Grease filter exchange in Furnace Green, done properly
Cleaning filters by hand takes staff time and is easy to put off. An exchange service means clean filters arrive and greasy ones leave and the canopy is refilled straight away. Common call-outs are for a greasy plenum behind the filters and missing filters in the filter bank, on island canopies, mesh filters and baffle filters.
Size doesn’t change the work: a kitchen in a place like Furnace Green gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes anything from a few minutes to an hour or so, depending on the number of filters. For a place like Furnace Green, we load the van from the survey notes so the work can be done in one visit where possible.
- 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.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
How to prepare
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Let us know about parking and loading

Why it’s worth doing now in Furnace Green
For any kitchen in Furnace Green, filters can’t stand in for a full TR19 clean. But clean filters do help the system between cleans and the canopy and plenum stay cleaner. A visit arranged in advance is far less disruptive than a callout on a busy day.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

How the job changes from site to site
Busy restaurant and pub kitchens
In a busy kitchen, filter washing is easy to skip. A regular exchange means nobody has to remember.
Baffle filters
When baffles fill with grease, less air gets through. Swapping them for a clean set restores it.
When to call us in Furnace Green
Filters get bent and damaged with handling. A bent filter does not seat properly, leaving gaps for grease to slip through.
Look out for any of the following:
- Drips falling from the filters onto equipment
- Grease filters clogged with grease
- Grease building up behind the canopy filters
- Bent or damaged filters that do not sit properly
If you run a church or community hall kitchen, near St Andrew's Church or elsewhere in Furnace Green, its extract still collects grease from every lunch and event.
Questions to ask before you book
- Whether the quote is based on a survey or pictures
- Whether the price is fixed
- What’s included in the scope, part by part
- Proof of insurance
How we price grease filter exchange
Some jobs are bigger than they look, and some smaller. The main factors:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- 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.
Asking for a quote
We can often survey from pictures. Try to include:
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- When the site is open and when it’s quiet
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Common questions in Furnace Green
Can you work in Furnace Green outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Furnace Green can fit around your hours. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Do you do school kitchen extract cleaning in Furnace Green in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Furnace Green, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you take the used filters away?
We take them away. That’s how an exchange works: you always have a clean set fitted and nothing greasy left on site.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Is Furnace Green in your area?
Yes. We cover Furnace Green and the rest of West Sussex, as part of our work across South East England and London. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form.
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 we need to close while you work?
Not typically. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Never leave gaps in the filter bank
- Mention it if the kitchen gets busier
- Never cook with the extract switched off
- Book full TR19 cleans alongside filter changes
The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to match.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both keeps everything on track.
