Grease filter exchange in New Marston, done properly
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. We are often asked to deal with a greasy plenum behind the filters and drips falling from the filters onto equipment, on wall canopies, school and hospital kitchens and mesh filters.
Kitchens around a place like New Marston are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
We have 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’re fully insured.

What the work involves, part by part
School, care home and staff kitchens
Visits can be planned around holidays and quieter periods so the filters are clean when cooking picks up.
Mesh filters
Mesh traps grease between its layers, so a quick rinse rarely gets it clean.
What happens on the day
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes well under an hour for most canopies, and we clear up before we go. Around New Marston, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- 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
- Have your last certificate or report to hand
- Clear loose items from the work area
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Tell us if a filter is bent or damaged
- Watch for grease drips between visits
- Tell us if the menu or opening hours change
- Do not let the full clean slip because filters are changed
The canopy looks cleaner and the air moves better from the moment they’re fitted. Keep the extract running while you cook so they catch grease as intended.
Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.
Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Grease filter exchange around New Marston
Food Standards Agency data counts about 341 restaurants, cafés and works canteens and about 34 sandwich bars and takeaways within roughly a mile and a half of the centre of New Marston. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. In New Marston, food businesses are inspected by environmental health officers from Oxford City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in New Marston falls to Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Holywell Manor, about 0.7 miles south-west, is one of the historic houses near New Marston; if you run event catering at a venue like that, cleans can be booked between functions.

Questions from New Marston
Which fire authority looks after New Marston?
Oxfordshire Fire and Rescue Service is the fire and rescue service for New Marston. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Will you come out to New Marston?
Yes, New Marston is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Do you handle baffle and mesh filters?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so every set we bring fits.
Do you deal with bent or broken filters?
A badly damaged filter should be replaced. We’ll show you which ones on the visit.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do I get a report after the visit?
Yes, on every job. It’s a dated, written report with photos, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.
Does a filter exchange replace TR19 cleaning?
It is not. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Facilities teams in offices, schools and healthcare sites book us too across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.
What grease filter exchange cannot fix
Before you book, it helps to know what’s not included:
- Smell complaints that need odour control equipment
- Extraction problems caused by the fan rather than the filters
- A heavily greased plenum or canopy, which needs cleaning to TR19
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think.
Where we work

Common problems we fix in New Marston
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters so they gradually clog and airflow falls away.
The symptoms we are asked about most are:
- Hand-washed filters that still look greasy
- Weak extraction at the canopy
- A greasy plenum behind the filters
- Bent or damaged filters that do not sit properly
A hospital like Churchill Hospital, about 0.7 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
