How we handle grease filter exchange in Deacon's Hill
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers baffle filters, mesh filters and restaurants and pubs, and common reasons people get in touch are damaged filters letting grease past and a canopy that drips grease.
In a village or hamlet like Deacon's Hill, the kitchens that need extract cleaning are usually 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.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Grease filter exchange in Deacon's Hill: the local picture
Food Standards Agency data counts about 50 restaurants, cafés and works canteens and about 26 sandwich bars and takeaways in and around Deacon's Hill, up to about a mile and a half out. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Food hygiene inspections in Deacon's Hill are the job of Hertsmere council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Hertfordshire Fire and Rescue Service covers Deacon's Hill. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Filters get bent and damaged with handling. A bent filter doesn’t seat properly, leaving gaps for grease to slip through.
What we are most often called out for:
- Poor airflow through the filters
- Missing filters in the filter bank
- Bent or damaged filters that do not sit properly
- Blocked baffle filters
Bursars and site managers at schools such as Summerswood Primary School tend to book extract cleaning for when the kitchen is empty.

Your questions about grease filter exchange in Deacon's Hill
Which council inspects kitchens in Deacon's Hill?
That is Hertsmere council, whose environmental health officers carry out food hygiene inspections in Deacon's Hill. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Who is the fire and rescue service for Deacon's Hill?
Fire safety enforcement in Deacon's Hill 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.
How regularly do grease filters need exchanging?
It varies from kitchen to kitchen. We look at your cooking and set an interval to match and can change if your kitchen gets busier.
Do you recommend a next date?
Yes. The report recommends when the next visit should be, based on what we found and how the system is used.
How much notice do you need?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Do you take the used filters away?
We do. The dirty filters are taken away for cleaning and the clean set stays in the canopy.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What types of filter do you exchange?
Baffle filters and mesh filters. Mention how many canopies you have when you get in touch and we’ll confirm it on site.
What the work involves, part by part
The plenum
Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.
Canopy filter housings
Every exchange includes a check of how the filters sit since a gap is a route for grease.
Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Never cook with the extract switched off
- Don’t let the full clean slip because filters are changed
- Don’t refit a filter that is bent
- Make sure no filter is left out
Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and tell us if service times change.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
How we price grease filter exchange
There’s no set price list, because no two systems are the same. The quote depends on:
- Whether several sites go on one quote
- Site rules, permits and inductions
- How big the system is
- Travel, parking and unloading
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Helping us quote
To speed up the quote, please include:
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
