What happens if it’s left?

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

AHU cleaning in St Mary in the Marsh, done properly
Our AHU cleaning covers sites in St Mary in the Marsh and the rest of Kent, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, drain trays and heating and cooling coils, and the jobs we see most are units that have only ever had filter changes and fan sections that haven’t been cleaned in years.
Somewhere as small as St Mary in the Marsh, ducted ventilation is normally 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.

Between visits
A little care between visits keeps the system in better shape. Our advice:
- Do not ignore odours coming through the grilles
- Keep the area around the fresh air intake clear
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
How we price AHU cleaning
Your quote is based on your site. We consider:
- How many systems or sites are involved
- How easy every part is to reach
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.
What we need to know
When you call or email, it’s useful to have:
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

What we are called out for in St Mary in the Marsh
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
These are the problems we see most often:
- Units needing a clean before a new tenant or handover
- Condensate trays that won’t empty
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
School buildings such as The Marsh Academy are usually done in the holidays, so classrooms are not disturbed.
Questions to ask before booking
- What’s included in the scope, part by part
- When they can work, and whether that is outside your opening hours
- How areas they can’t reach will be recorded
- Whether a survey comes first
St Mary in the Marsh questions
Do you work in villages like St Mary in the Marsh?
Yes. Villages and rural sites across the South East are part of our work, St Mary in the Marsh included. Just mention lanes, gates or anything else about the site when you book.
Do you cover St Mary in the Marsh for AHU cleaning?
Yes, St Mary in the Marsh is within the area we cover across London and the South East. Get in touch with the details and we’ll arrange a survey.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
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.
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 quote for both.
When it’s something else
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Controls and BMS settings that run the unit
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
If you are not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer.
Where we work
- Supply and extract fans
- Internal panels
- Drain trays

What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system help us make the most of a visit to a place like St Mary in the Marsh.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
