AHU cleaning for kitchens and businesses in Wrotham Heath
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers dampers and louvres, supply and extract fans and heating and cooling coils, and people most often call us about filters that are clogged or overdue and dust-coated heating and cooling coils.
Somewhere as small as Wrotham Heath, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Wrotham Heath, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down

Advice
How the job changes from site to site
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Managing agents and facilities teams in Wrotham Heath
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It takes into account:
- Site rules, permits and inductions
- How many systems or sites are involved
- The scale of the work
- Access, including roofs, risers and ceiling voids
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
What we need to know
To speed up the quote, send us:
- Any access panels or hatches you can see
- Problems your staff have spotted
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
Wrotham Heath questions
Can a school’s ventilation in Wrotham Heath be done out of term time?
Yes, out-of-term visits are normal for schools. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Wrotham Heath, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work overnight in Wrotham Heath?
Yes, nights and weekends are routine for us. That way a site in Wrotham Heath doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Is there a survey before the work?
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.
Can you price the work without visiting?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What happens if it’s left?
Stuffy rooms and stale smells in a building in Wrotham Heath can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. A fault that closes a site in a village like Wrotham Heath affects everyone who depends on it.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

What staff can safely do
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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Honest limits
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we’ll tell you honestly.
