About our AHU cleaning in Lindford
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. Every job starts with a survey, from photos or on site, followed by a fixed quote, so you know where you stand. We’re often asked to deal with intake sections clogged with outdoor debris and coils clogged with dust and debris, across heating and cooling coils, dampers and louvres and drain trays.
Smaller buildings around Lindford often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

The process
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Evenings, weekends or a closed day all work for a site in a place like Lindford.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
Ask for a quote
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or use the quote form.
Related advice
What we are called out for in Lindford
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Any of these means the system needs a check-up:
- Drain trays holding standing water
- Leaves and litter drawn into the unit
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
If you manage a school such as Weyford Nursery and Primary School, ventilation cleaning is best booked for the holidays.

What affects the quote in Lindford
We quote each job individually. This is what makes a difference:
- One-off work versus a regular cycle
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- How big the system is
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels

Yes, nights and weekends are routine for us. Your customers, staff or residents in Lindford needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.

Yes. Villages and rural sites across the South East are part of our work, Lindford included. Let us know about access, parking and anything unusual about getting there when you book.
How much does AHU cleaning cost in Lindford?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
What’s TR19?
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.
Is a quote from pictures possible?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If photos aren’t enough, we will survey first.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Between visits
Simple habits between visits make a real difference. We recommend:
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
