AHU cleaning for kitchens and businesses in Keston
Our AHU cleaning covers sites in Keston and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with condensate trays that won’t empty and dirty fans and fan housings, on dampers and louvres, supply and extract fans and internal panels.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Keston, dust and debris build up in the units and ductwork over time.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

AHU cleaning in Keston: local notes
The FSA’s food hygiene register lists about 5 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within 1.5 miles or so of the middle of Keston. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About 1.1 miles east of Keston is Princess Royal University Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Keston, clean ventilation matters as much to you as to a hospital like Princess Royal University Hospital (about 1.1 miles east).

How it works
Your trading hours come first. 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 job takes one overnight shift for many single units, with bigger plant phased. In a London area like Keston, parking, loading and building access are planned before the day of the work.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms

Advice
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- The times the site is available
- The condition of the system
- The scale of the work
- How easy every part is to reach
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.
Helping us quote
When you call or email, it’s useful to have:
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Wide photos of the system and the area around it
Getting a quote doesn’t take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Staff cleaning versus specialist work
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 they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right 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 will take a look and give you a fixed quote.
FAQs for Keston
Is parking a problem for work in Keston?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, typically makes it simpler.
Can you work in Keston outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Do you work in Keston?
Yes. Our technicians work in Keston, as part of our area across London and the South East.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
Do you need AHU cleaning in Keston?
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Keston, that is air they breathe for hours at a time.
Clients typically contact us when they notice one of these:
- Units that have only ever had filter changes
- Blocked condensate drains and slimy trays
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
School buildings such as Keston Church of England Primary School are typically done in the holidays, so classrooms aren’t disturbed.
Before you book anyone
- Whether the figure could change on the day
- Whether the whole system is included, or only the parts that are easy to reach
- If they look at the system before pricing
- Whether the work can be done while the site is closed
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- A system that’s undersized for the building
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think.
Where we work
- Internal panels
- Supply and extract fans
- Drain trays
- Filter sections
- Dampers and louvres
- Heating and cooling coils
How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Managing agents and facilities teams in Keston
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
