How we handle AHU cleaning in Hill Green
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for intake sections clogged with outdoor debris and plant that has been serviced but not cleaned, across filter sections, dampers and louvres and drain trays.
In a village or hamlet like Hill Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly before booking.

How we price AHU cleaning
We don’t publish a price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- Whether we need access equipment or extra panels
- The scale of the work
- Where the site is and how we reach it
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
We can often survey from pictures. The most useful are:
- Any previous report or certificate
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or email us.
How the visit works
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Hill Green, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- 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.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Do you need AHU cleaning in Hill Green?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
It’s time to book a visit if you see:
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
- Condensate trays that will not empty
- Dust-coated heating and cooling coils
Hospitals such as Saffron Walden Community Hospital (about 5.5 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Hill Green are no different.

Questions from Hill Green
Can you clean school ventilation in Hill Green during the holidays?
Yes. The holidays are the usual time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hill Green. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
Do you work overnight in Hill Green?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
Is Hill Green in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Hill Green.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
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 a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What’s included in an AHU 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.
Between visits
Good habits slow the build-up between visits. Our tips:
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
- Look at the condensate drain whenever the unit is serviced
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
