AHU cleaning for kitchens and businesses in Holloway
Our AHU cleaning covers sites in Holloway and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you’re dealing with dirty coils holding back the airflow and odours coming through the supply air, we can help, from dampers and louvres, filter sections and heating and cooling coils onwards.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Holloway, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

What happens on the day
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. For a job in Holloway, tell us about loading bays, permits, lifts and roof access when you book.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Have your last certificate or report to hand
- Clear the space around the work
- Let us know about permits to work or site inductions

Advice
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Plan the next inspection before the last report gets filed away
- Store the TR19 paperwork where auditors can find it
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What we’re called out for in Holloway
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
The symptoms we’re asked about most include:
- Air handling units with blocked filters
- Air handling units never cleaned inside
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
Healthcare buildings such as Royal Northern Hospital, about under half a mile north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Holloway, yours matters too.
Before booking anyone
- Whether the work can be done while the site is closed
- Whether they recommend a next date
- Whether the figure could change on the day
- Proof of insurance
What affects the cost of AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- Whether it’s a one-off visit or part of a schedule
- How big the system is
- The number of sites or systems
- The times the site is available
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
Asking for a quote
When you contact us, these details help:
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The roof, plant room or outside wall the system runs to
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.
