About our grease filter exchange in Marston
A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. The work covers mesh filters, school and hospital kitchens and island canopies, and people most often call us about weak extraction at the canopy and filter washing that keeps being missed.
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. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Part by part
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease drops out as it does.
Mesh filters
Older or smaller canopies often use mesh filters. They can be on the same exchange schedule as baffle filters.

Common questions in Marston
Which council inspects kitchens in Marston?
Kitchens in Marston are inspected by Oxford City council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Which fire service covers Marston?
Fire safety enforcement in Marston is handled by Oxfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Can you give a price for filter changes?
It depends on the number and type of filters and how often they’re changed. Just ring 0345 646 2711, or email photos for a fixed quote once we know your canopies.
How long does grease filter exchange take?
That depends on how much there is to do, but for many sites it takes a few minutes per canopy, longer for a large kitchen with several canopies. We’ll confirm it with the quote.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
What types of filter do you exchange?
Both baffle filters and mesh filters are covered. We record the sizes and number of filters at the start so the clean set always fits.
What affects the quote in Marston
The diagnosis comes before the price. The main factors are:
- How easy every part is to reach
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
- The times the site is available
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Honest limits
A few issues sit outside what this work can do:
- An extract that was undersized from the start
- Odours from the discharge that filters won’t stop
- A noisy or failed extract fan
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think before booking.

Managing agents and facilities teams in Marston
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few minutes per canopy, longer for a large kitchen with several canopies. Somewhere like Marston, lanes, gates and parking are worth mentioning in advance.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
Getting a quote
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or email us.

Why act early in Marston
Grease dripping from the canopy is a sign the filters cannot hold any more. Drips land on surfaces and equipment below, which an EHO may well notice. Planning a trip to Marston ahead is easier for everyone than a rushed one.

Grease filter exchange around Marston
The Food Standards Agency lists about 20 pubs, bars and clubs and about 8 hotels and guest houses as registered food businesses within roughly a mile and a half of the centre of Marston. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Oxfordshire Fire and Rescue Service covers Marston. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Marston get their food hygiene inspections from Oxford City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Churchill Hospital is the nearest hospital to Marston, about 1.2 miles south-east. Where a hall near Church of St Nicholas, or anywhere in Marston, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like St Nicholas Primary School, an extract clean fits neatly into a half-term or summer break.
