About our grease filter exchange in South Wonston
An exchange visit in South Wonston does not take long. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. Anything that needs attention is pointed out. If you are dealing with damaged filters letting grease past and smoke and heat lingering under the hood, we can put it right, from restaurants and pubs, island canopies and baffle filters onwards.
In a village or hamlet like South Wonston, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Signs you need grease filter exchange in South Wonston
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.
It’s time to book a visit if you see:
- Grease filters clogged with grease
- Filters left unwashed on busy weeks
- Filters that come out of the sink still dirty
- A greasy plenum behind the filters
A hall kitchen that only cooks for events, whether near St Margaret's or elsewhere in South Wonston, still needs its extract cleaned, just less often.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
What happens if it’s left?
For any kitchen in South Wonston, filters cannot 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. A fault that closes a site in a village like South Wonston affects everyone who depends on it.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Wipe the outside of the canopy as part of daily cleaning
- Report damaged filters so they can be replaced
- Keep the extract on whenever the range is in use
- Keep filter exchange and TR19 cleaning on the same plan
Once the clean filters are in, the kitchen can cook straight away. We take the greasy filters with us for cleaning.
Dripping filters are a clear sign they’re full. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes well under an hour for most canopies. Rural roads and tight entrances are worth telling us about before a visit to South Wonston.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site

How we price grease filter exchange
A fixed price needs a few facts first. We check:
- Whether we need access equipment or extra panels
- Parking and loading at the site
- The size of the system
- Working hours and out-of-hours timing
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
FAQs for South Wonston
Can you come to South Wonston after we close?
Yes, we can come after you close and finish before you open. The work in South Wonston can fit around your hours. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Which environmental health team covers South Wonston?
That’s Winchester City council, whose environmental health officers carry out food hygiene inspections in South Wonston. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you take the used filters away?
We take them away. That is the point of an exchange: clean filters in, dirty ones out and nothing greasy left on site.
How much does a filter exchange service cost?
It depends on the number and type of filters and how often they’re changed. We’ll send you a fixed quote once we know your canopies.
Which grease filters does the service cover?
We exchange baffle and mesh filters. We record the sizes and number of filters at the start so the clean set always fits.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
What about areas you can’t get to?
We record them on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
