Common questions in St Leonards
Do you work overnight in St Leonards?
Yes. We work evenings, overnight and at weekends. It means the site in St Leonards keeps running as normal. Just give us a ring on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Which fire authority looks after St Leonards?
Fire safety enforcement in St Leonards is handled by Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Are you accredited for kitchen extract cleaning?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we’re fully insured.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
TR19 kitchen extract cleaning in St Leonards
Duct Doctor has been cleaning kitchen extract systems since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured. The work covers horizontal duct runs, vertical risers and canopies and hoods, and the jobs we see most are an inspection that picked up a dirty extract and a kitchen taken over without any extract records. Some call it canopy cleaning, others extract cleaning or duct cleaning, but a proper TR19® clean in St Leonards covers all of it, from the hood to the fan.
Kitchens that fry and grill hardest need the most frequent cleans, so the interval is set by what you cook as well as how long.
For a kitchen in or near St Leonards, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Signs you need kitchen extract cleaning in St Leonards
In St Leonards, as anywhere, grease gathers where the air slows down: long horizontal runs, bends, the base of risers and around the fan. Cooler sections of duct collect the most.
What we are most often called out for:
- Grease smells coming from the extract
- A kitchen with no current TR19 certificate
- A new tenancy or takeover with no cleaning history
- Ductwork thick with old, hardened grease
A hall kitchen that only cooks for events, whether near Church of St Leonard or elsewhere in St Leonards, still needs its extract cleaned, just less often.

Leave it or put it right?
After a fire, one of the first questions is often when the extract was last cleaned. Many insurers ask for proof of TR19 cleaning and may reduce or refuse a claim without it. A current certificate is far easier to produce than an explanation. With notice, the visit to St Leonards can be fitted around your bookings and events.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.

Between visits
A little care between visits keeps the system in better shape. Our advice:
- Keep the baffle filters clean
- Give the canopy a daily wipe
- Tell us when the extract starts to drip or smell
- Empty any grease troughs or cups on the canopy
Any section without access is marked on the report. A TR19 report should record what wasn’t cleaned as well as what was, and new access panels can be fitted so the next clean covers it.
Book the next clean before the last one runs out. If the kitchen starts cooking longer hours, the interval should be looked at again, and grease readings will show it.
Kitchen extract cleaning around St Leonards
We cover St Leonards, about 31 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible. St Leonards sits within the area of 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.
If you run catering at a healthcare site, such as a hospital like Chiltern Hospital about 4.7 miles south, the extract may need cleaning more often than a part-time kitchen. If you run catering at a historic house or estate in the area (Cholesbury Manor House is about 1.1 miles east), event kitchens in older buildings often have awkward duct runs that need planning.

What kitchen extract cleaning can’t fix
Before booking, it helps to know what’s not included:
- Fire dampers that will not close (that needs damper testing and remedials)
- Ductwork that is corroded, split or leaking (that’s for a ductwork contractor)
- A grease trap that needs emptying

For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes one visit for most kitchens, while large or complex systems may need more than one. Somewhere like St Leonards, lanes, gates and parking are worth mentioning in advance.
- You send pictures or we visit, and the system is surveyed from canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- We re-test, photograph and send your certificate and photo report.
Getting ready for the visit
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading

Schools, hospitals and care homes
Institutional kitchens tend to cook to set hours, so cleans can be planned for holidays or quiet times. The certificate and report suit estates and compliance files.
Canopy and plenum
The plenum is out of sight behind the filters, so it’s easy to forget. With the filters out, the plenum is scraped and degreased.
