Common problems we fix in Henhurst
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up so changes need to come round sooner.
These are the problems we see most often:
- Smoke and heat lingering under the hood
- Grease dripping from the canopy
- Missing filters in the filter bank
- A greasy plenum behind the filters
School kitchens, at schools like Singlewell Primary School for example, are normally cleaned in the holidays so no lunches are lost.

About our grease filter exchange in Henhurst
We set up grease filter exchange for kitchens in Henhurst on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. We agree the interval with you at the start. The work covers wall canopies, school and hospital kitchens and baffle filters, and common reasons people get in touch are grease left in baffles after washing and grease filters clogged with grease.
Somewhere as small as Henhurst, 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.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Always run the extract while cooking
- Wipe the outside of the canopy as part of daily cleaning
- Make sure no filter is left out
- Tell us if the menu or opening hours change
Your next visit is scheduled before we leave. If the kitchen gets busier, the interval can be shortened to match.
If cooking has stepped up, the filter schedule should too. Adjusting the schedule now prevents a build-up in the ducts.
Henhurst kitchens: local notes
The FSA’s food hygiene register includes about 6 pubs, bars and clubs within 1.5 miles or so of the middle of Henhurst. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Food hygiene inspections in Henhurst are the job of Gravesham council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Henhurst falls to Kent Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Cobham College is about 1 mile south-east), access may need planning. Healthcare kitchens, like those at hospitals such as Gravesham Community Hospital (about 3 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.
Henhurst is about 2 miles south of Gravesend, in Kent. Whether your site is in the middle of Henhurst or further out, we cover grease filter exchange for every kind of premises, from a single unit to a large public building. Our Kent coverage runs to 922 places, Henhurst among them. Maidstone is in our area too, around 11 miles away.

Why act early in Henhurst
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Keeping filters clean takes some of that fuel away. Planning a trip to Henhurst ahead is easier for everyone than a rushed one.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

What affects the cost of grease filter exchange
The diagnosis comes before the price. We look at:
- Whether several sites go on one quote
- Any permits to work or inductions
- Parking and loading at the site
- What state the system is in
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or drop us a line.
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes less than an hour in most kitchens. Somewhere like Henhurst, lanes, gates and parking are worth mentioning in advance.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building to keep disruption down.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, 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.
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
FAQs for Henhurst
Can you come to Henhurst after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can a school canteen extract in Henhurst be done out of term time?
Yes, holiday work suits schools best. Around Henhurst, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you take the used filters away?
Yes. The dirty filters are taken away for cleaning while a clean set goes in.
Who has the legal duty for fire safety?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Do we lose a day’s trading?
Not normally. We need the work area to ourselves while we are on site, so the visit goes in a quiet slot.
How much does a filter exchange service cost?
The cost depends on your filters and the schedule. Just ring 0345 646 2711, or email photos for a fixed quote once we know your canopies.
