AHU cleaning in Great Leighs
Our AHU cleans for sites in Great Leighs cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. We are often asked to deal with dirty fans and fan housings and filters that are clogged or overdue, on drain trays, dampers and louvres and filter sections.
Work in a small place like Great Leighs starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Common questions in Great Leighs
Can you work in Great Leighs outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Great Leighs can fit around your hours. Your opening times are the first thing we ask for.
Do you work in villages like Great Leighs?
Yes. Great Leighs is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What happens if you cannot reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
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.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Do you need AHU cleaning in Great Leighs?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Look out for any of the following:
- Plant that needs cleaning after a refit
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
Healthcare ventilation, from large hospitals like William Julien Courtauld Hospital (about 3.6 miles north-east) to small clinics, depends on clean filters, coils and ducts.

How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- What state the system is in
- Any permits to work or inductions
- The size of the system
- Parking and loading at the site
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What to send for a quote
To help us quote quickly, send us:
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.

Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Keep inspection doors on the unit in good order
- Don’t store bins or materials near the intake
- Plan the next inspection before the last report gets filed away
- 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.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
What happens on the day
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Great Leighs knowing what to expect.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Let us know about permits to work or site inductions
- Move anything stored near the system
- Tell us where we can park and unload
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
