How we handle AHU cleaning in Stratford
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, heating and cooling coils and dampers and louvres, and common reasons people get in touch are units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Stratford.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

AHU cleaning in Stratford: local notes
Food Standards Agency data includes about 51 schools, colleges and universities, about 65 care, childcare and hospital premises and about 17 hotels and guest houses within about 1.5 miles of central Stratford. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About within half a mile east of Stratford is Queen Mary's Hospital for the East End, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.
For workplaces around Stratford (London) station with mechanical ventilation, cleaning can be done in the evening or at weekends.

What affects the quote in Stratford
We do not publish a price list, because sites vary so much. The quote depends on:
- How easy every part is to reach
- The number of sites or systems
- A single visit or a regular plan
- Site rules, permits and inductions
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 unsure, call 0345 646 2711 or email us for straight advice and a fixed quote.
Asking for a quote
To help us quote quickly, please include:
- The paperwork from the last visit, if you have it
- Wide photos of the system and the area around it
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, call 0345 646 2711 or send us an email.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
What we are called out for in Stratford
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
What we’re most often called out for:
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
- Odours coming through the supply air
Queen Mary's Hospital for the East End, about under half a mile east, is the nearest hospital to Stratford, and healthcare sites of every size need their supply air kept clean.

Common questions in Stratford
Can parking be tricky for a job in Stratford?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
Can you work in Stratford outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Stratford keeps running as normal. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Can you price the work without visiting?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
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.

How the visit works
Every visit runs to the same pattern: sheeting and protection first, 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. In a London area like Stratford, parking, loading and building access are planned before the day of the work.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
Get a fixed quote
To get a fixed quote, phone us on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will usually have a quote within one working day.

Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Book the next check in line with the report
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
