About our AHU cleaning in Great Berry
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you are dealing with air handling units with blocked filters and intake sections clogged with outdoor debris, we can put it right.
Visits to a place like Great Berry are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
Every visit ends with a written report and photos, 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 Great Berry
Do you cover smaller places like Great Berry?
Yes, Great Berry is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Great Berry be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Great Berry can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. Some sites still need a visit, and we will say so.
What we do, step by step
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Getting to the system matters more than parking in a place like Great Berry, so let us know how to reach it.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down

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.

When it’s something else
A few issues sit outside what this work can do:
- Ductwork downstream of the unit, which is a separate clean
- A system that’s undersized for the building
- Coils that are corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711, or send details by email and we’ll say what we think before booking.
Where we work
- Dampers and louvres
- Internal panels
- Drain trays
- Filter sections
- Heating and cooling coils
- Supply and extract fans
Part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Common problems we fix in Great Berry
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Most sites get in touch after spotting one of these:
- Condensate trays that won’t empty
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
If you run an office near Laindon station, its supply ductwork can gather dust for years before anyone looks inside.
Before you book anyone

- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

- Whether they’re fully insured
AHU cleaning in Great Berry: local notes
The FSA’s food hygiene register lists about 4 schools, colleges and universities and about 10 hospitals, care homes and childcare premises with registered kitchens or food service in and around Great Berry, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 22 miles out from central London, Great Berry is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. About 1.9 miles east of Great Berry is Basildon University Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Great Berry, clean ventilation matters as much to you as to a hospital like Basildon University Hospital (about 1.9 miles east). Classrooms and halls at schools such as Great Berry Primary School are easiest to work in when pupils are away.

What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. A planned visit to Great Berry fits your hours; an emergency does not.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.

How we price AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- The number of sites or systems
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- The scale of the work
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711, or send details by email, and we will explain what it covers.
What to send for a quote
We can often survey from pictures. Try to include:
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
To get a fixed quote, give us a ring on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
