- Grease dripping from the canopy or filters
- An extract that no longer clears the smoke
Leave it or put it right?
Grease build-up causes everyday problems too. Blocked filters and narrowed ducts slow the airflow, leaving the kitchen hot and smoky and the fan strains to keep up. Grease drips, smells and condensation are common next. Somewhere as small as North Lee, losing a kitchen or building to a fault is felt by everyone who uses it.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.

Questions from North Lee
Who is the fire and rescue service for North Lee?
Fire safety enforcement in North Lee is handled by Buckinghamshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can the work in North Lee be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in North Lee needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Do you work in North Lee?
Yes. We work in North Lee and across Buckinghamshire, as part of our work across South East England and London. To book, call 0345 646 2711, or send details by email.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then give us a ring on 0345 646 2711 or use the quote form.
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. Where we cannot see enough, we arrange a survey.
What does a TR19 kitchen extract clean include?
We clean every part the grease travels through. That means canopy, plenum, filters, ducts, risers, fan and discharge, reached through access panels where necessary.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Never cook with filters missing or out of place
- Tell us when the extract starts to drip or smell
- Empty any grease troughs or cups on the canopy
- Switch the fan on before cooking starts
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.
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.
What affects the quote in North Lee
Sites vary more than people expect. The main factors:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Grease, kitchens and North Lee
According to Food Standards Agency records, there are about 3 pubs and bars within about 1.5 miles of central North Lee. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. The fire and rescue service for North Lee is Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Environmental health officers from Buckinghamshire council inspect food businesses in North Lee. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Where a hall near Church of St Mary, or anywhere in North Lee, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a healthcare site, such as a hospital like Stoke Mandeville Hospital about 1.7 miles north, the extract may need cleaning more often than a part-time kitchen.
North Lee is about 3 miles south of Aylesbury, in Buckinghamshire. North Lee gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Across Buckinghamshire, we cover 263 places, North Lee among them. There’s also a page for Milton Keynes, roughly 18 miles from North Lee.
Kitchen extract cleaning in HP22 is surveyed, quoted and booked the same way as anywhere else. Other places close to North Lee include Nash Lee (1 mile south-east), Terrick (1 mile south-east), Chalkshire (1 mile south-east), Stoke Mandeville (1 mile north-east) and Ellesborough (1 mile south).

Local landmarks in North Lee
In North Lee, that means kitchens and buildings near The Mandeville School, among other places. The nearest railway station is Stoke Mandeville station, roughly 1.1 miles north-east. A little further out are National Paralympic Heritage Centre (1.9 miles north) and Little Kimble Motte (1.7 miles south). Not far away are Brush Hill Local Nature Reserve and Beacon Hill.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When to call us in North Lee
Grease in the extract matters because it burns. Flames from a pan or grill can be pulled into the canopy by the fan, and once grease in the duct catches, fire can spread through the building’s ductwork. That’s why controlling extract grease belongs in the fire risk assessment.
It’s time to book a visit if you see:
- An overdue clean flagged by an EHO or fire officer
- Fat running down the canopy edge
- An extract that has never been cleaned to TR19
- Heavy grease build-up inside the duct runs
If you look after a school kitchen, at a school such as Stoke Mandeville Combined School or anywhere near North Lee, the holidays are the usual time for a TR19® clean.
What to look for in a quote

What the work involves, part by part
Canopy and plenum
Grease meets the system first at the canopy and the plenum behind the filters. We clean both inside and out, including the filter housing.
Ductwork and risers
Risers take the extract up through floors to roof level, and grease runs down their walls and pools at the base. Access panels along the riser let us clean it in sections.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a few hours for a small kitchen, longer for a large system. The timing of a visit to North Lee is set by you, and the travel is our side of the planning.
- Diagnosis comes first, with a survey of the system and how it’s reached.
- Grease readings set the baseline, and a fixed quote follows.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- The treatment: heavy grease scraped out, then every part degreased to TR19® Grease.
- The sign-off: post-clean readings, a TR19 certificate and a photo report with the next clean date.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
