AHU cleaning for kitchens and businesses in Hastingwood
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, which is why we clean the unit itself, not just the ducts. Typical jobs include dust built up on fan impellers and odours coming through the supply air, across heating and cooling coils, internal panels and supply and extract fans.
For a building in or near Hastingwood, access is agreed in advance and the visit is planned around the journey.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Aftercare tips
So the system stays in good health:
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
What a clean won’t put right
Before you book, it helps to know what’s not included:
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think.

AHU cleaning in Hastingwood: local notes
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 6 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Hastingwood. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 3.2 miles north-west of Hastingwood is Princess Alexandra Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. About 20 miles out from central London, Hastingwood is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
Healthcare buildings such as Princess Alexandra Hospital, about 3.2 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Hastingwood, yours matters too. School buildings such as Henry Moore Primary School are usually done in the holidays, so classrooms are not disturbed.

What affects the quote in Hastingwood
We do not publish a price list, because no two systems are the same. What we look at:
- Travel, parking and unloading
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- The condition of the system
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Hastingwood.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Let us know about parking and loading
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
Getting a quote
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

How the job changes from site to site
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Leave it or put it right?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Somewhere as small as Hastingwood, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Hastingwood questions
Can you clean school ventilation in Hastingwood during the holidays?
Yes, out-of-term visits are normal for schools. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Hastingwood, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you cover smaller places like Hastingwood?
Yes. Villages and rural sites across the South East are part of our work, Hastingwood included. Photos of the system and directions to the site help us plan the visit.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How long does an AHU clean take?
The work 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, so call 0345 646 2711 or send us an email to talk it through.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
