Foxbury questions
How do you handle parking and loading in Foxbury?
A loading bay, a visitor permit or off-street space near the site in Foxbury makes the visit easier to plan. Much of our London work is done overnight, which helps.
Do you work at weekends in Foxbury?
Yes, out-of-hours work is a big part of what we do. That way a site in Foxbury does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
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’re fully insured.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
Do you need to switch the unit off?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What should I send you?
A short description and a few pictures, with the address and opening hours. We’ll ask for anything else we need.
About our AHU cleaning in Foxbury
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. Typical jobs include leaves and litter drawn into the unit and filters that are clogged or overdue, on supply and extract fans, heating and cooling coils and internal panels.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Foxbury is typically planned out of hours. Loading and parking are planned with the building first.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

AHU cleaning in Foxbury: local notes
Food Standards Agency data includes about 18 schools, colleges and universities and about 41 care, childcare and hospital premises within 1.5 miles or so of the middle of Foxbury. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Queen Mary's Hospital is the nearest hospital, about 0.6 miles east of Foxbury. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Getting kit to a London plant room usually means lifts, stairs and an agreed loading slot.
Hospitals such as Queen Mary's Hospital (about 0.6 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Foxbury are no different.

How it works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. Expect the work in Foxbury to happen after your last customer leaves, not during trading.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Why deal with it now?
Stuffy rooms and stale smells in a building in Foxbury can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Leaving it on a busy London site only adds to the work.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
Why us?
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fixed quotes, typically within one working day
- We’re fully insured

What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
What we are called out for in Foxbury
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Any of these means the system needs a check-up:
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Units that have only ever had filter changes
- Odours coming through the supply air
For schools like Chislehurst School for Girls, the holidays are the usual time to inspect and clean ventilation.

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
- One-off work versus a regular cycle
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Wide pictures of the system and the area around it
- Any previous report or certificate
We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To start, call us on 0345 646 2711, or send details by email.
