Air handling unit cleaning in Roxeth, Greater London
AHU cleaning for commercial sites in Roxeth and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
AHU cleaning for kitchens and businesses in Roxeth
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you’re dealing with dirty coils holding back the airflow and air handling units due a clean after building work, we can put it right, from drain trays, supply and extract fans and dampers and louvres onwards.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Roxeth.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Dirty ducts beyond the unit itself
- Ventilation that was badly designed in the first place
- Breakdowns that need a mechanical engineer
Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
Parts of the system we cover
- Heating and cooling coils

- Drain trays

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Roxeth simpler. London sites work long hours, and the longer a job is left, the bigger it gets.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. Night and weekend working is normal for us in London, and a site in Roxeth is no exception.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Arrange a key holder or contact on site
- Clear the space around the work
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
Some systems can be priced from pictures; 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.
Advice
Ventilation in Roxeth buildings
Going by the FSA’s register, there are about 17 schools, colleges and universities, about 61 care, childcare and hospital premises and about 4 hotels and guest houses serving food within roughly a mile and a half of the centre of Roxeth. Busy, occupied buildings like these are where clean supply air matters most. The nearest hospital to Roxeth is Clementine Churchill Hospital, about 0.7 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Ventilation cleaning in London buildings is typically planned for evenings or weekends.
If you manage shops or offices close to Sudbury Hill Harrow station, a TR19® Air inspection shows whether the ductwork needs cleaning. Wherever a school like Roxeth Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

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.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Common problems we fix in Roxeth
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 Roxeth, that is air they breathe for hours at a time.
It’s time to book a visit if you see:
- Odours coming through the supply air
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Filters that are clogged or overdue
Healthcare buildings such as Clementine Churchill Hospital, about 0.7 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Roxeth, yours matters too.

Questions from Roxeth
Do you work overnight in Roxeth?
Yes, nights and weekends are routine for us. It means the site in Roxeth keeps running as normal. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
Can you clean school ventilation in Roxeth during the holidays?
Yes, and it’s the easiest time to do it. Around Roxeth, the Food Standards Agency lists about 17 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What do you need from me for a quote?
Some photos and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
