About our grease filter exchange in Cassiobury
Each visit is quick and tidy. The greasy filters come out, clean ones go in and make sure there are no gaps between them. Anything that needs attention is pointed out. If you are dealing with hand-washed filters that still look greasy and damaged filters letting grease past, we can put it right.
For a smaller kitchen near Cassiobury, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Cassiobury questions
Can a school canteen extract in Cassiobury be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 39 schools and colleges on the FSA’s register within roughly a mile and a half of Cassiobury, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or drop us a line with the dates the site is empty.
Is Cassiobury within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How often should grease filters be changed?
It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than lighter ones. We set a schedule that suits your kitchen.
Do you clean filters as well as exchanging them?
Yes, filters can be cleaned on a schedule as well as exchanged. We will explain the options when we quote.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How long does the visit take?
It depends on the size of the system, but for a typical site it takes less than an hour in most kitchens. We’ll give you a better idea when we quote.
Do you recommend a next date?
Yes. How often depends on use and condition and the report sets out why.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
How it works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Getting to the system matters more than parking in a place like Cassiobury, so let us know how to reach it.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
Getting a quote
For a fixed quote, phone us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
Advice
Grease filter exchange in Cassiobury: the local picture
The FSA’s food hygiene register shows about 218 restaurants, cafés and works canteens and about 65 takeaways and sandwich shops across Cassiobury 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. Cassiobury is covered by Hertfordshire 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. Kitchens in Cassiobury get their food hygiene inspections from Watford council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
For kitchens close to Watford Junction station, where the day often starts early and ends late, the extract can be cleaned overnight. Where a hall near St John's Church, or anywhere in Cassiobury, 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 Watford General Hospital about 0.8 miles south, the extract may need cleaning more often than a part-time kitchen.
Cassiobury is about 1 mile south of Watford, in Hertfordshire. Anywhere in WD17, we can carry out grease filter exchange at your premises. Cassiobury is one of 381 towns, villages and districts in Hertfordshire where we work for commercial clients. There’s also a page for London, roughly 17 miles from Cassiobury.
Grease filter exchange in WD17, WD18 and WD24 follows the same survey, fixed quote and written report as everywhere else we cover.

Around Cassiobury
Typical jobs here are in premises near Croxley Danes School, Cassiobury Park and The Estcourt Tavern. Cassiobury has its own railway station: Watford Junction station.

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 the report can go to both.
Facilities teams in offices, schools and healthcare sites book us too in Cassiobury and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
How the job changes from site to site
School, care home and staff kitchens
Even kitchens with fixed meal times build up grease though normally at a gentler pace.
Canopy filter housings
The trough or channel under the filters fills with grease. If it needs attention, we will tell you.
Aftercare tips
To keep the system working properly between visits:
- Wipe the outside of the canopy as part of daily cleaning
- Keep the extract on whenever the range is in use
- Keep filter exchange and TR19 cleaning on the same plan
- Watch for grease drips between visits
Once the clean filters are in, the kitchen can cook right away. The dirty set leaves with us for cleaning.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
Honest limits
To be straight with you, there are a few things this work won’t fix:
- A canopy that needs a proper clean
- A noisy or failed extract fan
- An extract that was undersized from the start
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think before you book.

What else we do in Cassiobury
How we price grease filter exchange
We do not publish a price list, because no two systems are the same. What we look at:
- Site requirements such as sign-in and permits
- How many systems or sites are involved
- The scale of the work
- A single visit or a regular plan
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Your opening hours and when the area is out of use
- The site address and the type of premises
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
