How we handle grease filter exchange in Hatfield
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the fan has to work harder. Regular exchange keeps the air moving. If you have grease filters clogged with grease and hand-washed filters that still look greasy, we can put it right, from wall canopies, island canopies and restaurants and pubs onwards.
For a pub, café or restaurant in a town like Hatfield, losing a day’s trade to cleaning is not an option, so the work is done after service, overnight or on a closed day. By the next service, the kitchen is ready to cook in again.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What we’re called out for in Hatfield
Cooking vapour carries grease into the canopy. Much of it is trapped by the filters, and day by day they load up and airflow falls away.
It’s time to book a visit if you see:
- Filter washing that keeps being missed
- Missing filters in the filter bank
- Grease left in baffles after washing
- Grease filters clogged with grease
Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 2.4 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
What your quote should include

Hatfield questions
Do you clean school canteen extracts around Hatfield out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of Hatfield. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Can the work in Hatfield be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Hatfield does not have to lose a day’s trading. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Can we skip TR19 cleans if the filters are changed regularly?
No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
How much notice should we give?
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.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What if some of our filters are damaged?
We check every filter at each visit. We tell you about any that are damaged since a poor fit lets grease past.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Who is the responsible person?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Grease filter exchange around Hatfield
The FSA’s food hygiene register shows about 65 cafés, restaurants and staff canteens and about 28 takeaways within about 1.5 miles of central Hatfield. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Environmental health officers from Welwyn Hatfield council inspect food businesses in Hatfield. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Hatfield sits within the area of Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Church and community hall kitchens, near Church of St Luke or anywhere around Hatfield, are easy to forget, but their extracts collect grease like any other. A kitchen near Hatfield station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Make sure we can reach the canopy on exchange day
- Report damaged filters so they can be replaced
- Never cook with the extract switched off
- Never leave gaps in the filter bank
The canopy looks cleaner and the air moves better right away. Keep the extract running while you cook so they catch grease as intended.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a few minutes per canopy, longer for a large kitchen with several canopies. A closed day, an evening or an early start: whichever suits your site in Hatfield, we’ll book around it.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Getting 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.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
