AHU cleaning for kitchens and businesses in Nyetimber
Units vary a lot in size, age and layout, 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. The work covers dampers and louvres, filter sections and drain trays, and the jobs we see most are drain trays holding standing water and intake sections clogged with outdoor debris.
Around a place like Nyetimber, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. Visits to a place like Nyetimber are planned ahead, so we arrive with what the survey says the job needs.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures 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.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
- Let us know about parking and loading

Your questions about AHU cleaning in Nyetimber
Is Nyetimber within the area you cover?
Yes, we work in villages as well as towns, and Nyetimber is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you clean school ventilation in Nyetimber during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Nyetimber. Just call 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
Are you fully insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Can you clean the AHU out of hours?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
Nyetimber buildings and their air
Food Standards Agency records list about 4 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) registered as food businesses within about 1.5 miles of central Nyetimber. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. We cover Nyetimber, about 57 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. About 2.8 miles east of Nyetimber is Bognor Regis War Memorial Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
For schools like Rose Green Infant School, the holidays are the usual time to inspect and clean ventilation.
Nyetimber is about 2 miles south-west of Bognor Regis, in West Sussex. Wherever you are in the PO21 postcode area, we cover AHU cleaning for commercial sites. 371 places in West Sussex are on our list, from busy centres to quieter spots. There’s also a page for Portsmouth, about 15 miles away.
We work across the PO21 postcode area for AHU cleaning and the streets around it. If you need AHU cleaning at premises on Lion Road, Hook Lane and Anson Road or anywhere close by, our technicians can take on the work. If your site is just outside Nyetimber, we cover Pagham (1 mile south-west), Aldwick (1 mile east), South Mundham (2 miles north-west), Fisher (2 miles north-west) and Sidlesham (2 miles west). Larger places within reach include Worthing (15 miles east), Chichester (5 miles north-west), Selsey (4 miles south-west), Littlehampton (9 miles east), Emsworth (10 miles north-west) and Rustington (10 miles east).
Near you in Nyetimber
Locally, jobs take us to businesses close to Avisford, The Regis School and The Lamb pub. The nearest railway station is Bognor Regis station, roughly 2.6 miles east. A little further out are Bognor Regis Museum (2.4 miles east) and Bognor Regis War Memorial Hospital (2.8 miles east).
Honest limits
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.
Where we work
- Drain trays
- Dampers and louvres
- Filter sections
- Internal panels
- Supply and extract fans
- Heating and cooling coils
Signs you need AHU cleaning in Nyetimber
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
Common reasons sites call us include:
- Odours coming through the supply air
- Leaves and litter drawn into the unit
- Condensate trays that won’t empty
- Dust built up on fan impellers
Healthcare ventilation, from large hospitals like Bognor Regis War Memorial Hospital (about 2.8 miles east) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- How they set the interval to the next visit
- Whether the whole system is included, or only the parts that are easy to reach
- What happens if part of the system cannot be accessed
- If the quote is a fixed price or an estimate
Multi-site and managed buildings
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.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Stick to the filter change plan
- Keep the certificate and photo report with the plant records
- Make sure condensate is draining away
- Don’t store bins or materials near the intake
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. A quieter site near Nyetimber still needs its system looked after.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or send us an email, and we’ll talk you through it.

What affects the quote in Nyetimber
We do not publish a price list, because no two systems are the same. The quote depends on:
- Any permits to work or inductions
- Parking and loading at the site
- Whether several sites go on one quote
- The size of the system
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
We can often survey from pictures. Try to include:
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
