AHU cleaning in Great Braxted
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, heating and cooling coils and filter sections, and people most often call us about fan sections that haven’t been cleaned in years and coils clogged with dust and debris.
Somewhere as small as Great Braxted, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
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.

Landlords, agents and facilities managers
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- The condition we find in the survey
- Whether we need access equipment or extra panels
- The times the site is available
- Parking and loading at the site
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to

Great Braxted: your questions answered
Do you work at weekends in Great Braxted?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Great Braxted needn’t be disturbed. Your opening times are the first thing we ask for.
Is Great Braxted in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Great Braxted included. Just ring 0345 646 2711 or use the quote form with a few details of the site.
Can you quote from photos?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What does TR19 mean?
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 we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
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 pictures.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Between visits
Think of this as the after-treatment advice, short and simple:
- Make sure condensate is draining away
- Don’t store bins or materials near the intake
- Report water on the plant room floor
- Report musty smells from the vents straight away
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

What the work involves, part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
How the visit works
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 anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Great Braxted and turn up when the site is quiet.
- 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, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Find the previous report, if there is one
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
