AHU cleaning for kitchens and businesses in Kinsbourne Green
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, filter sections and supply and extract fans, and common reasons people get in touch are air handling units never cleaned inside and blocked condensate drains and slimy trays.
Somewhere as small as Kinsbourne Green, ducted ventilation is usually 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’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Kinsbourne Green questions
Can the work in Kinsbourne Green be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Kinsbourne Green can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you offer AHU cleaning in Kinsbourne Green?
Yes, we work in Kinsbourne Green and the places around it. To start, ring 0345 646 2711 or email us with a few photos of the system.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

There are about 3 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within 1.5 miles or so of the middle of Kinsbourne Green. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.

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’ll take a look and give you a fixed quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Any permits to work or inductions
- How easy every part is to reach
- Working hours and out-of-hours timing
- Where the site is and how we reach it
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
Helping us quote
To speed up the quote, send us:
- Any previous report or certificate
- When the site is open and when it’s quiet
- A few general shots of the system
- Problems your staff have spotted
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, call 0345 646 2711, or send details by email.
The process
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Kinsbourne Green.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
To get a fixed quote, call 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
Related advice
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. A fault that closes a site in a village like Kinsbourne Green affects everyone who depends on it.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Honest limits
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
If in doubt, ring 0345 646 2711, or send details by email and we’ll say what we think.
