AHU Cleaning in South Park
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for businesses, landlords and public buildings in South Park. CHAS, SafeContractor and ISO 9001, and fully insured.
- Condensate trays that won’t empty
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
For landlords and multi-site operators
Records are where multi-site compliance often slips. 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 work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
AHU cleaning for kitchens and businesses in South Park
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Typical jobs include air handling units due a clean after building work and units that have only ever had filter changes, across supply and extract fans, drain trays and dampers and louvres.
In a place like South Park, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Do you need AHU cleaning in South Park?
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Dirty coils holding back the airflow
- Debris and leaves in the fresh air intake
- Dust built up on fan impellers
East Surrey Hospital, about 2 miles east, is the nearest hospital to South Park, and healthcare sites of every size need their supply air kept clean.
Questions to ask before you book
- What paperwork you get at the end
- When the next visit should be, and why
- Whether a survey comes first
- Whether the quote shows VAT
Your questions about AHU cleaning in South Park
Do you cover smaller places like South Park?
Yes. Villages and rural sites across the South East are part of our work, South Park included. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in South Park?
Yes, nights and weekends are routine for us. It means the site in South Park keeps running as normal. When you ring 0345 646 2711 or email us, mention when the site is quiet.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
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. A fixed quote follows.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
What if parts of the system cannot be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.

What affects the quote in South Park
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
What we need to know
We can often survey from photos. The most useful are:
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or use the quote form.
The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Tell us about any gates, ladders or locked plant areas at your site near South Park when you book.
- We survey the unit from photos or on site and agree what’s included.
- 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.
- 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
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
- Find the previous report, if there is one

Advice
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. A planned visit to South Park fits your hours; an emergency doesn’t.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Ventilation in South Park buildings
Food Standards Agency records list about 10 schools, colleges and universities and about 18 care, childcare and hospital premises registered as food businesses in South Park and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. East Surrey Hospital is the nearest hospital, about 2 miles east of South Park. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. South Park is about 20 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
Classrooms and halls at schools such as Sandcross Primary School are easiest to work in when pupils are away.
