Grease filter exchange in Heronsgate, done properly
We set up grease filter exchange for kitchens in Heronsgate 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 restaurants and pubs, school and hospital kitchens and wall canopies, and common reasons people get in touch are a canopy that drips grease and grease collecting in the filter channels.
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.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What happens if it’s left?
Grease dripping from the canopy is a sign the filters can’t hold any more. Drips land on surfaces and equipment below, which an EHO may well notice. Somewhere as small as Heronsgate, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
What you get with us
- One contact for all your sites in London and the South East
- Fully insured
- Work around your opening hours, with 24/7 emergency cover
- Photo reports with every job
What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes less than an hour in most kitchens. We agree a date with you, plan the drive to Heronsgate and turn up when the site is quiet.
- We start by noting how many filters you have and what type they are.
- Together we set how often the filters should be changed.
- At every visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload

Advice
What the work involves, part by part
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is typically the tightest.
Canopy filter housings
The trough or channel under the filters fills with grease. We point it out if it needs cleaning.
Common questions in Heronsgate
Which fire authority looks after Heronsgate?
Fire safety enforcement in Heronsgate is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can a school canteen extract in Heronsgate be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. There are about 16 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Heronsgate. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we will fit the work in.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
What happens to the dirty filters?
They leave with us. That’s the point of an exchange: clean filters in, dirty ones out, with no washing for your team.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.
What does grease filter exchange cost?
We price it on the number of filters and the visit frequency. Tell us what you have and we’ll come back with a fixed quote, normally within one working day.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
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.
When it’s something else
We’d rather tell you now than book work that won’t help, so here are the limits:
- Extraction problems caused by the fan rather than the filters
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Cooking smells reaching neighbours, which need odour control
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly.
What the work covers
- Mesh filters
- Island canopies
- School and hospital kitchens
- Wall canopies
- Restaurants and pubs
- Baffle filters
Do you need grease filter exchange in Heronsgate?
Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum where it settles out of sight.
Keep an eye out for any of the following:
- Drips falling from the filters onto equipment
- Filters that leave gaps in the canopy
- Poor airflow through the filters
- Hand-washed filters that still look greasy
For schools such as Chorleywood Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
What to look for in a quote
- Proof of accreditation you can verify
- How areas they can’t reach will be recorded
- Whether they recommend a next date
- Whether the whole system is included, or only the parts that are easy to reach
Grease, kitchens and Heronsgate
The FSA’s food hygiene register shows about 27 restaurants, cafés and canteens and about 6 takeaways across Heronsgate and its immediate surroundings (about a mile and a half). Clogged filters slow the airflow, and busy kitchens like these clog them fast. Heronsgate sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Heronsgate are the job of Three Rivers council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run catering at a historic house or estate in the area (Chenies Manor House is about 2.4 miles north), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens, like those at hospitals such as Harefield Hospital (about 2.8 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Heronsgate is about 1 mile south-west of Chorleywood, in Hertfordshire. From the centre of Heronsgate to the outskirts, we cover grease filter exchange for every kind of premises, from a single unit to a large public building.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
