How we handle extract fan cleaning in Hatfield
The extract fan is the heart of the system: it draws the air through the canopy and ductwork and pushes it outside. Grease that gets past everything else ends up on its blades and housing and we clean it off. If you have an extract fan that vibrates or rattles and grease around the motor and its mounts, we can put it right.
Around a town like Hatfield, extract cleaning usually 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.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Managing agents and facilities teams in Hatfield
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.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

What else we do in Hatfield
Between visits
Once we’ve finished, these simple steps help:
- Tell us if the extract feels weaker
- Listen for new noises or vibration from the fan
- Report grease escaping from the fan
- Keep records of every fan clean
Where the fan needs repair rather than cleaning, the report says so. Fan repair and replacement are services we offer too, so you have one point of contact.
Do not run the kitchen with the extract off. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
How the job changes from site to site
Impellers and blades
The blades of the impeller do the work, and grease builds up on them unevenly. That is what unbalances the fan, so it’s cleaned carefully blade by blade.
Roof-mounted fans
A roof fan sits in cooler air, so grease can settle heavily. The impeller and housing are scraped and degreased.
Leave it or put it right?
The fan is part of the fire path. A TR19 clean that left out the fan wouldn’t cover the whole system and many insurers require the full system to be cleaned to TR19. Each month of use adds to the build-up, so a site in Hatfield is better off booking it now.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes a couple of hours per fan, depending on its size and the build-up. In a town like Hatfield, we usually work after closing or on a quiet day, so the site opens again on time.
- We find the fan and check how it’s reached and how it’s isolated.
- Power to the fan is isolated before anyone touches it.
- Grease is scraped from the impeller blades and the inside of the housing.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
How to prepare
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive

What extract fan cleaning looks like in Hatfield
According to Food Standards Agency records, there are about 15 pubs and bars across Hatfield and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In Hatfield, food businesses are inspected by environmental health officers 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 is 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.
If you run a church or community hall kitchen, near Church of St Luke or elsewhere in Hatfield, its extract still collects grease from every lunch and event. If you cook for passing trade around Hatfield station, the extract can be cleaned between your last and first customer. If you run catering at a healthcare site, such as a hospital like Queen Elizabeth II Hospital about 2.4 miles north-east, the extract may need cleaning more often than a part-time kitchen.

Questions from Hatfield
Who carries out food hygiene inspections in Hatfield?
In Hatfield, it’s Welwyn Hatfield council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Who enforces fire safety at workplaces in Hatfield?
That’s Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. 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.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
What’s the cleaning interval for an extract fan?
Daily cooking hours set the minimum, under BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
