What affects the quote in Lower Green
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How big the system is
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Working hours and out-of-hours timing
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or drop us a line.
AHU cleaning for kitchens and businesses in Lower Green
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have plant that has been serviced but not cleaned and intake sections clogged with outdoor debris, we can put it right, from dampers and louvres, filter sections and internal panels onwards.
For a building in or near Lower Green, access is agreed in advance and the visit is planned around the journey.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Why act early in Lower Green
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. In a place like Lower Green, ductwork and fans are easy to forget until something goes wrong.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

When to call us in Lower Green
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Most sites get in touch after spotting one of these:
- Leaves and litter drawn into the unit
- Coils clogged with dust and debris
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
An inspection comes first for any ventilation job around Lower Green, so the cleaning matches what’s there.
Comparing quotes

For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.

What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Lower Green before we set off.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
FAQs for Lower Green
Is AHU cleaning available in Lower Green?
Yes. We work across London and the South East, and Lower Green is part of that. Get in touch with the details and we’ll arrange a survey.
Do you work at weekends in Lower Green?
Yes, we can come after you close and finish before you open. It means the site in Lower Green keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
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.
How much does AHU cleaning cost in Lower Green?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
