How we handle AHU cleaning in Margaretting
Our AHU cleans for sites in Margaretting cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. We’re often asked to deal with blocked condensate drains and slimy trays and dust built up on fan impellers, across supply and extract fans, drain trays and dampers and louvres.
Work in a small place like Margaretting starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Questions from Margaretting
Is Margaretting in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Margaretting included. You can phone us on 0345 646 2711, or email photos and tell us what needs doing.
Can the work in Margaretting be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Margaretting can fit around your hours. Your opening times are the first thing we ask for.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.

What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.

As a guide, it takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, including evenings or weekends.
Honest limits
To be straight with you, some problems need a different fix:
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
- Coils that are corroded or leaking and need replacing
If you are not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer.
Where we work
- Internal panels
- Filter sections
- Dampers and louvres
- Drain trays
- Supply and extract fans
- Heating and cooling coils
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. A fault that closes a site in a village like Margaretting affects everyone who depends on it.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

How the visit works
Your staff don’t need to do much 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. Visits to a village like Margaretting are booked in advance, at a time that suits whoever runs the site.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one

Advice
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Margaretting and across Essex. Larger estates can be phased building by building to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- Whether we need access equipment or extra panels
- How big the system is
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The times we could work without disrupting the site
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels

Aftercare tips
How long the results last depends on use and care. We suggest:
- Don’t ignore odours coming through the grilles
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
