How we handle AHU cleaning in Filching
Our AHU cleaning covers sites in Filching and the rest of East Sussex, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have debris and leaves in the fresh air intake and plant that has been serviced but not cleaned, we can help, from drain trays, dampers and louvres and heating and cooling coils onwards.
In a village or hamlet like Filching, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

AHU cleaning around Filching
Going by the FSA’s register, there are about 10 hospitals, care homes and childcare premises serving food in Filching and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Filching, about 50 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Filching’s nearest hospital, Eastbourne District General Hospital, is about 2.3 miles south-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
For schools like Willingdon Primary School, the holidays are the usual time to inspect and clean ventilation.
Filching is about 3 miles north-west of Eastbourne, in East Sussex. Filching gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. We cover 289 places across East Sussex, from busy centres to quieter spots. Brighton is in our area too, around 16 miles away.
Our technicians cover all of the BN26 postcode area for AHU cleaning and the streets around it. We also cover Wannock (1 mile north-east), Folkington (1 mile north-west), Lower Willingdon (1 mile east), Willingdon (1 mile east) and Polegate (2 miles north-east). Larger places within reach include Eastbourne (3 miles south-east), Hastings (15 miles east), Bexhill-on-Sea (11 miles east), Seaford (5 miles west), Lewes (11 miles north-west) and Hailsham (4 miles north).

The nearest railway station is Polegate station, roughly 1.5 miles north-east of the centre. A little further out are Burlough Castle (2.5 miles west) and Eastbourne District General Hospital (2.3 miles south-east). For a walk, there’s Combe Hill.
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Filching, the date and timings are agreed with you well before the day.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Filching simpler. With notice, the visit to Filching can be fitted around your bookings and events.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

When to call us in Filching
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Any of these means the system needs a check-up:
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Units that have only ever had filter changes
- Drain trays holding standing water
Healthcare buildings such as Eastbourne District General Hospital, about 2.3 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Filching, yours matters too.
Questions to ask before you book
- How they set the interval to the next visit
- If the quote is a fixed price or an estimate
- Proof of insurance
- Whether the whole system is included, or only the parts that are easy to reach
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
We also work for facilities teams across offices, schools and healthcare in Filching and across East Sussex. Larger estates can be phased building by building to keep disruption down.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
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 the price is fixed before work begins.
What to send for a quote
We can often survey from pictures. The most useful are:
- Any previous report or certificate
- Wide pictures of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You’ll usually have a quote within one working day.
Common questions in Filching
Can you come to Filching after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Filching keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Is Filching within the area you cover?
Yes. Filching is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
What if parts of the system can’t be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Which parts of an air handling unit do you 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.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Honest limits
Before you book, it helps to know what’s not included:
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think.
