Kitchen extract cleaning in Leavesden, done properly
Not sure when the extract was last cleaned, or by whom? Just call 0345 646 2711 or send us an email with photos of the canopy and filters, and you will have a fixed quote for kitchen extract cleaning in Leavesden, usually within one working day. If you have ductwork thick with old, hardened grease and a kitchen with no current TR19 certificate, we can put it right, from extract fans, horizontal duct runs and plenums and filters onwards. For TR19 kitchen extract cleaning in Leavesden, one call covers the survey, the clean and the paperwork, wherever you are in Hertfordshire.
What can be cleaned depends on what can be reached. Sections without access panels are recorded on the report, and new panels can be fitted so they’re cleaned next time.
Kitchens around a place like Leavesden are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Leave it or put it right?
Every week without a clean adds another layer. BESA guidance says the mean should not go above 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. The longer it’s left, the bigger the job becomes. It’s better to plan the work at a site near Leavesden than wait for a failure.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before any work starts.

Aftercare tips
Results last longer with the right care. We suggest:
- Empty any grease troughs or cups on the canopy
- Keep the TR19 certificate and photo report in the maintenance log
- Keep to the recommended cleaning interval
- Flag any change in how the extract sounds or works
The kitchen is left clean and ready for the next service. Waste grease and water are contained and removed, so you can start cooking as normal.
Clean the grease filters often, not just on clean day. Clean, well-fitted filters catch more fat before it reaches the duct, which slows build-up further down the system.
What we’re called out for in Leavesden
Grease in an extract starts as vapour. As the air cools on its way through the duct, the fat condenses and sticks, and the layer grows a little with every meal cooked. The grease filters stop some, never all of it.
Common reasons sites call us are:
- Grease dripping from the canopy or filters
- An overdue clean flagged by an EHO or fire officer
- Poor airflow at the canopy
- A kitchen taken over without any extract records
Historic houses near Leavesden, such as High Elms Manor about 0.4 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Kitchen extracts in Leavesden
There are about 40 restaurants, cafés and canteens and about 24 takeaways in Leavesden and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. Every kitchen in that count with a canopy has a full extract system, canopy to discharge, to keep clear of grease. Fire safety in Leavesden falls to Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Leavesden are the job of Three Rivers council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
Church and community hall kitchens, near Church of All Saints or anywhere around Leavesden, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Leavesden is Leavesden Hospital, about 0.6 miles north-west.

The process
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a single shift for most kitchens, with long duct runs and tall risers needing more time. In a place like Leavesden, we fit the visit around your hours.
- We survey the system, from your photos or on site, canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- On the night, the equipment is off and cool and the kitchen is sheeted.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- Readings are repeated, photos taken, and your TR19 certificate and photo report issued.
Before we arrive
- Name a contact who can let us in at the agreed time
- Clear the space around the work

Advice
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Your questions about kitchen extract cleaning in Leavesden
Do you work overnight in Leavesden?
Yes. We work evenings, overnight and at weekends. The work in Leavesden can fit around your hours. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
Which fire authority looks after Leavesden?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Leavesden. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Does the law say I must clean to TR19?
No law names TR19 directly, but the Fire Safety Order 2005 does require the responsible person to manage fire risk. Insurers, fire officers and EHOs look to TR19 as the standard, and many policies require it.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
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. Larger or hidden systems need a survey on site first.
How long does it take to clean a kitchen extract system?
It takes a few hours for a small kitchen, longer for a large system. We will confirm the time when we quote.
Will I get a certificate after the clean?
A TR19 certificate, plus a full photo report. The report lists what was cleaned, anything we couldn’t reach and when the next clean is due.
Fixed quotes for kitchen extract cleaning in Leavesden
A fixed price needs a few facts first. We look at:
- How easy every part is to reach
- Whether it’s a one-off visit or part of a schedule

Helping us quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- The paperwork from the last visit, if you have it
The quickest way to a quote is to send photos: 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 many jobs can be priced from that alone.
