AHU cleaning for kitchens and businesses in St Ibbs
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. Common call-outs are for plant that needs cleaning after a refit and debris and leaves in the fresh air intake, on drain trays, supply and extract fans and heating and cooling coils.
Somewhere as small as St Ibbs, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Fixed quotes for AHU cleaning in St Ibbs
The survey tells us what the work involves. The main factors are:
- A single visit or a regular plan
- How many systems or sites are involved
- The times the site is available
- The condition of the system
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

- Problems your staff have spotted
- Any previous report or certificate
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Do you need AHU cleaning in St Ibbs?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
What we are most often called out for:
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
- Dust built up on fan impellers
- Air handling units with blocked filters
Hospitals such as Lister Hospital (about 2.1 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near St Ibbs are no different.
What to look for in a quote
- Whether the whole system is included, or only the parts that are easy to reach

- Whether a written report and pictures are included

Part by part
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.

The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as St Ibbs, the date and timings are agreed with you well before the day.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Tell us where we can park and unload
- Clear the space around the work
- Let us know when the site is closed or quiet

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, you get a fixed price before any work starts.
Advice
What AHU cleaning cannot fix
Before booking, it helps to know what’s not included:
- Controls and BMS settings that run the unit
- Dirty ducts beyond the unit itself
- Breakdowns that need a mechanical engineer
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly before you book.

Leave it or put it right?
If people in a building in St Ibbs complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Systems in rural buildings are often out of sight and out of mind.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

St Ibbs: your questions answered
Can ventilation in schools around St Ibbs be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 6 schools and colleges with food registrations within roughly a mile and a half of St Ibbs. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you cover smaller places like St Ibbs?
Yes. Villages and rural sites across the South East are part of our work, St Ibbs included. Photos of the system and directions to the site help us plan the visit.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
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, and we can fit those.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
