About kitchen extract cleaning in SG1
A kitchen extract system is far more than the canopy you can see. Beyond the filters run the plenum, the ducts and risers, the fan and the point where air leaves the building, and each part collects grease. Our clean follows the air from canopy to discharge, cleaning to BESA TR19® Grease. The work covers discharge points, canopies and hoods and extract fans, and people most often call us about proof of cleaning requested by an insurer and stale cooking odours from the system.
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a few hours for a small kitchen, longer for a large system.
- We survey the system, from your photos or on site, canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- We work through the system from the canopy to the fan and discharge.
- We re-test, photograph and send your certificate and photo report.

Kitchen extract cleaning around SG1
Kitchens across SG1 cook for very different hours, from all-day town-centre sites to part-time hall and school kitchens. The right interval comes from hours of use and grease readings.
From central London kitchens to coastal hotels and country pubs, London and the South East have every kind of site. The same TR19® standard applies to all of them, in SG1 and beyond.
Stevenage: School kitchens, at schools like Saint Vincent de Paul Catholic Primary School for example, are usually cleaned in the holidays so no lunches are lost. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Lister Hospital is the nearest hospital to Stevenage, about 1.7 miles north-west.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Flag any change in how the extract sounds or works
- Switch the fan on before cooking starts
- Make sure every filter is fitted before cooking
- Keep the baffle filters clean
The kitchen is left clean and ready for the next service. Waste grease and water are contained and removed, so you can start cooking as normal.
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.
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What the work involves, part by part
Restaurant and pub kitchens
Busy restaurant and pub kitchens often cook for long hours, frying and grilling, so their cleaning interval is often 3 or 6 months under BESA guidance. We clean after close or before opening.
Extract fan and discharge
The discharge is where air leaves the building, and grease can collect there too. It’s cleaned as far as safe access allows, and any limits are recorded.
What affects the cost of kitchen extract cleaning
Sites vary more than people expect. The main factors:
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
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 give you a fixed price before work begins.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Why it fails
We often find duct sections that haven’t been cleaned since they were installed. The usual reason is a lack of access panels, so those sections were never reached. That hidden grease keeps building where nobody looks.
Signs it’s time to call us include:
- Rancid smells from grease in the duct
- Heavy grease build-up inside the duct runs
- Missing paperwork after a change of operator
- An extract that has never been cleaned to TR19
FAQs for SG1
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
What do you do with what you remove?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Do insurers need proof of extract cleaning?
Extract grease is fuel for a kitchen fire, so many insurers want evidence it’s being cleaned to TR19. Our certificate and photo report give you that evidence.
Will the clean disrupt our service?
We clean while the kitchen is closed, working evenings, overnight or at weekends to suit you. Equipment needs to be off and cool before any work starts.
Do you work in SG1?
Yes. We work in SG1 and the rest of Hertfordshire, within our South East and London area. For a fixed quote, call 0345 646 2711 or send us an email.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What does a TR19 kitchen extract clean include?
Everything from canopy to discharge: canopy inside and out, plenum, grease filters, ductwork, risers, extract fan and discharge, plus attenuators where fitted. Anything we cannot reach is recorded on the report.
