Woollensbrook questions
Can you clean school kitchen extracts in Woollensbrook during the holidays?
Yes, out-of-term visits are normal for schools. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Woollensbrook. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Do you work overnight in Woollensbrook?
Yes, evening, overnight and weekend work is normal for us. That way a site in Woollensbrook doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
About our grease filter exchange in Woollensbrook
We run grease filter exchange for all kinds of kitchens in Woollensbrook, from a single canopy to several. We can come before or after service so nobody has to stop cooking. If you’re dealing with smoke and heat lingering under the hood and grease building up behind the canopy filters, we can put it right.
Work in a small place like Woollensbrook starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Grease filter exchange in Woollensbrook: the local picture
Food Standards Agency records include about 12 pubs, bars and clubs in and around Woollensbrook, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Woollensbrook 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. Kitchens in Woollensbrook get their food hygiene inspections from Broxbourne council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Woollensbrook is Hertford County Hospital, about 3.1 miles north-west. Where a hall near Church of St Catherine & St Paul, or anywhere in Woollensbrook, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

When to call us in Woollensbrook
Washing filters by hand does not always get them clean. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
Most sites get in touch when they notice something like this:
- A canopy running with filters missing
- Damaged filters letting grease past
- Filter washing that keeps being missed
- Grease collecting in the filter channels
School kitchens, at schools like Westfield Community Primary School for example, are usually cleaned in the holidays so no lunches are lost.

- Whether a written report and pictures are included
The process
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. A few photos of the system help us make the most of a visit to a place like Woollensbrook.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Clear the space around the work
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

What happens if it’s left?
Dripping canopies and greasy smells often start with the filters. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. Out of sight is the usual reason a rural system goes too long without attention.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.

What the work involves, part by part
Mesh filters
Grease lodges deep in the layers of a mesh filter, so a quick rinse rarely gets it clean.
Busy restaurant and pub kitchens
When service is non-stop, filters get forgotten. A regular exchange means nobody has to remember.

What affects the cost of grease filter exchange
Sites vary more than people expect. What affects the quote:
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- The condition of the system
- Travel, parking and unloading
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before work begins.
What to send for a quote
There’s no need for technical detail. Just send:
- Your last certificate, test record or report
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

- Baffle filters
- Island canopies
- Mesh filters
- Restaurants and pubs

Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Never cook with the extract switched off
- Make sure we can reach the canopy on exchange day
- Book full TR19 cleans alongside filter changes
- Wipe the outside of the canopy as part of daily cleaning
Nothing changes for your staff, except one less greasy job. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.
Filter exchange and TR19 cleaning work best together. Setting both up on a schedule keeps everything on track.
