Kitchen extraction cleaning in Bull's Green
Looking for kitchen extract cleaning in Bull's Green? We diagnose first, fix the price and book the work around your hours, finishing with a written report and photos.

Different parts, different methods
Canopy and plenum
The plenum is out of sight behind the filters, so it’s easy to forget. We take the filters out and clean the plenum and housing thoroughly.
Restaurant and pub kitchens
Grills, fryers and woks send a lot of fat into the extract, and measured readings show whether the minimum interval is enough.
How we handle kitchen extract cleaning in Bull's Green
We have been trading since 2009, cleaning kitchen extracts across the South East and London. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. The work covers horizontal duct runs, vertical risers and plenums and filters, and the jobs we see most are a TR19 certificate needed for the insurer and heavy grease build-up inside the duct runs. Searching for commercial kitchen extraction cleaning in Bull's Green? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
What can be cleaned depends on what can be reached. Sections without access panels are recorded on the report, and new panels can be fitted so they’re cleaned next time.
In a small place like Bull's Green, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Your questions about kitchen extract cleaning in Bull's Green
Do you work overnight in Bull's Green?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Bull's Green needn’t be disturbed. Your opening times are the first thing we ask for.
Which fire and rescue service is responsible for Bull's Green?
Fire safety enforcement in Bull's Green is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How often does a kitchen extract system need cleaning?
Under BESA guidance, the minimum depends on how long you cook each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings can show a shorter interval is needed.
What do you need from me for a quote?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
Will my insurer ask for a TR19 certificate?
Grease in an extract is a known fire risk, which is why many insurers require TR19 cleaning. Each clean gives you a certificate and photo report to show them.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Common problems we fix in Bull's Green
The type of cooking changes the amount of grease. Frying, grilling and roasting send far more fat into the canopy than steaming or boiling, which is why grease readings matter more than the calendar.
Clients normally contact us when they notice one of these:
- A kitchen with no current TR19 certificate
- Fat running down the canopy edge
- An overdue clean flagged by an EHO or fire officer
- Missing paperwork after a change of operator
Historic houses near Bull's Green, such as Digswell House about 2.6 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Questions to ask before booking
- Whether inaccessible sections are listed on the report
- What’s included in the scope, part by part
- Whether a survey comes first
- Proof of insurance
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What happens if it’s left?
If there’s a fire and the extract hasn’t been cleaned, the paperwork becomes the problem. Many policies require cleaning to TR19, and an insurer can refuse or reduce a claim without proof. A current certificate is far easier to produce than an explanation. Our emergency line runs 24/7, but a planned visit to Bull's Green is calmer for everyone.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

What else we do in Bull's Green
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Your own staff can handle the daily basics: 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.
