AHU cleaning in Woodford, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you’re dealing with units that have only ever had filter changes and dust-coated heating and cooling coils, we can put it right, from drain trays, supply and extract fans and filter sections onwards.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Woodford, as elsewhere, cleaning starts with an inspection of what’s there.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Woodford questions
Can you come to Woodford after we close?
Yes, nights and weekends are routine for us. It means the site in Woodford keeps running as normal. Let us know the hours you are closed and we will book within them.
Can parking be tricky for a job in Woodford?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Can you look after several 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 have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If pictures aren’t enough, we’ll survey first.
What else we do in Woodford
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Do you need AHU cleaning in Woodford?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
The symptoms we are asked about most include:
- Stale or musty smells from the ventilation
- Drain trays holding standing water
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
If you manage a school such as Woodbridge High School, ventilation cleaning is best booked for the holidays.
What your quote should include
- What insurance they carry
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What records you’ll receive afterwards
- Whether the work can be done while the site is closed

The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Before any visit in Woodford, we agree where the van can stop and how equipment reaches the system.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand

What affects the quote in Woodford
You will get a fixed price before any work starts. It’s based on:
- The condition of the system
- The number of sites or systems
- Site rules, permits and inductions
- Working hours and out-of-hours timing
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.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
For AHU cleaning in Woodford, phone us on 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote normally follows within one working day.
What the work involves, part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
