What affects the quote in Turnham Green
We don’t publish a price list, because sites vary so much. The quote depends on:
- What state the system is in
- The scale of the work
- Whether several sites go on one quote
- A single visit or a regular plan
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What we need to know
When you contact us, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
How we handle AHU cleaning in Turnham Green
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers drain trays, dampers and louvres and supply and extract fans, and common reasons people get in touch are fan sections that haven’t been cleaned in years and intake sections clogged with outdoor debris.
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. In a building in Turnham Green, dust and debris build up in the units and ductwork over time.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, and that takes one overnight shift for many single units, with bigger plant phased. Expect the work in Turnham Green to happen after your last customer leaves, not during trading.
- We survey the unit from photos or on site and agree what’s included.
- 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.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then phone us on 0345 646 2711 or drop us a line.

When to call us in Turnham Green
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Keep an eye out for any of the following:
- Leaves and litter drawn into the unit
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
Workplaces around Chiswick station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Questions to ask before you book
- If they look at the system before pricing
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- Proof of accreditation you can verify
What happens if it’s left?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A busy site in Turnham Green builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Why us?
- Full insurance on every job
- A fixed price before any work starts
- One number for every site across the South East and London
- CHAS, SafeContractor and ISO 9001

Turnham Green: your questions answered
Do you work at weekends in Turnham Green?
Yes, evening, overnight and weekend work is normal for us. That way a site in Turnham Green does not have to lose a day’s trading. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you clean school ventilation in Turnham Green in the holidays?
Yes, holiday work suits schools best. Around Turnham Green, the Food Standards Agency lists about 47 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you price the work without visiting?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
