School Deep Cleaning Guide for Summer 2025

Summer holidays are the perfect time for a school across the UK to carry out a thorough deep clean. With classrooms empty and corridors clear, cleaning teams can work without disrupting learning. This annual refresh helps schools meet hygiene standards, create a safe environment, and prepare for inspections in the new academic year.

In 2023/24, 18.1% of pupils in England were persistently absent, missing at least 10% of lessons. Many absences are linked to illness outbreaks, which can spread quickly when surfaces, washrooms, and shared areas aren’t cleaned to a high standard. A deep summer clean helps remove germs, allergens, and bacteria, reducing the risk of sickness when pupils return in September.

This guide outlines the ultimate summer deep cleaning checklist for schools, packed with practical steps, sector insights, and professional recommendations.

Why Summer Is the Best Time for School Deep Cleaning

When schools close for the summer, they present a rare window for uninterrupted maintenance. This is when cleaning companies can:

• Access all classrooms, halls, and offices without moving around pupils.
• Carry out floor restoration, painting, and repairs.
• Complete intensive sanitisation in kitchens, toilets, and changing areas.

Schools are also required to maintain hygiene standards under UK Health and Safety Executive (HSE) guidelines. Summer deep cleans help ensure compliance with these rules.

The Ultimate Summer Deep Cleaning Checklist

1. Classrooms and Corridors

Start with the learning spaces. Over the school year, dust, grime, and marks build up in classrooms. Summer is the time to tackle this in detail:

• Desks and chairs – Wash, sanitise, and remove chewing gum or graffiti.
• Walls and noticeboards – Wipe down to remove stains and allergens.
• Floors – Vacuum carpets, deep-clean hard floors, and apply polish if needed.
• Storage areas – Empty cupboards and shelves to clean inside and out.

For durable floor and surface cleaners, schools can use products such as the Heavy Duty Floor Cleaner and surface cleaners to keep surfaces spotless.

2. Toilets and Washrooms

Washrooms require special attention to meet both hygiene and odour control standards. During summer:

• Sanitise all toilets, sinks, and urinals thoroughly.
• Deep clean tiles, grout, and flooring to remove limescale and build-up.
• Restock supplies such as soap dispensers and paper towels.

Using antibacterial products like the Washroom Cleaner and Toilet Cleaner ensures bacteria are eliminated effectively.

3. School Canteens and Kitchens

School kitchens and canteens are high-risk hygiene zones. During the summer:

• Clean ovens, microwaves, and refrigeration units inside and out.
• Degrease extractor fans to maintain air quality.
• Sanitise all worktops, cutting boards, and storage areas.

Products like the Degreaser make removing built-up grease more efficient, ensuring compliance with Food Standards Agency guidelines.

4. School Sports Halls and Gym Areas

Sports facilities see heavy use, which means deep cleaning is vital to keep them safe:

• Sweep and scrub floors, then apply a protective finish where needed.
• Clean and disinfect gym equipment to remove bacteria from shared surfaces.
• Wipe down walls, mirrors, and high-level dust areas.

Using a multipurpose disinfectant like the Surface Sanitiser ensures equipment is ready for September.

5. Staffrooms and Offices

These spaces are often overlooked but are crucial for staff wellbeing:

• Clean desks, IT equipment, and phones.
• Wipe fridges, microwaves, and kitchenettes.
• Vacuum carpets and deep-clean upholstery.

The Upholstery Cleaner is ideal for keeping staffroom seating hygienic and fresh.

6. High-Traffic Areas

Reception areas, hallways, and staircases are the first impression for visitors and inspectors:

• Clean entrance mats and flooring to remove dirt and debris.
• Polish glass doors and windows for a professional look.
• Dust and disinfect handrails and door handles.

Disinfectants will remove bacteria and ensure a healthy school environment.

Health, Safety and Compliance for School Cleaning

A summer deep clean is more than appearance; it’s about meeting health and safety standards. The Health and Safety Executive (HSE) states that all educational environments must maintain a safe and hygienic condition to prevent slips, trips, infections, and contamination.

Why Professional Cleaning Services Matter

While in-house teams can handle daily cleaning, professional contractors bring:

• Specialist equipment for deep carpet cleaning, floor stripping, and air quality maintenance.
• Industry-grade disinfectants safe for children and compliant with COSHH standards.
• Expert knowledge of educational facility requirements.

A summer deep clean is essential for every UK school. It safeguards pupil health, prepares for inspections, and ensures facilities look their best for the new academic year.
