About our AHU cleaning in Northfleet Green
Our AHU cleans for sites in Northfleet Green 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. If you have condensate trays that won’t empty and coils clogged with dust and debris, we can put it right.
Work in a small place like Northfleet Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Seeing the system in pictures first means the trip to Northfleet Green can be planned properly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
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 photos, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
What affects the cost of AHU cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- The scale of the work
- What state the system is in
The cost 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 we start, so there are no surprises.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- 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
- Any previous report or certificate
- Wide pictures of the system and the area around it
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711, or send details by email.
Your questions about AHU cleaning in Northfleet Green
Can the work in Northfleet Green be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Northfleet Green doesn’t have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Can you clean school ventilation in Northfleet Green during the holidays?
Yes, holiday work suits schools best. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Northfleet Green. You can phone us on 0345 646 2711 or drop us a line with the dates the site is empty.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Is a quote from photos possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

There are about 15 schools, colleges and universities and about 9 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within about 1.5 miles of central Northfleet Green. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 2.2 miles north-east of Northfleet Green is Gravesham Community Hospital, the nearest hospital.

Why deal with it now?
Stuffy rooms and stale smells in a building in Northfleet Green can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. In a small place like Northfleet Green, a system that fails can take a site out of use.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Honest limits
Some problems need a different service or another trade:
- A system that is undersized for the building
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
If in doubt, ring 0345 646 2711 or email us and we will say what we think.
What the work covers
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Internal panels
- Filter sections
- Dampers and louvres
Common problems we fix in Northfleet Green
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Look out for these warning signs:
- Plant that needs cleaning after a refit
- Coils clogged with dust and debris
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
Hospitals such as Gravesham Community Hospital (about 2.2 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Northfleet Green are no different.
