About our AHU cleaning in Haddenham
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. Typical jobs include units that have only ever had filter changes and blocked condensate drains and slimy trays, on filter sections, internal panels and heating and cooling coils.
Smaller buildings around Haddenham often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. We plan the journey to Haddenham and bring what the job is likely to need.
- We survey the unit from photos 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
- Let us know about permits to work or site inductions
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
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.
Advice
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the area around the fresh air intake clear
- Plan the next inspection before the last report gets filed away
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
For landlords and multi-site operators
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.
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 pictures, so each one has its own record.
FAQs for Haddenham
Do you work in villages like Haddenham?
Yes, we work in villages as well as towns, and Haddenham is covered. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Haddenham?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Is a quote from photos possible?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
What should I send you?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Do you need AHU cleaning in Haddenham?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Clients normally contact us after spotting something like this:
- Drain trays holding standing water
- Odours coming through the supply air
- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
School buildings such as Haddenham Community Infant School are typically done in the holidays, so classrooms are not disturbed.
