Data Centre and Server Room Deep Cleaning Services

Cleaning Data Centres, Comms rooms and Server Rooms is a specialised job. Data centres are intricate and complex environments, containing sensitive components and requiring a thorough, meticulous and expert approach. If left unmaintained, dust and lint can accumulate and cause damage to expensive equipment as well as affect performance of hardware.

At Rentokil Specialist Hygiene we recognise the importance of ensuring data centres and server rooms are regularly cleaned and maintained, and provide specialist cleaning services across the UK to keep your IT infrastructure working to its optimal level. Post clean testing is also provided to validate cleaning is carried out in accordance with ISO 14644 industry standards.

What is Data Centre Cleaning?

Whether a small IT server room, or a cavernous data centre stretching hundreds of metres and supporting thousands of data processors, the need for cleaning remains the same.

Data centres, including comms rooms and server rooms, are any buildings or rooms where IT hardware such as servers, storage devices and networking equipment, and they act as the engine room for cloud storage across the country. As the IT revolution has gathered pace over the last few years, along with increasing energy costs, the need to maintain these rooms has come to the forefront of business maintenance planning.

Due to the sheer amount of equipment within, they present complex cleaning environments but must be cleaned and maintained regularly to ensure they operate effectively.

When is Data Centre Cleaning required?

Due to the sheer amount of equipment within, they present complex cleaning environments but must be cleaned and maintained regularly to ensure they operate effectively.

If left unchecked, dust and lint build up on ledges, surfaces and within areas such as sub floor voids. This particulate build up can easily get inside computer equipment where it settles in delicate circuitry and can cause short circuits and small amounts of damage that can have disastrous consequences. For many customers, data is money, and a data loss or outage can be very expensive indeed. In extreme cases, electrical fires can occur, causing huge amounts of damage both in hardware and data loss.

A well maintained data centre is also an energy efficient one. Data centres are one of the primary users of UK energy countrywide and as such, energy efficiency is extremely important. By regularly maintaining and cleaning within data centres, hardware performs in an efficient manner and costs are kept to a minimum.

Professional and Compliant Data Centre Cleaning Service

Cleaning a data centre is a clinical process that requires a balance of technical expertise and specialised experience. Because standard janitorial methods can introduce static or airborne pollutants, Rentokil Specialist Hygiene follows a rigorous, multi-stage protocol designed to protect your uptime and hardware integrity.

  • 1. Pre-Clean Assessment & Risk Mitigation - Before a single floor tile is lifted, our expert technicians conduct a comprehensive site risk assessment. This identifies high-sensitivity zones and determines the optimal approach to cleaning around live equipment without disruption.

  • 2. Specialist PPE & Static Control - To protect delicate circuit boards from Electrostatic Discharge (ESD), our teams arrive in approved, anti-static PPE. This prevents the technicians themselves from becoming a source of static buildup while moving through the "white space".

  • 3. Advanced Technical Cleaning Methodology - We utilise a specialised toolkit specifically engineered for controlled environments:

    • HEPA-Filtered Vacuums: These capture micro-particles as small as 0.3 microns, ensuring dust is extracted from the environment rather than recirculated into server fans.
    • Microfibre & ESD Chemistry: We use lint-free microfibre products and specialist electrostatic sprays that neutralise surface charges.
    • Sub-Floor & Plenum Decontamination: We clean the void beneath raised floor tiles to remove "zinc whiskers" and accumulated debris that can be pushed into servers by the cooling system.
    • High-Level Infrastructure: We decontaminate cable trays and cabinet tops to prevent "dust-fall" onto active components.

  • 4. Compliant Testing & Validation - A clean isn’t finished until it is proven. We provide a post-clean sampling and analysis report conducted to  ISO 14644 standards. This technical validation confirms that your facility meets the industry-recognised norms for particulate counts, providing you with an audit trail for compliance and insurance purposes.

    With over 50 years specialist cleaning experience, we provide:

    • Trained and experienced specialist technicians across the UK
    • Professional and modern cleaning equipment and techniques
    • Industry PPE
    • Flexible working to ensure hard to reach areas such as sub floor voids and overhead cable runs are cleaned effectively.
    • An ISO 14644 accredited post-cleaning testing service to provide an audit trail and proof of service in line with industry standards.

Where is Data Centre and Server Room Cleaning Suitable For?

With the ever growing rise in information technology, the need for data centres to house large amounts of infrastructure has never been higher. Server room cleaning is vital for many customers, but in particular:

Higher Education Facilities

Schools and universities have multiple IT suites, with server rooms and IT rooms present in most buildings.

Retail Banks

The surge in online banking requires secure networking and data storage. Banks need server room cleans to protect their networks.

Call Centres

Telecommunications operations often have large suites of IT equipment, and a clear need to ensure it is cleaned professionally and regularly.

Government Departments

Modern government buildings rely heavily on online systems to help UK citizens. Server rooms here are high priority and must be cleaned regularly and carefully.

Hospitals and Medical Practices

Hospitals - often involving large data rooms. Hospitals rely on the online world to operate effectively in fast moving environments.

Pharmaceutical Research Laboratories

Often with multiple data rooms. Hygiene and cleanliness is top of the agenda in these sensitive environments.

Frequently Asked Questions on Data Server Cleaning


  • How are data centres cleaned?

    Carefully and professionally - using methods and materials that won't create electrostatic or cause harm to sensitive components.

    Experience and knowledge of the environments being cleaned are essential skills for data centre cleaning experts. Colleagues trained in testing standards are also a pre-requisite.


  • How Often Should a Data Centre Be Cleaned?

    To maintain hardware longevity and prevent downtime caused by particulate contamination, Rentokil Specialist Hygiene recommends a tiered frequency strategy aligned with ISO 14644.

    • Daily: High-Traffic Management Focus on "grey space" and entry points. Corridors, staging areas, and personnel airlocks should be cleaned daily to prevent dust and debris from being tracked into the sensitive white space.
    • Weekly: Tactical Maintenance Moderate to light traffic zones, including peripheral walkways and packing areas, require a thorough cleaning once or twice a week to maintain a baseline of environmental hygiene.
    • Monthly: Comprehensive Sanitation A full-facility sweep should be conducted monthly. This involves a more detailed cleaning of surfaces that don't see daily contact but still accumulate static-attracted dust.
    • Quarterly: Technical Deep Cleaning Engage experts, such as Rentokil Specialist Hygiene every quarter to carry out a deep cleaning including high-level cleaning of cable trays and technical infrastructure, as well as the critical cleaning of sub-floor voids (plenums) to ensure airflow remains uncontaminated.

  • How much does data centre cleansing cost?

    This varies enormously depending on the size of the room, from small cupboards, to vast warehouses. We will provide a free, no obligation quote based on your specific needs.


  • What is the biggest problem for data centres?

    Damage from surface and airborne particles to circuits can be catastrophic in terms of lost data and function. Data is money.


  • What is the data centre cleaning ISO standard?

    Cleanliness in data centres is based on the international ISO 14644 standard which dictates the levels of particulate acceptable in the room.

    ISO 14644 is an international standard for cleanrooms (which Data Centres and Server rooms are classified as). It defines requirements for monitoring and cleaning to ensure that they are properly maintained.

    Typically, data centres are classed as Class 8 environments, with set limits for the amount of airborne particles that can be present. Post clean testing to ISO 14644 standards ensures that data centres are cleaned to a set standard before being handed over.

    All data centre cleans from Rentokil Specialist Hygiene  are provided with post clean sampling to ensure the room or building is compliant.
