Grease filter exchange for kitchens and businesses in Thornhill
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. The work covers school and hospital kitchens, baffle filters and wall canopies, and people most often call us about a greasy plenum behind the filters and hand-washed filters that still look greasy.
Around a smaller place like Thornhill, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Grease filter exchange around Thornhill
The coast is only about 3 miles from Thornhill. 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 data shows about 18 pubs, bars and clubs registered across Thornhill and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Thornhill get their food hygiene inspections from Southampton council. 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.
Healthcare kitchens, like those at hospitals such as Moorgreen Hospital (about 1.4 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you look after a school kitchen, at a school such as Thornhill Primary School or anywhere near Thornhill, the holidays are the usual time for a TR19® clean.

Different parts, different methods
Canopy filter housings
The filter housing holds each filter at an angle in the canopy. A damaged housing leaves gaps.
The plenum
With good filters, less grease ends up in the plenum, but it still needs cleaning as part of TR19.
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.

Common questions in Thornhill
Which fire service covers Thornhill?
Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Thornhill. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you do school kitchen extract cleaning in Thornhill in the summer holidays?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 29 schools, colleges and universities with registered kitchens within about a mile and a half of Thornhill. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you clean filters as well as exchanging them?
We offer filter cleaning as well as exchange. We will explain the options when you get in touch.
Is filter exchange enough instead of a full extract clean?
No, the two work together. A TR19® clean deals with the whole system and comes with a certificate and photo report.
How regularly do grease filters need exchanging?
It varies from kitchen to kitchen. We look at your cooking and set an interval to match, and adjust it if needed.
Do you handle baffle and mesh filters?
Baffle filters and mesh filters. Tell us what you have when you call us on 0345 646 2711 or email us, or we will check on the first visit.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Never leave gaps in the filter bank
- Keep filter exchange and TR19 cleaning on the same plan
- Do not refit a filter that is bent
- Keep canopy surfaces wiped down
The canopy looks cleaner and the air moves better right away. Keep the extract running while you cook so they catch grease as intended.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
What happens on the day
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. On site, the work takes less than an hour in most kitchens. Tell us about any gates, ladders or locked plant areas at your site near Thornhill when you book.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system

We do not publish a 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 start, call us on 0345 646 2711, or send details by email.
Advice
How we price grease filter exchange
The price is fixed before any work begins. It takes into account:
- What state the system is in
- The size of the system
- Site requirements such as sign-in and permits
- Parking and loading at the site
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
- Any previous report or certificate
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
What we are called out for in Thornhill
Every fry, grill and sauté sends grease-laden vapour upwards. The filters catch much of it so they gradually clog and airflow falls away.
Look out for any of the following:
- Grease dripping from the canopy
- A canopy running with filters missing
- Bent or damaged filters that do not sit properly
- A greasy plenum behind the filters
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (South Stoneham House is about 2.4 miles north-west), access may need planning.
