Cleaning hours are estimated by combining your school's cleanable floor area with a productivity assumption for its building type, then adjusting for factors that make a site quicker or slower to clean. Beyond floor area, the estimate accounts for building layout, age, floor types, site access and the required cleaning standard. These factors are combined with a productivity rate to produce an indicative weekly cleaning-hours figure, without treating the calculation as a black box. ## What is a cleaning productivity rate? A productivity rate is expressed in square metres per labour hour (m²/hour) — it describes how much floor area one cleaner can reasonably clean to a given standard in an hour. A single productivity figure should not be applied to every school. Denser furniture, more washrooms, higher occupancy, older or more complex layouts, and enhanced cleaning standards all reduce the area a cleaner can cover per hour. This estimator applies a base productivity rate for your school type — an ICS operational assumption informed by industry cleaning-productivity practice, not a single external benchmark — then adjusts it using the complexity factors you provide. ## What affects cleaning hours? Eight recurring site characteristics typically explain most of the difference between two schools of similar size. Building layout Corridors, split levels and multiple blocks add time. Occupancy More pupils and staff using a space generally means more cleaning. Washroom provision Washrooms are labour-intensive relative to their floor area. Floor types Carpeted areas typically take longer than hard flooring. Cleaning frequency Daily, alternate-day or reduced schedules change total hours. Furniture density Densely furnished classrooms slow down cleaning tasks. High-traffic areas Entrances and circulation routes need more frequent attention. Service standards An enhanced specification requires more time than a standard one. ## How this estimate works The calculation follows a consistent, explainable flow — the same building information moves through each stage below before arriving at a weekly-hours figure and a staffing structure. Building area Your gross internal floor area (m²) Base productivity m²/hour rate for your school type Cleaning frequency Days per week the site is cleaned Complexity factors Layout, age, floor types, access, standard Weekly hours Your indicative weekly cleaning-hours figure Staffing structure Recommended, alternative and resilient options ## How should I use the result? Use the result as an indicative planning figure to sense-check your cleaning hours — not as a replacement for a measured, site-specific assessment. The result is suitable for: - Initial planning - Budget discussions - Staffing reviews - Comparing an existing cleaning allocation - Preparing for a specification review It is not: - A binding quotation - A guaranteed staffing requirement - A replacement for a site survey where detailed pricing is required ## About ICS Cleaning ICS Cleaning Services has delivered school and education cleaning across Yorkshire and Lincolnshire for over 30 years, with ISO 9001 and ISO 14001 accreditation and directly employed operational teams — the operational basis for the productivity assumptions used in this estimator.
