Grease filter exchange in Northwood
Think of filter exchange as routine care for the extract. 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. If you are dealing with grease collecting in the filter channels and a canopy that drips grease, we can help.
In a village or hamlet like Northwood, 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.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Northwood
Washing filters by hand does not always get them clean. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
Clients usually contact us after spotting something like this:
- Filters so greasy the air can barely pass
- Staff short of time to wash filters
- Grease left in baffles after washing
- Poor airflow through the filters
Where a hall near All Saints' Church, or anywhere in Northwood, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before booking anyone
- What happens if part of the system cannot be accessed
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
- What hours they’ll be on site
Between visits
Aftercare is simple, and it makes the next visit easier:
- Keep filter exchange and TR19 cleaning on the same plan
- Tell us if a filter is bent or damaged
- Clean the canopy surfaces regularly
- Make sure we can reach the canopy on exchange day
The canopy looks cleaner and the air moves better straight away. Always run the extract during cooking so the filters do their job.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
Why act early in Northwood
Clogged filters choke the extract. Heat and fumes hang in the kitchen while the fan strains. A regular exchange keeps the airflow where it should be. Somewhere as small as Northwood, losing a kitchen or building to a fault is felt by everyone who uses it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

What affects the cost of grease filter exchange
There’s no set price list, because no two systems are the same. The quote depends on:
- What state the system is in
- The scale of the work
- One-off work versus a regular cycle
- Whether several sites go on one quote
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.
Helping us quote
You do not need the technical terms. It helps if you can send:
- The times we could work without disrupting the site
- The site address and the type of premises
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room

What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes a short visit, depending on how many filters the canopies hold. A quick note on how to find the site and where to park makes a visit to Northwood run smoothly.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Preparing for the visit
- Tell us where we can park and unload
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
Ask for a quote
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Related advice
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What the work involves, part by part
The plenum
With good filters, less grease ends up in the plenum, but it’s still cleaned during a full TR19 clean.
Mesh filters
Mesh filters use layers of metal mesh to trap grease. They clog quickly in a busy kitchen, so they need changing often.

Northwood questions
Can school kitchens in Northwood be cleaned in the holidays?
Yes, and it’s the easiest time to do it. There are about 6 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Northwood. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Who would carry out a food hygiene inspection at a kitchen in Northwood?
In Northwood, it’s Isle of Wight council that carries out food hygiene inspections. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How long will you be on site?
We’ll confirm the time with your quote. For a typical site, it takes well under an hour for most canopies.
Grease filter exchange in Northwood: the local picture
Northwood is within about 2 miles of the coast. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. The FSA’s food hygiene register includes about 20 pubs and bars and about 8 hotels, B&Bs and guest houses within about 1.5 miles of central Northwood. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Northwood sits within the area of Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If your kitchen is in a listed or historic building, like the houses around Northwood (Osborne House is about 2 miles east), fitting access panels needs care. Term dates shape school work: for a school like Northwood Primary School, an extract clean fits neatly into a half-term or summer break.
