Protecting buildings. Supporting compliance.
Ventilation hygiene is not just about cleanliness. It is about reducing risk, protecting occupants and being able to demonstrate that the duty has been discharged.
Deduct Ltd was established in 2015 and has spent the years since working inside buildings where the work has to happen around other people: live hospital wards, occupied offices, running production lines and vessels in drydock.
That shaped how we operate. Our engineers are directly employed rather than subcontracted, so the same standards apply on every site. Our reports follow one format regardless of sector, so an estates team can compare buildings and hand a coherent evidence set to an auditor, insurer or incoming provider.
We deliver ductwork and ventilation cleaning, kitchen and laundry extract cleaning, LEV cleaning, access panel installation and the compliance reporting that ties it all together — from our base in Bournville, across the whole of the UK.
Four commitments on every project
They sound simple. Most of the problems we are called in to fix come from one of them being skipped.
Assess before we clean
Condition is surveyed and measured first, so scope is based on the system rather than on an assumption about what it probably needs.
Declare what we could not reach
Inaccessible areas are listed, marked on the schematic and priced for access provision. We never certify what we have not seen.
Verify the result
The same test points are re-measured and re-photographed after works, so improvement is evidenced rather than claimed.
Leave the estate maintainable
Access panels, asset references and scheduled intervals mean the next cycle is straightforward instead of another investigation.
What we can mobilise
Access is usually what determines whether a system can genuinely be cleaned. We hold that capability in house.
