About our AHU cleaning in Waterhall
We clean air handling units for buildings in Waterhall and across Brighton and Hove, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers drain trays, internal panels and heating and cooling coils, and common reasons people get in touch are dust built up on fan impellers and air handling units due a clean after building work.
In a village or hamlet like Waterhall, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Waterhall run smoothly.
- 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 are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system

Why it’s worth doing now in Waterhall
Stuffy rooms and stale smells in a building in Waterhall can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. A planned visit to Waterhall is easier to arrange than an emergency callout.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
What you get with us
- CHAS, SafeContractor and ISO 9001
- Full insurance on every job

Waterhall buildings and their air

What a clean will not put right
Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It will not put right:
- Ventilation that was badly designed in the first place
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we’ll tell you honestly.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Waterhall: your questions answered
Will you come out to Waterhall?
Yes. Villages and rural sites across the South East are part of our work, Waterhall included. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Waterhall?
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.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply give us a ring on 0345 646 2711 or email us.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Between visits
Simple habits between visits make a real difference. We recommend:
- Keep the area around the fresh air intake clear
- Do not ignore odours coming through the grilles
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Signs you need AHU cleaning in Waterhall
Whatever surrounds a building in Waterhall, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
What we are most often called out for:
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
If you manage a school such as Westdene Primary School, ventilation cleaning is best booked for the holidays.
