AHU cleaning in Shenfield
If the units serving a building in Shenfield have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers drain trays, dampers and louvres and internal panels, and common reasons people get in touch are dirty coils holding back the airflow and units needing a clean before a new tenant or handover.
Around a place like Shenfield, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a place like Shenfield are planned ahead, so we arrive with what the survey says the job needs.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
How to get a quote
We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.

Managing agents and facilities teams in Shenfield
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
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.
What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
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.
Ventilation in Shenfield buildings
Food Standards Agency records list about 14 schools, colleges and universities and about 18 care, childcare and hospital premises registered as food businesses within roughly a mile and a half of the centre of Shenfield. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Shenfield, about 20 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. Shenfield’s nearest hospital, Brentwood Community Hospital, is about 0.5 miles south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
If you manage shops or offices close to Shenfield station, a TR19® Air inspection shows whether the ductwork needs cleaning. Classrooms and halls at schools such as Shenfield St. Mary's Church of England Primary School are easiest to work in when pupils are away. Healthcare ventilation, from large hospitals like Brentwood Community Hospital (about 0.5 miles south) to small clinics, depends on clean filters, coils and ducts.

What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- The scale of the work
- Site requirements such as sign-in and permits
- The times the site is available
- Whether we need access equipment or extra panels
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

What else we do in Shenfield
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
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.
Shenfield questions
Can you get to a site in Shenfield?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you clean school ventilation in Shenfield in the holidays?
Yes, holiday work suits schools best. There are about 14 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Shenfield. Just give us a ring on 0345 646 2711, or email photos with your term dates and we will plan around them.
How long does an AHU clean take?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Can you quote from pictures?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If pictures aren’t enough, we will survey first.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. A quieter site near Shenfield still needs its system looked after.
Whatever the type of site, the quote works 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 explain each part.
