What we’re called out for in Thundersley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Common reasons sites call us include:
- Air handling units never cleaned inside
- Leaves and litter drawn into the unit
- Units needing a clean before a new tenant or handover
- Condensate trays that will not empty
If you manage a school such as Thundersley Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- Whether inaccessible sections are listed on the report
- Whether the figure could change on the day
- What hours they’ll be on site
- Whether VAT is included
AHU cleaning for kitchens and businesses in Thundersley
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. Common call-outs are for leaves and litter drawn into the unit and rooms that smell stuffy when the system runs, across supply and extract fans, heating and cooling coils and internal panels.
Around a town like Thundersley, the buildings with ducted ventilation are typically offices, schools, surgeries and care homes. Their supply and extract ducts all gather dust over time, and TR19® Air sets out how to inspect and clean them.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What the work involves, part by part
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.

What affects the cost of AHU cleaning
Sites vary more than people expect. The main factors:
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- The condition we find in the survey
- How easy every part is to reach
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.
What we need to know
To speed up the quote, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- A few general shots of the system
- Any previous report or certificate
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Then give us a ring on 0345 646 2711, or send details by email.
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. With a fire risk assessment or inspection due, getting the work done first puts you on the front foot.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.

Common questions in Thundersley
Can the work in Thundersley be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Thundersley keeps running as normal. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
Do you cover Thundersley for AHU cleaning?
Yes, Thundersley is within the area we cover across London and the South East. To start, ring 0345 646 2711 or drop us a line with a few photos of the system.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
How much does AHU cleaning cost in Thundersley?
It depends on the site, so we quote each one individually. To get one, phone us on 0345 646 2711, or send details by email and tell us about the site and its opening hours.
Which kinds of sites do you work on?
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.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.
How the visit works
Every visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A closed day, an evening or an early start: whichever suits your site in Thundersley, we’ll book around it.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
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 pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Thundersley and across Essex. Larger estates can be phased building by building around the people who use them.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
