- Debris and leaves in the fresh air intake
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
What a clean will not put right
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Building management system faults
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before you book.
Where we work
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans

- Drain trays
- Filter sections
How we handle AHU cleaning in Henham
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, dampers and louvres and internal panels, and common reasons people get in touch are drain trays holding standing water and dirty coils holding back the airflow.
In a village or hamlet like Henham, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Planning a trip to Henham ahead is easier for everyone than a rushed one.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Fixed quotes for AHU cleaning in Henham
Some jobs are bigger than they look, and some smaller. What affects the quote:
- What state the system is in
- How big the system is
- How easy every part is to reach
- One-off work versus a regular cycle
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
What to send for a quote
What to send for a quote:
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, ring 0345 646 2711 or drop us a line.
Henham: your questions answered
Is Henham within the area you cover?
Yes. Henham is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you work in Henham outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Henham can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
How the visit works
Every visit runs to the same pattern: protect the area, make the system safe, do the work, clear away and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Henham.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time
How to get a quote
To get a fixed quote, ring 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll typically have a quote within one working day.

What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
