Hertfordshire · Grease filter exchange
Grease filter exchange in Cottered, Hertfordshire
A scheduled grease filter exchange, swapping dirty canopy filters for clean ones for commercial sites in Cottered and across Hertfordshire. CHAS, SafeContractor and ISO 9001, and fully insured.
- Blocked baffle filters
- Poor airflow through the filters
- Grease collecting in the filter channels
What we do, step by step
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. We agree a date with you, plan the drive to Cottered and turn up when the site is quiet.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Arrange a key holder or contact on site
- Let us know about permits to work or site inductions

Advice
About our grease filter exchange in Cottered
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 a canopy that drips grease and weak extraction at the canopy, we can put it right.
Somewhere as small as Cottered, 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, whatever the size of the place.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Fixed quotes for grease filter exchange in Cottered
Sites vary more than people expect. The main factors:
- Any permits to work or inductions
- Whether several sites go on one quote
- How easy every part is to reach
- What state the system is in
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
What to send for a quote:
- The times we could work without disrupting the site
- The postcode and the type of business
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or send us an email.

We cover Cottered, about 31 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Hertfordshire Fire and Rescue Service covers Cottered. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Church and community hall kitchens, near Parish Church of St John the Baptist or anywhere around Cottered, are easy to forget, but their extracts collect grease like any other.

Questions from Cottered
Do you work at weekends in Cottered?
Yes, evening, overnight and weekend work is normal for us. That way a site in Cottered doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711, or email photos, mention when the site is quiet.
Who is the fire and rescue service for Cottered?
Fire safety enforcement in Cottered is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What should go in our maintenance log?
Every certificate and report from each visit, filed in the maintenance log with your in-house cleaning records. BESA advises that certificates record the date, location and technician.
Do you recommend a next date?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.
Who has the legal duty for fire safety?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What’s the right interval for changing filters?
The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long and we will adjust it.
Will we have to shut during the visit?
Not normally. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Honest limits
Before booking, it helps to know what’s not included:
- Extraction problems caused by the fan rather than the filters
- An extract that was undersized from the start
- A heavily greased plenum or canopy, which needs cleaning to TR19
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly.
What we work on in Cottered
- Mesh filters
- Island canopies
- Baffle filters
- School and hospital kitchens
- Wall canopies
- Restaurants and pubs
Why act early in Cottered
When filters block, extraction suffers. Heat and fumes hang in the kitchen, and the fan works harder to pull air through. Keeping filters clean keeps the extract working properly. In a place like Cottered, ductwork and fans are easy to forget until something goes wrong.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or email photos, and we will explain what it covers.
Why book with us
- In business since 2009
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Larger estates can be phased building by building around the people who use them.
Do you need grease filter exchange in Cottered?
Cooking vapour carries grease into the canopy. The filters catch much of it so they gradually clog until the air can barely get through.
Clients normally contact us when they notice one of these:
- Grease collecting in the filter channels
- Hand-washed filters that still look greasy
- Damaged filters letting grease past
- Blocked baffle filters
For schools such as Freman College, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
What your quote should include
- What records you will receive afterwards
- Exactly which parts of the system are covered
- How they set the interval to the next visit
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
