What affects the cost of grease filter exchange
Your quote is based on your site. We consider:
- What state the system is in
- How big the system is
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Problems your staff have spotted
- Wide photos of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
How we handle grease filter exchange in Bell's Corner
Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. The work covers wall canopies, baffle filters and mesh filters, and common reasons people get in touch are filters that leave gaps in the canopy and a greasy plenum behind the filters.
In a small place like Bell's Corner, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, and we are 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.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Keep the extract on whenever the range is in use
- Book full TR19 cleans alongside filter changes
- Tell us if the menu or opening hours change
- Make sure we can reach the canopy on exchange day
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward and we can book that in.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Common questions in Bell's Corner
Will you come out to Bell's Corner?
Yes. Villages and rural sites across the South East are part of our work, Bell's Corner included. The journey is planned ahead, so a few details about the route help.
Can the work in Bell's Corner be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Bell's Corner can fit around your hours. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Do you provide a certificate or report?
Yes. You get a written report with photos after every visit, showing what was done, anything we couldn’t reach and when the next visit is due. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Does a filter exchange replace TR19 cleaning?
It doesn’t. Some grease passes the filters as vapour and settles in the ducts and the whole system still needs its TR19 clean.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
What accreditations do you have?
Our accreditations are 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.
Is there a cleaning option for the filters we have?
Yes, filters can be cleaned on a schedule as well as exchanged. We will explain the options when you get in touch.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Different parts, different methods
Mesh filters
Mesh traps grease between its layers, so a quick rinse rarely gets it clean.
Canopy filter housings
We check that filters sit snugly in the housing at each visit, because gaps let grease through.
Grease filter exchange in Bell's Corner: the local picture
Bell's Corner is about 55 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. Bell's Corner sits within the area of Essex County Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Bursars and site managers at schools such as Stoke-by-Nayland Church of England Primary School tend to book extract cleaning for when the kitchen is empty. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Bell's Corner is Severalls Hospital, about 5.8 miles south.

Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Bell's Corner, the date and timings are agreed with you well before the day.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Getting ready for the visit
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards

Related advice
What we are called out for in Bell's Corner
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up, so it needs more frequent changes.
It’s time to book a visit if you see:
- Grease building up behind the canopy filters
- A canopy running with filters missing
- Smoke and heat lingering under the hood
- Filter washing that keeps being missed
Where a hall near Church of St Mary, or anywhere in Bell's Corner, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before booking
- What happens if part of the system can’t be accessed
- What records you’ll receive afterwards
- What insurance they carry
- Exactly which parts of the system are covered
