Can the work in Bush Hill Park be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Bush Hill Park can fit around your hours. Your opening times are the first thing we ask for.
Can a school’s ventilation in Bush Hill Park be done out of term time?

Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Do you cover Bush Hill Park?
Yes. Bush Hill Park is part of the area we cover, as part of our area across London and the South East.
Is a quote from pictures possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
AHU cleaning in Bush Hill Park
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers heating and cooling coils, drain trays and supply and extract fans, and common reasons people get in touch are debris and leaves in the fresh air intake and condensate trays that won’t empty.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Bush Hill Park, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Why deal with it now?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. A building in Bush Hill Park may have flats or offices above and alongside, and a fault in the system can affect them too.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

What the work involves, part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Common problems we fix in Bush Hill Park
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Look out for any of the following:
- Condensate trays that won’t empty
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Air handling units never cleaned inside
For workplaces around Bush Hill Park station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Questions to ask before booking
- Whether the work can be done while the site is closed
- Whether the price is fixed
- What paperwork you get at the end
- How they set the interval to the next visit
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed 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. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Bush Hill Park.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in

Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report musty smells from the vents right away
- Keep the area around the fresh air intake clear
- Note any water around the unit or leaks below it
- File each AHU report in the maintenance log
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
