About our AHU cleaning in Dagenham Dock
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you’re dealing with coils clogged with dust and debris and plant that has been serviced but not cleaned, we can help, from supply and extract fans, internal panels and heating and cooling coils onwards.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Dagenham Dock is often done in the evening or at weekends. Loading and parking are planned with the building first.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Ventilation in Dagenham Dock buildings
Going by the FSA’s register, there are about 22 schools, colleges and universities and about 13 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Dagenham Dock. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Ventilation cleaning in London buildings is usually planned for evenings or weekends. The nearest hospital to Dagenham Dock is Barking Community Hospital, about 2.3 miles north-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
School buildings such as St Peter's Catholic Primary School are normally done in the holidays, so classrooms are not disturbed. If you manage offices or shops near Dagenham Dock station, their ventilation can be inspected and cleaned out of hours.

Common questions in Dagenham Dock
Can parking be tricky for a job in Dagenham Dock?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Can a school’s ventilation in Dagenham Dock be done out of term time?
Yes, holiday work suits schools best. There are about 22 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Dagenham Dock. Just ring 0345 646 2711 or email us with your term dates and we’ll plan around them.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Is Dagenham Dock in your area?
Yes. We work in Dagenham Dock and across Greater London, within our South East and London area. For a fixed quote, phone us on 0345 646 2711 or use the quote form.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or email us.
Can you come out in an emergency?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
What we do, step by step
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. In a London area like Dagenham Dock, parking, loading and building access are planned before the day of the work.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Advice
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Honest limits
In fairness, there are a few things this work won’t fix:
- Problems with the unit’s controls or sensors
- A system that is undersized for the building
- The supply and extract ducts, quoted separately
If in doubt, ring 0345 646 2711 or drop us a line and we’ll say what we think before you book.
What we work on in Dagenham Dock

- Drain trays
- Dampers and louvres

What staff can safely do
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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
What the work involves, part by part
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.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
When to call us in Dagenham Dock
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
- Odours coming through the supply air
- Dust built up on fan impellers
Healthcare ventilation, from large hospitals like Barking Community Hospital (about 2.3 miles north-west) to small clinics, depends on clean filters, coils and ducts.
