When to call us in Nyton
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Common reasons sites call us include:
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Plant that has been serviced but not cleaned
- Dirty fans and fan housings
For schools like Ormiston Six Villages Academy, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book

About our AHU cleaning in Nyton
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. We are often asked to deal with plant that has been serviced but not cleaned and air handling units due a clean after building work, across drain trays, supply and extract fans and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Every visit ends with a written report and pictures, 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.

FAQs for Nyton
Do you do school ventilation cleaning in Nyton in the summer holidays?
Yes. The holidays are the usual time for school work. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Nyton, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work overnight in Nyton?
Yes, nights and weekends are routine for us. That way a site in Nyton doesn’t have to lose a day’s trading. Let us know the hours you are closed and we will book within them.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What else we do in Nyton
How the job changes from site to site
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Ventilation in Nyton buildings
Food Standards Agency records list about 7 schools, colleges and universities and about 10 caring premises (care homes, nurseries and hospitals) registered as food businesses in Nyton and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. Bognor Regis War Memorial Hospital is the nearest hospital, about 3.4 miles south of Nyton. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. At about 52 miles from central London, Nyton sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
Healthcare ventilation, from large hospitals like Bognor Regis War Memorial Hospital (about 3.4 miles south) to small clinics, depends on clean filters, coils and ducts.

For landlords and multi-site operators
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What a clean won’t put right
A few issues sit outside what this work can do:
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
If you are not sure, just ring 0345 646 2711 or use the quote form and we’ll give you a straight answer.

What affects the quote in Nyton
Every site gets its own quote. These are the things that affect it:
- Access, including roofs, risers and ceiling voids
- Any permits to work or inductions
- A single visit or a regular plan
- The condition we find in the survey
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- A few general shots of the system
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A few pictures of the system help us make the most of a visit to a place like Nyton.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- 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
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.
