Why School Cleaning Standards Matter More Than You Think
Keeping a school clean is not simply a matter of appearances. For the thousands of children, teachers, and support staff who occupy school buildings every day, the standard of cleaning directly affects health, wellbeing, and even academic performance. Research consistently links cleaner learning environments to lower rates of absenteeism and fewer outbreaks of common illnesses such as norovirus and influenza.
For school business managers and facility leads across London and the South East, understanding what constitutes an acceptable cleaning standard is essential — not just for the health of pupils and staff, but to satisfy regulatory expectations from bodies like Ofsted. In this guide, we break down the key standards, regulations, and best practices that every school should have in place.
The Regulatory Landscape for School Cleaning
Unlike some industries, there is no single piece of legislation that sets out prescriptive cleaning frequencies for schools. Instead, school cleaning obligations are drawn from several overlapping regulations and guidance documents.
Workplace (Health, Safety and Welfare) Regulations 1992
These regulations require that workplaces — including schools — are kept in a clean condition. Floors, walls, ceilings, and furnishings must be capable of being kept sufficiently clean. Waste materials must not be allowed to accumulate, and surfaces must be cleaned at suitable intervals.
Education (School Premises) Regulations 1999
This legislation sets minimum standards for school premises, including requirements for washroom facilities, ventilation, and the overall condition of buildings. Washing facilities must have soap, both hot and cold running water, and towels or hand dryers, and must be kept in a clean and well-maintained state.
COSHH Regulations 2002
The Control of Substances Hazardous to Health regulations are particularly important in schools, where cleaning chemicals must be managed with extra care around children. Every cleaning product used on school premises requires a risk assessment. Products must be stored in locked cupboards, clearly labelled, and accompanied by Safety Data Sheets (SDS) from the manufacturer. Staff who use these products must receive appropriate COSHH training.
This applies whether cleaning is carried out by in-house staff or a contracted cleaning provider. In either case, the school retains overall responsibility for ensuring compliance.
Keeping Children Safe in Education (KCSIE)
Any cleaning operative who works unsupervised in areas where children are or could be present requires an enhanced DBS check. This is not optional — it is a legal safeguarding requirement. Schools must ensure that their cleaning contractor has robust vetting procedures in place and can provide evidence of DBS clearance for all staff deployed to the site.
What Ofsted Looks for Regarding Cleanliness
Ofsted does not inspect cleaning as a standalone category, but hygiene and premises condition form part of how inspectors assess whether a school provides a safe and suitable environment. Under the Education Inspection Framework, inspectors consider the overall environment and the extent to which it supports pupil wellbeing.
In practice, inspectors pay attention to several areas. The general cleanliness and condition of surfaces throughout the building is noted, as is odour control and ventilation. High-touch surfaces such as door handles, light switches, and handrails are checked for evidence of regular cleaning. Dining areas and food preparation spaces are assessed for hygiene standards, and washrooms receive particular scrutiny — they should be clean, well-stocked with soap and paper towels, and free from unpleasant odours.
Importantly, Ofsted is looking for evidence that cleaning is managed as a routine, systematic process rather than a last-minute reaction to an upcoming inspection. A well-documented cleaning schedule, regular audits, and clear accountability structures all demonstrate good practice.
Building a School Cleaning Schedule
An effective school cleaning programme should be structured around three tiers: daily tasks, weekly tasks, and periodic deep cleans. Here is what a comprehensive schedule typically includes.
Daily Cleaning Tasks
- Vacuuming or sweeping all classrooms, corridors, and communal areas
- Mopping hard floors in kitchens, dining halls, and washrooms
- Cleaning and disinfecting all washroom fixtures including toilets, sinks, and taps
- Wiping down high-touch surfaces — door handles, light switches, handrails, and shared equipment
- Emptying all bins and replacing liners
- Spot-cleaning spillages and marks on floors and walls
- Restocking soap dispensers, paper towels, and toilet rolls
Weekly Cleaning Tasks
- Thorough dusting of shelves, windowsills, radiators, and ledges
- Cleaning internal glass panels and low-level windows
- Vacuuming upholstered furniture and soft furnishings
- Deep cleaning of kitchen and food preparation areas
- Cleaning computer screens, keyboards, and shared IT equipment
- Polishing or buffing hard floor surfaces in high-traffic areas
Periodic and Deep Cleaning
- Professional carpet cleaning — ideally at least twice per year, typically during half-term breaks
- Hard floor stripping, sealing, and repolishing
- External window cleaning — quarterly or termly
- Deep cleaning of sports halls, changing rooms, and PE equipment
- High-level dusting including ceiling vents, light fittings, and high shelving
- Full sanitisation of soft play areas, sensory rooms, and early years resources
School holidays provide the ideal window for deep cleaning. Planning these tasks around the academic calendar ensures minimal disruption whilst keeping the premises in excellent condition year-round.
Special Considerations for Nurseries and Early Years Settings
Nurseries and early years provisions within schools demand an even higher standard of cleanliness. Young children are more susceptible to infection and are far more likely to put objects in their mouths or come into close physical contact with surfaces and each other.
Under the Early Years Foundation Stage (EYFS) statutory framework, providers must ensure that premises are fit for purpose and suitable for the age of children cared for. In practical terms, this means more frequent cleaning throughout the day — not just at the end of sessions. Toys and resources that are mouthed should be cleaned between uses. Changing areas must be cleaned after every use. Meal tables and high chairs must be sanitised before and after eating.
Cleaning products used in early years settings must be carefully selected. Ideally, they should be fragrance-free, non-toxic where possible, and always stored well out of reach of children. Any switch to new products should be reflected in updated COSHH risk assessments.
Choosing Between In-House and Contracted Cleaning
Schools broadly have two options for managing their cleaning: employing staff directly or engaging a specialist school cleaning contractor. Each approach has its merits, and the right choice depends on the school's size, budget, and the complexity of its premises.
In-house cleaning gives the school direct control over staffing, schedules, and standards. However, it also means taking on responsibility for recruitment, training, equipment procurement, COSHH compliance, and cover arrangements for staff absence.
A professional cleaning contractor brings expertise, scalability, and established systems for quality assurance. The best contractors will provide trained, DBS-checked staff, supply all equipment and products, manage COSHH documentation, and conduct regular audits against an agreed specification. For multi-academy trusts and larger school estates, outsourcing often provides better consistency across sites.
Whichever model a school chooses, the key is having a clear, written cleaning specification that sets out exactly what is expected — task by task, room by room, and frequency by frequency. This specification forms the basis for accountability and should be reviewed at least annually.
Infection Control: Lessons Worth Keeping
The heightened focus on hygiene prompted by the Covid-19 pandemic has left a lasting legacy in many schools. Some practices that were introduced as emergency measures have proven their worth and are now embedded in routine cleaning programmes.
Regular disinfection of high-touch surfaces throughout the day, not just during the main cleaning shift, is one such practice. Improved ventilation monitoring and maintenance is another. Enhanced hand hygiene infrastructure — including additional sanitiser stations at building entrances and in dining areas — has also become standard in many London schools. Schools with indoor air quality concerns may also benefit from our guidance on reducing workplace allergens, which applies equally to educational settings.
For schools in the South East, where pupil density can be particularly high in urban areas, maintaining robust infection control protocols remains a sensible investment in reducing absenteeism and keeping the school community healthy.
Practical Tips for Improving Your School's Cleaning Standards
Whether you are looking to overhaul your school's cleaning arrangements or simply tighten up existing practices, here are some actionable steps to consider.
- Audit your current provision: Walk the building at different times of day and note areas that are consistently below standard. Pay particular attention to washrooms, dining areas, and high-traffic corridors.
- Write a detailed specification: If you do not have a written cleaning specification, create one. List every room and space, the tasks required, and the frequency. This is essential whether you clean in-house or use a contractor.
- Review your COSHH arrangements: Ensure every product in use has a current risk assessment and SDS on file. Check that storage is secure and clearly signed. Confirm that all cleaning staff have received up-to-date training.
- Schedule deep cleans strategically: Map out the academic year and book deep cleaning during every holiday period. Do not leave it to the summer break alone — half terms provide valuable windows for targeted deep cleaning.
- Monitor and measure: Introduce a simple audit system — even a monthly walkround with a checklist — to track standards over time. This creates an evidence trail that can be valuable during Ofsted inspections.
- Engage the school community: Encourage staff and pupils to take shared responsibility for the environment. Simple measures like wiping down desks at the end of lessons and reporting maintenance issues promptly can make a significant difference.
