TR19 kitchen extract cleaning in Tewin Wood
Think of it as a health check for the kitchen’s airways: diagnose with a survey, treat with a thorough clean, then sign it off. The sign-off is a TR19 certificate with a photo report, issued through the BESCA Vent Hygiene Elite portal. The work covers extract fans, plenums and filters and horizontal duct runs, and common reasons people get in touch are ductwork thick with old, hardened grease and an inspection that picked up a dirty extract. If you need a kitchen extract clean in Tewin Wood, you get one team and one number for every site.
BESA sets minimum intervals by hours of cooking a day: every 3 months for 12–16 hours, every 6 months for 6–12 hours and every 12 months for 2–6 hours, adjusted by what the grease readings show.
For a kitchen in or near Tewin Wood, the visit is planned around opening hours and the journey, 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.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we do, step by step
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. The visit itself takes one visit for most kitchens, while large or complex systems may need more than one. Somewhere as small as Tewin Wood, the date and timings are agreed with you well before the day.
- 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.
- 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.
How to prepare
- Tell us about site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use

Advice
Places near Tewin Wood
What else we do in Tewin Wood
What we’re called out for in Tewin Wood
We often find duct sections that haven’t been cleaned since they were installed. Most of the time it’s because there were never enough access panels, so nobody could get to them. Grease in those sections keeps building out of sight.
The symptoms we’re asked about most are:
- Missing paperwork after a change of operator
- Heavy grease build-up inside the duct runs
- An extract that no longer clears the smoke
- Grease smells coming from the extract
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Queen Elizabeth II Hospital is the nearest hospital to Tewin Wood, about 3.5 miles south.
What your quote should include
- When they can work, and whether that is outside your opening hours
- Whether the figure could change on the day
- What insurance they carry
- Which accreditations they hold, and whether you can check them
What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Why deal with it now?
Putting it off simply moves the grease further down the duct. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Regular cleans keep each visit shorter. Out of sight is the usual reason a rural system goes too long without attention.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

How we price kitchen extract cleaning
Before we fix a price, we need to know a few things. We check:
- Site rules, permits and inductions
- Where the site is and how we reach it
- How many systems or sites are involved
- How big the system is
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What to send for a quote
There’s no need for technical detail. Just send:
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide pictures of the system and the area around it
- Any previous report or certificate

Questions from Tewin Wood
Do you work overnight in Tewin Wood?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Which fire and rescue service is responsible for Tewin Wood?
Fire safety enforcement in Tewin Wood is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How much does kitchen extract cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Do I have to clean my extract to TR19 by law?
No law names TR19 directly, but the responsible person still has a legal duty under the Fire Safety Order 2005. Insurers, fire officers and EHOs look to TR19 as the standard, and many policies require it.
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.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then call 0345 646 2711, or email photos.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What is 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.
Aftercare tips
After the visit, a few habits help the work last:
- Keep the extract on whenever the range is lit
- Clean the grease filters regularly between TR19 cleans
- Keep to the recommended cleaning interval
- Refit filters properly after cleaning
The kitchen is left clean and ready for the next service. Grease and dirty water are collected and taken off site, so you can start cooking as normal.
Stick to the cleaning interval on the certificate. BESA guidance links the minimum interval to daily cooking hours, so a change in hours may mean a change in interval, and grease readings will show it.
Part by part
Extract fan and discharge
Some systems have attenuators to cut noise, and they hold grease. We clean what can be reached and note anything that cannot.
Schools, hospitals and care homes
School kitchens can look lightly used but still need a TR19 clean at least every 12 months under BESA guidance. School holidays are an easy time to do it.
