AHU Cleaning in Audley End
AHU cleaning for Audley End, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Leaves and litter drawn into the unit
- Odours coming through the supply air
- Dirty coils holding back the airflow
AHU cleaning in Audley End, done properly
If the units serving a building in Audley End have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you are dealing with dirty filters cutting the airflow and fan sections that haven’t been cleaned in years, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Aftercare tips
To keep the system working properly between visits:
- Do not ignore odours coming through the grilles
- Change filters on schedule and log each change
- Check the drain tray is emptying during routine visits
- Don’t store bins or materials near the intake
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What affects the cost of AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- Travel, parking and unloading
- The condition we find in the survey
- The scale of the work
- The times the site is available
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Asking for a quote
What to send for a quote:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- A few general shots of the system
For a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
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. That part needs specialist access and equipment.
AHU cleaning in Audley End: local notes
Food Standards Agency data includes about 12 schools, colleges and universities and about 6 caring premises (care homes, nurseries and hospitals) within about 1.5 miles of central Audley End. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Saffron Walden Community Hospital is the nearest hospital, about 1.6 miles east of Audley End. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. At about 38 miles from central London, Audley End sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
For schools like Saffron Walden County High School, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near Audley End, clean ventilation matters as much to you as to a hospital like Saffron Walden Community Hospital (about 1.6 miles east).

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Audley End.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Why it’s worth doing now in Audley End
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. It’s simpler to plan the work at Audley End now than to arrange it in a hurry later.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.

Managing agents and facilities teams in Audley End
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
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.
Part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.

Do you clean school ventilation in Audley End in the holidays?
Yes, out-of-term visits are normal for schools. There are about 12 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Audley End. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you get to a site in Audley End?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How long does it take to clean an air handling unit?
Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. The shutdown is planned to fit, including evenings or weekends.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
