AHU cleaning for kitchens and businesses in Balmerlawn
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. If you have units needing a clean before a new tenant or handover and odours coming through the supply air, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Balmerlawn
Do you work in villages like Balmerlawn?
Yes. Villages and rural sites across the South East are part of our work, Balmerlawn included. The journey is planned ahead, so a few details about the route help.
Is AHU cleaning available in Balmerlawn?
Yes, Balmerlawn is within the area we cover across London and the South East. You can call 0345 646 2711, or email photos and tell us what needs doing.
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.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Can you clean the AHU out of hours?
Yes, wherever it helps the building. Tell us when the unit can go off and we will work to that.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
How long does an AHU clean take?
The work takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, and you can call 0345 646 2711 or send us an email to plan it.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: 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 is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Keeping the system healthy
After the visit, a few habits help the work last:
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What affects the quote in Balmerlawn
The survey tells us what the work involves. The main factors are:
- Access, including roofs, risers and ceiling voids
- Travel, parking and unloading
- What state the system is in
- How many systems or sites are involved
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
Asking for a quote
To speed up the quote, please include:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
What a clean won’t put right
In fairness, there are a few things this work will not fix:
- Coils that are corroded or leaking and need replacing
- Controls and BMS settings that run the unit
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly before you book.
Parts of the system we cover
- Dampers and louvres
- Drain trays
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Filter sections
What we do, step by step
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Balmerlawn can be planned properly.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet

How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
