How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We fit London jobs around the building rather than the other way round, so a visit in Eastfields is typically out of hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system

How we handle AHU cleaning in Eastfields
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. The work covers drain trays, dampers and louvres and heating and cooling coils, and the jobs we see most are dirty coils holding back the airflow and plant that needs cleaning after a refit.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Eastfields.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

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 on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Why act early in Eastfields
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Choosing the date yourself beats having a fault choose it for you.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Why book with us
- Full insurance on every job
- CHAS, SafeContractor and ISO 9001
- Out-of-hours work and a 24/7 emergency line
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

Fixed quotes for AHU cleaning in Eastfields
Before we fix a price, we need to know a few things. We look at:
- How many systems or sites are involved
- Whether we need access equipment or extra panels
- The scale of the work
- The condition of the system
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
- Your last certificate, test record or report
To get a fixed quote, phone us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We typically come back within one working day.
Your questions about AHU cleaning in Eastfields
Can you clean school ventilation in Eastfields during the holidays?
Yes. The holidays are the usual time for school work. There are about 28 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Eastfields. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we will fit the work in.
How do you handle parking and loading in Eastfields?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will typically reply within one working day.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Can you clean without disrupting the building?
Yes, if daytime working isn’t practical. Tell us when the unit can go off and we will work to that.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.

What AHU cleaning looks like in Eastfields
There are about 28 schools, colleges and universities, about 57 caring premises (care homes, nurseries and hospitals) and about 3 hotels and B&Bs on the FSA’s food hygiene register within roughly a mile and a half of the centre of Eastfields. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. For Eastfields, the closest hospital is Wilson Hospital, roughly 0.9 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare ventilation, from large hospitals like Wilson Hospital (about 0.9 miles south-west) to small clinics, depends on clean filters, coils and ducts. If you manage offices or shops near Mitcham Eastfields station, their ventilation can be inspected and cleaned out of hours.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Keep filter changes on time and recorded
- Keep inspection doors on the unit in good order
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
What a clean won’t put right
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
- Problems with the unit’s controls or sensors
If in doubt, call us on 0345 646 2711 or email us and we will say what we think before booking.

Common problems we fix in Eastfields
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Eastfields, that is air they breathe for hours at a time.
What we’re most often called out for:
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
- Odours coming through the supply air
Classrooms and halls at schools such as St Mark's Church of England Academy are easiest to work in when pupils are away.
