In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
AHU cleaning for kitchens and businesses in Coggins Mill
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. Common call-outs are for dirty fans and fan housings and air handling units never cleaned inside, across supply and extract fans, dampers and louvres and filter sections.
Somewhere as small as Coggins Mill, ducted ventilation is normally 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.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- The number of sites or systems
- What state the system is in
- The scale of the work
- Site requirements such as sign-in and permits
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Asking for a quote
We can often survey from pictures. Try to include:
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
Photos are enough for some jobs, while others need a look on site. 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.
Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
- Change filters on schedule and log each change
- Keep the certificate and photo report with the plant records
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Do you need AHU cleaning in Coggins Mill?
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Most sites get in touch when they notice one of these:
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
Healthcare ventilation, from large hospitals like Crowborough War Memorial Hospital (about 5.5 miles west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether a written report and photos are included
- Whether the price is fixed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether they recommend a next date
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Coggins Mill.
- We survey the unit from pictures 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.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
Your questions about AHU cleaning in Coggins Mill
Is Coggins Mill within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you offer AHU cleaning in Coggins Mill?
Yes, we work in Coggins Mill and the places around it. To start, call 0345 646 2711, or email photos with a few pictures of the system.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
What information do you need?
A short description and a few photos plus the address and your hours. If we need more, we’ll ask.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you survey before quoting?
Yes. We always survey first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
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 does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Somewhere as small as Coggins Mill, losing a kitchen or building to a fault is felt by everyone who uses it.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
