Grease filter exchange in Willian, done properly
Across Willian, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, from a single canopy to several. We can come before or after service so nobody has to stop cooking. If you have a canopy that drips grease and grease building up behind the canopy filters, we can put it right, from mesh filters, school and hospital kitchens and wall canopies onwards.
Somewhere as small as Willian, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Leave it or put it right?
When filters block, extraction suffers. The kitchen gets hotter and smokier, and the fan works harder to pull air through. A regular exchange keeps the airflow where it should be. A planned visit to Willian is easier to arrange than an emergency callout.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
Why us?
- Every job surveyed first
- Full insurance on every job
- Trading since 2009
- Evenings, overnight and weekends, plus 24/7 emergency callout
Do you need grease filter exchange in Willian?
Long cooking hours in Willian or anywhere else mean more grease on the filters. A kitchen that cooks all day loads its filters quickly so changes need to come round sooner.
The symptoms we’re asked about most are:
- Poor airflow through the filters
- Grease collecting in the filter channels
- Filters so greasy the air can barely pass
- Grease left in baffles after washing
Bursars and site managers at schools such as Lordship Farm Primary School tend to book extract cleaning for when the kitchen is empty.

What else we do in Willian
What affects the cost of grease filter exchange
The survey tells us what the work involves. We look at:
- A single visit or a regular plan
- Travel, parking and unloading
- Access, including roofs, risers and ceiling voids
- The times the site is available
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
What to send for a quote
Before you ask for a quote, gather:
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- Photos showing the whole system and its surroundings
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
FAQs for Willian
Can you get to a site in Willian?
Yes, Willian is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can you work in Willian outside opening hours?
Yes. We work evenings, overnight and at weekends. That way a site in Willian doesn’t have to lose a day’s trading. Just give us a ring on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Can we skip TR19 cleans if the filters are changed regularly?
It does not. Some grease passes the filters as vapour and settles in the ducts and the whole system still needs its TR19 clean.
Can damaged filters stay in the canopy?
A badly damaged filter should be replaced. We will tell you which ones and why on the visit.
What does grease filter exchange cost?
Filters, canopies and how often you need visits all affect the price. Send us details or photos and we will quote, usually within one working day.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. Insurers, fire officers and EHOs may all ask to see them, so keep them where they can be found quickly.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Is there a cleaning option for the filters we have?
Yes, filters can be cleaned on a schedule as well as exchanged. We will talk you through which suits your kitchen when we quote.
How the visit works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Seeing the system in pictures first means the trip to Willian can be planned properly.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- We flag any damaged filters or anything wrong with the canopy.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
Ask for a quote
For a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We typically come back within one working day.

Willian kitchens: local notes
Look up Willian on the FSA’s food hygiene register and you will find about 49 cafés, restaurants and staff canteens and about 25 sandwich bars and takeaways within roughly a mile and a half of the centre of Willian. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Willian is covered by Hertfordshire 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. It’s North Hertfordshire council that sends environmental health officers to food businesses in Willian. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Willian is Lister Hospital, about 2.5 miles south. Where a hall near Church of All Saints, or anywhere in Willian, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Between visits
To keep the system working properly between visits:
- Wipe the outside of the canopy as part of daily cleaning
- Look out for drips from the canopy
- Report damaged filters so they can be replaced
- Do not let the full clean slip because filters are changed
The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so the filters do their job.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
