AHU cleaning in Sewardstonebury
Our AHU cleans for sites in Sewardstonebury cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. We are often asked to deal with dirty coils holding back the airflow and drain trays holding standing water, across filter sections, supply and extract fans and drain trays.
Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Sewardstonebury, as elsewhere, cleaning starts with an inspection of what’s there.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
How the visit works
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. For a job in Sewardstonebury, tell us about loading bays, permits, lifts and roof access when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive

Sewardstonebury: your questions answered
Can a school’s ventilation in Sewardstonebury be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 10 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Sewardstonebury. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Does London parking affect a job in Sewardstonebury?
A loading bay, a visitor permit or off-street space near the site in Sewardstonebury makes the visit easier to plan. If the building has a loading slot system, we will book into it.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711, or send details by email with the site type, opening hours and a few photos.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
What your team can do, and what needs us
Staff cleaning doesn’t 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.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

What AHU cleaning cannot fix
We’ll always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.
What the work covers

Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
- Change filters on schedule and log each change
- Report water on the plant room floor
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
