High Level Cleaning and Disinfection

High level cleaning is the essential and specialised task of cleaning and disinfecting out-of-reach areas in commercial and industrial environments, both internally and externally. From factory ceilings and warehouse racking to external cladding and rooftops, these elevated surfaces accumulate dust, debris, and hazardous contaminants that cannot be safely managed with standard cleaning methods. Our services are vital for maintaining hygiene, ensuring health and safety, and meeting stringent audit requirements in sectors ranging from food manufacturing and healthcare to industrial plants and retail spaces.

Due to the significant health and safety risks associated with working at height, this specialised work must only be performed by highly trained and certified professionals. At Rentokil Specialist Hygiene, our expert technicians are fully accredited, including PASMA and IPAF certifications, and are equipped to work in even the most challenging environments, such as ATEX zones and confined spaces. We conduct a thorough risk assessment for every project, ensuring all high level cleaning is completed safely, effectively, and with minimal disruption to your operations.

High level cleaning (sometimes called high reach cleaning) involves cleaning of both internal and external walls and surfaces that can't otherwise be cleaned from the ground

High level cleans are required in a range of commercial and industrial situations to keep the building and its contents clean and hygienic. This work usually involves manual or mechanical removal of contaminants using a range of techniques.

The health and safety implications and associated dangers with working from a height mean that high-level cleaning practices should always and only ever be undertaken by a trained professional with the correct equipment. Our expert technicians work to the highest industry health and safety standards and conduct an extensive risk assessment before commencing any high level cleans.

High level cleaning is needed wherever contaminants such as food dusts, dirt, debris, rodent droppings, algae, moss and mould gather in out of reach places

Generally the need for high level cleaning is for aesthetic, hygiene, or health and safety reasons. Businesses and industries that frequently require specialist high level industrial cleaning:

• Manufacturing Plants and Factories
• Warehouses and Distribution centres
• Food Production and Processing Centres
• Commercial Kitchen, Restaurants and Hospitality Sector
• Retail Spaces and Retail Environments
• Industrial Facilities including waste management and power plants
• Leisure Centres and Sports Facilities
• Healthcare and Infection Control Environments
• Commercial Units including Offices and Facilities Management

High level cleaning is usually needed on a regular, scheduled basis. The frequency depends on the type of clean and the importance of maintaining a clean environment. Removal of potential contaminants over a production line in a factory will likely need to be done more often than cleaning gutters on a warehouse roof, but everyone's needs are different.

Whether it's to comply with audit requirements, or to keep your building looking its best, we will discuss your requirements with you to ensure that you have the right cleaning schedule in place for you.

High level industrial cleaning is extremely important to your business. Neglecting high level cleaning can lead to significant health and safety risks from contamination, slip hazards and operational inefficiencies, as well as regulatory non-compliance.

Regular cleaning helps prevent damage and contamination of equipment and products, as well as promoting a positive image.

From internal high level cleaning to external and gutter cleaning, our team will create a tailored cleaning solution based on your needs and requirements. We have experience working in a range of environments such as factories, food manufacturing sites, retail units, leisure facilities and warehouses. Whether you require emergency high level cleaning or a more regular high level cleaning service to help you maintain a high standard of hygiene, our team of experts can support you to ensure that your building is safe and hygienic.

Once our hygiene consultant has surveyed your premises and assessed your high level cleaning requirements, we will provide service recommendations based on your business’ needs with a free no-obligation quote. Our specialist equipment allows our technicians to carry out high level cleaning on your premises and are capable of dealing with all high level cleaning situations, utilising high level access equipment and advanced techniques.

Our cleaning team is also trained in confined space cleaning and will deliver tailored cleaning solutions. We will safely carry out our professional high level cleaning solutions at a time convenient to you, to help minimise disruption to your business and production downtime.

Internal high level cleaning includes structure such as overhead girders, RSJs, ducting, light fittings and machinery, and can be a nightmare to reach using conventional methods. Deep layers of dust and debris quickly build up, and pose a threat of contamination to production lines or products below.

In the case of food factories, pests such as stored product insects can rapidly become established, causing an even bigger problem. In fact, regular high level cleaning forms part of BRC audit compliance as well as being a key feature in customer specific audits such as M&S Food manufacturing standard, Tesco Food Manufacturing Standards or the American Institute of Bakers . Regular and controlled high level cleaning is vital in protecting the production lines below and should form part of a HACCP assessment in every factory.

Moss, algae, industrial dirt and grime all cling to high level surfaces such as pitched roofs, windows, solar panels and facades. Over time these become unsightly, impacting on the first impression your building creates. A build up of fouling such as bird guano on exterior surfaces can also quickly cause issues with odour and bacteria, and even damage fixtures such as solar panels.

Cleaning hard to reach areas on the outside of your building is essential if you want to leave a lasting positive impression, as well as removing any health and safety risks associated with poor cleaning. Our teams use the correct access equipment to cause minimal disruption to your day whilst leaving no area uncleaned.

An immediate and expert response to unforeseen incidents like fire damage, flooding or biohazard contamination affecting elevated areas is essential in preventing further damage, particularly for manufacturing sites such as food factories. We deploy quickly and effectively, using our own, specialist cleaning equipment and solutions to contain and deal with any rapid response requirements you may have.

An Atex (or Ex) zone is an area where there is a heightened risk of explosion due to the nature of the products and environment present. Not only is it even more imperative that cleaning is carried out on a regular basis in these ATEX areas, but it's also vital that the correct training, equipment and procedures are used to keep everyone safe during a clean.

Industries commonly featuring ATEX environments include:

• Food Processing: Flour, sugar, starch, and grain dust.
• Pharmaceutical Manufacturing: Fine powders and chemical vapours.
• Woodworking: Wood dust.
• Industrial Chemical Plants: Flammable gases, vapours, and mists.
• Recycling & Waste Management: Various combustible dusts and gases.
• Metal Processing: Fine metal dusts (e.g., aluminium, magnesium).

We ensure safe and compliant high level cleaning in ATEX environments through a meticulous, risk-focused approach:

Expert and Certified Technicians: Our professionals are extensively trained in ATEX regulations and safe working practices, understanding dust behaviour and ignition prevention, and always wearing anti-static PPE. Our teams will put the safety of the site first to ensure we deliver outstanding results whilst keeping the site and your colleagues safe.

Rigorous Risk Assessment: We conduct thorough site-specific risk assessments, identifying ATEX zones and potential ignition sources to plan every step safely.

ATEX-Certified Equipment: We exclusively use intrinsically safe, ATEX-rated vacuum cleaners with anti-static components, explosion-proof motors, and advanced filtration. Our high level cleaning equipment also includes fully conductive poles and specialised access platforms suitable for ATEX zones, preventing static build-up and ignition.

Controlled Dust Removal: We focus on precise high level dust extraction using powerful ATEX-rated vacuums, carefully removing combustible dusts without dispersing them, thereby preventing airborne dust clouds that could lead to an explosion.
