AHU cleaning in Elson, done properly
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you are dealing with plant that needs cleaning after a refit and stale or musty smells from the ventilation, we can put it right.
In a place like Elson, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

The process
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We plan the journey to Elson and bring what the job is likely to need.
- We look at the unit and the plant area during the survey.
- 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.
How to prepare
- Mention any sign-in, permit or induction we need
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
Getting a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, ring 0345 646 2711 or drop us a line.

What a clean will not put right
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It won’t put right:
- Airflow problems caused by the system’s design
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.
Where we work

Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Elson questions
Do you work at weekends in Elson?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can you get to a site in Elson?
Yes. Elson is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
Why deal with it now?
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A quieter site near Elson still needs its system looked after.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Fixed quotes for AHU cleaning in Elson
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Parking and loading at the site
- How big the system is
- Working hours and out-of-hours timing
- Any permits to work or inductions
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
What we need to know
We can often survey from pictures. Try to include:
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
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, you get a fixed price before work begins.

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.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Ventilation in Elson buildings
The FSA’s food hygiene register lists about 26 schools, colleges and universities and about 27 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within 1.5 miles or so of the middle of Elson. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Elson’s nearest hospital, Gosport War Memorial Hospital, is about 1.4 miles south. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Gosport War Memorial Hospital, about 1.4 miles south, is the nearest hospital to Elson, and healthcare sites of every size need their supply air kept clean. For schools like Elson Infant School, the holidays are the usual time to inspect and clean ventilation.
