Extraction cleaning - schools
A school kitchen cooks hard in a short lunch, and all that cooking loads the extraction canopy, filters and fan with grease. That grease is fuel - and it sits in a building occupied by hundreds of children. A kitchen fire drawn up into a greased duct is exactly the scenario a school's fire precautions exist to prevent, which makes keeping the extract clean part of the school's fire-safety duty, not just its hygiene. Here is how extraction cleaning and fire safety connect in a school kitchen, and how the work fits the holidays. This is general commentary.
The short answer
Fire safety is where extraction cleaning matters most in a school, and the link is direct. Why the extract is a fire risk. A school kitchen cooks intensely in a short lunch - fryers, ovens and grills going hard to feed hundreds in under an hour - and that hard cooking loads the extraction quickly: the canopy, the baffle filters, the plenum behind them and the fan all take on grease. Grease is not an inert deposit; it is fuel. A greased-up extract sitting over a live flame is a fire waiting for an ignition, and a kitchen fire is one of the most common ways a fire starts in a catering building. Why it matters more in a school. The building the extract sits in is occupied by hundreds of children and staff, and a school's fire precautions - including a planned, practised evacuation - are built around getting them out safely. A kitchen fire that ignites the grease and is drawn up into a greased duct can spread through the structure fast and unseen, threatening exactly the safe evacuation the precautions depend on. So the fire stakes in a school are high, and concealed grease in the extract is a real part of the risk. A fire-safety duty, not just hygiene. That is why keeping the extract clean is part of the school's fire-safety duty. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and manage the fire risk, and grease in the kitchen extract is a recognised part of it - a fire risk assessor looking at the kitchen expects to see the extract cleaned to a standard, with a current certificate and photographs, not a wiped canopy over an unknown, greased duct. So extraction cleaning belongs in the school's fire management, alongside its alarms, its extinguishers and its evacuation plan. Doing it in the holidays. The school holidays are the natural window: with the kitchen closed, the whole system can be stripped, soaked, scraped and degreased - filters, canopy, plenum and fan - and certified, without disrupting service. A contractor who understands schools plans the work into the holiday, sends DBS-checked engineers who can work on a school site, and leaves the certificate, grease-depth readings and before-and-after photographs for the fire file. So extraction cleaning and fire safety in a school kitchen are the same job - removing the fire fuel, and evidencing it, to protect a building full of children. This is general commentary on extraction cleaning and fire safety in schools.
Key points
Grease is fire fuel
The link between extraction cleaning and fire safety starts with what grease is: fuel. A school kitchen cooks intensely in a short lunch - fryers, ovens and grills going hard to feed hundreds in under an hour - and that hard cooking loads the extraction quickly: the canopy, the baffle filters, the plenum behind them and the fan all take on grease. It builds fast because the service, though short, is heavy.
And a greased-up extract sitting over a live flame is not just a performance problem (a greased fan pulls less, and the kitchen goes hot and smoky) - it is a fire risk, because the grease is fuel waiting for an ignition. A kitchen fire is one of the most common ways a fire starts in a catering building, and the extract is where the fuel accumulates. So a hard lunch loads the extract with fuel, which is why grease is fire fuel. This is general commentary.
The stakes in a school
The reason the fire fuel matters so much in a school is the building it sits in. A school is occupied by hundreds of children and staff, and its fire precautions - including a planned, practised evacuation - are built around getting them all out safely. A kitchen fire that ignites the grease and is drawn up into a greased duct can spread through the structure fast and unseen, threatening exactly the safe evacuation the precautions depend on.
So the fire stakes in a school are high, and concealed grease in the kitchen extract is a real part of the risk - not a background maintenance detail. A fire in the kitchen is bad anywhere; in a building full of children mid-lesson it is the emergency everything is arranged to prevent. That is why the extract's grease load is a fire-safety concern, not just a hygiene one. So a fire load in a building full of children is the stakes in a school. This is general commentary.
Part of the fire-safety duty
Because the grease is fire fuel in an occupied building, keeping the extract clean is part of the school's fire-safety duty. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person - the school, the local authority or the academy trust - must assess and manage the fire risk, and grease in the kitchen extract is a recognised part of it.
A fire risk assessor looking at the kitchen expects to see the extract cleaned to a standard, with a current certificate and photographs to show it - not a wiped canopy over an unknown, greased duct. So extraction cleaning belongs in the school's fire management, alongside its alarms, extinguishers and evacuation plan - and the certificate is the evidence that the fire fuel is being controlled. So the Fire Safety Order and the evidence a risk assessor wants make it part of the fire-safety duty. This is general commentary.
Cleaning it in the holidays
The school holidays are the natural window to clean the extract, because the kitchen is closed. With no service to work around, the whole system can be cleaned thoroughly - the filters stripped, soaked and scraped, the accessible duct scraped back, and the plenum and fan degreased - and the result certified, without disrupting a single lunch. Cleaning the whole system matters for fire safety: it is the fan and duct grease, not just the filters, that carries the fire load, so filters alone are not enough.
Planning the work into the holiday, rather than squeezing it into a term-time evening, is how a school gets the thorough job that actually removes the fire fuel. And the kitchen comes back from the break clean, fire-safe and certified for the new term. So the whole system, stripped and degreased while closed, is how it is cleaned in the holidays. This is general commentary.
The evidence for the fire file
Extraction cleaning for fire safety ends with the evidence, because the school has to be able to show the fire fuel is controlled. The school receives a dated certificate to the recognised standard, the grease-depth readings taken before and after, and before-and-after photographs of the internal run - the record a fire risk assessor expects, and the evidence the school needs for its fire file.
For a school, or a trust running several, that record kept per kitchen on a reliable schedule - with a next-due date that lands the next clean in the next holiday - is what shows the extract's fire risk is managed continuously, not just once. Our engineers are DBS-checked and can work on a school site, and we leave that evidence after every clean. So a certificate and readings that show the fuel is controlled is the evidence for the fire file. This is general commentary.
Questions
Because grease is fuel, and a school is a building occupied by hundreds of children. A school kitchen's hard, short lunch loads the extraction canopy, filters and fan with grease quickly, and a greased-up extract over a live flame is a fire waiting for an ignition. A kitchen fire drawn up into a greased duct can spread through the structure fast and unseen, threatening the safe evacuation a school's fire precautions depend on. So the grease is a real part of the fire risk in a school, not just a hygiene issue. So it is a fire risk because grease is fuel in an occupied building. This is general commentary.
Yes - under the Regulatory Reform (Fire Safety) Order 2005 the responsible person (the school, local authority or trust) must assess and manage the fire risk, and grease in the kitchen extract is a recognised part of it. A fire risk assessor expects to see the extract cleaned to a standard, with a current certificate and photographs, so extraction cleaning belongs in the school's fire management alongside its alarms, extinguishers and evacuation plan. So yes - it is part of the fire-safety duty, not just hygiene. This is general commentary.
The school holidays are the natural window, because the kitchen is closed and the whole system can be stripped, degreased and certified without disrupting service. Cleaning the whole system - filters, canopy, plenum and fan - is what actually removes the fire fuel, since it is the fan and duct grease that carries the fire load, not just the filters. Planning it into the holiday gives the thorough job, and the kitchen comes back fire-safe and certified for the new term. So it should be cleaned in the holidays, thoroughly. This is general commentary.
The whole system - filters, canopy, plenum, fan housing and impeller, and the accessible duct. For fire safety this matters: it is the fan and duct grease, not just the filters, that carries the fire load, so cleaning the filters alone leaves fuel in the system. Cleaning the whole extract removes the fire fuel and restores the airflow, and it is what the certificate and grease-depth readings then evidence. So we clean the whole system, which is what fire safety needs. This is general commentary.
A dated certificate to the recognised standard, the grease-depth readings taken before and after, and before-and-after photographs of the internal run - the record a fire risk assessor expects and the evidence the school needs for its fire file. For a school or trust, kept per kitchen on a reliable schedule with a next-due date, it shows the extract's fire risk is managed continuously. So you get the certificate, readings and photographs for the fire file. This is general commentary.
Yes - our engineers are DBS-checked and inducted, so they are people the school is comfortable having on site around children, including in the holidays when the work is best done. They coordinate with the caretaking team and any other holiday works. So yes - DBS-checked for a school site. This is general commentary.
A greasy school kitchen extract is fire fuel in a building full of children, so cleaning it is part of the school's fire-safety duty. We clean the whole system - filters, canopy, plenum and fan - planned into the holidays by DBS-checked engineers, and leave the certificate and readings for your fire file. Ask us to clean your school kitchen's extraction. This is general commentary on extraction cleaning and fire safety in schools.
