AHU cleaning in Sullington
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Common call-outs are for odours coming through the supply air and plant that has been serviced but not cleaned, across internal panels, dampers and louvres and supply and extract fans.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Sullington questions
Can the work in Sullington be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can ventilation in schools around Sullington be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Sullington, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
How long will the unit be out of action?
Expect it to take one overnight shift for many single units, with bigger plant phased. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711, or email photos with the site type, opening hours and a few photos.
How do you protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
What we do, step by step
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes one overnight shift for many single units, with bigger plant phased. If you can send pictures, we can arrive in Sullington knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Clear loose items from the work area
- Let us know about parking and loading
How to get a quote
To help us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or send us an email.

Fixed quotes for AHU cleaning in Sullington
The diagnosis comes before the price. The main factors are:
- The size of the system
- Travel, parking and unloading
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your last certificate, test record or report
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Why act early in Sullington
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. With notice, the visit to Sullington can be fitted around your bookings and events.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

When it’s something else

- Building management system faults
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly.

Other services in Sullington
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Managing agents and facilities teams in Sullington
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.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
