AHU cleaning for kitchens and businesses in Laleham
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers internal panels, filter sections and heating and cooling coils, and common reasons people get in touch are air handling units never cleaned inside and odours coming through the supply air.
Around a place like Laleham, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What we are called out for in Laleham
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Keep an eye out for any of the following:
- Debris and leaves in the fresh air intake
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
Ashford Hospital, about 2 miles north-east, is the nearest hospital to Laleham, and healthcare sites of every size need their supply air kept clean.
What to look for in a quote
- Whether they’re fully insured
- What happens if part of the system cannot be accessed
- If the quote is a fixed price or an estimate
- What records you will receive afterwards
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
- Report musty smells from the vents straight away
- Watch for drips or damp patches near the plant
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.

AHU cleaning around Laleham
There are about 12 schools, colleges and universities and about 13 care, childcare and hospital premises on the FSA’s food hygiene register in Laleham and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 18 miles out from central London, Laleham is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Laleham’s nearest hospital, Ashford Hospital, is about 2 miles north-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Laleham CofE VA Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Managing agents and facilities teams in Laleham
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Questions from Laleham
Can you clean school ventilation in Laleham during the holidays?
Yes, out-of-term visits are normal for schools. There are about 12 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Laleham. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work in villages like Laleham?
Yes. Villages and rural sites across the South East are part of our work, Laleham included. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Do you work evenings or weekends?
Yes, if daytime working is not practical. We plan the shutdown window with you.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
How it works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. For a site near Laleham, the work is booked around your opening hours, evenings and weekends included.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
