What AHU cleaning looks like in Tongwell
The FSA’s food hygiene register lists about 14 schools, colleges and universities and about 16 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service in and around Tongwell, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 2.9 miles south of Tongwell is Milton Keynes University Hospital, the nearest hospital. 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 Tongwell, about 48 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included.
Healthcare buildings such as Milton Keynes University Hospital, about 2.9 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Tongwell, yours matters too.

How we handle AHU cleaning in Tongwell
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for coils clogged with dust and debris and blocked condensate drains and slimy trays, on drain trays, dampers and louvres and internal panels.
Somewhere as small as Tongwell, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Your questions about AHU cleaning in Tongwell
Do you cover smaller places like Tongwell?
Yes, we work in villages as well as towns, and Tongwell is covered. The journey is planned ahead, so a few details about the route help.
Do you do school ventilation cleaning in Tongwell in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 14 schools, colleges and universities with registered kitchens within about a mile and a half of Tongwell. Just ring 0345 646 2711 or email us with your term dates and we’ll plan around them.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
When to call us in Tongwell
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
The symptoms we are asked about most are:
- Stale or musty smells from the ventilation
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
For schools like Willen Primary School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- When the next visit should be, and why
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the work can be done while the site is closed
- What paperwork you get at the end
How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Tongwell, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
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. A few pictures and your last certificate or report help a lot. We normally come back within one working day.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Milton Keynes. Work can be phased by floor, building or site around the people who use them.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
When it’s something else
In fairness, some problems need a different fix:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.
What we work on in Tongwell
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Filter sections
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure the unit’s access doors open easily
- Book the next check in line with the report
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
