AHU cleaning for kitchens and businesses in Langrish
Our AHU cleaning covers sites in Langrish and the rest of Hampshire, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers internal panels, drain trays and filter sections, and people most often call us about fan sections that haven’t been cleaned in years and rooms that smell stuffy when the system runs.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Do you need AHU cleaning in Langrish?
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Most sites get in touch when they notice one of these:
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
Wherever a school like Langrish Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- Whether the figure could change on the day
- What records you will receive afterwards

Questions from Langrish
Is AHU cleaning available in Langrish?
Yes, Langrish is within the area we cover across London and the South East. Just phone us on 0345 646 2711 or drop us a line with a few details of the site.
Will you come out to Langrish?
Yes. Langrish is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What 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 and tell us about the site and its opening hours.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
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 for your maintenance team to follow up.
What if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Langrish simpler. In a small place like Langrish, a system that fails can take a site out of use.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Whether several sites go on one quote
- The size of the system
- Working hours and out-of-hours timing
- 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 will go through it with you.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- Your last certificate, test record or report
- The site address and the type of premises
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. We agree a date with you, plan the drive to Langrish and turn up when the site is quiet.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
How to get a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, call 0345 646 2711 or drop us a line.
