AHU cleaning for kitchens and businesses in Moor Park
We clean air handling units for buildings in Moor Park and across Greater London, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and common reasons people get in touch are blocked condensate drains and slimy trays and stale or musty smells from the ventilation.
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 Moor Park, dust settles in the units and ducts year after year.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Your questions about AHU cleaning in Moor Park
Can you work in Moor Park outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Moor Park needn’t be disturbed. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
Do you do school ventilation cleaning in Moor Park in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 14 schools and colleges on the FSA’s register within roughly a mile and a half of Moor Park, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How do you protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
What AHU cleaning looks like in Moor Park
The FSA’s food hygiene register lists about 14 schools, colleges and universities and about 20 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service across Moor Park and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. The nearest hospital to Moor Park is Mount Vernon Hospital, about 0.7 miles south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.
Healthcare ventilation, from large hospitals like Mount Vernon Hospital (about 0.7 miles south-west) to small clinics, depends on clean filters, coils and ducts.

Fixed quotes for AHU cleaning in Moor Park
Your quote is based on your site. We take into account:
- Travel, parking and unloading
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What we need to know
To speed up the quote, send us:
- Your last certificate, test record or report
- The site address and the type of premises
- The times we could work without disrupting the site
- A few general shots of the system
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Signs you need AHU cleaning in Moor Park
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Any of these means the system needs a check-up:
- Dust built up on fan impellers
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
- Dust-coated heating and cooling coils
If you manage a school such as St Martins School Northwood, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- Whether VAT is included
- What paperwork you get at the end
- How areas they cannot reach will be recorded
- Whether they recommend a next date
Managing agents and facilities teams in Moor Park
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Moor Park simpler. Leaving it on a busy London site only adds to the work.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

How the visit works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Night and weekend working is normal for us in London, and a site in Moor Park is no exception.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
For a fixed quote, ring 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We typically come back within one working day.

Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
