AHU cleaning for kitchens and businesses in Great Bromley
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. We are often asked to deal with debris and leaves in the fresh air intake and plant that has been serviced but not cleaned, on internal panels, heating and cooling coils and dampers and louvres.
For a building in or near Great Bromley, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why it’s worth doing now in Great Bromley
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. In a small place like Great Bromley, a system that fails can take a site out of use.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form, and we’ll talk you through it.

For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- The condition of the system
- Where the site is and how we reach it
- The number of sites or systems
- Working hours and out-of-hours timing
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The times we could work without disrupting the site
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Make sure the unit’s access doors open easily
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.

Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Common questions in Great Bromley
Is Great Bromley within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you offer AHU cleaning in Great Bromley?
Yes, we work in Great Bromley and the places around it. Just phone us on 0345 646 2711 or send us an email with a few details of the site.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. If photos are not enough, we will survey first.
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. The shutdown is planned with whoever runs the building.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call us on 0345 646 2711, or email photos and tell us about the site and its opening hours.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. At the end, the area is cleaned down.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. In a small place like Great Bromley, the journey is planned ahead and the visit arranged around the site’s hours.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
Advice
Do you need AHU cleaning in Great Bromley?
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
- Units that have only ever had filter changes
Wherever a school like St George's Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- Whether a survey comes first
- Whether they’re fully insured
- What records you will receive afterwards
- When the next visit should be, and why
