Hertfordshire · Grease filter exchange
Grease filter exchange in Tonwell, Hertfordshire
Professional grease filter exchange in and around Tonwell, timed so the site keeps working and finished with a written report and photos.
- Filters that leave gaps in the canopy
- A canopy that drips grease
- Smoke and heat lingering under the hood
Different parts, different methods
The plenum
Behind the filters sits the plenum, where air gathers before the duct. It collects whatever grease the filters miss.
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.
Grease filter exchange in Tonwell
We set up grease filter exchange for kitchens in Tonwell on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing, lighter ones less. We agree the interval with you at the start. The work covers mesh filters, school and hospital kitchens and wall canopies, and common reasons people get in touch are blocked baffle filters and damaged filters letting grease past.
Somewhere as small as Tonwell, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What else we do in Tonwell
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes well under an hour for most canopies. Somewhere as small as Tonwell, the date and timings are agreed with you well before the day.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.

FAQs for Tonwell
Do you work overnight in Tonwell?
Yes, evening, overnight and weekend work is normal for us. That way a site in Tonwell does not have to lose a day’s trading. Just phone us on 0345 646 2711 or email us with your opening times and we’ll plan around them.
Who enforces fire safety at workplaces in Tonwell?
Fire safety enforcement in Tonwell is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you clean filters as well as exchanging them?
Yes, filter cleaning is available. We will check your filters first, as damaged ones may be better replaced.
Is TR19 cleaning required by law?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Is filter exchange enough instead of a full extract clean?
No, the two work together. A TR19® clean deals with the whole system, with a certificate and photo report.
What accreditations do you have?
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.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
Managing agents and facilities teams in Tonwell
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Larger estates can be phased building by building around the people who use them.
When it’s something else
We will not sell you work that doesn’t address the problem, so here are the limits:
- A canopy too small for the cooking beneath it
- Greasy ducts and risers that a filter change will not reach
- A noisy or failed extract fan
Not sure which it is? You can ring 0345 646 2711, or send details by email and we’ll tell you honestly before you book.
What we work on in Tonwell

What grease filter exchange looks like in Tonwell
Food Standards Agency data counts about 4 restaurants, cafés and canteens across Tonwell and its immediate surroundings (about a mile and a half). Swapping filters on a schedule keeps kitchens like these drawing air properly. Kitchens in Tonwell get their food hygiene inspections from East Hertfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Tonwell sits within the area of Hertfordshire 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.
Historic houses near Tonwell, such as Aston Bury about 4.6 miles north-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Bursars and site managers at schools such as Tonwell St Mary's Church of England Primary School tend to book extract cleaning for when the kitchen is empty. A hospital like Hertford County Hospital, about 3 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Keep canopy surfaces wiped down
- Report damaged filters so they can be replaced
- Keep filter exchange and TR19 cleaning on the same plan
- Make sure we can reach the canopy on exchange day
Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
Leave it or put it right?
Grease-loaded filters are a fire risk in their own right. A flare-up on the range can reach them, and from there into the duct. Keeping filters clean takes some of that fuel away. It’s simpler to plan the work at Tonwell now than to arrange it in a hurry later.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711, or send details by email, and we’ll talk you through it.
