AHU cleaning in Gaston Green
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. We’re often asked to deal with debris and leaves in the fresh air intake and condensate trays that won’t empty, across internal panels, filter sections and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Every visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
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.

Common questions in Gaston Green
Can a school’s ventilation in Gaston Green be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Gaston Green. You can call us on 0345 646 2711 or drop us a line with the dates the site is empty.
Is Gaston Green within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Do you need to switch the unit off?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Are you insured?
Yes. We’re fully insured, and we can share the details when you need them.
Honest limits
Not every problem is solved by AHU cleaning, and we will tell you before we start. It doesn’t solve:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- Problems with the unit’s controls or sensors
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.
What the work covers
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Drain trays
- Filter sections
- Heating and cooling coils
How we price AHU cleaning
You will get a fixed price before we start. It takes into account:
- The number of sites or systems
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Asking for a quote
What to send for a quote:
- The times we could work without disrupting the site
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
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, you get a fixed price before work begins.
Why it’s worth doing now in Gaston Green
Stuffy rooms and stale smells in a building in Gaston Green can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Rural sites cannot always move to another kitchen or room when something fails.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Why Gaston Green businesses choose us
- Every job surveyed first
- One number for every site across the South East and London

What we’re called out for in Gaston Green
Whatever surrounds a building in Gaston Green, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
These are the problems we see most often:
- Odours coming through the supply air
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
Wherever a school like Spellbrook CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

- Proof of insurance

How it works
A visit follows the same order every time: protect the area, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. The visit itself takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Gaston Green.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Related advice
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Flag stale or damp smells in the supply air
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
- Book the next check in line with the report
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
