Part by part

About our grease filter exchange in Stone
In Stone, our filter exchange runs on a schedule set by how much the kitchen cooks. Busy kitchens need changes more often, lighter ones less. The interval is agreed before the first visit. The work covers mesh filters, school and hospital kitchens and wall canopies, and people most often call us about grease left in baffles after washing and missing filters in the filter bank.
Kitchens around a place like Stone are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Your questions about grease filter exchange in Stone
Who is the fire and rescue service for Stone?
Stone is in the area of Kent Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Does the law say we must follow TR19?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.

The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. Because the survey comes first, a visit to Stone can typically be finished without a second trip.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Preparing for the visit
- Agree a time when the area can be out of use
- Clear the space around the work
- Name a contact who can let us in at the agreed time

Advice
Stone kitchens: local notes
Look up Stone on the FSA’s food hygiene register and you’ll find about 74 cafés, restaurants and staff canteens and about 27 sandwich bars and takeaways across Stone and its immediate surroundings (about a mile and a half). Clogged filters slow the airflow, and busy kitchens like these clog them fast. The fire and rescue service for Stone is Kent Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Environmental health officers from Dartford council inspect food businesses in Stone. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
If you run a café or takeaway near Stone Crossing station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Church and community hall kitchens, near Church of St Mary or anywhere around Stone, are easy to forget, but their extracts collect grease like any other.

What affects the cost of grease filter exchange
The survey tells us what the work involves. The main factors are:
- Site requirements such as sign-in and permits
- How big the system is
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Helping us quote
Before you ask for a quote, gather:
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- Wide photos of the system and the area around it
- Where the site is and what kind of site it is
For grease filter exchange in Stone, call us on 0345 646 2711 or email us. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. We usually send a fixed quote within one working day.
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
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’re happy to quote for all of it.
Do you need grease filter exchange in Stone?
Kitchens in Stone, as everywhere, find filter washing slips down the list on busy weeks. It only takes a couple of missed weeks for a filter bank to clog.
It’s time to book a visit if you see:
- Grease collecting in the filter channels
- Filter washing that keeps being missed
- A canopy running with filters missing
- Grease filters clogged with grease
Healthcare kitchens, like those at hospitals such as Darent Valley Hospital (about 1 mile south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
What to look for in a quote
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the price is fixed
- Whether a written report and photos are included
- Whether inaccessible sections are listed on the report
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 readings can rise between cleans. A site near Stone that has to close at short notice is hard to cover for.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
