How we handle grease filter exchange in Codicote Bottom
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork, but some grease still passes through as vapour. So the canopy, plenum and ducts still need their full TR19 clean. Typical jobs include staff short of time to wash filters and hand-washed filters that still look greasy, on mesh filters, island canopies and baffle filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Don’t refit a filter that is bent
- Never leave gaps in the filter bank
- Look out for drips from the canopy
- Tell us if the menu or opening hours change
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us for cleaning.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
How we price grease filter exchange
Every site gets its own quote. These are the things that affect it:
- One-off work versus a regular cycle
- Parking and loading at the site
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.
What to send for a quote
When you contact us, it’s useful to have:
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- The site address and the type of premises
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.
Do you need grease filter exchange in Codicote Bottom?
Kitchens in Codicote Bottom, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for filters to fill with grease.
What we are most often called out for:
- Filters left unwashed on busy weeks
- Gaps where filters have been removed
- Poor airflow through the filters
- Bent or damaged filters that do not sit properly
If your kitchen is in a listed or historic building, like the houses around Codicote Bottom (Shaw's Corner is about 1.3 miles south-west), fitting access panels needs care.
What to look for in a quote
- How they set the interval to the next visit
- Whether the quote shows VAT
- Whether the figure could change on the day
- When they can work, and whether that’s outside your opening hours
How the job changes from site to site
The plenum
With good filters, less grease ends up in the plenum, but it’s still cleaned during a full TR19 clean.
Canopy filter housings
Filters sit in a housing or channel in the canopy. If it’s bent or greasy, filters will not seat properly.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes anything from a few minutes to an hour or so, depending on the number of filters, and we clear up before we go. Seeing the system in pictures first means the trip to Codicote Bottom can be planned properly.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- Each visit starts with the used filters being removed.
- 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
- Find the previous report, if there is one
- Arrange a key holder or contact on site
How to get a quote
For a fixed quote, ring 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
Advice
Common questions in Codicote Bottom
Do you do school kitchen extract cleaning in Codicote Bottom in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Codicote Bottom. Send us your term dates when you ring 0345 646 2711 or send us an email, and we’ll fit the work in.
Which environmental health team covers Codicote Bottom?
Kitchens in Codicote Bottom are inspected by North Hertfordshire council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How much does a filter exchange service cost?
The cost depends on your filters and the schedule. We will give you a fixed quote once we know your canopies.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Does a filter exchange replace TR19 cleaning?
No. Filter exchange works between full cleans, not instead of them. TR19® cleaning covers the canopy, plenum, ductwork and fan and comes with a certificate and photo report.
What happens if you cannot reach some of it?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
What paperwork should we keep on file?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Why it’s worth doing now in Codicote Bottom
Washing filters in-house is an option for kitchens in Codicote Bottom, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
