AHU cleaning for kitchens and businesses in Steward's Green
We clean air handling units for buildings in Steward's Green and across Essex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have units that have only ever had filter changes and dust built up on fan impellers, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with pictures of the work, 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.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
What AHU cleaning can’t fix
To be straight with you, some problems need a different fix:
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
- Leaking heating or cooling coils
If you’re not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer.
What the work covers
- Drain trays
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils

What affects the quote in Steward's Green
Before we fix a price, we need to know a few things. We look at:
- Working hours and out-of-hours timing
- Parking and loading at the site
- One-off work versus a regular cycle
- Site rules, permits and inductions
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 play a part.
Asking for a quote
Before you ask for a quote, gather:
- A few general shots of the system
- The times we could work without disrupting the site
- The postcode and the type of business
- Problems your staff have spotted
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
Questions from Steward's Green
Do you clean school ventilation in Steward's Green in the holidays?
Yes, out-of-term visits are normal for schools. Around Steward's Green, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Do you cover smaller places like Steward's Green?
Yes. Steward's Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you quote from photos?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
How long does an AHU clean take?
It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Steward's Green.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend
