AHU cleaning for kitchens and businesses in Berden
Where a building in Berden has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you have coils clogged with dust and debris and rooms that smell stuffy when the system runs, we can put it right, from heating and cooling coils, supply and extract fans and internal panels onwards.
For a building in or near Berden, access is agreed in advance and the visit is planned around the journey.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.

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 the area around the work is covered and protected. The work itself takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Berden.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
Ask for a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Common questions in Berden
Can a school’s ventilation in Berden be done out of term time?
Yes, and it’s the easiest time to do it. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Berden. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
Do you cover smaller places like Berden?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you look after several sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Can you clean the AHU out of hours?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
Can you quote from photos?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Our emergency line runs 24/7, but a planned visit to Berden is calmer for everyone.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

How we price AHU cleaning
Your quote is based on your site. We take into account:
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
- The condition we find in the survey
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, call us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- The postcode and the type of business
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
When to call us in Berden
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
If you notice any of these, it’s worth a diagnosis:
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
- Units that have only ever had filter changes
- Dust built up on fan impellers
Herts and Essex Hospital, about 5.8 miles south, is the nearest hospital to Berden, and healthcare sites of every size need their supply air kept clean.
