Northwood questions
Do you clean school canteen extracts around Northwood out of term?
Yes. Half-terms and the summer break are the natural time for school work. Around Northwood, the Food Standards Agency lists about 31 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Does being near the coast affect grease filter exchange in Northwood?
Yes, to a degree: at about 2 miles from the coast, Northwood gets salt-laden air that corrodes metal faster. Outdoor metalwork near the sea is worth inspecting at every visit.
Which grease filters does the service cover?
Baffle filters and mesh filters. Mention how many canopies you have when you get in touch, or we will check on the first visit.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We’ll tell you which ones and why on the visit.
What paperwork should we keep on file?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.
How long does grease filter exchange take?
The work itself takes anything from a few minutes to an hour or so, depending on the number of filters. Bigger or more complicated systems take longer, and the quote will say how long.
Grease filter exchange for kitchens and businesses in Northwood
Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. If you’re dealing with filters so greasy the air can barely pass and missing filters in the filter bank, we can put it right, from school and hospital kitchens, wall canopies and baffle filters onwards.
In a smaller place like Northwood, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so the interval is set by hours of use and grease readings.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Aftercare tips
How long the results last depends on use and care. We suggest:
- Look out for drips from the canopy
- Make sure no filter is left out
- Don’t refit a filter that’s bent
- Tell us if the menu or opening hours change
The canopy looks cleaner and the air moves better from the moment they’re fitted. Keep the extract running while you cook so the filters do their job.
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.
What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a short visit, depending on how many filters the canopies hold, and the area is cleaned down before we leave. Tell us when your site near Northwood is quiet and the visit will be booked for then.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards

What affects the cost of grease filter exchange
Before we fix a price, we need to know a few things. We check:
- Site requirements such as sign-in and permits
- A single visit or a regular plan
- The scale of the work
- What state the system is in
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 we start.
What to send for a quote
There’s no need for technical detail. Just send:
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
Part by part
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease is thrown out of the airstream and collects on the baffles.
Busy restaurant and pub kitchens
High-output kitchens clog filters quickly. Their exchange schedule is typically the tightest.
Grease filter exchange in Northwood: the local picture
At about 2 miles from the coast, Northwood is close enough for sea air to matter. Salt air speeds up corrosion of roof-level fans, discharge cowls and their fixings. Food Standards Agency data counts about 68 restaurants, cafés and works canteens and about 41 takeaways and sandwich shops within 1.5 miles or so of the middle of Northwood. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Food hygiene inspections in Northwood are the job of Thanet council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you cook for passing trade around Ramsgate station, the extract can be cleaned between your last and first customer. Bursars and site managers at schools such as Dame Janet Primary Academy tend to book extract cleaning for when the kitchen is empty. A hall kitchen that only cooks for events, whether near St Mark's Church or elsewhere in Northwood, still needs its extract cleaned, just less often.

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
