Woodford Wells buildings and their air
Food Standards Agency data includes about 28 schools, colleges and universities and about 44 care, childcare and hospital premises within 1.5 miles or so of the middle of Woodford Wells. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. About 1.7 miles south-east of Woodford Wells is Claybury Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Healthcare buildings such as Claybury Hospital, about 1.7 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Woodford Wells, yours matters too.

About our AHU cleaning in Woodford Wells
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you are dealing with drain trays holding standing water and units needing a clean before a new tenant or handover, we can help.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Woodford Wells, dust and debris build up in the units and ductwork over time.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Your questions about AHU cleaning in Woodford Wells
Does London parking affect a job in Woodford Wells?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we’ll book into it.
Can a school’s ventilation in Woodford Wells be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 28 schools and colleges with food registrations within roughly a mile and a half of Woodford Wells. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll normally reply within one working day.
What’s included in an AHU clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. A name and number for whoever controls access to the building in Woodford Wells saves time on the night.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- 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
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- One-off work versus a regular cycle
- How easy every part is to reach
- Site requirements such as sign-in and permits
- Travel, parking and unloading
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What we need to know
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Your opening hours and when the area is out of use
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
Why it’s worth doing now in Woodford Wells
Stuffy rooms and stale smells in a building in Woodford Wells can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Every month a London system goes without attention adds to what has to be done later.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

When something else is needed
A few issues sit outside what this work can do:
- Leaking heating or cooling coils
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly.
Where we work
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Drain trays
- Internal panels
- Filter sections
What staff can safely do
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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

When to call us in Woodford Wells
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
For schools like Wells Primary School, the holidays are the usual time to inspect and clean ventilation.

Different parts, different methods
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
