Grease filter exchange in Bockmer End, done properly
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. That’s why the whole system still needs cleaning to TR19 at the right interval. The work covers school and hospital kitchens, mesh filters and restaurants and pubs, and people most often call us about blocked baffle filters and damaged filters letting grease past.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What we are called out for in Bockmer End
Cooking vapour carries grease into the canopy. The filters catch much of it, and day by day they load up and airflow falls away.
Look out for these warning signs:
- Filters left unwashed on busy weeks
- Filters that come out of the sink still dirty
- A canopy that drips grease
- Gaps where filters have been removed
A hospital like Marlow Community Hospital, about 2.7 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Before you book anyone
- Whether the whole system is included, or only the parts that are easy to reach
- What records you’ll receive afterwards
- Whether the work can be done while the site is closed
- Whether they’re fully insured
What affects the cost of grease filter exchange
The diagnosis comes before the price. The main factors are:
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
When you contact us, it’s useful to have:
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Need a price for grease filter exchange? Please give us a ring on 0345 646 2711 or send us an email with a few details about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Visits to a village like Bockmer End are booked in advance, at a time that suits whoever runs the site.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
- Mention any parking or loading restrictions
Get a fixed quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare in Bockmer End and across Buckinghamshire. Larger estates can be phased building by building to keep disruption down.
Leave it or put it right?
For any kitchen in Bockmer End, filters can’t stand in for a full TR19 clean. They do help keep the system in better shape between cleans and the canopy and plenum stay cleaner. Equipment tucked in a roof space or outbuilding near Bockmer End rarely gets looked at unless someone books it.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

Your questions about grease filter exchange in Bockmer End
Can you work in Bockmer End outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Bockmer End does not have to lose a day’s trading. When you ring 0345 646 2711 or drop us a line, mention when the site is quiet.
