Grease filter exchange in Lagness, done properly
Across Lagness, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, whether there’s one canopy or many. Visits can be timed around your service, so cooking isn’t interrupted. The work covers school and hospital kitchens, mesh filters and restaurants and pubs, and common reasons people get in touch are grease filters clogged with grease and hand-washed filters that still look greasy.
In a small place like Lagness, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
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.

Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Keep the canopy clear for exchange visits
- Never leave gaps in the filter bank
- Keep the extract on whenever the range is in use
- Clean the canopy surfaces regularly
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes well under an hour for most canopies. If you can send pictures, we can arrive in Lagness knowing what to expect.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Signs you need grease filter exchange in Lagness
Wherever you are, Lagness included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for filters to fill with grease.
Keep an eye out for any of the following:
- Grease left in baffles after washing
- Filters so greasy the air can barely pass
- Damaged filters letting grease past
- Weak extraction at the canopy
If you run catering at a healthcare site, such as a hospital like Bognor Regis War Memorial Hospital about 2.4 miles east, the extract may need cleaning more often than a part-time kitchen.
What your quote should include
- Whether the quote shows VAT
- Whether a survey comes first
- What records you’ll receive afterwards
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
Why act early in Lagness
When filters block, extraction suffers. The kitchen gets hotter and smokier, and the fan works harder to pull air through. Keeping filters clean keeps the extract working properly. Equipment tucked in a roof space or outbuilding near Lagness rarely gets looked at unless someone books it.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before work begins.

FAQs for Lagness
Who would carry out a food hygiene inspection at a kitchen in Lagness?
That is Arun council, whose environmental health officers carry out food hygiene inspections in Lagness. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you get to a site in Lagness?
Yes. Villages and rural sites across the South East are part of our work, Lagness included. Let us know about access, parking and anything unusual about getting there when you book.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Do you take the used filters away?
We do. Used filters go with us to be cleaned while a clean set goes in.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Which accreditations do you hold?
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.
Is filter exchange enough instead of a full extract clean?
It doesn’t. Filters do not catch everything, so grease still reaches the ductwork and the whole system still needs its TR19 clean.

Food Standards Agency records list about 8 restaurants, cafés and works canteens and about 5 takeaways and sandwich shops across Lagness and its immediate surroundings (about a mile and a half). Swapping filters on a schedule keeps kitchens like these drawing air properly. Kitchens in Lagness get their food hygiene inspections from Arun 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.
