How we handle kitchen extract cleaning in Farnham Common
Few kitchens can stop cooking for a day so the extract can be cleaned. We work evenings, overnight and at weekends, or between services where the kitchen has a gap. With the equipment off and cool and the area sheeted, we clean and hand the kitchen back ready for the next service. The work covers plenums and filters, canopies and hoods and discharge points, and common reasons people get in touch are an extract that has never been cleaned to TR19 and grease drips onto cooking equipment. Most calls from Farnham Common come after an insurer, an EHO or a fire officer asks to see the last TR19 certificate. We handle the clean and the paperwork in one visit.
BESA sets minimum intervals by hours of cooking a day: 3-monthly for heavy use, 6-monthly for moderate use and yearly for light use, adjusted by what the grease readings show.
In a village or hamlet like Farnham Common, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

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.
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.
What kitchen extract cleaning looks like in Farnham Common
There are about 16 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Farnham Common, according to the Food Standards Agency’s register. Any of them cooking under a canopy is sending grease into its ductwork every service. Farnham Common is covered by Royal Berkshire Fire and Rescue Service. 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 Buckinghamshire council inspect food businesses in Farnham Common. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.
Volunteers running a hall kitchen near St John the Evangelist, or anywhere in Farnham Common, may not know when the extract was last cleaned, and a grease test settles it. If your kitchen is in a listed or historic building, like the houses around Farnham Common (Cliveden is about 3.3 miles west), fitting access panels needs care. For schools such as Farnham Common Junior School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
FAQs for Farnham Common
Which fire authority looks after Farnham Common?
Fire safety enforcement in Farnham Common is handled by Royal Berkshire Fire and Rescue Service. 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.
Do you do school kitchen extract cleaning in Farnham Common in the summer holidays?
Yes. The holidays are the usual time for school work. Around Farnham Common, the Food Standards Agency lists about 7 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
How long does it take to clean a kitchen extract system?
Allow a single shift for most kitchens, with long duct runs and tall risers needing more time. The survey tells us how long your system will need.
How often does a kitchen extract system need cleaning?
BESA guidance gives minimum intervals of 3, 6 or 12 months, depending on daily cooking hours. Heavy frying and grilling can mean shorter intervals, which grease thickness testing will show.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you clean the whole extract system or just the canopy?
All of it, from the canopy through to the discharge. Sections with no access are listed on the report, and extra panels can be fitted.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What affects the cost of kitchen extract cleaning
There’s no set price list, because sites vary so much. What we look at:
- How easy every part is to reach
- A single visit or a regular plan
- The condition of the system
- Site rules, permits and inductions
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before work begins.
What to send for a quote
To help us quote quickly, please include:
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
Getting a quote doesn’t take long. Send a few details and pictures, 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.

Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Honest limits
It’s worth knowing the limits before booking:
- A grease trap that needs emptying
- Extraction that cannot cope with the cooking because of its design
- A fan motor that has burnt out
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
What the work covers
- Horizontal duct runs
- Discharge points
- Canopies and hoods
- Vertical risers
- Plenums and filters
- Extract fans
How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes anything from a few hours to a full night, depending on the size of the system. A quick note on how to find the site and where to park makes a visit to Farnham Common run smoothly.
- First comes a survey of the whole system, by photos or a visit.
- Set points are tested for grease thickness and the quote is fixed before any work starts.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- Canopy, plenum, filters, duct runs, risers, fan and discharge are all cleaned to TR19® Grease.
- We test again, photograph the result and issue your TR19 certificate and photo report.
Before we arrive
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
Ask for a quote
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

Why it’s worth doing now in Farnham Common
An overdue clean in Farnham Common is best dealt with now rather than after the next inspection. The job takes a few hours for a small kitchen, longer for a large system, and we fit around your opening hours. Waiting only adds grease and risk. It’s worth booking a check, because nobody sees inside a duct day to day.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
