Greater London · Air handling unit cleaning
AHU Cleaning in Rotherhithe
We cover Rotherhithe for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
AHU cleaning for kitchens and businesses in Rotherhithe
If the units serving a building in Rotherhithe have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers filter sections, internal panels and drain trays, and the jobs we see most are plant that needs cleaning after a refit and blocked condensate drains and slimy trays.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Rotherhithe, dust and debris build up in the units and ductwork over time.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. In Rotherhithe, a planned overnight visit is much easier than closing unexpectedly.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.

What else we do in Rotherhithe
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Report water on the plant room floor
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What happens on the day
Every visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes one overnight shift for many single units, with bigger plant phased. Expect the work in Rotherhithe to happen after your last customer leaves, not during trading.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

Fixed quotes for AHU cleaning in Rotherhithe
There’s no set price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- Where the site is and how we reach it
- The condition we find in the survey
- Whether we need access equipment or extra panels
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or send us an email for straight advice and a fixed quote.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Wide pictures of the system and the area around it
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Ventilation in Rotherhithe buildings
There are about 87 schools, colleges and universities, about 65 caring premises (care homes, nurseries and hospitals) and about 15 hotels and guest houses on the FSA’s food hygiene register within 1.5 miles or so of the middle of Rotherhithe. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 0.5 miles west of Rotherhithe is St Olave's Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. London plant rooms are often on roofs or in basements reached through occupied floors.
If you run an office near Canada Water station, its supply ductwork can gather dust for years before anyone looks inside. For schools like Alfred Salter Primary School, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near Rotherhithe, clean ventilation matters as much to you as to a hospital like St Olave's Hospital (about 0.5 miles west).
Rotherhithe is about 2 miles south-east of Whitechapel, in Greater London. Whether your site is in the middle of Rotherhithe or further out, we cover AHU cleaning for every kind of premises, from a single unit to a large public building.

For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
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.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Rotherhithe: your questions answered
Can you clean school ventilation in Rotherhithe during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 87 schools and colleges with food registrations within roughly a mile and a half of Rotherhithe. You can give us a ring on 0345 646 2711 or email us with the dates the site is empty.
Is parking a problem for work in Rotherhithe?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
How long does an AHU clean take?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can call 0345 646 2711, or email photos to plan it.
