Grease filter exchange in Newgate Street, done properly
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. Typical jobs include grease filters clogged with grease and a canopy that drips grease, across mesh filters, restaurants and pubs and island canopies.
In a village or hamlet like Newgate Street, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What happens if it’s left?
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy, and from there into the duct. Clean filters mean less fuel in the canopy. In a place like Newgate Street, ductwork and fans are easy to forget until something goes wrong.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Grease filter exchange in Newgate Street: the local picture
There are about 12 restaurants, cafés and canteens and about 3 takeaways within about 1.5 miles of central Newgate Street, according to the Food Standards Agency’s register. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. In Newgate Street, food businesses are inspected by environmental health officers from Welwyn Hatfield council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Hertfordshire Fire and Rescue Service covers Newgate Street. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Church and community hall kitchens, near Church of St Mary Ponsbourne or anywhere around Newgate Street, are easy to forget, but their extracts collect grease like any other. If you run catering at a historic house or estate in the area (Wyllyotts Manor is about 4 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning.
Newgate Street is about 3 miles north-west of Cheshunt, in Hertfordshire.

When something else is needed
We will not sell you work that does not address the problem, so here are the limits:
- A fan that’s failing or too weak for the system
- Smell complaints that need odour control equipment
- Grease behind the filters that a swap cannot remove
Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly before booking.
Parts of the system we cover
- School and hospital kitchens
- Wall canopies
- Restaurants and pubs
- Baffle filters
- Island canopies
- Mesh filters
Between visits
Aftercare is simple, and it helps at the next visit:
- Never leave gaps in the filter bank
- Clean the canopy surfaces regularly
- Mention it if the kitchen gets busier
- Look out for drips from the canopy
There’s no waiting: the canopy is ready as soon as the clean set is fitted. We take the greasy filters with us to be cleaned.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Common questions in Newgate Street
Who is the fire and rescue service for Newgate Street?
Fire safety enforcement in Newgate Street is handled by Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work overnight in Newgate Street?
Yes. We work evenings, overnight and at weekends. The work in Newgate Street can fit around your hours. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can we skip TR19 cleans if the filters are changed regularly?
No. The rest of the system still collects grease at an interval set by risk assessment.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them where they can be found quickly.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Fixed quotes for grease filter exchange in Newgate Street
The price is fixed before any work begins. It takes into account:
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.
Part by part
The plenum
The plenum is the space behind the filters. Grease that gets past the filters settles there.
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.
Common problems we fix in Newgate Street
Long cooking hours in Newgate Street or anywhere else mean more grease on the filters. A kitchen that cooks all day loads its filters quickly, so it needs more frequent changes.
Most sites get in touch after spotting one of these:
- Weak extraction at the canopy
- Filters so greasy the air can barely pass
- A canopy running with filters missing
- Damaged filters letting grease past
School kitchens, at schools like Ponsbourne St Mary's Church of England Primary School for example, are normally cleaned in the holidays so no lunches are lost.
