How we handle AHU cleaning in Clavering
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you are dealing with plant that has been serviced but not cleaned and intake sections clogged with outdoor debris, we can help.
For a building in or near Clavering, 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.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
AHU cleaning around Clavering
The FSA’s food hygiene register lists about 3 schools, colleges and universities with registered kitchens or food service within roughly a mile and a half of the centre of Clavering. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. At about 34 miles from central London, Clavering sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
School buildings such as Clavering Primary School are normally done in the holidays, so classrooms are not disturbed.

How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. For a village or hamlet like Clavering, tell us about narrow lanes, gates and parking when you book.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
What we are called out for in Clavering
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
What we are most often called out for:
- Units that have only ever had filter changes
- Units needing a clean before a new tenant or handover
- Odours coming through the supply air
- Condensate trays that will not empty
For buildings in and around Clavering, TR19® Air cleaning starts with an inspection.
What to look for in a quote
- Whether the quote is based on a survey or photos
- What records you will receive afterwards
- When the next visit should be, and why
- Whether the work can be done while the site is closed
Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- File each AHU report in the maintenance log
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Questions from Clavering
Do you work at weekends in Clavering?
Yes, evening, overnight and weekend work is normal for us. It means the site in Clavering keeps running as normal. Let us know the hours you are closed and we will book within them.
Do you clean school ventilation in Clavering in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Clavering, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is a quote from photos possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If pictures are not enough, we’ll survey first.
What happens if you cannot reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Do you work in Clavering?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Clavering.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
What affects the cost of AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- Parking and loading at the site
- The condition we find in the survey
- How easy every part is to reach
- Site rules, permits and inductions
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Asking for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- A few general shots of the system
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711, or send details by email.
When something else is needed
In fairness, there are a few things this work won’t fix:
- Building management system faults
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.
