AHU cleaning in St Michaels
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote before any cleaning starts. Common call-outs are for units needing a clean before a new tenant or handover and drain trays holding standing water, on supply and extract fans, heating and cooling coils and drain trays.
Work in a small place like St Michaels starts with agreeing access and timings.
The sign-off is always in writing: a dated report with photos of the work, 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.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Stick to the filter change plan
- Book the next check in line with the report
- Make sure the unit’s access doors open easily
- File each AHU report in the maintenance log
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
- Site rules, permits and inductions
- The scale of the work
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before work begins.
Helping us quote
To speed up the quote, send us:
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.
How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, 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 St Michaels.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
Ask for a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.
Advice
Leave it or put it right?
If people in a building in St Michaels complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. It’s worth booking a check, because nobody sees inside a duct day to day.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

When something else is needed
A few issues sit outside what this work can do:
- Controls and BMS settings that run the unit
- A system that is undersized for the building
- Coils that are corroded or leaking and need replacing
If in doubt, phone us on 0345 646 2711 or email us and we will say what we think before booking.
What the work covers
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Filter sections
- Drain trays
- Supply and extract fans
Different parts, different methods
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
St Michaels: your questions answered
Can you come to St Michaels after we close?
Yes, nights and weekends are routine for us. The work in St Michaels can fit around your hours. Let us know the hours you’re closed and we will book within them.
Is St Michaels in your area for AHU cleaning?
Yes. We work across London and the South East, and St Michaels is part of that. To start, give us a ring on 0345 646 2711 or use the quote form with a few photos of the system.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Can you price the work without visiting?
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.
How far ahead should we book?
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 give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
What’s TR19?
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 expects a risk-based approach.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
