What the work involves, part by part
Grilles and diffusers
Grilles and diffusers are where the ducts meet the room. They’re cleaned along with the ductwork, so the room side matches the duct side.
Schools and colleges
Schools and colleges are easiest to clean during the holidays, with nobody in the classrooms.
Ventilation duct cleaning for kitchens and businesses in Woollensbrook
When the work is finished, you get a TR19® certificate and before and after pictures. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. Common call-outs are for extract ducts clogged with lint and dust and ventilation that needs a TR19® Air inspection, on grilles and diffusers, hospitals and care homes and offices and schools.
Somewhere as small as Woollensbrook, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Landlords, agents and facilities managers
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
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.
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
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, alongside our reports.
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes a day or less for a small system and a series of visits for a large one. A few pictures of the system help us make the most of a visit to a place like Woollensbrook.
- We survey the system from drawings, photos or a site visit.
- We inspect inside the ductwork at set points and photograph it.
- We protect the rooms beneath and switch the system off.
- Dust and debris are removed from ducts, grilles and diffusers.
- We issue a TR19® certificate and a photo report listing what was cleaned.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand

Advice
Between visits
Good habits slow the build-up between visits. Our tips:
- Flag any dust coming out of the vents
- Watch for water stains around grilles
- Switch the ventilation off or cover grilles during dusty building work
- Include grilles in the cleaning rota
What was cleaned is listed, along with any parts that weren’t accessible, with pictures before and after. We’ll suggest where new access panels would help.
Make sure there are enough access panels to inspect and clean the ducts. Hidden sections are the ones that get worst.

Leave it or put it right?
Smells, dust around grilles and stuffy rooms are signs the system needs attention. Dealing with them now stops them getting worse. In a small place like Woollensbrook, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Do you need ventilation duct cleaning in Woollensbrook?
Moisture in ducts makes dust stick. Where there’s condensation or a leak, dust clings and builds faster, and it becomes harder to remove.
The symptoms we’re asked about most are:
- Dusty supply ductwork that hasn’t been cleaned in years
- Ventilation full of debris from building work
- Rooms that feel airless when the system runs
- Blocked general extract ductwork
Hertford County Hospital, about 3.1 miles north-west, is the nearest hospital to Woollensbrook, and healthcare sites of every size need their supply air kept clean.

Woollensbrook questions
Can you clean school ventilation in Woollensbrook during the holidays?
Yes, and it’s the easiest time to do it. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Woollensbrook. You can give us a ring on 0345 646 2711, or email photos with the dates the site is empty.

Yes, out-of-hours work is a big part of what we do. The work in Woollensbrook can fit around your hours. When you ring 0345 646 2711 or email us, mention when the site is quiet.
What if there are not enough access panels?
Accessible sections are cleaned and the others recorded. Extra access panels can solve it, and we can quote for them.
Is TR19 a legal requirement?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
How often do ventilation ducts need cleaning?
TR19® Air is risk-based, so cleaning follows inspection rather than a fixed calendar. We suggest a next inspection date after every visit.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call us on 0345 646 2711, or email photos.
