- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Condensate trays that won’t empty
How the visit 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. On site, the work takes one overnight shift for many single units, with bigger plant phased. Most London sites can’t stop for the day, so work in West Drayton is normally done overnight, early in the morning or at weekends.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures 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.
- After photos are taken and the certificate issued.
Preparing for the visit
- Clear the space around the work
- Let us know about parking and loading
- Agree a time when the area can be out of use

AHU cleaning in West Drayton, done properly
We clean air handling units for buildings in West Drayton and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with odours coming through the supply air and fan sections that haven’t been cleaned in years, across heating and cooling coils, supply and extract fans and drain trays.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in West Drayton is often done in the evening or at weekends. Loading and parking are planned with the building first.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, 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 West Drayton
Is parking a problem for work in West Drayton?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Do you do school ventilation cleaning in West Drayton in the summer holidays?
Yes, holiday work suits schools best. With about 23 schools and colleges on the FSA’s register within roughly a mile and a half of West Drayton, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711, or email photos with the dates the site is empty.
Do you work evenings or weekends?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Between visits
Aftercare is simple, and it helps at the next visit:
- Flag stale or damp smells in the supply air
- Don’t store bins or materials near the intake
- Watch for drips or damp patches near the plant
- Make sure condensate is draining away
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
What AHU cleaning cannot fix
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly before booking.
What we work on in West Drayton
- Filter sections

Why it’s worth doing now in West Drayton
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
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.

Fixed quotes for AHU cleaning in West Drayton
The price is fixed before any work begins. It takes into account:
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
- Parking and loading at the site
- What state the system is in
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

How the job changes from site to site
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
