Grease Filter Exchange in North Lee
Grease filter exchange across North Lee and nearby, booked around your opening hours and signed off in writing with pictures.
- Grease dripping from the canopy
- Hand-washed filters that still look greasy
- Blocked baffle filters
What happens on the day
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 the area around the work is covered and protected. The work itself takes a few minutes per canopy, longer for a large kitchen with several canopies. In a small place like North Lee, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool

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, you get a fixed price before we start.
Advice
Grease filter exchange in North Lee, done properly
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. If you have a greasy plenum behind the filters and filters that leave gaps in the canopy, we can help, from baffle filters, school and hospital kitchens and mesh filters onwards.
In a village or hamlet like North Lee, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What a clean won’t put right
Before you book, it helps to know what’s not included:
- A canopy too small for the cooking beneath it
- Grease behind the filters that a swap can’t remove
- Smell complaints that need odour control equipment
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think.

Signs you need grease filter exchange in North Lee
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
If you notice any of these, it’s worth a diagnosis:
- A greasy plenum behind the filters
- Missing filters in the filter bank
- Blocked baffle filters
- A canopy that drips grease
Bursars and site managers at schools such as Stoke Mandeville Combined School tend to book extract cleaning for when the kitchen is empty.

Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Fixed quotes for grease filter exchange in North Lee
The price is fixed before any work begins. It takes into account:
- Whether several sites go on one quote
- Where the site is and how we reach it
- Any permits to work or inductions
- What state the system is in
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Detail shots of panels, filters and grilles
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
North Lee kitchens: local notes
The FSA’s food hygiene register shows about 4 restaurants, cafés and works canteens across North Lee and its immediate surroundings (about a mile and a half). Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. North Lee sits within the area of Buckinghamshire 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. In North Lee, food businesses are inspected by environmental health officers from Buckinghamshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. 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. Healthcare kitchens, like those at hospitals such as Stoke Mandeville Hospital (about 1.7 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.

North Lee questions
Which fire and rescue service is responsible for North Lee?
Buckinghamshire Fire and Rescue Service is the fire and rescue service for North Lee. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can school kitchens in North Lee be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of North Lee. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which records should we keep?
Everything that shows the system is looked after: reports, certificates, pictures and your own cleaning or check logs. A single log for each site works best.
Will we have to stop cooking for a filter change?
An exchange does not take long, and can be booked outside service times. The clean set goes in as soon as the dirty one comes out.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Is North Lee in your area?
Yes. We cover North Lee and the rest of Buckinghamshire, within our South East and London area. For a fixed quote, phone us on 0345 646 2711 or send us an email.
What happens to the dirty filters?
We take them away to be cleaned, so your staff don’t have to wash them. A clean set is fitted in their place.
What happens if you can’t reach some of it?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Part by part
Baffle filters
A clogged baffle filter restricts airflow. Swapping them for a clean set restores it.
Mesh filters
Older or smaller canopies often use mesh filters. They can be on the same exchange schedule as baffle filters.
Between visits
Once we’ve finished, these simple steps help:
- Let us know if your cooking hours increase
- Keep every filter in place during service
- Look out for drips from the canopy
- Clear anything stored on or near the canopy
Between visits, check that every filter is still in place. Gaps let grease into the plenum so tell us if you need a replacement.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
