Codicote extract fan cleaning
Extract fan cleaning for Codicote and the surrounding area: a survey, a fixed price, careful work and proper paperwork. Call for a fixed quote.
- A fan coated in grease inside its housing
- A fan that hums, whines or rumbles
- Burning smells from the fan area
Keeping the system healthy
To keep the system working properly between visits:
- Tell us if the extract feels weaker
- Check the report shows the fan was cleaned
- Never cook with a filter missing
- Listen for new noises or vibration from the fan
The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Extract fan cleaning in Codicote, done properly
Not all extract fans are the same: fans on the roof, fans built into the duct run, and fans on an outside wall. The way in depends on the type, and we plan that during the survey. Typical jobs include a heavily greased fan housing and grease around the motor and its mounts, across centrifugal fans, discharge points and fan housings.
Kitchens around a place like Codicote are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of extract fan cleaning
There’s no set price list, because sites vary so much. What we look at:
- A single visit or a regular plan
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
- Access, including roofs, risers and ceiling voids
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- When the site is open and when it’s quiet
- Your last certificate, test record or report
- Any access panels or hatches you can see
- The postcode and the type of business
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 so you know the cost before any work starts.
Codicote kitchens: local notes
Look up Codicote on the FSA’s food hygiene register and you’ll find about 4 cafés, restaurants and staff canteens in and around Codicote, up to about a mile and a half out. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. It’s North Hertfordshire council that sends environmental health officers to food businesses in Codicote. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Codicote sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Volunteers running a hall kitchen near Parish Church of St Giles, or anywhere in Codicote, may not know when the extract was last cleaned, and a grease test settles it. Historic houses near Codicote, such as Shaw's Corner about 1.7 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Codicote is about 4 miles north-west of Welwyn Garden City, in Hertfordshire. Every kind of commercial site in Codicote, we can take on extract fan cleaning.

Landmarks near Codicote
In Codicote, that means kitchens and buildings near The Goat Public House, Monk's Walk School and Danesbury Park and the streets around them.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Signs you need extract fan cleaning in Codicote
A fan in Codicote builds up grease at a rate set by the kitchen, not the location: daily hours and the amount of frying and grilling. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
These are the problems we see most often:
- A fan left out of previous cleans
- A smell of hot grease from the extract
- Grease around the motor and its mounts
- Grease escaping from the fan outlet
Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 5 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a few hours where there are several fans or heavy deposits. A site near Codicote typically has room to park, so the questions are about access to the system and your hours.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it cannot run while we work.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Preparing for the visit
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet

Why act early in Codicote
A fan that fails mid-service can stop a kitchen cooking. Many fan problems start with grease, so keeping it clean is part of keeping it running. We also offer a 24/7 emergency callout if the worst happens. Systems on quieter sites still build up dirt and wear, just more slowly.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
