How we handle AHU cleaning in Badshot Lea
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers filter sections, drain trays and heating and cooling coils, and the jobs we see most are plant that has been serviced but not cleaned and fan sections that haven’t been cleaned in years.
For a building in or near Badshot Lea, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What affects the cost of AHU cleaning
You’ll get a fixed price before any work starts. It takes into account:
- The size of the system
- Any permits to work or inductions
- Parking and loading at the site
- A single visit or a regular plan
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted

Do you need AHU cleaning in Badshot Lea?
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Look out for these warning signs:
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
- Air handling units due a clean after building work
Healthcare ventilation, from large hospitals like Fleet Community Hospital (about 5.4 miles north-west) to small clinics, depends on clean filters, coils and ducts.

Questions from Badshot Lea
Can you get to a site in Badshot Lea?
Yes. Badshot Lea is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can a school’s ventilation in Badshot Lea be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 21 schools and colleges with food registrations within roughly a mile and a half of Badshot Lea. Tell us your holiday dates and we will book the visit for when the site is empty.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.

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. Our emergency line runs 24/7, but a planned visit to Badshot Lea is calmer for everyone.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

What else we do in Badshot Lea
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Badshot Lea before we set off.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Tell us about site rules, permits or sign-in

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Keeping the system healthy
Once we have finished, these simple steps help:
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
