Grease filter exchange in Bennetts End
Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. Typical jobs include drips falling from the filters onto equipment and gaps where filters have been removed, across restaurants and pubs, island canopies and baffle filters.
In a smaller place like Bennetts End, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes well under an hour for most canopies, and we clear up before we go. In a smaller place like Bennetts End, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
How to prepare
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

How we price grease filter exchange
There’s no set price list, because no two systems are the same. The quote depends on:
- Whether we need access equipment or extra panels
- How many systems or sites are involved
- One-off work versus a regular cycle
- Parking and loading at the site
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.
Helping us quote
Before you ask for a quote, gather:
- Where the site is and what kind of site it is
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711, or send details by email.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Grease, kitchens and Bennetts End
There are about 105 restaurants, cafés and canteens and about 60 takeaways in and around Bennetts End, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Food hygiene inspections in Bennetts End are the job of Dacorum council’s environmental health team. 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. Fire safety in Bennetts End falls to 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.
For kitchens close to Apsley station, where the day often starts early and ends late, the extract can be cleaned overnight. Where a hall near Saint Benedict, or anywhere in Bennetts End, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What the work involves, part by part
The plenum
Clean filters reduce the grease reaching the plenum, but it’s still cleaned during a full TR19 clean.
Canopy filter housings
The trough or channel under the filters fills with grease. If it needs attention, we’ll tell you.
Leave it or put it right?
Leaving filters too long pushes more grease into the plenum and ducts. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. It’s easy to lose track of when the work was last done on a quieter site.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

Honest limits
We will not sell you work that doesn’t address the problem, so here are the limits:
- Extraction problems caused by the fan rather than the filters
- A canopy that needs a proper clean
- Odours from the discharge that filters won’t stop
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think before booking.

Do you need grease filter exchange in Bennetts End?
Long cooking hours in Bennetts End or anywhere else mean more grease on the filters. Heavy daily use means fast build-up so changes need to come round sooner.
These are the problems we see most often:
- Grease building up behind the canopy filters
- Filter washing that keeps being missed
- A canopy that drips grease
- Filters that leave gaps in the canopy
For schools such as The Reddings Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Bennetts End questions
Can you come to Bennetts End after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Which fire authority looks after Bennetts End?
It’s Hertfordshire Fire and Rescue Service, which covers Bennetts End. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
Is Bennetts End in your area?
Yes. We work in Bennetts End and across Hertfordshire, within our South East and London area. To book, phone us on 0345 646 2711 or email us.
Is filter exchange enough instead of a full extract clean?
It does not. Filters do not catch everything, so grease still reaches the ductwork, so the full system still needs cleaning to TR19.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Are you insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Will we have to shut during the visit?
Not usually. The area we are working in has to be out of use while we are there, so we book a time when it would be closed anyway.
