About our kitchen extract cleaning in Langley End
Duct Doctor has been cleaning kitchen extract systems since 2009. 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. If you have cleaning needed before an insurance renewal or survey and a system with no record of a TR19 clean, we can help, from vertical risers, extract fans and discharge points onwards. For TR19 kitchen extract cleaning in Langley End, one call covers the survey, the clean and the paperwork.
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.
Work in a small place like Langley End 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Keep the TR19 certificate and photo report in the maintenance log
- Never cook with filters missing or out of place
- Run the extract fan throughout cooking
- Give the canopy a daily wipe
The kitchen is left clean and ready for the next service. Grease and dirty water are collected and taken off site, and equipment can be switched back on once we’ve gone.
Tell whoever looks after the system when something changes. Grease dripping from the canopy, a burning smell or a fan that sounds rough are all signs of build-up, and a grease thickness test can confirm it.
When something else is needed
It’s worth knowing the limits before booking:
- A damper that sticks or has a damaged link
- Fat blocking the kitchen drains
- Damaged duct sections that need replacing
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.

What kitchen extract cleaning looks like in Langley End
The FSA’s food hygiene register includes about 3 pubs and bars within roughly a mile and a half of the centre of Langley End. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Hertfordshire Fire and Rescue Service covers Langley End. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Environmental health officers from North Hertfordshire council inspect food businesses in Langley End. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
A hall kitchen that only cooks for events, whether near All Saints Church or elsewhere in Langley End, still needs its extract cleaned, just less often. Healthcare kitchens, like those at hospitals such as Lister Hospital (about 2.6 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

The process
Every visit runs to the same pattern: protect the area, make the system safe, carry out the kitchen extract cleaning, tidy up and leave you the report. On site, the work takes a few hours for a small kitchen, longer for a large system. Photos of the system and how to reach it help us plan a visit to Langley End.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Getting ready for the visit
- Find the previous report, if there is one
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.

Langley End questions
Who carries out food hygiene inspections in Langley End?
The local authority for Langley End is North Hertfordshire council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire and rescue service is responsible for Langley End?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Langley End. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What does a TR19 kitchen extract clean include?
All of it, from the canopy through to the discharge. Where there are not enough access panels to reach a section, it’s recorded, and we can fit new ones.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Are you a BESCA Vent Hygiene Elite member?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Common problems we fix in Langley End
What’s on the menu matters as much as how much is cooked. Frying, grilling and roasting send far more fat into the canopy than steaming or boiling, so two kitchens with the same hours can need very different intervals.
Signs it’s time to call us include:
- Cleaning needed before an insurance renewal or survey
- A kitchen taken over without any extract records
- A system with no record of a TR19 clean
- Years of baked-on grease in the ducts
If your kitchen is in a listed or historic building, like the houses around Langley End (Knebworth House is about 2.7 miles south-east), fitting access panels needs care.

- Whether VAT is included
- Whether the price is fixed
- What happens if part of the system cannot be accessed
What affects the quote in Langley End
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- The size of the system
- Where the site is and how we reach it
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
Before you ask for a quote, gather:
- Wide photos of the system and the area around it
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
For a fixed quote, call us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.
How the job changes from site to site
Ductwork and risers
Bends and changes of direction trap more grease than straight runs. We test at points like these before and after cleaning, so the report shows the difference.
Schools, hospitals and care homes
Institutional kitchens tend to cook to set hours, so cleans can be planned for holidays or quiet times. The certificate goes straight into the site’s maintenance records.
Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
