AHU cleaning in Ashford: local notes
The FSA’s food hygiene register lists about 19 schools, colleges and universities and about 13 care, childcare and hospital premises with registered kitchens or food service within 1.5 miles or so of the middle of Ashford. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Ashford’s nearest hospital, Ashford Hospital, is about 0.7 miles north. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. We cover Ashford, about 17 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Workplaces around Ashford Surrey station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. School buildings such as Spelthorne College are usually done in the holidays, so classrooms aren’t disturbed. If you run a surgery, dental practice or care home near Ashford, clean ventilation matters as much to you as to a hospital like Ashford Hospital (about 0.7 miles north).

AHU cleaning in Ashford, done properly
If the units serving a building in Ashford have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Typical jobs include dust-coated heating and cooling coils and air handling units never cleaned inside, across internal panels, filter sections and dampers and louvres.
Buildings in towns like Ashford often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning, so you are not paying for more than the system needs.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Sites in a town like Ashford rarely need to lose trading hours, as the work fits around them.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in
How to get a quote
To get a fixed quote, ring 0345 646 2711, or send details by email 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 normally come back within one working day.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, 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.
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.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.

Why act early in Ashford
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. The sooner the work is done, the simpler the job for a site in Ashford.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Why book with us
- CHAS and SafeContractor accredited, with ISO 9001
- Out-of-hours work and a 24/7 emergency line
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Fixed quotes from a survey or photos

What affects the quote in Ashford
We quote each job individually. This is what makes a difference:
- Whether several sites go on one quote
- The size of the system
- What state the system is in
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- The paperwork from the last visit, if you have it
- The site address and the type of premises
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.
When it’s something else
Some problems need a different service or another trade:
- A system that is undersized for the building
- Damaged coils beyond cleaning
- The supply and extract ducts, quoted separately
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly before you book.
What the work covers
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Drain trays
- Internal panels
- Supply and extract fans
Aftercare tips
So the system stays in good health:
- Don’t store bins or materials near the intake
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Ashford questions
Do you clean school ventilation in Ashford in the holidays?
Yes. The holidays are the usual time for school work. With about 19 schools and colleges on the FSA’s register within roughly a mile and a half of Ashford, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Can the work in Ashford be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Is Ashford in your area?
Yes. Our technicians work in Ashford, within the South East and London area we cover.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
