Grease filter exchange in Oakhanger
A clean set of filters is a simple, regular dose of prevention. It keeps airflow up and grease down between full cleans and takes a messy task off your team. Full TR19 cleaning still comes at the right interval, with a certificate. We’re often asked to deal with a greasy plenum behind the filters and damaged filters letting grease past, across mesh filters, island canopies and restaurants and pubs.
For a kitchen in or near Oakhanger, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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 carry full insurance.

What grease filter exchange looks like in Oakhanger
According to Food Standards Agency records, there are about 3 pubs, bars and clubs in Oakhanger and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Hampshire and Isle of Wight Fire and Rescue Service covers Oakhanger. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Oakhanger get their food hygiene inspections from East Hampshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
A hall kitchen that only cooks for events, whether near St Mary Magdalene's Church or elsewhere in Oakhanger, still needs its extract cleaned, just less often. Term dates shape school work: for a school like Mill Chase Academy, an extract clean fits neatly into a half-term or summer break.

What else we do in Oakhanger
Why deal with it now?
Some kitchens in Oakhanger wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. When it doesn’t happen reliably, an exchange makes it automatic. Systems in rural buildings are often out of sight and out of mind.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What you get with us
- Trading since 2009
- Out-of-hours work and a 24/7 emergency line
- One number for every site across the South East and London
- Survey first, then a fixed quote

Managing agents and facilities teams in Oakhanger
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Oakhanger: your questions answered
Which environmental health team covers Oakhanger?
That is East Hampshire council, whose environmental health officers carry out food hygiene inspections in Oakhanger. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire service covers Oakhanger?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Oakhanger. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Is Oakhanger in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Oakhanger.
Do you recommend a next date?
Yes. How often depends on use and condition and the report sets out why.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
How long does grease filter exchange take?
The work itself takes well under an hour for most canopies. Bigger or more complicated systems take longer, and the quote will say how long.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Do you deal with bent or broken filters?
Filters that no longer fit properly need replacing. We will show you which ones when we find them.
What the work involves, part by part
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters, though often more slowly.
Baffle filters
A clogged baffle filter restricts airflow. Swapping them for a clean set restores it.
Do you need grease filter exchange in Oakhanger?
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
Signs it’s time to call us include:
- Grease filters clogged with grease
- Grease left in baffles after washing
- Poor airflow through the filters
- A canopy that drips grease
Healthcare kitchens, like those at hospitals such as Chase Community Hospital (about 1.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Keep the extract on whenever the range is in use
- Make sure we can reach the canopy on exchange day
- Keep filter exchange and TR19 cleaning on the same plan
- Keep canopy surfaces wiped down
There’s no waiting: the canopy is ready as soon as the clean set is fitted. The dirty set leaves with us for cleaning.
Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both means neither slips.
How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes well under an hour for most canopies. A quick note on how to find the site and where to park makes a visit to Oakhanger run smoothly.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- At each visit, the greasy filters are lifted out.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

When it’s something else
In fairness, some problems need a different fix:
- A canopy too small for the cooking beneath it
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Smell complaints that need odour control equipment
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly before booking.
