About our AHU cleaning in Oaker Hill
Our AHU cleans for sites in Oaker Hill cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you’re dealing with air handling units due a clean after building work and stale or musty smells from the ventilation, we can put it right, from drain trays, dampers and louvres and filter sections onwards.
For a building in or near Oaker Hill, 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.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
FAQs for Oaker Hill
Can a school’s ventilation in Oaker Hill be done out of term time?
Yes, out-of-term visits are normal for schools. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Oaker Hill. Booking early in the term gives the best choice of holiday dates.
Is Oaker Hill within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Oaker Hill included. Let us know about access, parking and anything unusual about getting there when you book.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What information do you need?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
How long does an AHU clean take?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, and you can phone us on 0345 646 2711 or drop us a line to plan it.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Ventilation in Oaker Hill buildings
Food Standards Agency data includes about 4 schools, colleges and universities in and around Oaker Hill, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Oaker Hill, about 46 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
Wherever a school like St Andrew's Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. An inspection comes first for any ventilation job around Oaker Hill, so the cleaning matches what’s there.

What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Oaker Hill.
- 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.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or email us.
Advice
What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- The size of the system
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or drop us a line.
How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.

Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to Oaker Hill is calmer for everyone.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Make sure the unit’s access doors open easily
- Store the TR19 paperwork where auditors can find it
- Make sure condensate is draining away
- Keep filter changes on time and recorded
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
