UK-leading specialists in mission-critical cleaning – certified to ISO 14644-1:2022 Class 8 with all accessible surfaces guaranteed free from dust.
IT Cleaning Ltd are the UK’s leading specialists in Data Centre Cleaning, Data Hall Cleaning, Server Room Cleaning and Comms Room Cleaning — delivering services certified to ISO 14644-1:2022 Class 8 with all accessible surfaces guaranteed to be free from dust.
This level of cleaning and testing represents best practice for mission-critical environments, as recommended by the Data Centre Alliance (DCA). Original Equipment Manufacturers including NVIDIA and Cisco now specify ISO 14644-1 Class 8 as the operational environment for their equipment – with failure to meet the standard risking warranty invalidation on dust-related damage.
With over 23 years of experience cleaning and testing to ISO 14644 standards, IT Cleaning Ltd provide full certification and reporting following every clean.

HEPA-filtered methodology
HEPA vacuums and 0.3-micron air scrubbers capture dislodged particulate so it can't recontaminate hardware.
Live-environment cleaning
Cleaned around running kit with ESD-safe materials and non-residue solutions — zero downtime.
'Glove test' surface finish
All accessible surfaces guaranteed dust-free — the current UK best-practice specification.
Recent AWS findings show servers and switches can operate 4 years instead of 3 when contamination is controlled — delivering measurable savings and reduced downtime.
