School, care home and staff kitchens
Visits can be planned around holidays and quieter periods, keeping the filters ready for the busy weeks.
Grease filter exchange in Hatfield Hyde, done properly
In Hatfield Hyde, 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 gaps where filters have been removed and grease left in baffles after washing, we can help.
For a smaller kitchen near Hatfield Hyde, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site 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. In a place like Hatfield Hyde, we fit the visit around your hours.
- We start by noting how many filters you have and what type they are.
- We agree a schedule that suits how much the kitchen cooks.
- Each visit starts with the used filters being removed.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Preparing for the visit
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

Grease, kitchens and Hatfield Hyde
The FSA’s food hygiene register includes about 11 pubs and bars and about 3 hotels and guest houses in Hatfield Hyde and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Hatfield Hyde get their food hygiene inspections from Welwyn Hatfield council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Hatfield Hyde is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Hatfield House, about 1.7 miles south-west, is one of the historic houses near Hatfield Hyde; if you run event catering at a venue like that, cleans can be booked between functions. For schools such as Creswick Primary & Nursery School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

What affects the cost of grease filter exchange
The price is fixed before any work begins. It takes into account:
- How many systems or sites are involved
- The size of the system
- How easy every part is to reach
- One-off work versus a regular cycle
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
What to send for a quote
To help us quote quickly, send us:
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
When something else is needed
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- A canopy that doesn’t capture the vapour properly
- Grease deep in the extract system
- A heavily greased plenum or canopy, which needs cleaning to TR19
If in doubt, ring 0345 646 2711 or send us an email and we’ll say what we think before booking.
Parts of the system we cover
- Wall canopies
- Restaurants and pubs
- Baffle filters
- School and hospital kitchens
- Island canopies
- Mesh filters
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Facilities teams in offices, schools and healthcare sites book us too in Hatfield Hyde and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Between visits
Results last longer with the right care. Here’s what we suggest:
- Make sure no filter is left out
- Watch for grease drips between visits
- Report damaged filters so they can be replaced
- Always run the extract while cooking
The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to keep up.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
Common problems we fix in Hatfield Hyde
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.
Any of these means the system needs a check-up:
- A greasy plenum behind the filters
- Missing filters in the filter bank
- Poor airflow through the filters
- Damaged filters letting grease past
A hall kitchen that only cooks for events, whether near St Mary Magdalene Church or elsewhere in Hatfield Hyde, still needs its extract cleaned, just less often.

It depends on how much and what the kitchen cooks. Heavy cooking means more frequent changes than lighter ones. We agree the interval with you.
