Data Centre Cleaning Specialists
Specialist Data Hall, Server Room and Comms Room Cleaning throughout the UK.
UK-leading Data Centre Cleaning specialists for mission-critical environments – cleaning and testing to ISO 14644-1 Class 8, with all accessible surfaces cleaned free from dust.
IT Cleaning Ltd has specialised in professional Data Centre Cleaning and mission-critical IT environments since 2002, providing specialist services throughout the UK. Our cleaning procedures are designed to control particulate contamination on accessible surfaces and within the operational environment, with cleaning and testing available to ISO 14644-1 Class 8.
This level of contamination control represents recognised best practice for mission-critical environments. The Data Centre Alliance (DCA) recommends appropriate contamination control, while equipment manufacturers including NVIDIA specify environmental cleanliness requirements for certain data centre and computing equipment.
With over 24 years of specialist experience, IT Cleaning Ltd provides cleaning, particle testing, certification and detailed reporting, giving clients documented evidence of the environmental condition following the clean.
How we clean Data Centres
ISO 14644-1 Class 8
Cleaning and testing using a Solair 5100+ particle counter, with a Certificate of Conformity and detailed post-clean report. Annual testing recommended.
HEPA-filtered methodology
HEPA-filtered vacuums and 0.3-micron air scrubbers capture disturbed particulate, helping prevent contaminants from being redistributed within the data hall.
Live-environment cleaning
Cleaned around operational IT equipment with ESD-safe materials and non-residue solutions — zero downtime.
'Glove test' surface finish
All accessible surfaces cleaned free from visible dust in accordance with our technical cleaning specification.
Why Data Centre Cleaning Matters
Particulate contamination can accumulate on IT equipment, cooling components and within critical airflow paths. If left uncontrolled, contamination can restrict airflow, reduce cooling efficiency and increase the risk of equipment-related issues.
- Restricted airflow and increased cooling demand.
- Contamination of fans, filters and heatsinks.
- Fan wear, bearing damage and blocked heatsinks.
- Increased risk of equipment overheating.
- Electrostatic and conductive contamination risks.
- Increased cooling energy demand across the data hall.
- Contamination entering servers, switches and other critical IT equipment.
ISO 14644 Cleaning, Testing & Certification
01 · Survey
Baseline particulate reading with a Solair 5100+ so you see the level and size of particulates before we start.
02 · Clean
HEPA vacuums, tacky-wipe systems and microfibre — from underfloor voids to high-level surfaces and equipment exteriors.
03 · Test & Report
Post-clean airborne particle testing to verify compliance with ISO 14644-3 Class 8, followed by a detailed report and Certificate of Conformity.
Specialist Comms Room Cleaning
Comms Room Cleaning requires the same controlled approach as larger Data Centre and Server Room environments. Communications rooms can contain network switches, routers, patch panels, UPS equipment, server hardware and other critical infrastructure that may be vulnerable to particulate contamination.
IT Cleaning Ltd provides specialist Comms Room Cleaning throughout the UK, including the cleaning of floors, accessible equipment surfaces, cabinet exteriors, high-level surfaces and floor voids where required. HEPA-filtered vacuuming and controlled wiping techniques are used to remove accumulated particulate without introducing unnecessary contamination into the environment.
Where environmental cleanliness needs to be demonstrated, airborne particle testing can also be undertaken to determine whether the environment meets ISO 14644-1 Class 8 particle concentration limits, providing documented evidence of the condition of the room following cleaning.
How Often Should a Comms Room Be Cleaned?
The appropriate cleaning frequency depends on equipment density, personnel activity, filtration, construction activity and measured particulate levels. For many operational comms rooms, annual professional cleaning provides a sensible starting point, with more frequent cleaning considered where contamination levels or environmental conditions indicate a greater risk.
Data Centre Cleaning FAQs
How often should a data centre be professionally cleaned?
Regular cleaning frequency depends on the environment, equipment density, airflow, personnel activity and contamination risk. As a general approach, data centres should be inspected regularly and cleaned when particulate or surface contamination indicates it is required. Annual cleaning and ISO 14644 particle testing can provide a useful benchmark for contamination control.
Can you clean a live data centre without shutting down equipment?
Yes. IT Cleaning Ltd specialises in cleaning live mission-critical environments. We use HEPA-filtered equipment, ESD-safe materials and controlled cleaning methods designed for use around operational servers, switches, storage and other critical IT equipment.
What does ISO 14644-1 Class 8 mean for a data centre?
ISO 14644-1 defines air cleanliness classifications based on airborne particle concentrations. Testing a data centre to ISO 14644-1 Class 8 provides measurable evidence of airborne particulate cleanliness rather than relying solely on visual inspection.
Do you clean underneath raised access floors?
Yes. Raised-floor voids and cold-air plenums can accumulate significant particulate contamination. Where included within the agreed scope, we clean accessible underfloor areas using specialist HEPA-filtered vacuum equipment and controlled cleaning methods.
Do you clean servers and IT equipment internally?
Yes. Internal IT equipment cleaning is available as a specialist service for servers, switches, storage equipment and other critical hardware. This requires different procedures from general data hall surface cleaning and is carried out using methods appropriate for sensitive electronic equipment.
Do you provide ISO 14644 particle testing and certification after cleaning?
Yes. Post-clean airborne particle testing can be carried out to determine compliance with ISO 14644-3 Class 8. Following testing, IT Cleaning Ltd provides documented results, reporting and a Certificate of Conformity.
