Grease filter exchange for kitchens and businesses in Old Knebworth
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. We’re often asked to deal with a canopy that drips grease and missing filters in the filter bank, across baffle filters, wall canopies and restaurants and pubs.
In a small place like Old Knebworth, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
To keep the system working properly between visits:
- Keep the canopy clear for exchange visits
- Always run the extract while cooking
- Report a dripping canopy early
- Never leave gaps in the filter bank
The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too.

Advice
How we price grease filter exchange
A fixed price needs a few facts first. We check:
- How many systems or sites are involved
- Site requirements such as sign-in and permits
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
To help us quote quickly, please include:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
To get a fixed quote, call us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Different parts, different methods
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota so the filters are clean when cooking picks up.
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They do not clean themselves, because the grease they collect builds up.
Questions from Old Knebworth
Do you work at weekends in Old Knebworth?
Yes, we can come after you close and finish before you open. The work in Old Knebworth can fit around your hours. Let us know the hours you are closed and we will book within them.
Who carries out food hygiene inspections in Old Knebworth?
Food hygiene inspections in Old Knebworth are carried out by North Hertfordshire council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you give a price for filter changes?
Pricing depends on the kitchen, so we quote once we know your filters and schedule. You get a fixed price before the first visit.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.
How long does grease filter exchange take?
The work itself takes anything from a few minutes to an hour or so, depending on the number of filters. Bigger or more complicated systems take longer, and the quote will say how long.
Which grease filters does the service cover?
Baffle and mesh filters are both covered. The first step is recording what you have and plan the exchange around them.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Common problems we fix in Old Knebworth
Repeated removal and washing takes its toll on filters. A bent filter doesn’t seat properly and grease passes round them.
It’s time to book a visit if you see:
- Filters that leave gaps in the canopy
- Grease left in baffles after washing
- Weak extraction at the canopy
- Grease collecting in the filter channels
If you run catering at a historic house or estate in the area (Knebworth House is about 0.2 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
