Small Office Cleaning: What the Law Requires
The Workplace Regulations 1992 put real duties on employers for cleanliness, waste and washrooms. What a small office needs, how often, and who enforces it.

In short
UK employers have a legal duty on cleanliness. The Workplace (Health, Safety and Welfare) Regulations 1992 require every workplace and the furniture in it to be kept sufficiently clean, waste to be held in suitable receptacles, and toilets and washing facilities to be kept clean and stocked. No cleaning frequency is set in law, so the schedule is yours to choose and justify.
Most people running a small business assume workplace cleaning is a matter of taste and budget. It is partly a legal duty. If you employ anyone, the Workplace (Health, Safety and Welfare) Regulations 1992 apply to your premises, and three of the things they cover are cleanliness, waste and washing facilities.
That is worth knowing before you write a scope of works, because it changes what belongs in the contract and what you can safely leave out.
What the regulations actually require
Regulation 9: cleanliness and waste
Regulation 9 is short. It applies to the workplace and to its furniture, furnishings and fittings alike, and the standard it sets for all of them is that they are kept sufficiently clean. The surfaces of floors, walls and ceilings inside a building must be capable of being kept sufficiently clean. Waste must not be allowed to accumulate except in suitable receptacles.
Regulations 20 and 21: the washroom
Toilets must be suitable, sufficient and readily accessible, and both they and the rooms containing them must be kept in a clean and orderly condition. Washing facilities must include running hot and cold or warm water, soap or another cleaning agent, and a means of drying hands.
HSE’s welfare leaflet makes this a maintenance duty rather than a one-off. The facilities have to stay clean and in good condition, there has to be enough soap and toilet paper at all times, and the leaflet expects a working system behind that rather than good intentions. A cleaner who visits twice a week does not by itself satisfy that if the soap runs out on a Wednesday.
How many toilets a small office needs
There is also a numbers question, and here HSE does give a figure.
1 each for 1 to 5 people
Toilets and washbasins
Two of each once you are between 6 and 25, based on the maximum likely to be on site at one time rather than the headcount on the payroll.
What the law does not say
It does not say how often, and it does not leave the question wide open either. The Approved Code of Practice to the 1992 Regulations, published by HSE as L24, asks for regular cleaning so that dirt and refuse do not accumulate, and for spillages and deposits to be removed as soon as possible. What it declines to set is an interval. How often you clean, and to what standard, is tied to the nature of the business.
That is a real freedom and a real responsibility. Nobody can tell you that you are legally required to have a cleaner three times a week, or that you must take one on directly rather than use a cleaning company. Equally, nobody will accept “we have a cleaner” as an answer if the kitchen is unusable.
A realistic frequency for a small workplace
For a typical suite of ten to twenty desks in Canary Wharf or Stratford, the office cleaning schedule that holds up looks like this.
| How often | What that realistically keeps on top of |
|---|---|
| Daily or each visit | Washrooms in full, consumables restocked, kitchen surfaces and sink, bins emptied and separated, entrance matting and the glass by the door |
| Two or three times a week | Vacuuming of main routes and desk areas, hard floor mopping, meeting rooms reset |
| Weekly | All floor area including under desks, skirtings, internal glass, fridge front and handles, kettle and coffee machine exterior |
| Monthly | Fridge cleared and cleaned inside, microwave interior, high dusting, vents and light fittings, chair bases and castors |
| Quarterly or twice a year | Carpet extraction, upholstered chairs, window interiors, deep clean of kitchen cupboards |
Where to adjust upwards
Adjust upwards for anything with skin contact or food. A treatment room in Whitechapel or a barber’s chair in Poplar sits in a different category to a quiet accountancy office.
In hours or out of hours
Why out of hours usually wins
Out of hours is usually the right answer for offices. Floors can be done in one pass, kitchens can be stripped back, and nobody is moving a laptop out of the way. It also keeps the cleaning off the working day, which matters in a small suite where the noise has nowhere to go.
When a daytime visit earns its place
In hours makes more sense where the dirt is generated by people arriving. Salons, clinics, studios and anywhere with a public washroom benefit from a short midday visit that restocks, wipes touch points and clears the kitchen, with the main clean still done in the evening.
Access is the practical constraint
Many serviced buildings around the Isle of Dogs restrict contractor access after a certain hour, and some require a signed in fob. Sort that out before agreeing a schedule rather than after.
What tends to get skipped
- Shared keyboards, mice and desk phones. Hot desking makes these the most handled and least cleaned objects in the room.
- The fridge. Almost never in the specification, and the single most common source of complaints in a shared kitchen.
- Washroom consumables mid-week. A restock on Monday is not a system if the dispenser is empty by Thursday.
- Entrance matting. It traps the grit that then grinds into the carpet everywhere else. Vacuuming it properly saves the floor behind it.
- Waste separation. Bins get emptied into one bag, which quietly undoes the recycling arrangement you are paying for.
Waste is now a separate duty
The trigger is headcount. Any workplace in England at or above 10 full-time equivalent employees has, since 31 March 2025, been required to keep dry recyclables, meaning plastic, metal, glass, paper and card, and food waste as separate streams. Food waste applies even where there is no kitchen. Businesses with fewer than 10 full-time equivalent staff have until 31 March 2027.
This matters for cleaning because the person emptying the bins is the person who either keeps the separation intact or destroys it. If your cleaning brief does not name the streams, assume it is not happening.
If you rent a serviced suite
Plenty of small firms in East London occupy a floor or a room in a managed building where the landlord cleans the common parts and recovers the cost through a service charge that pays for communal cleaning. That is fine, and the Approved Code of Practice allows facilities to be provided by someone else. It also says those facilities should still meet the standard and be available at all times when workers are expected to be there.
What we would say honestly
Nobody from the council is likely to arrive unannounced at a five-person studio. Enforcement for an office in privately occupied premises sits with the local authority rather than HSE, and it is mostly complaint driven. The reason to get this right is not inspection. It is that the washroom and the kitchen are the two things staff judge a small employer on, and both are cheap to keep right and expensive to recover once people have stopped using them.
HSE puts the test better than we could: would you be happy to use the welfare facilities you provide for your employees?
The numbers, and where they come from
- Cleanliness is a legal duty
- Regulation 9 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires every workplace, and the furniture, furnishings and fittings in it, to be kept sufficiently clean.

- No frequency is set in law
- HSE's Approved Code of Practice L24 says the frequency of cleaning and the standard of cleanliness depend on the nature of the business, so no fixed interval is written into the regulations.

- Washrooms must stay stocked
- HSE guidance INDG293 says employers must keep welfare facilities clean and in good condition, with an adequate supply of toilet paper and soap at all times, maintained by an effective system.

- Toilets and washbasins
- HSE's table gives one toilet and one washbasin for 1 to 5 people at work, and two of each for 6 to 25, counted on the maximum likely to be present at any one time.

- Waste separation
- Since 31 March 2025, workplaces in England with 10 or more full-time equivalent employees must separate dry recyclables and food waste. Micro-firms have until 31 March 2027.

- Who enforces an office
- Office activities, retail and catering are Schedule 1 activities under the Health and Safety (Enforcing Authority) Regulations 1998, so the local council is the enforcing authority, not HSE.

Common advice that is wrong
- false
“The regulations set a minimum cleaning frequency for offices.”
Regulation 9 asks only for a workplace kept sufficiently clean. HSE's Approved Code of Practice ties frequency and standard to the nature of the business, so the schedule is yours to set.
They do not. Regulation 9 asks for a workplace that is sufficiently clean and says nothing about how often. Paragraph 90 of HSE's Approved Code of Practice and guidance (L24) then ties both how often you clean, and how clean is clean enough, to the kind of business you run. That is deliberately open, because a two-person design studio and a walk-in clinic have very different needs. It also means the schedule is yours to set and yours to defend if anyone asks.

- partly true
“Our building manager cleans the toilets, so it is not my responsibility.”
The facilities your staff use have to meet the Code and be available whenever they might be at work, whoever actually cleans them.
Someone else can do the work. Paragraph 190 of HSE's Approved Code of Practice (L24) says that where facilities are provided by someone else, such as the owner of the building, they should still meet the Code and be available at all times when workers might be expected to be in the workplace. The owner carries duties for the parts they control, and you carry the duty to make sure what your staff use complies. If the shared washroom is out of soap by Tuesday afternoon, that is your problem to raise.

- false
“HSE would be the ones to turn up if there were a problem in our office.”
The borough's environmental health team is the enforcing authority for a private-sector office. HSE keeps factories, farms, building sites and government premises.
For most offices, shops, salons and restaurants, the enforcing authority is the local council, not HSE. The Health and Safety (Enforcing Authority) Regulations 1998 put office activities in Schedule 1, which hands enforcement to the borough. HSE's own list keeps factories, farms, building sites and government offices, and sends offices, shops, restaurants and leisure premises to local authority environmental health. In practice that is an officer from Tower Hamlets or Newham, not a national inspector.

What we see on the job
We clean small offices as well as homes, and for a business the thing that actually matters is not the checklist, it is whether somebody turns up. We have never no-showed on a job. If we say nine, we are there at nine, and if something does come up you get a call before the slot rather than after it. We work early mornings, evenings or weekends around your hours, and you get the same team each time instead of whoever an agency has spare, which counts for more than usual when the office is empty and they are holding your keys.
Common questions
What does the law actually say about office cleanliness?
Regulation 9 of the Workplace (Health, Safety and Welfare) Regulations 1992 sets one standard, sufficiently clean, and applies it to the workplace and to its furniture, furnishings and fittings. Floors, walls and ceilings have to be capable of being kept clean, and waste must not be allowed to build up except in suitable receptacles. It is a duty about outcome, not about method.
How many toilets does a small office need?
HSE's guidance gives one toilet and one washbasin where 1 to 5 people are at work, and two of each for 6 to 25. The count is based on the maximum number likely to be in the workplace at one time, so visitors and shift overlap matter. Each must be kept clean and supplied with soap and a means of drying hands.
Do we have to separate food waste in a small office?
Yes, and the only question is when. Since 31 March 2025 the rule has applied in England to any workplace with 10 or more full-time equivalent employees, and having no kitchen or producing very little food waste does not exempt you. Businesses below 10 full-time equivalents get until 31 March 2027.
Is it better to clean out of hours or during the day?
Out of hours is usually better for offices, because floors, kitchens and washrooms can be done properly without working around people. Daytime cover suits salons, clinics and busy reception areas where washrooms and touch points need attention through the day. Many small workplaces use an evening clean plus a short midday check.
Who checks whether our workplace is clean enough?
For offices, shops and similar premises, the enforcing authority is the local council's environmental health team rather than HSE. Most contact starts with a complaint from a worker or a member of the public, so the practical test is whether your own staff would be happy using the washroom and the kitchen.
What is most often missed in a small office clean?
Shared keyboards, phones and hot desks, the inside of the fridge and the microwave, washroom consumables running out mid-week, the entrance matting that holds the grit tracked in from the street, and waste bins that are emptied but not separated correctly. None of it is difficult, and all of it is easy to leave out of a scope of works.
