How we handle grease filter exchange in Bicknacre
Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. That is why the whole system still needs cleaning to TR19 at the right interval. If you have smoke and heat lingering under the hood and blocked baffle filters, we can help, from restaurants and pubs, baffle filters and wall canopies onwards.
Work in a small place like Bicknacre starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What happens if it’s left?
Once filters are saturated, more grease gets past them. The ductwork then loads up faster and grease readings can rise between cleans. Our emergency line runs 24/7, but a planned visit to Bicknacre is calmer for everyone.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before work begins.

Different parts, different methods
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They do not clean themselves as the collected grease builds up between the blades.
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. If it’s bent or greasy, filters won’t seat properly.
Between visits
After the visit, a few habits help the work last:
- Watch for grease drips between visits
- Always run the extract while cooking
- Clean the canopy surfaces regularly
- Make sure we can reach the canopy on exchange day
If the plenum behind the filters looks greasy, we say so. It can be a sign that a full TR19® clean is due, and we can arrange it.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes less than an hour in most kitchens. Rural roads and tight entrances are worth telling us about before a visit to Bicknacre.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
How to prepare
- Clear loose items from the work area
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Signs you need grease filter exchange in Bicknacre
Washing filters by hand doesn’t always get them clean. Grease hides in the folds of a baffle or the layers of a mesh, and a quick rinse leaves it there.
Clients usually contact us when they notice one of these:
- A greasy plenum behind the filters
- Weak extraction at the canopy
- Drips falling from the filters onto equipment
- Filters that come out of the sink still dirty
School kitchens, at schools like Priory Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Bicknacre questions
Can you come to Bicknacre after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Who carries out food hygiene inspections in Bicknacre?
The local authority for Bicknacre is Chelmsford council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you clean our existing filters instead?
Yes. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. We make sure the canopy is ready for service either way.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How much does a filter exchange service cost?
It depends on the number and type of filters and how often they’re changed. We will send you a fixed quote, usually within one working day.
Who is responsible for fire safety on the premises?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you’re not sure, check your lease and fire risk assessment.
What should go in our maintenance log?
Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. A single log for each site works best.
How often should grease filters be changed?
That depends on the cooking. Kitchens that fry and grill all day need changes more often than lighter ones. We agree the interval with you.
What affects the cost of grease filter exchange
We quote each job individually. This is what makes a difference:
- The number of sites or systems

- The condition of the system
- Where the site is and how we reach it
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
What we need to know
To help us quote quickly, please include:
- Problems your staff have spotted
- The times we could work without disrupting the site

What else we do in Bicknacre
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Grease, kitchens and Bicknacre
Food Standards Agency records list about 4 cafés, restaurants and staff canteens within roughly a mile and a half of the centre of Bicknacre. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. It’s Chelmsford council that sends environmental health officers to food businesses in Bicknacre. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Essex County Fire and Rescue Service covers Bicknacre. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens, like those at hospitals such as Baddow Hospital (about 3.6 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a church or community hall kitchen, near St Andrew's or elsewhere in Bicknacre, its extract still collects grease from every lunch and event.
