The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Twyford, tell us about narrow lanes, gates and parking when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.

AHU cleaning for kitchens and businesses in Twyford
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you have drain trays holding standing water and rooms that smell stuffy when the system runs, we can help, from dampers and louvres, internal panels and heating and cooling coils onwards.
In a village or hamlet like Twyford, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
When something else is needed
A few issues sit outside what this work can do:
- Controls and BMS settings that run the unit
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
If you’re not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.

Fixed quotes for AHU cleaning in Twyford
There’s no set price list, because no two systems are the same. What we look at:
- The condition of the system
- How many systems or sites are involved
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
When you call or email, it’s useful to have:
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to

For landlords and multi-site operators
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 send the paperwork to whoever needs it.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
FAQs for Twyford
Do you cover smaller places like Twyford?
Yes. Villages and rural sites across the South East are part of our work, Twyford included. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you clean school ventilation in Twyford during the holidays?
Yes. The holidays are the usual time for school work. Around Twyford, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

Do you need AHU cleaning in Twyford?
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 Twyford, that is air they breathe for hours at a time.
Most sites get in touch when they notice one of these:
- Blocked condensate drains and slimy trays
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Dust-coated heating and cooling coils
If you run an office near Shawford station, its supply ductwork can gather dust for years before anyone looks inside.
