How we handle kitchen extract cleaning in Denchworth
Any kitchen we clean in Denchworth gets exactly the same specification as everywhere else we work. The job starts with a survey and grease readings, then works through canopy, plenum, filters, ductwork, fan and discharge. At the finish there’s a TR19 certificate and a before and after photo report. We’re often asked to deal with ductwork thick with old, hardened grease and cleaning needed before an insurance renewal or survey, on vertical risers, horizontal duct runs and extract fans. Hood cleaning is where most enquiries from Denchworth start: a clean that goes past the canopy into the duct and fan, backed by a certificate.
A kitchen running fryers and chargrills all day builds up grease much faster than one that mostly steams and boils, so the interval is set by what you cook as well as how long.
Work in a small place like Denchworth 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.
We have been trading since 2009, as 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.

What affects the cost of kitchen extract cleaning
Your quote is based on your site. We consider:
- Travel, parking and unloading
- The condition of the system
- Any permits to work or inductions
- The number of sites or systems
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
Asking for a quote
To speed up the quote, please include:
- A few general shots of the system
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To help us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then call 0345 646 2711 or email us.
What we’re called out for in Denchworth
The type of cooking changes the amount of grease. Fryers, grills and open flames throw much more fat into the extract than gentler cooking, which is why grease readings matter more than the calendar.
Look out for any of the following:
- Fat running down the canopy edge
- Proof of cleaning requested by an insurer
- An inspection that picked up a dirty extract
- Stale cooking odours from the system
If you run catering at a historic house or estate in the area (Longworth House is about 4.7 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
Before booking anyone
- Whether the price is fixed
- What insurance they carry
- What paperwork you get at the end
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Kitchen extract cleaning in Denchworth: the local picture
Look up Denchworth on the FSA’s food hygiene register and you will find about 3 restaurants, cafés and works canteens and about 3 sandwich bars and takeaways within roughly a mile and a half of the centre of Denchworth. Any of them cooking under a canopy is sending grease into its ductwork every service. Food hygiene inspections in Denchworth are the job of Vale of White Horse council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Oxfordshire Fire and Rescue Service covers Denchworth. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Volunteers running a hall kitchen near Church of St James, or anywhere in Denchworth, may not know when the extract was last cleaned, and a grease test settles it.
Denchworth is about 3 miles north-west of Wantage, in Oxfordshire. Wherever you are in the OX12 postcode area, we cover kitchen extract cleaning for commercial sites. 443 places in Oxfordshire are on our list, from busy centres to quieter spots. Oxford is in our area too, around 13 miles away.

Why deal with it now?
After a fire, one of the first questions is often when the extract was last cleaned. Many insurers ask for proof of TR19 cleaning and may reduce or refuse a claim without it. A certificate in the file answers that question. A planned visit to Denchworth is easier to arrange than an emergency callout.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

What kitchen extract cleaning cannot fix
Some problems need a different service or another trade:
- Damaged duct sections that need replacing
- Fire dampers that will not close (that needs damper testing and remedials)
- Extraction that can’t cope with the cooking because of its design
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.

How it works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes as long as the system needs, from a few hours to several planned visits. In a small place like Denchworth, the journey is planned ahead and the visit arranged around the site’s hours.
- First the diagnosis: a survey of the whole system and its access points.
- 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.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
How to get a quote
Quotes are quick. 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.

Common questions in Denchworth
Can you clean school kitchen extracts in Denchworth during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Denchworth. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Can you get to a site in Denchworth?
Yes, Denchworth is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
What’s the right cleaning interval for a kitchen extract?
It depends on how many hours a day the kitchen cooks. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. Your report gives a recommended next clean date.
Will I get a certificate after the clean?
A TR19 certificate, plus a full photo report. The report lists what was cleaned, anything we couldn’t reach and when the next clean is due.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you clean the whole extract system or just the canopy?
A TR19 Grease clean covers the full extract route, not just the canopy. That means canopy, plenum, filters, ducts, risers, fan and discharge, reached through access panels where necessary.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Empty any grease troughs or cups on the canopy
- Never cook with filters missing or out of place
- Clean the grease filters regularly between TR19 cleans
- Flag any change in how the extract sounds or works
The certificate records when the clean was done, where and by whom. Keep it in the maintenance log with your fire risk assessment so it’s ready when anyone asks to see it.
Stick to the cleaning interval on the certificate. BESA guidance links the minimum interval to daily cooking hours, so a change in hours may mean a change in interval, and grease readings will show it.
What the work involves, part by part
Canopy and plenum
Grease meets the system first at the canopy and the plenum behind the filters. We clean both inside and out, with the filter housing cleaned too.
Extract fan and discharge
Attenuators, where fitted, can soak up grease and need attention. We clean what can be reached and note anything that cannot.
