AHU cleaning in Chevening: local notes
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 3 caring premises (care homes, nurseries and hospitals) serving food within about 1.5 miles of central Chevening. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Sevenoaks Hospital is the nearest hospital, about 2.8 miles east of Chevening. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. About 17 miles out from central London, Chevening is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
For schools like Combe Bank School, the holidays are the usual time to inspect and clean ventilation.

AHU cleaning in Chevening
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. Common call-outs are for air handling units with blocked filters and leaves and litter drawn into the unit, across heating and cooling coils, supply and extract fans and internal panels.
Work in a small place like Chevening starts with agreeing access and timings.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
The diagnosis comes before the price. We look at:
- Any permits to work or inductions
- How easy every part is to reach
- One-off work versus a regular cycle
- What state the system is in
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
What to send for a quote
Before you ask for a quote, gather:
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- A few general shots of the system
For a fixed quote, phone us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Chevening: your questions answered
Can the work in Chevening be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Chevening needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Can you clean school ventilation in Chevening during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chevening. Booking early in the term gives the best choice of holiday dates.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Is Chevening in your area?
Yes. Our technicians work in Chevening, within the South East and London area we cover.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
How long does it take to clean an air handling unit?
Cleaning takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, and you can ring 0345 646 2711, or send details by email to plan it.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- File each AHU report in the maintenance log
- Report musty smells from the vents straight away
- Don’t store bins or materials near the intake
- Change filters on schedule and log each change
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Honest limits
It’s worth knowing the limits before booking:
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think.
What the work covers
- Drain trays
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Internal panels
- Dampers and louvres
What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Rural roads and tight entrances are worth telling us about before a visit to Chevening.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
