About our AHU cleaning in Rowsham
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers supply and extract fans, heating and cooling coils and internal panels, and the jobs we see most are units that have only ever had filter changes and dirty fans and fan housings.
Work in a small place like Rowsham starts with agreeing access and timings.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

The process
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Rowsham are booked in advance, at a time that suits whoever runs the site.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need

Advice
What affects the cost of AHU cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- The scale of the work
- Travel, parking and unloading
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.
What we need to know
There’s no need for technical detail. Just send:
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
- A few general shots of the system
- The site address and the type of premises
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Rowsham questions
Do you clean school ventilation in Rowsham in the holidays?
Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Rowsham, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Can you work in Rowsham outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Rowsham needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
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 on one programme. Each site gets its own report and photos.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Why it’s worth doing now in Rowsham
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Rural sites cannot always move to another kitchen or room when something fails.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Report musty smells from the vents straight away
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Look at the condensate drain whenever the unit is serviced
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Common problems we fix in Rowsham
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Clients typically contact us when they notice something like this:
- Air handling units with blocked filters
- Odours coming through the supply air
- Plant that has been serviced but not cleaned
- Air handling units due a clean after building work
Wherever a school like Wingrave Church of England Combined School has ducted ventilation, a half-term visit keeps the work out of lesson time.
