Part by part
Grease filters
We clean the grease filters as part of the job, and refitted so they sit properly in the housing. We’ll tell you if any need replacing.
Restaurant and pub kitchens
High-heat cooking loads the extract with grease, so grease readings help set the right interval.
Kitchen extract cleaning in Codicote Bottom
Think of it as a health check for the kitchen’s airways: survey first, clean second, sign-off last. That clean bill of health comes as a TR19 certificate and a photo report, issued through the BESCA Vent Hygiene Elite portal. If you have a new tenancy or takeover with no cleaning history and cleaning needed before an insurance renewal or survey, we can put it right, from extract fans, vertical risers and horizontal duct runs onwards. When a restaurant in Codicote Bottom asks for duct cleaning, it’s nearly always the kitchen extract they mean, and that’s our main job: canopy to fan, to TR19® Grease.
Most kitchens in Codicote Bottom fall into one of BESA’s three bands: every 3 months for 12–16 hours, every 6 months for 6–12 hours and every 12 months for 2–6 hours, adjusted by what the grease readings show.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
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, ready for your insurer.

What kitchen extract cleaning looks like in Codicote Bottom
There are about 4 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Codicote Bottom, according to the Food Standards Agency’s register. Each one that cooks under a canopy has an extract system that collects grease and needs regular cleaning. Hertfordshire Fire and Rescue Service covers Codicote Bottom. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Food hygiene inspections in Codicote Bottom are the job of North Hertfordshire council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Shaw's Corner is about 1.3 miles south-west), access may need planning. Church and community hall kitchens, near Parish Church of St Giles or anywhere around Codicote Bottom, are easy to forget, but their extracts collect grease like any other.

What we’re called out for in Codicote Bottom
How fast grease builds up depends mostly on how long the kitchen cooks each day. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. They are minimums: measured grease levels set the real interval.
Look out for these warning signs:
- Grease smells coming from the extract
- A smoky, hot kitchen with weak extraction
- A kitchen with no current TR19 certificate
- An inspection that picked up a dirty extract
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Codicote Bottom is Queen Elizabeth II Hospital, about 5.2 miles south-east.

What affects the cost of kitchen extract cleaning
The diagnosis comes before the price. We look at:
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Why it’s worth doing now in Codicote Bottom
Putting it off simply moves the grease further down the duct. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Staying on a regular cycle keeps each clean manageable. In a small place like Codicote Bottom, a system that fails can take a site out of use.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What you get with us
- Ventilation hygiene specialists since 2009
- Each visit written up, with photos
- CHAS and SafeContractor accredited, with ISO 9001
- Work around your opening hours, with 24/7 emergency cover

What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes a few hours for a small kitchen, longer for a large system. A few pictures of the system help us make the most of a visit to a place like Codicote Bottom.
- First the diagnosis: a survey of the whole system and its access points.
- Grease readings set the baseline, and a fixed quote follows.
- We arrive after close, protect the area and contain the waste.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
- Find the previous report, if there is one

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
