AHU cleaning in The Warren
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with units that have only ever had filter changes and filters that are clogged or overdue, on filter sections, heating and cooling coils and drain trays.
Visits to a place like The Warren are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Questions from The Warren
Do you do school ventilation cleaning in The Warren in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of The Warren. Just give us a ring on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Will you come out to The Warren?
Yes. Villages and rural sites across the South East are part of our work, The Warren included. Just mention lanes, gates or anything else about the site when you book.
How much does AHU cleaning cost in The Warren?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or email us with the site type, opening hours and a few photos.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
The Warren buildings and their air
Food Standards Agency data includes about 8 schools, colleges and universities and about 7 caring premises (care homes, nurseries and hospitals) in The Warren and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 28 miles out from central London, The Warren is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Heatherwood Hospital is the nearest hospital, about 1.6 miles east of The Warren. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Heatherwood Hospital, about 1.6 miles east, is the nearest hospital to The Warren, and healthcare sites of every size need their supply air kept clean. For schools like Harmans Water Primary School, the holidays are the usual time to inspect and clean ventilation. If you run an office near Martins Heron station, its supply ductwork can gather dust for years before anyone looks inside.

Landmarks near The Warren
Typical jobs here are in premises near LVS Ascot and Ranelagh School and the streets around them. There’s a railway station in The Warren itself: Martins Heron station. A little further out are Heatherwood Hospital (1.6 miles east) and The Lexicon (1.5 miles north-west). Not far away are Heath Lake and Wildmoor Heath.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- How easy every part is to reach
- Where the site is and how we reach it
- The condition of the system
- Site rules, permits and inductions
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
Helping us quote
To speed up the quote, please include:
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
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, the quote is fixed before any work is booked.
Between visits
Here’s the after-treatment advice, short and simple:
- Change filters on schedule and log each change
- Don’t store bins or materials near the intake
- Check the drain tray is emptying during routine visits
- Store the TR19 paperwork where auditors can find it
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Why act early in The Warren
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Booking now means the visit to The Warren is planned around you, not forced by a breakdown.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Around The Warren, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Preparing for the visit
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
