About our AHU cleaning in Birdbrook
No two plant rooms are the same, 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 before any cleaning starts. The work covers supply and extract fans, internal panels and heating and cooling coils, and common reasons people get in touch are drain trays holding standing water and dirty filters cutting the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Think of the report as the 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, ready for your insurer.

What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Leaking heating or cooling coils
- Faulty motors, drives or bearings
- Dirty ducts beyond the unit itself
If you’re not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer before you book.
Where we work
- Internal panels
- Drain trays
- Filter sections
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
Do you need AHU cleaning in Birdbrook?
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Keep an eye out for any of the following:
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
- Drain trays holding standing water
Around Birdbrook, an air handling unit’s drain tray is checked for standing water as a matter of course.
Questions to ask before booking
- How areas they can’t reach will be recorded
- Whether a survey comes first
- When they can work, and whether that is outside your opening hours
- Whether they’re fully insured
Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Planning a trip to Birdbrook ahead is easier for everyone than a rushed one.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. If you can send pictures, we can arrive in Birdbrook knowing what to expect.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Get a fixed quote
To get a fixed quote, ring 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Advice
What affects the quote in Birdbrook
Sites vary more than people expect. The main factors:
- How many systems or sites are involved
- Working hours and out-of-hours timing
- What state the system is in
- Parking and loading at the site
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- A few general shots of the system
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Your questions about AHU cleaning in Birdbrook
Can you get to a site in Birdbrook?
Yes, we work in villages as well as towns, and Birdbrook is covered. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Birdbrook?
Yes, we can come after you close and finish before you open. The work in Birdbrook can fit around your hours. Your opening times are the first thing we ask for.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you need to switch the unit off?
Yes, for the time we are working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
How the job changes from site to site
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
