ICS Cleaning Services · 6 min read ## Introduction One of the most common questions schools ask when reviewing their cleaning services is how cleaning hours are actually calculated. Cleaning specifications often state a number of hours or staff positions, but the method used to determine those figures is not always clearly explained. In reality, cleaning hours are influenced by several factors including building size, layout, usage patterns and the tasks required to maintain hygiene standards. Understanding how these elements come together helps schools assess whether their current [cleaning provision](/services/school-cleaning) is appropriate for their environment. * * * ## Building Area and Cleaning Productivity A common starting point when estimating cleaning hours is the overall size of the building. Cleaning productivity is often expressed as the amount of floor area that can typically be cleaned within an hour. These productivity rates can vary depending on the type of space and the cleaning tasks involved. For example: - classrooms may have different productivity rates than corridors - washrooms require more detailed cleaning - sports halls and dining areas may require specialised attention Using these productivity assumptions allows cleaning providers to estimate how many hours are required to maintain the building. However, building size alone rarely tells the full story. * * * ## The Influence of Building Layout The layout of a school building can significantly influence cleaning productivity. Older school buildings often have: - multiple levels - narrow corridors - smaller classrooms - complex layouts These environments can make it more difficult to use larger cleaning equipment and may require more traditional cleaning methods. In contrast, newer school buildings often include: - wider corridors - open circulation areas - improved access for cleaning machinery These design features can improve productivity and allow cleaning teams to work more efficiently. As a result, two schools with similar floor areas may require different cleaning hours depending on their layout. * * * ## Task Frequencies and Hygiene Requirements Cleaning specifications usually include defined frequencies for different tasks. Some areas require daily attention, while others may be cleaned less frequently depending on their usage. Typical examples include: - daily classroom cleaning - washroom cleaning and sanitisation - corridor and circulation cleaning - periodic floor maintenance - window cleaning - deep cleaning during school holidays The frequency of these tasks contributes to the overall number of cleaning hours required. * * * ## Building Usage and School Operations Schools are active environments with varying patterns of usage throughout the day. Factors that can influence cleaning requirements include: - the number of students and staff - after-school activities - community use of facilities - dining hall usage - sports facilities Areas with higher footfall often require more frequent cleaning to maintain standards. Understanding how buildings are used allows cleaning providers to adjust service delivery accordingly. * * * ## Recruitment and Workforce Considerations Another important factor when determining cleaning hours is recruitment. In some locations, it may be more difficult to recruit for very small part-time roles. In these situations, it can sometimes be more practical to structure roles slightly differently to support recruitment and staff retention. For example, additional hours may be used to support daytime cleaning or janitorial tasks. Designing cleaning services that reflect both operational requirements and workforce realities helps ensure services remain stable over time. * * * ## Why Cleaning Hours Can Vary Between Schools Because of the factors above, it is common for schools of similar size to have slightly different cleaning hour allocations. Differences in building design, task frequencies, staffing structures and building usage can all influence how a cleaning service is organised. This is why cleaning services are typically reviewed periodically to ensure they remain appropriate for the school environment. * * * ## Understanding Your School's Cleaning Provision Schools reviewing their cleaning services may wish to understand how their current provision compares to typical industry assumptions. Our free [Cleaning Hours Estimator](/CleaningHoursEstimator) provides an indication of how cleaning hours are typically calculated based on building size and usage. While every school is unique, it can be a useful starting point for understanding whether current cleaning provision is broadly aligned with expected service levels. ### Build an Example Cleaning Schedule If you would like to see how a cleaning schedule might look for your school, use our School Cleaning Schedule Builder. This tool generates an indicative cleaning programme based on school type, building size and operational factors, helping school leaders and estates teams visualise how cleaning tasks may be structured across the week. [Open the School Cleaning Schedule Builder](/SchoolCleaningScheduleBuilder) If you are also reviewing labour levels or your current cleaning arrangement, you may also find these tools useful: [Cleaning Hours Estimator](/CleaningHoursEstimator)[School Cleaning Service Review](/ServiceReviewTool?sector=school) Cleaning Hours Insight Two schools with similar floor areas may require different cleaning hours depending on building layout, usage patterns and cleaning task frequencies. Why Layout Matters Older school buildings with narrow corridors and multiple staircases often require more manual cleaning work than modern buildings designed for machinery access. ### Useful tools School Cleaning Schedule Builder Generate an example cleaning schedule for your school.
