AHU cleaning in Birling Gap, done properly
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. If you have dust built up on fan impellers and units needing a clean before a new tenant or handover, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Somewhere like Birling Gap, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
How to get a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

When to call us in Birling Gap
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
The symptoms we are asked about most include:
- Leaves and litter drawn into the unit
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
Hospitals such as Eastbourne District General Hospital (about 4.1 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Birling Gap are no different.
What your quote should include
- If they look at the system before pricing
- Whether the work can be done while the site is closed
- Whether a written report and photos are included
- Whether they recommend a next date

Different parts, different methods
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.

Birling Gap: your questions answered
Can you get to a site in Birling Gap?
Yes, Birling Gap is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you offer AHU cleaning in Birling Gap?

Are you insured?

What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Can you clean without disrupting the building?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. 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. It’s simpler to plan the work at Birling Gap now than to arrange it in a hurry later.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

Aftercare tips
How long the results last depends on use and care. We suggest:
- Check the drain tray is emptying during routine visits
- Report musty smells from the vents right away
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
