AHU cleaning in Camberley
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. If you have units needing a clean before a new tenant or handover and units that have only ever had filter changes, we can put it right.
In Camberley, ventilation in schools and offices is cleaned when the building is quiet: evenings, weekends or school holidays.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What happens if it’s left?
Stuffy rooms and stale smells in a building in Camberley can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. A fresh certificate on file is the best thing to have when someone asks to see your records.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Camberley: your questions answered
Can you clean school ventilation in Camberley during the holidays?
Yes. The holidays are the usual time for school work. Around Camberley, the Food Standards Agency lists about 22 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work overnight in Camberley?
Yes, we can come after you close and finish before you open. That way a site in Camberley doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What should I send you?
A short description and a few pictures, with the address and opening hours. We’ll ask for anything else we need.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. In Camberley, the visit is planned around your opening hours, parking and access to the system.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
- Dig out any earlier paperwork for the system

When to call us in Camberley
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
If you notice any of these, it’s worth a diagnosis:
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
- Condensate trays that will not empty
- Dust built up on fan impellers
If you manage offices or shops near Camberley station, their ventilation can be inspected and cleaned out of hours.
Questions to ask before booking
- What paperwork you get at the end
- Whether inaccessible sections are listed on the report
- Whether the whole system is included, or only the parts that are easy to reach
- Which accreditations they hold, and whether you can check them
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Camberley buildings and their air
Food Standards Agency records list about 22 schools, colleges and universities, about 16 care, childcare and hospital premises and about 5 hotels and B&Bs registered as food businesses within 1.5 miles or so of the middle of Camberley. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Camberley’s nearest hospital, Frimley Park Hospital, is about 1.2 miles south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. About 30 miles out from central London, Camberley is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
Healthcare buildings such as Frimley Park Hospital, about 1.2 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Camberley, yours matters too. For schools like Prior Heath Infant School, the holidays are the usual time to inspect and clean ventilation.
Camberley is about 9 miles north-west of Guildford, in Surrey.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Fixed quotes for AHU cleaning in Camberley
There’s no set price list, because no two systems are the same. What we look at:
- Parking and loading at the site
- How many systems or sites are involved
- What state the system is in
- How big the system is
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
Asking for a quote
What to send for a quote:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, call us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Watch for drips or damp patches near the plant
- Don’t store bins or materials near the intake
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
