Commercial kitchen extraction cleaning in St Clement's
A closed kitchen isn’t earning, so the timing of a clean matters. We work evenings, overnight and at weekends, or during holidays where a site closes for them. Equipment is switched off and left to cool, the area is sheeted, and the kitchen is handed back ready to cook. Typical jobs include ductwork thick with old, hardened grease and extraction mentioned at an environmental health visit, on canopies and hoods, discharge points and horizontal duct runs. Kitchens in St Clement's book us for TR19 cleaning for three reasons: the insurer asked, the EHO asked, or the canopy is dripping. Either way, the answer is the same: a proper clean and the paperwork to match.
Each job starts with a look at where grease has built up: grease readings at set points tell us where the heaviest deposits are, and readings afterwards go into your report.
In a smaller place like St Clement's, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Fixed quotes for kitchen extract cleaning in St Clement's
Before we fix a price, we need to know a few things. We look at:
- How many systems or sites are involved
- The condition of the system
- The size of the system
- Whether we need access equipment or extra panels
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.
Helping us quote
When you call or email, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
How the job changes from site to site
Canopy and plenum
The canopy catches the vapour, and the plenum behind the filters is where it first condenses. Both are scraped and degreased inside and out, including the filter housing.
Schools, hospitals and care homes
School, hospital and care home kitchens often have fixed hours and long holidays, so cleans can be booked when the kitchen is closed. The certificate and report suit estates and compliance files.

What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What a clean won’t put right
We’d rather tell you now than book work that won’t help, so here are the limits:
- Extraction that cannot cope with the cooking because of its design
- A broken extract fan that won’t run
- Faulty fire dampers in the duct
If you’re not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer.
Where we work
- Discharge points
- Vertical risers
- Canopies and hoods
- Horizontal duct runs
- Plenums and filters
- Extract fans
Aftercare tips
To keep the system working properly between visits:
- Wipe the canopy down at the end of each day
- Flag any change in how the extract sounds or works
- Refit filters properly after cleaning
- Keep the extract on whenever the range is lit
The report gives a recommended date for the next clean, set from your daily cooking hours and the readings we took. We can put the system on a 3, 6 or 12-monthly plan, so the date isn’t missed.
Stick to the cleaning interval on the certificate. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.
How the visit works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes anything from a few hours to a full night, depending on the size of the system. For a site near St Clement's, the work is booked around your opening hours, evenings and weekends included.
- We survey the system first, from your pictures and details or on a site 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.
- The whole route is cleaned, from the canopy through the ductwork to the fan and the discharge.
- We test again, photograph the result and issue your TR19 certificate and photo report.
Preparing for the visit
- Let us know when the site is closed or quiet
- Let us know about parking and loading
- Move anything stored near the system
Getting a quote
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.

Questions from St Clement's
Can a school canteen extract in St Clement's be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around St Clement's, the Food Standards Agency lists about 79 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Who inspects food businesses in St Clement's?
Food hygiene inspections in St Clement's are carried out by Oxford City council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
How long does it take to clean a kitchen extract system?
That depends on the size of the system, the amount of grease and the number of access points. As a guide, it takes a few hours for a small kitchen, longer for a large system.
Are you a BESCA Vent Hygiene Elite member?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we’re fully insured.
What’s the right cleaning interval for a kitchen extract?
Under BESA guidance, the minimum depends on how long you cook each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
What happens if it’s left?
Grease that is left only gets thicker. BESA guidance says the mean should not go above 200 microns between cleans, and anywhere reaching 500 microns or more needs a spot clean straight away. The longer it’s left, the bigger the job becomes. Even a site near St Clement's that is only busy part of the week needs its system checked on a schedule.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or use the quote form, and we will explain what it covers.

Kitchen extract cleaning around St Clement's
The Food Standards Agency lists about 100 pubs, bars and clubs and about 16 hotels and B&Bs as registered food businesses within about 1.5 miles of central St Clement's. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Environmental health officers from Oxford City council inspect food businesses in St Clement's. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for St Clement's is Oxfordshire 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 St Clement's Church, or anywhere in St Clement's, may not know when the extract was last cleaned, and a grease test settles it. If you run catering at a historic house or estate in the area (Holywell Manor is about 0.5 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning. If you run catering at a healthcare site, such as a hospital like Warneford Hospital about 0.8 miles east, the extract may need cleaning more often than a part-time kitchen.
