Questions from Little Woodcote
Do you work at weekends in Little Woodcote?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Little Woodcote needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Do you clean school ventilation in Little Woodcote in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 11 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Little Woodcote. You can call 0345 646 2711 or drop us a line with the dates the site is empty.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What about areas you cannot get to?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
How do you protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
About our AHU cleaning in Little Woodcote
Where a building in Little Woodcote has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you have fan sections that haven’t been cleaned in years and leaves and litter drawn into the unit, we can put it right, from supply and extract fans, dampers and louvres and heating and cooling coils onwards.
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 Little Woodcote, dust settles in the units and ducts year after year.
We’ve been trading since 2009, as 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.

What staff can safely do
Staff cleaning and specialist work are not the same thing. 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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Fixed quotes for AHU cleaning in Little Woodcote
The price is fixed before any work begins. It takes into account:
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
- The times the site is available
- What state the system is in
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
What to send for a quote
Before you ask for a quote, gather:
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings
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.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Don’t ignore odours coming through the grilles
- File each AHU report in the maintenance log
- Report water on the plant room floor
- Change filters on schedule and log each change
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.

Part by part
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.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
When something else is needed
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Problems with the unit’s controls or sensors
- The supply and extract ducts, quoted separately
- Mechanical faults with motors, belts or bearings
If in doubt, call us on 0345 646 2711 or use the quote form and we will say what we think.
