How we price canopy cleaning
A fixed price needs a few facts first. We check:
- Site requirements such as sign-in and permits
- The size of the system
- The times the site is available
- The condition we find in the survey
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What to send for a quote
When you call or email, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
For canopy cleaning in Harwell, call us on 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Canopy cleaning in Harwell, done properly
We have been cleaning kitchen canopies since we started trading in 2009. As a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, we treat the canopy as one part of a whole system, and we hold CHAS, SafeContractor and ISO 9001. Common call-outs are for a sticky, discoloured canopy and poor capture at the hood, on baffle filters, island canopies and canopy light fittings.
In a smaller place like Harwell, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

When something else is needed
A few issues sit outside what this work can do:
- Ductwork and fans beyond the canopy (those need a full TR19 clean)
- Poor airflow from a fan that needs repair
- A canopy undersized for the equipment
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly.

Signs you need canopy cleaning in Harwell
Filters that are missing, damaged or badly seated leave gaps. More grease reaches the plenum and housing than they’re designed to take, which shows up as heavy deposits when the filters come out.
Keep an eye out for these warning signs:
- Condensation and grease dripping together
- Filters that never seem to stay clean
- Grease channels that no longer drain
- A canopy flagged at an environmental health inspection
Volunteers running a hall kitchen near Church of St Matthew, or anywhere in Harwell, may not know when the extract was last cleaned, and a grease test settles it.

Grease, kitchens and Harwell
Food Standards Agency records list about 17 restaurants, cafés and works canteens and about 4 takeaways within 1.5 miles or so of the middle of Harwell. Every kitchen among them that cooks under a canopy has a hood, plenum and filters collecting grease. Fire safety in Harwell falls to Oxfordshire 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. Kitchens in Harwell get their food hygiene inspections from Vale of White Horse council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
School kitchens, at schools like Harwell Primary School for example, are usually cleaned in the holidays so no lunches are lost. A hospital like Abingdon Community Hospital, about 4.8 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Common questions in Harwell
Do you work at weekends in Harwell?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Harwell needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Can you get to a site in Harwell?
Yes, Harwell is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Will I get a report after the canopy clean?
Before and after pictures go into a report, listing what was cleaned. Where the whole system is cleaned, you also get a TR19 certificate through the BESCA Vent Hygiene Elite portal.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
How long will it take to clean the canopy?
A single canopy with a light build-up is fairly quick, while long canopies, several hoods or heavy deposits take more time. You will know before we start.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
What if parts of the system cannot be reached?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours for most canopies. In a place like Harwell, we fit the visit around your hours.
- We look at the canopy first, from pictures or on a visit.
- Cooking equipment is left to cool and the area under the canopy protected.
- We remove the grease filters and clean the plenum and filter housing.
- We degrease the canopy shell, its seams and the grease troughs.
- Clean filters are refitted and before and after photos go into your report.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
- Tell us the best time to work, such as after service or at a weekend

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Part by part
Wall canopies
Wall canopies sit against a wall over a cooking line. The joint between canopy and wall is a common grease trap, and we clean that join along with the inside of the hood.
School and staff canteen kitchens
Canteens and school kitchens tend to run to a timetable, which makes a canopy clean easy to schedule. Holidays and weekends work well.

What happens if it’s left?
Baked-on grease gets harder to shift the longer it stays. Heat from the range bakes canopy grease into a hard, dark layer, which makes a later clean slower and harder. Light use slows the build-up but does not stop it.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
