Ventilation duct cleaning for kitchens and businesses in Radlett
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, giving the ventilation a clean bill of health on paper. The work covers toilet extract systems, supply ductwork and hospitals and care homes, and common reasons people get in touch are poor airflow from the vents and ventilation that needs a TR19® Air inspection.
Smaller buildings around Radlett often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What affects the quote in Radlett
A fixed price needs a few facts first. We check:
- Any permits to work or inductions
- When the work can happen, such as evenings, overnight or weekends
- What state the system is in
- How big the system is
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
When you contact us, it’s useful to have:
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Radlett buildings and their air
Going by the FSA’s register, there are about 5 schools, colleges and universities and about 3 caring premises (care homes, nurseries and hospitals) serving food within roughly a mile and a half of the centre of Radlett. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Shenley Hospital is the nearest hospital, about 1.4 miles north-east of Radlett. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 16 miles out from central London, Radlett is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
School buildings such as St John's Church of England Infant and Nursery School are normally done in the holidays, so classrooms aren’t disturbed. Healthcare ventilation, from large hospitals like Shenley Hospital (about 1.4 miles north-east) to small clinics, depends on clean filters, coils and ducts. For workplaces around Radlett station with mechanical ventilation, cleaning can be done in the evening or at weekends.

Radlett questions
Do you do school ventilation cleaning in Radlett in the summer holidays?
Yes. The holidays are the usual time for school work. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Radlett. Booking early in the term gives the best choice of holiday dates.
Do you cover smaller places like Radlett?
Yes. Radlett is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Will we have to shut during the visit?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Do you provide a report?
Yes. You get a TR19® certificate and a report with before and after pictures. BESA advises keeping certificates in the maintenance log.
How often do ventilation ducts need cleaning?
There’s no single interval; under TR19® Air, inspection decides. Each report recommends when the system should next be inspected.
Are you insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Do you survey the system first?
Yes. Every job is surveyed first, from photos, drawings or a site visit, then we give you a fixed quote.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- File each ventilation report with the building records
- Include grilles in the cleaning rota
- Diary the next TR19® Air inspection
- Do not run the ventilation while builders are sanding or cutting
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Regular inspection is the core of TR19® Air. Scheduled inspections spot dust before it becomes a major job.
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, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes a shift or two for a small system, longer for a whole building. Getting to the system matters more than parking in a place like Radlett, so let us know how to reach it.
- First we check the layout and any past paperwork.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area
- Arrange a key holder or contact on site
Ask for a quote
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Nearby places to Radlett
What else we do in Radlett
Different parts, different methods
Grilles and diffusers
Where they come out, grilles are taken down and cleaned, then put back.
Extract ductwork
Extract ducts take air out of toilets, washrooms and general areas. Lint, dust and fibres gather inside and slowly narrow.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
