Grease filter exchange in Digswell
In Digswell, our filter exchange runs on a schedule set by how much the kitchen cooks. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. We agree the interval with you at the start. If you’re dealing with bent or damaged filters that don’t sit properly and grease dripping from the canopy, we can help.
In a smaller place like Digswell, 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 cleaning is planned around how much it cooks and what the readings show.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Busy restaurant and pub kitchens
Heavy cooking means more grease reaching every part of the system. Regular changes help protect the ductwork.
Baffle filters
A clogged baffle filter restricts airflow. A clean exchange set brings the airflow back.
How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Visits to a place like Digswell are planned ahead, so we arrive with what the survey says the job needs.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Before we arrive
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

What grease filter exchange looks like in Digswell
According to Food Standards Agency records, there are about 16 pubs, bars and clubs within roughly a mile and a half of the centre of Digswell. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Digswell. 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. Digswell sits within the area of Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Term dates shape school work: for a school like Harwood Hill Junior Mixed Infant and Nursery School, an extract clean fits neatly into a half-term or summer break. A kitchen near Welwyn North station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. If you run catering at a healthcare site, such as a hospital like Queen Elizabeth II Hospital about 2.5 miles south, the extract may need cleaning more often than a part-time kitchen.

Between visits
Here’s the after-treatment advice, short and simple:
- Tell us if the menu or opening hours change
- Keep canopy surfaces wiped down
- Keep every filter in place during service
- Tell us if a filter is bent or damaged
The next exchange is already in the diary. If cooking increases, we can change filters more often to keep up.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule means neither slips.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
In-house cleaning or a specialist?
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 is our job.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
How we price grease filter exchange
There’s no set price list, because no two systems are the same. What we look at:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- The number of sites or systems
- Where the site is and how we reach it
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 work begins.
Helping us quote
To help us quote quickly, please include:
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
When something else is needed
Some problems need a different service or another trade:
- Grease deep in the extract system
- Grease behind the filters that a swap cannot remove
- Extraction problems caused by the fan rather than the filters
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Baffle filters
- Wall canopies
- Mesh filters
- Island canopies

Questions from Digswell
Which fire and rescue service is responsible for Digswell?
That’s Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can a school canteen extract in Digswell be done out of term time?
Yes, and it’s the easiest time to do it. With about 15 schools and colleges on the FSA’s register within roughly a mile and a half of Digswell, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Where do the greasy filters go?
Yes. The dirty filters are taken away for cleaning while a clean set goes in.
Do you cover Digswell?
Yes. Digswell is part of the area we cover, within the South East and London area we cover.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
How long will you be on site?
It depends on the size of the system, but for a typical site it takes a short visit, depending on how many filters the canopies hold. We’ll confirm it with the quote.
