Grease Filter Exchange in Greatham
For grease filter exchange in Greatham, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Bent or damaged filters that do not sit properly
- Blocked baffle filters
- Filter washing that keeps being missed
Between visits
How long the results last depends on use and care. We suggest:
- Clean the canopy surfaces regularly
- Tell us if a filter is bent or damaged
- Never cook with the extract switched off
- Mention it if the kitchen gets busier
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward, and we can arrange it.
A kitchen that is getting busier needs its filters changed more often. Changing the interval early stops grease building up unseen behind the canopy.
Grease filter exchange in Greatham
Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum and every filter is checked when we swap them. We point out any that need replacing. The work covers island canopies, mesh filters and restaurants and pubs, and the jobs we see most are drips falling from the filters onto equipment and grease left in baffles after washing.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Duct Doctor has been trading since 2009, as 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.

Why it’s worth doing now in Greatham
Dripping canopies and greasy smells often start with the filters. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. A planned visit to Greatham is easier to arrange than an emergency callout.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.

Greatham kitchens: local notes
The fire and rescue service for Greatham is Hampshire and Isle of Wight Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Greatham are the job of East Hampshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you look after a school kitchen, at a school such as Greatham Primary School or anywhere near Greatham, the holidays are the usual time for a TR19® clean. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Chase Community Hospital is the nearest hospital to Greatham, about 2.5 miles north-east.

What we’re called out for in Greatham
Long cooking hours in Greatham or anywhere else mean more grease on the filters. Heavy daily use means fast build-up, so it needs more frequent changes.
Keep an eye out for these warning signs:
- Gaps where filters have been removed
- Drips falling from the filters onto equipment
- Bent or damaged filters that do not sit properly
- Grease filters clogged with grease
Where a hall near Church of St John the Baptist, or anywhere in Greatham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before you book
- Whether the work can be done while the site is closed

- Whether the quote is based on a survey or pictures
- Proof of accreditation you can verify
In-house cleaning or a specialist?
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Different parts, different methods
The plenum
Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease drops out as it does.
FAQs for Greatham
Is Greatham within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Who carries out food hygiene inspections in Greatham?
Food hygiene inspections in Greatham are carried out by East Hampshire council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can damaged filters stay in the canopy?
We check every filter at each visit. Any that are bent or damaged are flagged, because gaps let grease into the plenum.
What types of filter do you exchange?
We work with both baffle and mesh filters. The first step is recording what you have and set up the service around them.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Will we have to stop cooking for a filter change?
Visits are short, and can be booked outside service times. There’s no wait between removing and refitting.
How much does a filter exchange service cost?
It depends on the number and type of filters and how often they’re changed. We will send you a fixed quote once we know your canopies.
How it works
Each visit runs to the same pattern: protect the area, make the system safe, do the work, tidy up and leave you the report. The visit itself takes anything from a few minutes to an hour or so, depending on the number of filters. In a small place like Greatham, the journey is planned ahead and the visit arranged around the site’s hours.
- We start by noting how many filters you have and what type they are.
- We agree a schedule that suits how much the kitchen cooks.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading

Getting a quote doesn’t take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
