TR19 inspections and grease testing in Chesham, Buckinghamshire
TR19 inspection in Chesham from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Heavy grease suspected in the plenum or ducts
- Missing access panels found on survey
- Surveys needed before quoting a full clean
How the visit works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, 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. Three things shape a visit in Chesham: when you’re closed, where we can park and how we get to the system.
- The visit is arranged for when the kitchen is not busy.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Photos are taken at each point, and access gaps noted.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
- Mention any parking or loading restrictions
Getting a quote
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

TR19 inspection in Chesham
Before any clean in Chesham, we survey the canopy, plenum, filters, ducts, fan and 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 have an insurer’s request for a TR19 audit and missing TR19 certificates or history, we can put it right, from access surveys, post-clean checks and deposit thickness tests onwards.
In a town like Chesham, most of the kitchen extracts we’re asked about belong to restaurants, cafés, pubs, takeaways and school or care home kitchens. Whatever the kitchen, the canopy, filters, duct and fan all collect grease.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

FAQs for Chesham
Can the work in Chesham be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Chesham needn’t be disturbed. Just call 0345 646 2711 or email us with your opening times and we’ll plan around them.
Can school kitchens in Chesham be cleaned in the holidays?
Yes. The holidays are the usual time for school work. With about 11 schools and colleges on the FSA’s register within roughly a mile and a half of Chesham, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711 or email us, and we’ll fit the work in.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
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.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What does a pre-clean survey involve?
We survey, measure and photograph the system first. We can work from photos and details, or visit, as suits the job.
At what point does grease need cleaning?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. We show your readings against those figures.
Do you work with multi-site operators?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
TR19 inspection in Chesham: the local picture
Food Standards Agency records include about 10 pubs, bars and clubs across Chesham and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Environmental health officers from Buckinghamshire council inspect food businesses in Chesham. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Chesham is Buckinghamshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
For schools such as Elmtree Infant and Nursery School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Healthcare kitchens, like those at hospitals such as Amersham Hospital (about 3.4 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Do you need TR19 inspection in Chesham?
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
Clients typically contact us after spotting something like this:
- Kitchen extract systems with no recent grease readings
- Systems that need surveying before cleaning
- Ductwork where grease may be over the TR19 limits
- Kitchens whose menu or hours have changed
If you run catering at a historic house or estate in the area (Cholesbury Manor House is about 3.5 miles north-west), event kitchens in older buildings often have awkward duct runs that need planning.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Clean or swap grease filters as often as the kitchen needs
- Keep TR19 certificates, readings and reports together
- Mention new equipment or longer hours at the next test
- Wipe the canopy surfaces regularly
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
How the job changes from site to site
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. We take readings there and photograph it as part of every survey.
Why act early in Chesham
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, so the clean covers the whole system. An inspector or insurer will want to see recent records, so it makes sense to have them ready.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
