Keyhaven grease filter exchange
A scheduled grease filter exchange, swapping dirty canopy filters for clean ones for businesses, landlords and public buildings in Keyhaven. CHAS, SafeContractor and ISO 9001, and fully insured.
- Filters that leave gaps in the canopy
- Filters so greasy the air can barely pass
- Filters that come out of the sink still dirty
How we handle grease filter exchange in Keyhaven
We set up grease filter exchange for kitchens in Keyhaven on a schedule that suits their cooking. Busy kitchens need changes more often while a lighter kitchen can go longer. The interval is agreed before the first visit. If you’re dealing with smoke and heat lingering under the hood and grease building up behind the canopy filters, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a short visit, depending on how many filters the canopies hold. Pictures of the system and its access let us plan the work in Keyhaven before we set off.
- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- 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.
Preparing for the visit
- Clear the space around the work
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Ask for a quote
Some systems can be priced from pictures; others need a survey. 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.
Advice
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What affects the cost of grease filter exchange
You’ll get a fixed price before we start. It’s based on:
- Whether several sites go on one quote
- Site rules, permits and inductions
- What state the system is in
- Where the site is and how we reach it
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 give you a fixed price before we start.
Helping us quote
To speed up the quote, send us:
- Wide pictures of the system and the area around it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Any access panels or hatches you can see
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To get going, call 0345 646 2711 or drop us a line.
Grease filter exchange in Keyhaven: the local picture
Keyhaven is within about 1 mile 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. Food Standards Agency records list about 16 restaurants, cafés and canteens in Keyhaven and the streets around it, up to about 1.5 miles out. Each canopy among them has filters that load with grease and need swapping or cleaning. Keyhaven is covered by Hampshire and Isle of Wight Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in Keyhaven, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Lymington New Forest Hospital about 3.4 miles north, the extract may need cleaning more often than a part-time kitchen.
Keyhaven is about 3 miles south of Lymington, in Hampshire. Whether your site is in the middle of Keyhaven or further out, grease filter exchange is available to all kinds of commercial premises, from a single unit to a large public building.

What we’re called out for in Keyhaven
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking, so the right exchange interval varies.
Clients normally contact us after spotting something like this:
- Grease dripping from the canopy
- Missing filters in the filter bank
- Grease left in baffles after washing
- Bent or damaged filters that don’t sit properly
For schools such as Milford-on-Sea Church of England Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
What your quote should include
- Whether the quote shows VAT
- When the next visit should be, and why
- What hours they’ll be on site
- What records you will receive afterwards
Aftercare tips
Once we’ve finished, these simple steps help:
- Never leave gaps in the filter bank
- Clear anything stored on or near the canopy
- Do not let the full clean slip because filters are changed
- Look out for drips from the canopy
The canopy looks cleaner and the air moves better from the moment they’re fitted. Keep the extract running while you cook so they catch grease as intended.
Filter exchange and TR19 cleaning work best together. A maintenance plan that covers both means neither slips.
Keyhaven: your questions answered
Can you get to a site in Keyhaven?
Yes, Keyhaven is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Which fire authority looks after Keyhaven?
Keyhaven is in the area of Hampshire and Isle of Wight Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
How much does a filter exchange service cost?
We price it on the number of filters and the visit frequency. Tell us what you have and we’ll come back with a fixed quote, normally within one working day.
Do we need to close the kitchen while filters are changed?
Most changes take anything from a few minutes to an hour or so, depending on the number of filters, so the impact is small. We plan visits outside your busiest times wherever we can.
How long will you be on site?
Your quote will say how long we expect to be there. For a typical site, it takes a few minutes per canopy, longer for a large kitchen with several canopies.
Can damaged filters stay in the canopy?
Damaged filters do not seat properly and let grease through. We point them out on the visit so they can be replaced.
Does a filter exchange replace TR19 cleaning?
It does not. Some grease passes the filters as vapour and settles in the ducts, so the full system still needs cleaning to TR19.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What the work involves, part by part
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.
Canopy filter housings
Filters sit in a housing or channel in the canopy. If it’s bent or greasy, filters will not seat properly.
