About our grease filter exchange in Welwyn Garden City
Each visit is quick and tidy. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. If something looks wrong, we tell you. We’re often asked to deal with grease collecting in the filter channels and filter washing that keeps being missed, on baffle filters, island canopies and school and hospital kitchens.
Around a town like Welwyn Garden City, extract cleaning normally means a restaurant, pub, takeaway or the kitchen of a school or care home. Each has a canopy, filters, ductwork and a fan to keep clear of grease, and each is cleaned to the same TR19® standard.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes anything from a few minutes to an hour or so, depending on the number of filters, and the area is cleaned down before we leave. Before the visit, a few photos of the system and how to reach it help us plan the work in Welwyn Garden City.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Before we arrive
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
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.

How we price grease filter exchange
The diagnosis comes before the price. The main factors are:
- The scale of the work
- The times the site is available
- Whether we need access equipment or extra panels
- Any permits to work or inductions
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
When you call or email, these details help:
- Wide pictures of the system and the area around it

What the work involves, part by part
Mesh filters
Mesh filters are still found in many canopies. We exchange them on the same basis as baffles.
School, care home and staff kitchens
Kitchens that cook for set mealtimes still load their filters, though often more slowly.
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Tell us if the menu or opening hours change
- Do not let the full clean slip because filters are changed
- Do not refit a filter that is bent
- Clear anything stored on or near the canopy
The canopy looks cleaner and the air moves better from the moment they’re fitted. Always run the extract during cooking so they catch grease as intended.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
Your questions about grease filter exchange in Welwyn Garden City
Do you clean school canteen extracts around Welwyn Garden City out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 21 schools and colleges with food registrations within roughly a mile and a half of Welwyn Garden City. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
Who carries out food hygiene inspections in Welwyn Garden City?
That’s Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in Welwyn Garden City. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Where do the greasy filters go?
We take them away. That’s the point of an exchange: clean filters in, dirty ones out, with no washing for your team.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you clean our existing filters instead?
We offer filter cleaning as well as exchange. We will talk you through which suits your kitchen when you get in touch.
Do you recommend a next date?
Yes. How often depends on use and condition and the report sets out why.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. 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.
