What affects the quote in Chailey
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The scale of the work
- Whether several sites go on one quote
- How easy every part is to reach
- Whether it’s a one-off visit or part of a schedule
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.
What we need to know
To speed up the quote, send us:
- Your last certificate, test record or report
- Wide photos of the system and the area around it
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
AHU cleaning in Chailey, done properly
We clean air handling units for buildings in Chailey and across East Sussex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers supply and extract fans, dampers and louvres and heating and cooling coils, and the jobs we see most are debris and leaves in the fresh air intake and drain trays holding standing water.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What we do, step by step
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Chailey is set by you, and the travel is our side of the planning.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
How to get a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Signs you need AHU cleaning in Chailey
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Most sites get in touch after spotting one of these:
- Condensate trays that won’t empty
- Plant that has been serviced but not cleaned
- Rooms that smell stuffy when the system runs
- Coils clogged with dust and debris
If you manage a school such as Chailey St Peter's Church of England Primary School, ventilation cleaning is best booked for the holidays.

Your questions about AHU cleaning in Chailey
Can the work in Chailey be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Chailey can fit around your hours. Your opening times are the first thing we ask for.
Can ventilation in schools around Chailey be cleaned out of term?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Chailey, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711 or email us, and we’ll fit the work in.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you cover Chailey?
Yes. Our area takes in London and the counties of South East England, and that includes Chailey.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What happens if it’s left?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A fault that closes a site in a village like Chailey affects everyone who depends on it.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.

From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
