- Coils that are corroded or leaking and need replacing

AHU cleaning for kitchens and businesses in Quidhampton
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. Common call-outs are for dirty fans and fan housings and plant that needs cleaning after a refit, on supply and extract fans, internal panels and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
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.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Quidhampton: your questions answered
Do you offer AHU cleaning in Quidhampton?
Yes. Our area runs across London and the South East, Quidhampton included. Just call 0345 646 2711 or drop us a line with a few details of the site.
Can the work in Quidhampton be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Quidhampton doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
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, and TR19® Air covers general supply and extract systems.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Quidhampton.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear the space around the work
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one

Related advice
Do you need AHU cleaning in Quidhampton?
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
Keep an eye out for these warning signs:
- Air handling units due a clean after building work
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
Classrooms and halls at schools such as Overton Church of England Primary School are easiest to work in when pupils are away.
What your quote should include
- What paperwork you get at the end
- When they can work, and whether that’s outside your opening hours
- Whether a survey comes first
- How areas they can’t reach will be recorded
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. In a place like Quidhampton, ductwork and fans are easy to forget until something goes wrong.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Where the site is and how we reach it
- How easy every part is to reach
- How many systems or sites are involved
- A single visit or a regular plan
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- The site address and the type of premises
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Managing agents and facilities teams in Quidhampton
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
