St Stephens questions
Do you cover smaller places like St Stephens?
Yes, St Stephens is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can a school’s ventilation in St Stephens be done out of term time?
Yes, holiday work suits schools best. There are about 10 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of St Stephens. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How long does ventilation cleaning take?
It takes a shift or two for a small system, longer for a whole building. How much ductwork there is and how easily it’s reached decide the rest.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Do you work evenings and weekends?
Yes. We fit the work around when the building is in use. Holidays suit schools, and evenings or weekends suit offices.
What information do you need?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
About our ventilation duct cleaning in St Stephens
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, alongside filter changes and AHU maintenance. The work covers general extract ductwork, grilles and diffusers and supply ductwork, and the jobs we see most are damp or stale smells from grilles and ventilation full of debris from building work.
In a place like St Stephens, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a day or less for a small system and a series of visits for a large one. Visits to a place like St Stephens are planned ahead, so we arrive with what the survey says the job needs.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- After pictures are taken and the certificate and report issued.
Preparing for the visit
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

How the job changes from site to site
Offices and retail
Multi-let buildings may share ductwork between tenants. We plan access with the managing agent.
Hospitals and care homes
In care settings, keeping dust contained is a priority. We protect the work area and take everything away.
Why act early in St Stephens
Where a building in St Stephens serves patients, residents or children, putting off ventilation cleaning is hard to justify. Good indoor air starts with a clean system. It’s easy to lose track of when the work was last done on a quieter site.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Switch the ventilation off or cover grilles during dusty building work
- Keep grilles and diffusers dusted
- Stick to the filter change schedule
- Do not block grilles with furniture or storage
We recommend when the system should next be inspected, based on what we found. Diary it straight away so it isn’t missed.
Protect the system during building work by switching it off or covering the grilles.
Multi-site and managed buildings
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.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
