AHU cleaning for kitchens and businesses in Shelley
Our AHU cleaning covers sites in Shelley and the rest of Essex, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers heating and cooling coils, drain trays and filter sections, and common reasons people get in touch are coils clogged with dust and debris and plant that has been serviced but not cleaned.
For a building in or near Shelley, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
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 to a regular schedule.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Report musty smells from the vents right away
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Common questions in Shelley
Can ventilation in schools around Shelley be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Shelley. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Shelley?
Yes. We work evenings, overnight and at weekends. It means the site in Shelley keeps running as normal. Tell us your opening hours when you ask for a quote.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
How long does it take to clean an air handling unit?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Large plant can be split over several shifts, and you can call us on 0345 646 2711 or use the quote form to plan it.

Ventilation in Shelley buildings
There are about 3 schools, colleges and universities and about 4 hospitals, care homes and childcare premises on the FSA’s food hygiene register within about 1.5 miles of central Shelley. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 5.1 miles west of Shelley is St. Margaret's Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. About 21 miles out from central London, Shelley is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
Classrooms and halls at schools such as Ongar Primary School are easiest to work in when pupils are away. Healthcare ventilation, from large hospitals like St. Margaret's Hospital (about 5.1 miles west) to small clinics, depends on clean filters, coils and ducts.

What happens on the day
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in pictures first means the trip to Shelley can be planned properly.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Clear loose items from the work area
- Have your last certificate or report to hand
- Tell us where we can park and unload

Advice
Nearby places to Shelley
Other services in Shelley
What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
What a clean will not put right
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Breakdowns that need a mechanical engineer
- A system that’s undersized for the building
- The supply and extract ducts, quoted separately
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before you book.
