What affects the quote in Swattenden
A fixed price needs a few facts first. We check:
- The size of the system
- The condition of the system
- Site requirements such as sign-in and permits
- Travel, parking and unloading
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
What to send for a quote:
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
- Any previous report or certificate
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
About our AHU cleaning in Swattenden
Where a building in Swattenden has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers drain trays, internal panels and heating and cooling coils, and people most often call us about drain trays holding standing water and dust-coated heating and cooling coils.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Ventilation in Swattenden buildings
Going by the FSA’s register, there are about 4 schools, colleges and universities and about 3 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Swattenden. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Swattenden, the closest hospital is Benenden Hospital, roughly 3.9 miles east.

How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.

- Dampers and louvres
- Internal panels
- Supply and extract fans
- Drain trays
Common problems we fix in Swattenden
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
These are the problems we see most often:
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
- Dust-coated heating and cooling coils
- Drain trays holding standing water
Benenden Hospital, about 3.9 miles east, is the nearest hospital to Swattenden, and healthcare sites of every size need their supply air kept clean.

Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Somewhere as small as Swattenden, losing a kitchen or building to a fault is felt by everyone who uses it.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. If you can send photos, we can arrive in Swattenden knowing what to expect.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711, or email photos.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Swattenden: your questions answered
Is Swattenden within the area you cover?

Can you clean school ventilation in Swattenden during the holidays?
Yes, holiday work suits schools best. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Swattenden, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we’ll fit the work in.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then phone us on 0345 646 2711 or drop us a line.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
