Grease, kitchens and Deacon's Hill
The FSA’s food hygiene register shows about 50 restaurants, cafés and canteens and about 26 sandwich bars and takeaways across Deacon's Hill and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Deacon's Hill sits within the area of 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. It’s Hertsmere council that sends environmental health officers to food businesses in Deacon's Hill. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand.
If you run catering at a healthcare site, such as a hospital like Royal National Orthopaedic Hospital about 1.4 miles south-west, the extract may need cleaning more often than a part-time kitchen. If you cook for passing trade around Elstree & Borehamwood station, the extract can be cleaned between your last and first customer.

Extract fan cleaning in Deacon's Hill
Cleaning removes grease, not wear. Anything that looks worn or damaged goes on the report, and we also repair and replace extract fans. You’ll know whether the fan just needed cleaning or something more. The work covers in-line fans, roof-mounted fans and axial fans, and people most often call us about a fan left out of previous cleans and a fan motor running hot under a coat of grease.
For a kitchen in or near Deacon's Hill, the visit is planned around opening hours and the journey, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Honest limits
Extract fan cleaning cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- A dirty duct upstream of the fan
- Damaged fan blades
- Electrical faults in the fan’s supply or controls (an electrician’s job)

What else we do in Deacon's Hill
When to call us in Deacon's Hill
The fan sits at the end of the grease’s journey. Whatever grease is still in it settles on the impeller and inside the housing, and the spinning blades fling it onto the walls of the housing.
These are the problems we see most often:
- A smell of hot grease from the extract
- A fan coated in grease inside its housing
- A fan left out of previous cleans
- A fan shaking on its mounts
Bursars and site managers at schools such as Summerswood Primary School tend to book extract cleaning for when the kitchen is empty.

How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes an hour or two for one fan, longer when it’s hard to reach. A few photos of the system help us make the most of a visit to a place like Deacon's Hill.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
Getting ready for the visit
- Arrange a key holder or contact on site
- Move anything stored near the system
- Tell us about site rules, permits or sign-in

Why it’s worth doing now in Deacon's Hill
Grease on the fan is grease in the system. TR19® Grease covers the whole extract, fan included and many insurers require the full system to be cleaned to TR19. A planned visit to Deacon's Hill is easier to arrange than an emergency callout.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.
Why book with us
- Every job surveyed first
- We’re fully insured

- Fixed quotes from a survey or pictures
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep the fan on whenever the range is lit
- Do not store items in front of the fan’s access point
- Flag smoke lingering at the canopy
- Check filters are seated before cooking
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Keep the whole system on its cleaning cycle. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
Deacon's Hill: your questions answered
Can a school canteen extract in Deacon's Hill be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. There are about 18 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Deacon's Hill. Send us your term dates when you call 0345 646 2711 or email us, and we’ll fit the work in.
Who is the fire and rescue service for Deacon's Hill?
It’s Hertfordshire Fire and Rescue Service, which covers Deacon's Hill. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you need to turn the fan off to clean it?
With the fan isolated, the extract is not running. We work evenings, overnight or weekends, and the kitchen is ready when we leave.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Do you work in Deacon's Hill?
Yes. We work in Deacon's Hill and the rest of Hertfordshire, within our South East and London area. To book, give us a ring on 0345 646 2711 or use the quote form.
Can you clean the fan on its own?
Yes, if the fan needs it. We’ll often suggest checking the duct too, as a greasy fan typically means a greasy duct, but the choice is yours.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
What happens to the waste?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, 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: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
