How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- A single visit or a regular plan
- The condition of the system
- Parking and loading at the site
- Working hours and out-of-hours timing
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What to send for a quote
To speed up the quote, please include:
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before we start.
AHU cleaning for kitchens and businesses in Bicknacre
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for odours coming through the supply air and dust built up on fan impellers, on dampers and louvres, internal panels and heating and cooling coils.
For a building in or near Bicknacre, access is agreed in advance and the visit is planned around the journey.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Bicknacre: your questions answered
Do you do school ventilation cleaning in Bicknacre in the summer holidays?
Yes, holiday work suits schools best. Around Bicknacre, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Just call us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Can you work in Bicknacre outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Bicknacre keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
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.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.

Common problems we fix in Bicknacre
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Units that have only ever had filter changes
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
Healthcare ventilation, from large hospitals like Baddow Hospital (about 3.6 miles west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- How areas they can’t reach will be recorded
- Exactly which parts of the system are covered
- If the quote is a fixed price or an estimate
- Whether the quote is based on a survey or photos
Why deal with it now?
If people in a building in Bicknacre complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will go through it with you.
Why book with us
- Fixed quotes from a survey or photos
- Trading since 2009
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fully insured

What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Bicknacre and turn up when the site is quiet.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- 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
- Find the previous report, if there is one
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
