How we handle AHU cleaning in Lisson Grove
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers internal panels, heating and cooling coils and filter sections, and common reasons people get in touch are rooms that smell stuffy when the system runs and leaves and litter drawn into the unit.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Lisson Grove is normally planned out of hours. Parking and loading are agreed with the building in advance.
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.

Aftercare tips
Once we have finished, these simple steps help:
- File each AHU report in the maintenance log
- Change filters on schedule and log each change
- Report stiff or damaged access doors
- Check the drain tray is emptying during routine visits
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Expect the work in Lisson Grove to happen after your last customer leaves, not during trading.
- The survey covers the unit, its access and how it can be shut down.

Advice
Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Faulty motors, drives or bearings
- Ductwork downstream of the unit, which is a separate clean
- A system that’s undersized for the building
Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover

Questions from Lisson Grove
Can you clean school ventilation in Lisson Grove during the holidays?
Yes, out-of-term visits are normal for schools. Around Lisson Grove, the Food Standards Agency lists about 71 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Can the work in Lisson Grove be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Lisson Grove keeps running as normal. Let us know the hours you are closed and we’ll book within them.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How the job changes from site to site
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.

Leave it or put it right?

For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Access, including roofs, risers and ceiling voids
- The scale of the work
- One-off work versus a regular cycle
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or use the quote form for straight advice and a fixed quote.
What we need to know
Before you ask for a quote, gather:
- The paperwork from the last visit, if you have it
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
