AHU cleaning in Totteridge
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have dirty filters cutting the airflow and leaves and litter drawn into the unit, we can help.
Around a place like Totteridge, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

When it’s something else
Before you book, it helps to know what’s not included:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Ductwork downstream of the unit, which is a separate clean
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
Parts of the system we cover
- Dampers and louvres
- Filter sections
- Internal panels
- Heating and cooling coils
- Drain trays
- Supply and extract fans
Different parts, different methods
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.
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.
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. In a place like Totteridge, we fit the visit around your hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- 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
- Move anything stored near the system
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time

What staff can safely do
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, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. A site near Totteridge that has to close at short notice is hard to cover for.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.

AHU cleaning around Totteridge
Food Standards Agency data includes about 23 schools, colleges and universities, about 32 care, childcare and hospital premises and about 3 hotels, B&Bs and guest houses within 1.5 miles or so of the middle of Totteridge. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. We cover Totteridge, about 29 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. About 0.9 miles west of Totteridge is Hospital of St John the Baptist, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage a school such as Highcrest Academy, ventilation cleaning is best booked for the holidays. If you manage offices or shops near High Wycombe station, their ventilation can be inspected and cleaned out of hours.

What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- Working hours and out-of-hours timing
- Travel, parking and unloading
- How big the system is
- How easy every part is to reach
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before we start.
Helping us quote
We can often survey from photos. The most useful are:
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- A few general shots of the system
- The postcode and the type of business
Some systems can be priced from pictures; 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.
Totteridge questions
Can you come to Totteridge after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just phone us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Can you clean school ventilation in Totteridge during the holidays?

Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What information do you need?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Common problems we fix in Totteridge
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Most sites get in touch after spotting one of these:
- Stale or musty smells from the ventilation
- Plant that has been serviced but not cleaned
- Drain trays holding standing water
- Dirty filters cutting the airflow
Hospitals such as Hospital of St John the Baptist (about 0.9 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Totteridge are no different.
