Grease filter exchange in Penn Street
Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. That’s why the whole system still needs cleaning to TR19 at the right interval. If you’re dealing with drips falling from the filters onto equipment and blocked baffle filters, we can put it right, from mesh filters, restaurants and pubs and island canopies onwards.
Somewhere as small as Penn Street, 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.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Leave it or put it right?
In Penn Street, as everywhere, a filter service is not a substitute for TR19 cleaning. They do help keep the system in better shape between cleans and the canopy and plenum stay cleaner. With notice, the visit to Penn Street can be fitted around your bookings and events.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
Why us?
- Work around your opening hours, with 24/7 emergency cover
- Full insurance on every job
- Each visit written up, with pictures
- Accredited under CHAS and SafeContractor, with ISO 9001

Penn Street: your questions answered
Do you work at weekends in Penn Street?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Penn Street needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
Can you clean school kitchen extracts in Penn Street during the holidays?
Yes, out-of-term visits are normal for schools. Around Penn Street, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
How long does grease filter exchange take?
The work itself takes well under an hour for most canopies. Bigger or more complicated systems take longer, and the quote will say how long.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you offer emergency callouts?
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 accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Is Penn Street in your area?
Yes. We cover Penn Street and across Buckinghamshire, as part of our work across South East England and London. For a fixed quote, phone us on 0345 646 2711, or send details by email.
Is TR19 a legal requirement?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
How the visit works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few minutes per canopy, longer for a large kitchen with several canopies. If the van will struggle with a lane or gateway near Penn Street, let us know and we’ll plan around it.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Before we arrive
- Clear the space around the work
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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.
Kitchen extracts in Penn Street
The Food Standards Agency lists about 4 pubs and bars as registered food businesses within about 1.5 miles of central Penn Street. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Penn Street is covered by Buckinghamshire 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. Food hygiene inspections in Penn Street are the job of Buckinghamshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Hughenden Manor is about 4.1 miles west), access may need planning. For schools such as Curzon Church of England Combined School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Aftercare tips
Once we have finished, these simple steps help:
- Keep every filter in place during service
- Keep the canopy clear for exchange visits
- Look out for drips from the canopy
- Book full TR19 cleans alongside filter changes
Fresh filters improve airflow at the canopy right away. Keep the extract running while you cook so the filters do their job.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both means neither slips.

What affects the cost of grease filter exchange
We quote each job individually. This is what makes a difference:
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- Site rules, permits and inductions
- The size of the system
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Any access panels or hatches you can see
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. Once you have those, call us on 0345 646 2711, or email photos.
How the job changes from site to site
Mesh filters
Mesh filters are still found in many canopies. We exchange them on the same basis as baffles.
The plenum
With good filters, less grease ends up in the plenum, but it still needs cleaning as part of TR19.
What we’re called out for in Penn Street
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
Any of these means the system needs a check-up:
- Grease building up behind the canopy filters
- Hand-washed filters that still look greasy
- Gaps where filters have been removed
- A canopy that drips grease
Volunteers running a hall kitchen near Church of the Holy Trinity, or anywhere in Penn Street, may not know when the extract was last cleaned, and a grease test settles it.
What to look for in a quote

- Whether the figure could change on the day
- What happens if part of the system can’t be accessed
- Whether they’re fully insured
