Grease filter exchange in Wherwell Wood
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. That is why the whole system still needs cleaning to TR19 at the right interval. If you have grease building up behind the canopy filters and filters that leave gaps in the canopy, we can help.
In a small place like Wherwell Wood, 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.
Duct Doctor has 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 carry full insurance.

Grease, kitchens and Wherwell Wood
The FSA’s food hygiene register includes about 4 pubs and bars within roughly a mile and a half of the centre of Wherwell Wood. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Food hygiene inspections in Wherwell Wood are the job of Test Valley council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Wherwell Wood is Hampshire and Isle of Wight Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
A hospital like Andover War Memorial Hospital, about 3.2 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. For schools such as Wherwell Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

Questions from Wherwell Wood
Which fire service covers Wherwell Wood?
Wherwell Wood is in the area of Hampshire and Isle of Wight Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Which environmental health team covers Wherwell Wood?
In Wherwell Wood, it’s Test Valley council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them where they can be found quickly.
Do you deal with bent or broken filters?
A bent filter leaves a gap for grease. We flag any we find so they can be replaced.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.

Looking after it afterwards
Once we’ve finished, these simple steps help:
- Keep the canopy clear for exchange visits
- Always run the extract while cooking
- Let us know if your cooking hours increase
- Report a dripping canopy early
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due and we can book that in.
A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up behind the canopy.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What we’re called out for in Wherwell Wood
Every fry, grill and sauté sends grease-laden vapour upwards. Much of it is trapped by the filters, and day by day they load up until the air can barely get through.
Keep an eye out for these warning signs:
- Damaged filters letting grease past
- Grease building up behind the canopy filters
- Filters that come out of the sink still dirty
- Missing filters in the filter bank
A hall kitchen that only cooks for events, whether near Church of St Peter or elsewhere in Wherwell Wood, still needs its extract cleaned, just less often.
Questions to ask before you book
- Which accreditations they hold, and whether you can check them
- Exactly which parts of the system are covered
- Whether they recommend a next date
- Whether the quote shows VAT
What the work involves, part by part
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters though usually at a gentler pace.
Canopy filter housings
The trough or channel under the filters fills with grease. We point it out if it needs cleaning.
Why deal with it now?
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Keeping filters clean takes some of that fuel away. Rural sites can’t always move to another kitchen or room when something fails.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

How the visit works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes less than an hour in most kitchens. Somewhere like Wherwell Wood, lanes, gates and parking are worth mentioning in advance.
- 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.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Before we arrive
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
- Have your last certificate or report to hand
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
