TR19 inspection in Chandler's Cross
A pre-clean survey is the diagnosis, and the clean is the treatment. Readings, pictures and notes on access are gathered from end to end, so the quote and the clean fit the real system. If you are dealing with systems cleaned on a calendar with no measurements and sections of duct that can’t be reached, we can put it right.
Work in a small place like Chandler's Cross 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.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the job changes from site to site
Extract fan and discharge
A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. Readings and photos are taken in the plenum as part of every survey.
The process
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. For a village or hamlet like Chandler's Cross, tell us about narrow lanes, gates and parking when you book.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Chandler's Cross kitchens: local notes
The FSA’s food hygiene register shows about 7 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Chandler's Cross. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Chandler's Cross 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. Food hygiene inspections in Chandler's Cross are the job of Three Rivers council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
If your kitchen is in a listed or historic building, like the houses around Chandler's Cross (Chenies Manor House is about 3.2 miles west), fitting access panels needs care. If you look after a school kitchen, at a school such as York House School or anywhere near Chandler's Cross, the holidays are the usual time for a TR19® clean.

FAQs for Chandler's Cross
Do you do school kitchen extract cleaning in Chandler's Cross in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Chandler's Cross, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711, or email photos, and we will fit the work in.
Can you come to Chandler's Cross after we close?
Yes, nights and weekends are routine for us. It means the site in Chandler's Cross keeps running as normal. Tell us your opening hours when you ask for a quote.
What is post-clean verification?
We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What does a pre-clean survey involve?
It’s a look at the whole extract before it’s cleaned, with readings and pictures. The survey can be done from pictures and details or on site, whichever suits the system.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What grease levels does TR19 allow?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, with 500 microns or more anywhere needing immediate spot cleaning.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.

How we price TR19 inspection
Sites vary more than people expect. The main factors:
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- Parking and loading at the site
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 us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
Asking for a quote
We can often survey from pictures. Try to include:
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- Any access panels or hatches you can see
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, call 0345 646 2711 or drop us a line.
Do you need TR19 inspection in Chandler's Cross?
Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
Common reasons sites call us include:
- Insurance renewals needing proof of TR19 cleaning
- Missing access panels found on survey
- Extracts that may be over the 200 micron mean
- Systems cleaned on a calendar with no measurements
If you run catering at a healthcare site, such as a hospital like Watford General Hospital about 2.9 miles south-east, the extract may need cleaning more often than a part-time kitchen.
What your quote should include
- Whether a written report and pictures are included
- Whether the quote shows VAT
- Whether the figure could change on the day
- Whether they’re fully insured
Honest limits
We will always give you a straight diagnosis, so here’s what TR19 inspection won’t do:
- Mechanical faults in the extract
- The responsible person’s own fire risk assessment
- Removing the grease, which is a separate clean
Not sure which it is? You can call 0345 646 2711 or send us an email and we will tell you honestly before you book.
