AHU cleaning in Aveley
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. The work covers internal panels, heating and cooling coils and drain trays, and people most often call us about odours coming through the supply air and coils clogged with dust and debris.
Around a place like Aveley, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Questions from Aveley
Can you come to Aveley after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Aveley needn’t be disturbed. Your opening times are the first thing we ask for.
Do you work in villages like Aveley?
Yes. Aveley is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where necessary. A fixed quote follows.
What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- The scale of the work
- Any permits to work or inductions
- Parking and loading at the site
- The condition of the system
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
Asking for a quote
To help us quote quickly, please include:
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Look at the condensate drain whenever the unit is serviced
- Stick to the filter change plan
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
The process
We’re used to working while the site is closed. 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 anything from half a day for one small unit to several shifts for a plant room full of them. Around Aveley, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- 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.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
What we’re called out for in Aveley
Whatever surrounds a building in Aveley, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Keep an eye out for any of the following:
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
If you manage a school such as Ormiston Park Academy, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- Whether a written report and photos are included
- When the next visit should be, and why
- What hours they’ll be on site
- Whether VAT is included
In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When something else is needed
A few issues sit outside what this work can do:
- The supply and extract ducts, quoted separately
- Breakdowns that need a mechanical engineer
- Building management system faults
