About our AHU cleaning in Lambs Green
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for dust built up on fan impellers and rooms that smell stuffy when the system runs, across dampers and louvres, filter sections and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Lambs Green: your questions answered
Can you get to a site in Lambs Green?
Yes, we work in villages as well as towns, and Lambs Green is covered. The journey is planned ahead, so a few details about the route help.
Can you come to Lambs Green after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Lambs Green does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
How long does it take to clean an air handling unit?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and emergencies are covered by our 24/7 line.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply give us a ring on 0345 646 2711, or send details by email.
What affects the quote in Lambs Green
The diagnosis comes before the price. We look at:
- The times the site is available
- Where the site is and how we reach it
- The size of the system
- What state the system is in
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
What we need to know
To help us quote quickly, please include:
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- Detail shots of panels, filters and grilles
To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, call 0345 646 2711, or email photos.

What else we do in Lambs Green
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Different parts, different methods
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What AHU cleaning looks like in Lambs Green
About 27 miles out from central London, Lambs Green is part of the South East area we work across. Evening, overnight and weekend visits are all possible. About 2.7 miles east of Lambs Green is Crawley Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Classrooms and halls at schools such as Rusper Primary School are easiest to work in when pupils are away. If you run a surgery, dental practice or care home near Lambs Green, clean ventilation matters as much to you as to a hospital like Crawley Hospital (about 2.7 miles east).

Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Equipment tucked in a roof space or outbuilding near Lambs Green rarely gets looked at unless someone books it.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.
Why us?
- A fixed price before any work starts
- Full insurance on every job
- Every job surveyed first
- Photo reports with every job

Aftercare tips
Here’s the after-treatment advice, in brief:
- Keep filter changes on time and recorded
- Report musty smells from the vents right away
- Watch for drips or damp patches near the plant
- Plan the next inspection before the last report gets filed away
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
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.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. On site, it takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Lambs Green, lanes, gates and parking are worth mentioning in advance.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions
- Name a contact who can let us in at the agreed time
