AHU cleaning in Barking
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. Common call-outs are for blocked condensate drains and slimy trays and intake sections clogged with outdoor debris, across supply and extract fans, heating and cooling coils and internal panels.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Barking is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Why it’s worth doing now in Barking
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Choosing the date yourself beats having a fault choose it for you.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

What else we do in Barking
What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- What state the system is in
- How many systems or sites are involved
- Site requirements such as sign-in and permits
- The times the site is available
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
What to send for a quote
You do not need the technical terms. It helps if you can send:
- Where the site is and what kind of site it is
- Any previous report or certificate
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
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.
Questions from Barking
Does London parking affect a job in Barking?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, normally makes it simpler.
Do you work overnight in Barking?
Yes, we can come after you close and finish before you open. That way a site in Barking doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Can you quote from pictures?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
If you are not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before you book.
What the work covers
- Supply and extract fans
- Internal panels
- Drain trays
- Filter sections
- Heating and cooling coils
- Dampers and louvres
What happens on the day
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Most London sites cannot stop for the day, so work in Barking is normally done overnight, early in the morning or at weekends.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Let us know about permits to work or site inductions
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive

Advice
Ventilation in Barking buildings
Food Standards Agency data includes about 34 schools, colleges and universities, about 36 care, childcare and hospital premises and about 4 hotels and guest houses within about 1.5 miles of central Barking. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. London plant rooms are often on roofs or in basements reached through occupied floors. Barking Community Hospital is the nearest hospital, about under half a mile north of Barking. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage a school such as Eastbury Primary School, ventilation cleaning is best booked for the holidays. Healthcare ventilation, from large hospitals like Barking Community Hospital (about less than half a mile north) to small clinics, depends on clean filters, coils and ducts.
