Ventilation in Hitchin buildings
There are about 18 schools, colleges and universities, about 31 care, childcare and hospital premises and about 4 hotels and guest houses on the FSA’s food hygiene register within roughly a mile and a half of the centre of Hitchin. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Hitchin is about 32 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. Lister Hospital is the nearest hospital, about 3.1 miles south-east of Hitchin. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you manage offices or shops near Hitchin station, their ventilation can be inspected and cleaned out of hours. For schools like Hitchin Girls' School, the holidays are the usual time to inspect and clean ventilation. Healthcare buildings such as Lister Hospital, about 3.1 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Hitchin, yours matters too.

AHU cleaning in Hitchin
If the units serving a building in Hitchin have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers internal panels, drain trays and dampers and louvres, and common reasons people get in touch are filters that are clogged or overdue and stale or musty smells from the ventilation.
In Hitchin, ventilation in schools and offices is cleaned when the building is quiet: evenings, weekends or school holidays.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Aftercare tips
To keep the system working properly between visits:
- Look at the condensate drain whenever the unit is serviced
- Do not store bins or materials near the intake
- File each AHU report in the maintenance log
- Make sure the unit’s access doors open easily
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

How the job changes from site to site

Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
