Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
AHU cleaning in East Preston, done properly
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers internal panels, drain trays and supply and extract fans, and people most often call us about units that have only ever had filter changes and dust built up on fan impellers.
In a place like East Preston, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
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. The inside of ducts and units needs a specialist.
Common questions in East Preston
Can you clean school ventilation in East Preston during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of East Preston. You can phone us on 0345 646 2711 or send us an email with the dates the site is empty.
Can the work in East Preston be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in East Preston keeps running as normal. Your opening times are the first thing we ask for.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained to keep the area clean.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
AHU cleaning in East Preston: local notes
Food Standards Agency records list about 18 schools, colleges and universities and about 19 care, childcare and hospital premises registered as food businesses in East Preston and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. East Preston, about 50 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. Zachary Merton Hospital is the nearest hospital, about 1 mile west of East Preston. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
School buildings such as East Preston Infant School are normally done in the holidays, so classrooms are not disturbed. If you manage shops or offices close to Angmering station, a TR19® Air inspection shows whether the ductwork needs cleaning. Hospitals such as Zachary Merton Hospital (about 1 mile west) show how much a building can rely on clean ventilation, and smaller healthcare sites near East Preston are no different.

The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. In a smaller place like East Preston, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Mention any sign-in, permit or induction we need

Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Stick to the filter change plan
- Book the next check in line with the report
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What affects the quote in East Preston
The price is fixed before any work begins. It’s based on:
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. Just send:
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- Problems your staff have spotted
- Where the site is and what kind of site it is
If you need AHU cleaning in East Preston, call 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote normally follows within one working day.
Honest limits
It’s worth knowing the limits before booking:
- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think.
What we work on in East Preston
- Dampers and louvres
- Drain trays
- Internal panels
- Filter sections
- Supply and extract fans
- Heating and cooling coils
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. 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. In a smaller place like East Preston, a site that has to close is felt quickly.
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.
