How we handle grease filter exchange in Letchworth
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. We are often asked to deal with blocked baffle filters and damaged filters letting grease past, on island canopies, mesh filters and wall canopies.
Many kitchens in a town like Letchworth were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Tell us if a filter is bent or damaged
- Clear anything stored on or near the canopy
- Keep every filter in place during service
- Book full TR19 cleans alongside filter changes
The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to keep up.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.
FAQs for Letchworth
Which fire authority looks after Letchworth?
Fire safety enforcement in Letchworth 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.
Can the work in Letchworth be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you have insurance?
Yes. We carry full insurance, and we have been trading since 2009.

On site, it takes well under an hour for most canopies. Bigger or more complicated systems take longer, and we’ll tell you what to expect.
What if some of our filters are damaged?
A bent filter leaves a gap for grease. We point them out on the visit and explain what’s needed.
What paperwork should we keep on file?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
How regularly do grease filters need exchanging?
It varies from kitchen to kitchen. The schedule is based on how heavily you cook, and adjust it if needed.
What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a short visit, depending on how many filters the canopies hold. In Letchworth, the visit is planned around your opening hours, parking and access to the system.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
How to prepare

Different parts, different methods
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is usually the tightest.
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota so the filters are clean when cooking picks up.
