Upminster: your questions answered
Can a school’s ventilation in Upminster be done out of term time?
Yes, and it’s the easiest time to do it. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Upminster. You can call us on 0345 646 2711, or email photos with the dates the site is empty.
Can you work in Upminster outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Upminster does not have to lose a day’s trading. Your opening times are the first thing we ask for.
What does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Can you quote from pictures?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How we handle AHU cleaning in Upminster
Our AHU cleaning covers sites in Upminster and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have dirty fans and fan housings and filters that are clogged or overdue, we can put it right.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Upminster is usually planned out of hours. Parking and loading are agreed with the building in advance.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What affects the quote in Upminster
Your quote is based on your site. We take into account:
- Working hours and out-of-hours timing
- The number of sites or systems
- Whether we need access equipment or extra panels
- What state the system is in
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

- Photos showing the whole system and its surroundings

Signs you need AHU cleaning in Upminster
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Clients usually contact us after spotting one of these:
- Condensate trays that won’t empty
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
- Filters that are clogged or overdue
Healthcare ventilation, from large hospitals like St George's Hospital (about 1.7 miles south-west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- What hours they’ll be on site
- Proof of insurance
- What happens if part of the system can’t be accessed
- Proof of accreditation you can verify
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Upminster.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Have your last certificate or report to hand
- Move anything stored near the system
- Name a contact who can let us in at the agreed time
Get a fixed quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, ring 0345 646 2711, or send details by email.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- Clear leaves and litter away from the intake
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
- Don’t ignore odours coming through the grilles
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What your team can do, and what needs us
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.
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 they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What AHU cleaning looks like in Upminster
Food Standards Agency data includes about 21 schools, colleges and universities and about 36 hospitals, care homes and childcare premises within about 1.5 miles of central Upminster. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. St George's Hospital is the nearest hospital, about 1.7 miles south-west of Upminster. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.
For schools like Upminster Junior School, the holidays are the usual time to inspect and clean ventilation. Workplaces around Upminster station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
