Grease filter exchange in Charlwood, done properly
Think of filter exchange as routine care for the extract. It keeps airflow up and grease down between full cleans and takes a messy task off your team. The full TR19 clean then gives the system its clean bill of health. The work covers wall canopies, island canopies and baffle filters, and the jobs we see most are a canopy running with filters missing and filters left unwashed on busy weeks.
Work in a small place like Charlwood starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What grease filter exchange looks like in Charlwood
Fire safety in Charlwood falls to Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. At about 50 miles from central London, Charlwood sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
Church and community hall kitchens, near Monkwood Mission Church or anywhere around Charlwood, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Charlwood is Alton Community Hospital, about 4.7 miles north-east. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Bentworth Hall is about 4.8 miles north), access may need planning.
Charlwood is about 6 miles south-west of Alton, in Hampshire. Sites in Charlwood get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures.

FAQs for Charlwood
Which fire and rescue service is responsible for Charlwood?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Charlwood. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Which environmental health team covers Charlwood?
In Charlwood, it’s East Hampshire council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you recommend a next date?
Yes. The interval depends on how much the system is used and what we find, and we explain the reasoning on the report.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a written, dated record with pictures of what we did and anything we couldn’t access.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
What types of filter do you exchange?
Baffle filters and mesh filters. Mention how many canopies you have when you get in touch, or we will check on the first visit.
Is there a cleaning option for the filters we have?
Yes, filter cleaning is available. The first step is looking at the filters you have, as damaged ones may be better replaced.
Part by part
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is usually the tightest.
Canopy filter housings
The trough or channel under the filters fills with grease. We point it out if it needs cleaning.
What happens if it’s left?
Leaving filters too long pushes more grease into the plenum and ducts. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. Equipment tucked in a roof space or outbuilding near Charlwood rarely gets looked at unless someone books it.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.

When it’s something else
Not every problem is solved by grease filter exchange, and we’ll tell you before we start. It doesn’t solve:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Extraction problems caused by the fan rather than the filters
- A canopy too small for the cooking beneath it
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly before booking.
Where we work
- Island canopies
- Baffle filters
- Wall canopies
- Restaurants and pubs
- Mesh filters
- School and hospital kitchens
Looking after it afterwards
After the visit, a few habits help the work last:
- Let us know if your cooking hours increase
- Do not refit a filter that is bent
- Always run the extract while cooking
- Book full TR19 cleans alongside filter changes
Once the clean filters are in, the kitchen can cook right away. The dirty set leaves with us to be cleaned.
A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up in the ducts.
How we price grease filter exchange
The price is fixed before any work begins. It takes into account:
- How easy every part is to reach
- Parking and loading at the site
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.
What we need to know
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Problems your staff have spotted
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a few minutes per canopy, longer for a large kitchen with several canopies, and the area is cleaned down before we leave. A few pictures of the system help us make the most of a visit to a place like Charlwood.
- We look at the canopies and the condition of the filters.
- 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.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Have your last certificate or report to hand
