How we handle extract fan cleaning in North Mymms

If you have burning smells from the fan area and rough running from the extract fan, we can help.
Work in a small place like North Mymms starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Multi-site and managed buildings
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 can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Note any drop in extraction at the canopy
- Listen for new noises or vibration from the fan
- Leave a clear route to the fan
- Never cook with a filter missing
When we’ve finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Do not run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Common questions in North Mymms
Who enforces fire safety at workplaces in North Mymms?
It’s Hertfordshire Fire and Rescue Service, which covers North Mymms. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which council inspects kitchens in North Mymms?
That is Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in North Mymms. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How long does extract fan cleaning take?
Allow a few hours where there are several fans or heavy deposits. We’ll confirm the time when we quote.
What do you do to 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.
Can you fix a fan that is worn out?
We also repair and replace extract fans. If cleaning shows a worn motor, bearings or impeller, we will tell you and quote for the repair.
How often should the extract fan be cleaned?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Readings may show it needs cleaning more often.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Kitchen extracts in North Mymms
According to Food Standards Agency records, there are about 4 pubs and bars in North Mymms and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. North Mymms 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. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in North Mymms. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
For schools such as Brookmans Park Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If you run catering at a healthcare site, such as a hospital like Shenley Hospital about 3.5 miles south-west, the extract may need cleaning more often than a part-time kitchen.
North Mymms is about 2 miles north-west of Potters Bar, in Hertfordshire.

What’s near North Mymms
Around North Mymms, our work takes us to kitchens and buildings near Chancellor's School, North Mimms Park and The Old Maypole Public House. North Mymms’s nearest station is Brookmans Park station, roughly 0.7 miles east. Other landmarks nearby include Shenley Hospital (3.5 miles south-west) and Potters Bar Museum (2 miles south-east). The countryside around North Mymms includes Furzefield Wood and Lower Halfpenny.
What happens if it’s left?
Grease on the impeller makes the fan less efficient. Less air is pulled from the kitchen, so heat and smoke linger and the motor works harder. Out of sight is the usual reason a rural system goes too long without attention.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
What affects the quote in North Mymms
Before we fix a price, we need to know a few things. We check:
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- Whether we need access equipment or extra panels
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.
What to send for a quote
You do not need the technical terms. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Any previous report or certificate
- Your opening hours and when the area is out of use
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

When to call us in North Mymms
Poor filters mean a greasier fan. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
Keep an eye out for any of the following:
- An extract fan with no cleaning record
- A fan that no longer moves enough air
- A fan coated in grease inside its housing
- Hot, greasy smells near the fan
If you cook for passing trade around Brookmans Park station, the extract can be cleaned between your last and first customer.
