Kitchen extract cleaning in Harwell, Oxfordshire
Our technicians work in Harwell on TR19 Grease cleaning of complete kitchen extract systems, from canopy to discharge. Fixed quotes, work around your opening hours and photo reports as standard.
- Missing paperwork after a change of operator
- An inspection that picked up a dirty extract
- An extract that no longer clears the smoke
When to call us in Harwell
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.
Any of these means the system needs a check-up:
- Years of baked-on grease in the ducts
- An inspection that picked up a dirty extract
- An extract that has never been cleaned to TR19
- Grease dripping from the canopy or filters
Where a hall near Church of St Matthew, or anywhere in Harwell, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Kitchen extract cleaning in Harwell
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 are fully insured, with CHAS, SafeContractor and ISO 9001. The work covers horizontal duct runs, extract fans and canopies and hoods, and people most often call us about an inspection that picked up a dirty extract and an extract that has never been cleaned to TR19. For TR19 kitchen extract cleaning in Harwell, one call covers the survey, the clean and the paperwork.
Before we clean, we look at where the grease is: grease readings at set points tell us where the heaviest deposits are, and readings afterwards go into your report.
In a smaller place like Harwell, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

FAQs for Harwell
Can you work in Harwell outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Harwell doesn’t have to lose a day’s trading. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Which environmental health team covers Harwell?
Kitchens in Harwell are inspected by Vale of White Horse council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Will my insurer ask for a TR19 certificate?
Grease-filled ducts can carry fire well beyond the kitchen. Many insurers require TR19 cleaning, and may refuse or reduce a claim without proof, so keep every certificate.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Is there a survey before the work?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
Do you cover Harwell?
Yes. Harwell is part of the area we cover, as part of our area across London and the South East.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Between visits
Once we’ve finished, these simple steps help:
- Keep the baffle filters clean
- Give the canopy a daily wipe
- Run the extract fan throughout cooking
- Tell us when the extract starts to drip or smell
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.
Regular filter cleaning is the simplest thing a kitchen can do. Clean, well-fitted filters catch more fat before it reaches the duct, which slows build-up further down the system.
Why it’s worth doing now in Harwell
If there’s a fire and the extract hasn’t been cleaned, the paperwork becomes the problem. Many insurers ask for proof of TR19 cleaning and may reduce or refuse a claim without it. A current certificate is far easier to produce than an explanation. In a smaller place like Harwell, a site that has to close is felt quickly.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or send us an email, and we’ll explain what it covers.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Managing agents and facilities teams in Harwell
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Harwell kitchens: local notes
There are about 17 restaurants, cafés and works canteens and about 4 takeaways and sandwich shops in Harwell and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Any of them cooking under a canopy is sending grease into its ductwork every service. In Harwell, food businesses are inspected by environmental health officers from Vale of White Horse council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Harwell is covered by Oxfordshire Fire and Rescue Service. 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.

What affects the quote in Harwell
A fixed price needs a few facts first. We look at:
- A single visit or a regular plan
- Parking and loading at the site
- How many systems or sites are involved
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before work begins.
What we need to know
Before you ask for a quote, gather:
- A few general shots of the system
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
How it works
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 for a small kitchen, longer for a large system. Getting to the system matters more than parking in a place like Harwell, so let us know how to reach it.
- First comes a survey of the whole system, by photos or a visit.
- We measure the grease at set points along the system, then give you a fixed price.
- On the day, cooking equipment is switched off and left to cool, and everything nearby is sheeted.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- We test again, photograph the result and issue your TR19 certificate and photo report.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
How to get a quote
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
