Commercial kitchen extraction cleaning in Todd's Green
We have been trading since 2009, cleaning kitchen extracts across the South East and London. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. Common call-outs are for a smoky, hot kitchen with weak extraction and an inspection that picked up a dirty extract, across discharge points, horizontal duct runs and canopies and hoods. Searching for commercial kitchen extraction cleaning in Todd's Green? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
Most kitchens in Todd's Green fall into one of BESA’s three bands: 3-monthly for heavy use, 6-monthly for moderate use and yearly for light use, adjusted by what the grease readings show.
For a kitchen in or near Todd's Green, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The paperwork matters as much as the work. You get a written report with pictures after every visit, 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.

How we price kitchen extract cleaning
Before we fix a price, we need to know a few things. We look at:
- Where the site is and how we reach it
- Site rules, permits and inductions
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
What to send for a quote
What to send for a quote:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- Wide pictures of the system and the area around it
- Where the site is and what kind of site it is
Getting a quote doesn’t take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
When something else is needed
Not every problem is solved by kitchen extract cleaning, and we’d rather say so up front. It won’t put right:
- Fire dampers that won’t close (that needs damper testing and remedials)
- Blocked drains from a neglected grease trap (a separate service)
- Damaged duct sections that need replacing
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly before booking.
Parts of the system we cover
- Discharge points
- Vertical risers
- Canopies and hoods
- Extract fans
- Horizontal duct runs
- Plenums and filters
Why act early in Todd's Green
Leaving the clean until the next refit doesn’t make the grease go away. Over time, soft grease bakes into a harder, thicker crust, which is slower to clean. Staying on a regular cycle keeps each clean manageable. Planning a trip to Todd's Green ahead is easier for everyone than a rushed one.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Why book with us
- CHAS, SafeContractor and ISO 9001
- Work around your opening hours, with 24/7 emergency cover
- A fixed price before any work starts
- One number for every site across the South East and London

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. 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. Reaching it takes a specialist with the right equipment.
The process
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes anything from a few hours to a full night, depending on the size of the system. Somewhere as small as Todd's Green, the date and timings are agreed with you well before the day.
- We survey the system first, from your photos and details or on a site visit.
- Set points are tested for grease thickness and the quote is fixed before we start.
- With the kitchen closed and equipment off and cool, the area is sheeted.
- The whole route is cleaned, from the canopy through the ductwork to the fan and the discharge.
- We test again, photograph the result and issue your TR19 certificate and photo report.
Getting ready for the visit
- Let us know about parking and loading
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

It takes anything from a few hours to a full night, depending on the size of the system. We’ll confirm the time when we quote.
Common problems we fix in Todd's Green
Hours of cooking are the biggest factor. BESA guidance sets minimum cleaning intervals of every 3 months for 12 to 16 hours a day, 6 months for 6 to 12 hours, and 12 months for 2 to 6 hours. They are minimums: measured grease levels set the real interval.
Most sites get in touch when they notice something like this:
- Grease drips onto cooking equipment
- An extract that has never been cleaned to TR19
- Grease smells coming from the extract
- A smoky, hot kitchen with weak extraction
Healthcare kitchens, like those at hospitals such as Lister Hospital (about 0.6 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.
