How we handle grease filter exchange in Thrupp
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. So the canopy, plenum and ducts still need their full TR19 clean. The work covers baffle filters, island canopies and mesh filters, and people most often call us about gaps where filters have been removed and poor airflow through the filters.
In a small place like Thrupp, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Why deal with it now?
For any kitchen in Thrupp, filters cannot stand in for a full TR19 clean. But clean filters do help the system between cleans and the canopy and plenum stay cleaner. It’s simpler to plan the work at Thrupp now than to arrange it in a hurry later.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

How we price grease filter exchange
We quote each job individually. These are the things that affect it:
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- Site rules, permits and inductions
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- When the site is open and when it’s quiet
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Signs you need grease filter exchange in Thrupp
Sometimes a filter is taken out and never put back. A missing filter leaves an open route into the system where it settles out of sight.
Keep an eye out for any of the following:
- Filters so greasy the air can barely pass
- Staff short of time to wash filters
- Poor airflow through the filters
- A greasy plenum behind the filters
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Acland Hospital is the nearest hospital to Thrupp, about 5.7 miles south.

How it works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. The timing of a visit to Thrupp is set by you, and the travel is our side of the planning.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system
- Let us know about parking and loading

Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
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.

Common questions in Thrupp
Who inspects food businesses in Thrupp?
The local authority for Thrupp is Cherwell council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you do school kitchen extract cleaning in Thrupp in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Thrupp, it pays to plan holiday dates ahead. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Do you take the used filters away?
We take them away. That is the point of an exchange: clean filters in, dirty ones out and nothing greasy left on site.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What if some of our filters are damaged?
Damaged filters don’t seat properly and let grease through. We flag any we find so they can be replaced.
Do you handle baffle and mesh filters?
Both baffle filters and mesh filters are covered. At the start, we note what your canopies use so every set we bring fits.
Does a filter exchange disrupt service?
A filter change is quick and can be timed around service. Cooking shouldn’t happen with the filters out so the swap is done promptly.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
