AHU cleaning in Ashford Common
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have plant that has been serviced but not cleaned and dirty coils holding back the airflow, we can help, from supply and extract fans, filter sections and internal panels onwards.
In a smaller place like Ashford Common, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Insurers, fire officers and environmental health officers all look at records. 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.

What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
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.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.

Fixed quotes for AHU cleaning in Ashford Common
The quote reflects the site in front of us. We take into account:
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
- The size of the system
- The condition of the system
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
Asking for a quote
You don’t need the technical terms. Just send:
- When the site is open and when it’s quiet
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
For a fixed quote, give us a ring on 0345 646 2711, or email photos 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 typically come back within one working day.
Managing agents and facilities teams in Ashford Common
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. A planned visit to Ashford Common fits your hours; an emergency does not.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or send details by email, and we will talk you through it.

Your questions about AHU cleaning in Ashford Common
Do you do school ventilation cleaning in Ashford Common in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Ashford Common, it pays to plan holiday dates ahead. You can call 0345 646 2711, or send details by email with the dates the site is empty.
Can the work in Ashford Common be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Ashford Common doesn’t have to lose a day’s trading. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Ashford Common is Ashford Hospital, about 1.7 miles north-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Ashford Common is about 16 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
If you run a surgery, dental practice or care home near Ashford Common, clean ventilation matters as much to you as to a hospital like Ashford Hospital (about 1.7 miles north-west).

When it’s something else

- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think before booking.
What the work covers

What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. A site near Ashford Common typically has room to park, so the questions are about access to the system and your hours.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
