About our AHU cleaning in Highbury
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you’re dealing with debris and leaves in the fresh air intake and units needing a clean before a new tenant or handover, we can help.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Highbury, as elsewhere, cleaning starts with an inspection of what’s there.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. A booked night’s work in Highbury costs you no trading time; an unplanned closure does.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Different parts, different methods
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Common problems we fix in Highbury
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Most sites get in touch when they notice something like this:
- Leaves and litter drawn into the unit
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
- Units needing a clean before a new tenant or handover
King's College Hospital Charity, about 1.1 miles south-west, is the nearest hospital to Highbury, and healthcare sites of every size need their supply air kept clean.

Highbury questions
Is parking a problem for work in Highbury?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Can ventilation in schools around Highbury be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 31 schools and colleges with food registrations within roughly a mile and a half of Highbury. Booking early in the term gives the best choice of holiday dates.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Highbury and across Greater London. Larger estates can be phased building by building around the people who use them.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
AHU cleaning in Highbury: local notes
There are about 31 schools, colleges and universities, about 58 caring premises (care homes, nurseries and hospitals) and about 7 hotels and B&Bs on the FSA’s food hygiene register across Highbury and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. London plant rooms are often on roofs or in basements reached through occupied floors. About 1.1 miles south-west of Highbury is King's College Hospital Charity, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Workplaces around Canonbury station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. School buildings such as Highbury Quadrant Primary School are typically done in the holidays, so classrooms are not disturbed.

How the visit 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. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes half a day to a full day per unit, with large plant planned over several shifts. Night and weekend working is normal for us in London, and a site in Highbury is no exception.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand
Ask for a quote
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, the quote is fixed before any work is booked.
