AHU cleaning for kitchens and businesses in Dengie
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. Common call-outs are for debris and leaves in the fresh air intake and air handling units with blocked filters, on dampers and louvres, drain trays and supply and extract fans.
Somewhere as small as Dengie, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What happens on the day
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 first, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Dengie.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
Ask for a quote
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, then send a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- Parking and loading at the site
- The scale of the work
- A single visit or a regular plan
- Whether several sites go on one quote
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
We can often survey from photos. The most useful are:
- When the site is open and when it’s quiet
- A few general shots of the system
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Then phone us on 0345 646 2711 or email us.
Signs you need AHU cleaning in Dengie
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Look out for any of the following:
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
Around Dengie, an air handling unit’s drain tray is checked for standing water as a matter of course.

Your questions about AHU cleaning in Dengie
Do you work in villages like Dengie?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Is Dengie in your area for AHU cleaning?
Yes, Dengie is within the area we cover across London and the South East. To start, give us a ring on 0345 646 2711, or send details by email with a few photos of the system.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
What happens if you can’t reach some of it?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Do you survey before quoting?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Dengie simpler. It’s simpler to plan the work at Dengie now than to arrange it in a hurry later.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
