations require employers to keep workplaces, furniture and fittings clean, to remove waste regularly, and to provide clean and adequately stocked sanitary facilities. The wording is about outcome rather than a set schedule — there is no legally mandated number of visits per week.
In practice this means you need a schedule that demonstrably keeps the workplace clean and washrooms properly maintained. If your current arrangement cannot manage that, it is not adequate regardless of what it costs.
This is general guidance rather than legal advice — if you have specific obligations in a regulated sector, check them properly.
Getting the schedule right
A few things worth doing:
- Count your actual occupancy, not your desk count. Hybrid patterns change the answer.
- Separate the areas. Washrooms and kitchens on one frequency, general office on another.
- Build in periodic deep work rather than hoping the regular visits cover it. A quarterly deep clean catches what routine cleaning cannot.
- Review it annually. Headcount and working patterns move; schedules rarely follow.
- Ask your cleaners what they are seeing. They know which areas are struggling before you do.
Talk to us
We have been cleaning commercial premises across Cambridgeshire for over 20 years — offices, retail units, schools, healthcare and industrial premises — on daily, weekly and fortnightly contracts scheduled around opening hours.
Every contract is quoted individually, because a dental practice and a warehouse genuinely do need different things. Have a look at our commercial cleaning services or request a free quote. We cover Cambridge, Ely, St Neots, Huntingdon, St Ives, Cambourne, Royston, Newmarket and the surrounding area.
How often should office washrooms be cleaned?
Daily as a minimum in any office with regular occupancy, and busier premises often add a midday check for restocking and a quick sanitise. Washrooms are the area staff and visitors judge a building by, and the one most likely to generate complaints.
Should offices be cleaned during or outside working hours?
Most commercial contracts run early morning or evening so the premises are clear. It is less disruptive and cleaners work faster without navigating people. Retail and hospitality often prefer after closing for the same reason.
How often should office carpets be professionally cleaned?
Every six to twelve months for general office areas, and more frequently for entrances and main walkways where grit is walked in. It is worth treating as maintenance — trapped grit is abrasive and shortens the life of the carpet.
Do we need a long contract?
No. We work on regular contracts, ad-hoc bookings and one-off cleans. Plenty of clients start with a single deep clean and move to a regular schedule once they see the standard.
Which areas do you cover?
Cambridge, Ely, St Neots, Huntingdon, St Ives, Cambourne, Royston, Newmarket, Sawston, Histon, Waterbeach, Great Shelford and the surrounding villages. If your postcode starts CB or PE, just ask.
