AHU cleaning for kitchens and businesses in Upper Farringdon
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 filters that are clogged or overdue and fan sections that haven’t been cleaned in years, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Fixed quotes for AHU cleaning in Upper Farringdon
Your quote is based on your site. We take into account:
- Whether several sites go on one quote
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

Questions from Upper Farringdon
Can you do AHU cleaning in Upper Farringdon?
Yes, Upper Farringdon is within the area we cover across London and the South East. You can call us on 0345 646 2711 or use the quote form and let us know what needs doing.
Can you get to a site in Upper Farringdon?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Does the AHU have to be shut down for cleaning?
Yes, for the time we are working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
What staff can safely do
Staff cleaning and specialist work aren’t 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. Cleaning inside ducts and units is specialist work.
Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.

Aftercare tips
To keep the system working properly between visits:
- Do not store bins or materials near the intake
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
- Check the drain tray is emptying during routine visits
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Upper Farringdon run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Mention any parking or loading restrictions
- Clear the space around the work
- Let us know when the site is closed or quiet
