For landlords and multi-site operators
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.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
How we handle TR19 inspection in Sleapshyde
A pre-clean survey looks at the whole system, from canopy to discharge. We check where the access panels are and whether every section can be reached, and grease readings are taken at set points. If you’re dealing with insurance renewals needing proof of TR19 cleaning and kitchens taken over with no cleaning records, we can put it right.
Work in a small place like Sleapshyde 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How it works
There’s very little for your team to do 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. Visits to a village like Sleapshyde are booked in advance, at a time that suits whoever runs the site.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and photos recorded.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload

Advice
Questions from Sleapshyde
Do you do school kitchen extract cleaning in Sleapshyde in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Sleapshyde. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Who is the fire and rescue service for Sleapshyde?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Sleapshyde. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What do the grease readings need to be?
Between cleans, the mean should stay at 200 microns or below, with 500 microns or more anywhere needing immediate spot cleaning.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What happens if you cannot reach some of it?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Is a quote from photos possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
Do you work out of hours?
Yes. Much of our work happens in the evening, overnight or at weekends, so you don’t have to close during trading.
Common problems we fix in Sleapshyde
Grease builds up as cooking vapour cools inside the extract. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Clients typically contact us when they notice something like this:
- Missing TR19 certificates or history
- Extracts that have never been grease tested
- Surveys needed before quoting a full clean
- Post-clean verification after another contractor’s clean
If you run catering at a historic house or estate in the area (Hatfield House is about 2.5 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning.
What your quote should include
- Whether inaccessible sections are listed on the report
- Whether the work can be done while the site is closed
- If the quote is a fixed price or an estimate
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Diary the next grease test and clean
- Flag oily drips near the extract
- Wipe the canopy surfaces regularly
- Have the latest report ready for insurance renewals
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
Keep certificates, reports and readings in one place so the history is easy to show.
Why deal with it now?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. In a place like Sleapshyde, ductwork and fans are easy to forget until something goes wrong.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Inspections are planned around mealtimes and holidays to avoid disruption.
Grease, kitchens and Sleapshyde
Food Standards Agency records include about 9 bars, pubs and nightclubs within about 1.5 miles of central Sleapshyde. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Sleapshyde get their food hygiene inspections from St Albans City council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Sleapshyde 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.
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. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hill End Hospital is the nearest hospital to Sleapshyde, about 1.7 miles west.

In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
