Extract fan cleaning in Todd's Green
Duct Doctor has been cleaning kitchen extract fans since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you have thick grease on the impeller and casing and a motor area thick with grease, we can help.
Work in a small place like Todd's Green starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Good records are part of the job. Each visit is written up with pictures, 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.

FAQs for Todd's Green
Can school kitchens in Todd's Green be cleaned in the holidays?
Yes. The holidays are the usual time for school work. Around Todd's Green, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. Just call 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Can you work in Todd's Green outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you call 0345 646 2711, or email photos, mention when the site is quiet.
Do you need to turn the fan off to clean it?
The fan is isolated before we open it, so it can’t run during the clean. That means the extract is off, so we clean while the kitchen is closed.
What do you need from me for a quote?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call us on 0345 646 2711 or use the quote form.
Is TR19 a legal requirement?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What if the fan needs more than a clean?
Anything beyond cleaning is flagged, with what we found. We offer extract fan repair and replacement, and there’s a 24/7 emergency callout for breakdowns.
Is the fan included in a TR19 clean?
Yes, a full TR19 clean includes the fan. Anything that can’t be reached is recorded, so you always know what was cleaned.
What your team can do, and what needs us
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.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What extract fan cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning will not do:
- Damaged fan blades
- A fan that was never right for the kitchen
- A faulty speed controller or isolator
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think.
Parts of the system we cover
- Centrifugal fans
- In-line fans
- Fan housings
- Axial fans
- Roof-mounted fans
- Discharge points
What extract fan cleaning looks like in Todd's Green
The FSA’s food hygiene register includes about 23 pubs and bars and about 3 hotels and B&Bs within roughly a mile and a half of the centre of Todd's Green. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Environmental health officers from Stevenage council inspect food businesses in Todd's Green. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Todd's Green falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run catering at a historic house or estate in the area (Knebworth House is about 3.5 miles south), event kitchens in older buildings often have awkward duct runs that need planning. If you look after a school kitchen, at a school such as The John Henry Newman School or anywhere near Todd's Green, the holidays are the usual time for a TR19® clean.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Look for grease stains near the discharge
- Report rattles or humming early
- Leave a clear route to the fan
- Tell us if the extract feels weaker
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
A change in how the fan sounds is worth noting. New noise or vibration often means grease is building on the impeller, and catching it early keeps it a cleaning job.
When to call us in Todd's Green
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.
Keep an eye out for these warning signs:
- A fan that no longer moves enough air
- A fan left out of previous cleans
- A fan that hums, whines or rumbles
- A fan shaking on its mounts
If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in Todd's Green, its extract still collects grease from every lunch and event.
