What AHU cleaning looks like in Upper Clapton
Going by the FSA’s register, there are about 33 schools, colleges and universities and about 38 hospitals, care homes and childcare premises serving food within about 1.5 miles of central Upper Clapton. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Homerton University Hospital is the nearest hospital, about 1.5 miles south of Upper Clapton. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage offices or shops near Clapton station, their ventilation can be inspected and cleaned out of hours. If you manage a school such as Harrington Hill Primary School, ventilation cleaning is best booked for the holidays.

About our AHU cleaning in Upper Clapton
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. We’re often asked to deal with blocked condensate drains and slimy trays and dust-coated heating and cooling coils, on supply and extract fans, dampers and louvres and drain trays.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Upper Clapton, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why act early in Upper Clapton
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. In Upper Clapton, as across London, ductwork often passes through shared risers and other people’s space.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Questions from Upper Clapton
Can the work in Upper Clapton be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Upper Clapton keeps running as normal. When you call us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Do you clean school ventilation in Upper Clapton in the holidays?
Yes, holiday work suits schools best. There are about 33 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Upper Clapton. Booking early in the term gives the best choice of holiday dates.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. A fixed quote follows.
Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Facilities teams in offices, schools and healthcare sites book us too in Upper Clapton and across Greater London. Larger estates can be phased building by building to keep disruption down.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. A name and number for whoever controls access to the building in Upper Clapton saves time on the night.
- 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.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
How to get a quote
To get a fixed quote, phone us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

What affects the cost of AHU cleaning
You will get a fixed price before we start. It’s based on:
- Working hours and out-of-hours timing
- How big the system is
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep the area around the fresh air intake clear
- Report musty smells from the vents straight away
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Common problems we fix in Upper Clapton
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Keep an eye out for these warning signs:
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
Healthcare buildings such as Homerton University Hospital, about 1.5 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Upper Clapton, yours matters too.
What to look for in a quote
- Proof of accreditation you can verify
- Whether a written report and photos are included
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they recommend a next date
What your team can do, and what needs us
Staff cleaning doesn’t 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.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
