AHU cleaning for kitchens and businesses in Charlton
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. Common call-outs are for odours coming through the supply air and units that have only ever had filter changes, across heating and cooling coils, dampers and louvres and drain trays.
Visits to a place like Charlton are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

FAQs for Charlton
Will you come out to Charlton?
Yes. Charlton is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you do school ventilation cleaning in Charlton in the summer holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 8 schools and colleges with food registrations within roughly a mile and a half of Charlton. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and there’s a 24/7 line for emergencies.
Common problems we fix in Charlton
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Keep an eye out for these warning signs:
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
- Plant that needs cleaning after a refit
- Condensate trays that won’t empty
Ventilation work in and around Charlton is risk-based: inspect, then clean what needs it.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- Whether a written report and pictures are included
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether they’re fully insured
What AHU cleaning looks like in Charlton
The FSA’s food hygiene register lists about 8 schools, colleges and universities and about 10 hospitals, care homes and childcare premises with registered kitchens or food service in Charlton and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Charlton, about 57 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
For schools like Charlton Primary School, the holidays are the usual time to inspect and clean ventilation.

What a clean will not put right
Before you book, it helps to know what’s not included:
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
- Coils that are corroded or leaking and need replacing
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
Where we work
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Internal panels
- Supply and extract fans
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
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.
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. A planned visit to Charlton fits your hours; an emergency does not.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711, or send details by email, and we will explain what it covers.

Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Aftercare tips
To keep the system working properly between visits:
- Do not store bins or materials near the intake
- File each AHU report in the maintenance log
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. Visits to a place like Charlton are planned ahead, so we arrive with what the survey says the job needs.
- The survey covers the unit, its access and how it can be shut down.
- 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
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
