Highgate AHU cleaning
Need AHU cleaning in Highgate? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Condensate trays that will not empty
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
How we handle AHU cleaning in Highgate
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have dust-coated heating and cooling coils and dust built up on fan impellers, we can put it right.
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 Highgate.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Highgate buildings and their air
Food Standards Agency data includes about 34 schools, colleges and universities, about 47 hospitals, care homes and childcare premises and about 5 hotels and guest houses within roughly a mile and a half of the centre of Highgate. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. Highgate Private Hospital is the nearest hospital, about 0.6 miles north-west of Highgate. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Healthcare buildings such as Highgate Private Hospital, about 0.6 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Highgate, yours matters too. Workplaces around Upper Holloway station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you manage a school such as St Michael's Church of England Primary School, ventilation cleaning is best booked for the holidays.

Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Report stiff or damaged access doors
- Book the next check in line with the report
- Watch for drips or damp patches near the plant
- Clear leaves and litter away from the intake
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What the work involves, part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Common questions in Highgate
Do you clean school ventilation in Highgate in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 34 schools, colleges and universities with registered kitchens within about a mile and a half of Highgate. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you come to Highgate after we close?
Yes, we can come after you close and finish before you open. The work in Highgate can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Security desks and permits-to-work are routine in London, so let us know what your building in Highgate needs from us.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Have your last certificate or report to hand
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
