AHU cleaning for kitchens and businesses in Little Chesterford
Where a building in Little Chesterford has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you have blocked condensate drains and slimy trays and odours coming through the supply air, we can help, from dampers and louvres, heating and cooling coils and internal panels onwards.
Work in a small place like Little Chesterford starts with agreeing access and timings.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Signs you need AHU cleaning in Little Chesterford
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
These are the problems we see most often:
- Dirty fans and fan housings
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
Workplaces around Great Chesterford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Questions to ask before you book
- Proof of accreditation you can verify
- If the quote is a fixed price or an estimate

- What’s included in the scope, part by part
Fixed quotes for AHU cleaning in Little Chesterford
The quote reflects the site in front of us. We consider:
- Parking and loading at the site
- The times the site is available
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.
What to send for a quote
When you call or email, it’s useful to have:
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.

The nearest hospital to Little Chesterford is Saffron Walden Community Hospital, about 2.9 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like Saffron Walden Community Hospital (about 2.9 miles south-east) to small clinics, depends on clean filters, coils and ducts.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Don’t store bins or materials near the intake
- Make sure condensate is draining away
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Questions from Little Chesterford
Do you work at weekends in Little Chesterford?
Yes, out-of-hours work is a big part of what we do. It means the site in Little Chesterford keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Will you come out to Little Chesterford?
Yes, Little Chesterford is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. With notice, the visit to Little Chesterford can be fitted around your bookings and events.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
Why us?
- Fixed quotes from a survey or photos
- Accredited under CHAS and SafeContractor, with ISO 9001
- We diagnose before we treat
- One number for every site across the South East and London
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Staff cleaning and specialist work aren’t 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. That part needs specialist access and equipment.
