How we handle AHU cleaning in Oakthorpe Park
A cooling coil drips condensate into a tray that should drain away. 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. If you’re dealing with dirty coils holding back the airflow and drain trays holding standing water, we can help, from heating and cooling coils, internal panels and filter sections onwards.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Oakthorpe Park, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Oakthorpe Park
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Look out for any of the following:
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
Classrooms and halls at schools such as St Anne's Catholic High School for Girls are easiest to work in when pupils are away.
Questions to ask before you book
- Whether the figure could change on the day
- How areas they can’t reach will be recorded
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When they can work, and whether that is outside your opening hours
Honest limits
It’s worth knowing the limits before booking:
- A system that is undersized for the building
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think.

Fixed quotes for AHU cleaning in Oakthorpe Park
The quote reflects the site in front of us. We consider:
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The site address and the type of premises
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
For a fixed quote, ring 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You’ll typically have a quote within one working day.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What happens on the day
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. Security desks and permits-to-work are routine in London, so let us know what your building in Oakthorpe Park needs from us.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Have your last certificate or report to hand
- Clear loose items from the work area
- Mention any parking or loading restrictions
Ask for a quote
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 many jobs can be priced from that alone.
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
- File each AHU report in the maintenance log
- Report musty smells from the vents straight away
- Plan the next inspection before the last report gets filed away
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
