What affects the cost of grease filter exchange
Before we fix a price, we need to know a few things. We check:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- What state the system is in
- The size of the system
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
What we need to know
When you call or email, these details help:
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- The site address and the type of premises
- Wide pictures of the system and the area around it
Getting a quote does not take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
How we handle grease filter exchange in Flamstead
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. If you are dealing with grease left in baffles after washing and damaged filters letting grease past, we can put it right, from baffle filters, mesh filters and wall canopies onwards.
Somewhere as small as Flamstead, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Flamstead questions
Who carries out food hygiene inspections in Flamstead?
The local authority for Flamstead is Dacorum council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you cover smaller places like Flamstead?
Yes. Flamstead is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
How often should grease filters be changed?
The right interval depends on the kitchen. If filters clog early, the interval needs shortening and we will adjust it.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Is filter exchange enough instead of a full extract clean?
No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
Why act early in Flamstead
Changing filters on schedule costs far less disruption than a blocked extract. Few maintenance jobs are as easy, and one of the easiest to let slip. Rural sites cannot always move to another kitchen or room when something fails.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before we start.

What grease filter exchange cannot fix
Grease filter exchange cannot fix everything, and we’d rather say so up front. It does not solve:
- A fan that’s failing or too weak for the system
- A canopy that does not capture the vapour properly
- Grease already built up in the ductwork, which needs a full TR19 clean
If you’re not sure, just call 0345 646 2711 or use the quote form and we will give you a straight answer before booking.

How the job changes from site to site
Busy restaurant and pub kitchens
In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. On site, it takes less than an hour in most kitchens. Visits to a village like Flamstead are booked in advance, at a time that suits whoever runs the site.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Aftercare tips
So the system stays in good health:
- Tell us if a filter is bent or damaged
- Keep filter exchange and TR19 cleaning on the same plan
- Keep the canopy clear for exchange visits
- Report a dripping canopy early
Between visits, check that every filter is still in place. Gaps let grease into the plenum so tell us if you need a replacement.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
