Grease filter exchange in Mill End
Grease filters are the first line of defence in a kitchen extract. Their job is to stop grease getting further into the system, but only while they’re reasonably clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. If you have missing filters in the filter bank and hand-washed filters that still look greasy, we can help.
In a smaller place like Mill End, 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. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Never cook with the extract switched off
- Report damaged filters so they can be replaced
- Let us know if your cooking hours increase
- Clear anything stored on or near the canopy
Between visits, check that every filter is still in place. Gaps let grease into the plenum so tell us if you need a replacement.
A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up behind the canopy.
Your questions about grease filter exchange in Mill End
Do you work in villages like Mill End?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can school kitchens in Mill End be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Mill End. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
Do I get a report after the visit?
Yes. You get a written report with pictures after each visit, showing what was done, anything we couldn’t reach and when the next visit is due. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
Does a filter exchange replace TR19 cleaning?
No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system, with a certificate and photo report.
What should go in our maintenance log?
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.
How regularly do grease filters need exchanging?
It depends on how much and what the kitchen cooks. Heavy cooking means more frequent changes than lighter ones. We agree the interval with you.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.

- Extraction problems caused by the fan rather than the filters
- Greasy ducts and risers that a filter change will not reach

The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. Getting to the system matters more than parking in a place like Mill End, so let us know how to reach it.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.
Advice
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare in Mill End and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
