Sleapshyde kitchens: local notes
Food Standards Agency data counts about 35 restaurants, cafés and works canteens and about 13 takeaways and sandwich shops within 1.5 miles or so of the middle of Sleapshyde. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Hertfordshire Fire and Rescue Service covers Sleapshyde. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s St Albans City council that sends environmental health officers to food businesses in Sleapshyde. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Historic houses near Sleapshyde, such as Hatfield House about 2.5 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. If you look after a school kitchen, at a school such as Colney Heath Junior Mixed Infant and Nursery School or anywhere near Sleapshyde, the holidays are the usual time for a TR19® clean. A hospital like Hill End Hospital, about 1.7 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Questions from Sleapshyde
Who is the fire and rescue service for Sleapshyde?
That is Hertfordshire Fire and Rescue Service. 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.
Who carries out food hygiene inspections in Sleapshyde?
The local authority for Sleapshyde is St Albans City council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What should I send you?
Some photos and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
Why has my extract fan got louder?
Build-up on the impeller is a frequent reason, since uneven grease makes it run out of balance. It can also be wear in the bearings or motor, which our report will flag.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Leave it or put it right?
Without a working extract fan, a kitchen cannot cook safely. Many fan problems start with grease, so cleaning the fan helps keep it working. If it does fail, our 24/7 emergency line is there. If the system at a site near Sleapshyde fails, there may be nowhere nearby to move to.

Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
How we price extract fan cleaning
Every site gets its own quote. These are the things that affect it:
- Parking and loading at the site
- Whether we need access equipment or extra panels
- The number of sites or systems
- The times the site is available
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
Helping us quote
We can often survey from pictures. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or send us an email.
How the visit works
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 we take it from there. Afterwards, the area is left tidy and the written report follows. A quick note on how to find the site and where to park makes a visit to Sleapshyde run smoothly.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it cannot start while we work.
- We remove the grease from the blades, impeller and casing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Find the previous report, if there is one
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Between visits
So the system stays in good health:
- Make sure the fan is included each time
- Keep records of every fan clean
- Listen for new noises or vibration from the fan
- Check filters are seated before cooking
If the fan needs more than a clean, we will say so plainly. We also repair and replace extract fans, so you have one point of contact.
Run the fan throughout cooking. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.

What the work involves, part by part
Inline duct fans
Inline fans can be in tight spaces, so the method is planned in advance. Anything out of reach is recorded.
Roof-mounted fans
On a roof, the air is cooler and grease drops out faster. We scrape and degrease the blades and casing.
When it’s something else
In fairness, there are a few things this work will not fix:
- A failed motor or worn bearings (that needs a fan repair or replacement)
- An impeller that is bent or split
- Wiring faults to the fan
If you are not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
