How we handle grease filter exchange in Theydon Bois
Filter exchange sits between full TR19® cleans. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. That’s why the whole system still needs cleaning to TR19 at the right interval. If you have grease dripping from the canopy and filters so greasy the air can barely pass, we can help, from baffle filters, school and hospital kitchens and mesh filters onwards.
In a smaller place like Theydon Bois, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.

Your questions about grease filter exchange in Theydon Bois
Who would carry out a food hygiene inspection at a kitchen in Theydon Bois?
Food hygiene inspections in Theydon Bois are carried out by Epping Forest council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Is Theydon Bois within the area you cover?
Yes. Theydon Bois is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What types of filter do you exchange?
Baffle and mesh filters are both covered. We check what’s in your canopies first and set up the service around them.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
Can damaged filters stay in the canopy?
Each filter is looked at when we exchange. We tell you about any that are damaged, because gaps let grease into the plenum.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Can you give a price for filter changes?
Every kitchen is different, so we quote once we know your filters and schedule. We give you a fixed quote before the service starts.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Tell us if the menu or opening hours change
- Keep canopy surfaces wiped down
- Watch for grease drips between visits
- Never leave gaps in the filter bank
Fresh filters improve airflow at the canopy from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Bent or missing filters let grease straight past. Replacing them early protects the plenum and ductwork.
When to call us in Theydon Bois
Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
The symptoms we are asked about most are:
- Filter washing that keeps being missed
- Damaged filters letting grease past
- Grease building up behind the canopy filters
- Poor airflow through the filters
A hospital like St. Margaret's Hospital, about 2.5 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
What your quote should include
- Whether the quote is based on a survey or photos
- Exactly which parts of the system are covered
- What happens if part of the system can’t be accessed
- What records you will receive afterwards
Different parts, different methods
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
Canopy filter housings
Filters sit in a housing or channel in the canopy. If it’s bent or greasy, filters will not seat properly.
Grease filter exchange in Theydon Bois: the local picture
According to Food Standards Agency records, there are about 6 pubs and bars within 1.5 miles or so of the middle of Theydon Bois. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for Theydon Bois is Essex County Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Environmental health officers from Epping Forest council inspect food businesses in Theydon Bois. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Volunteers running a hall kitchen near Parish Church of St Mary, or anywhere in Theydon Bois, may not know when the extract was last cleaned, and a grease test settles it. School kitchens, at schools like Theydon Bois Primary School for example, are usually cleaned in the holidays so no lunches are lost.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. 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. That part needs specialist access and equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
