About our TR19 inspection in Naphill
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, photos and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. The work covers deposit thickness tests, access surveys and wet film thickness tests, and people most often call us about heavy grease suspected in the plenum or ducts and extracts that have never been grease tested.
Work in a small place like Naphill starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too in Naphill and across Buckinghamshire. Work can be phased by floor, building or site around the people who use them.
What we are called out for in Naphill
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Look out for any of the following:
- An insurer’s request for a TR19 audit
- Parts of the system left out of past cleans
- Systems cleaned on a calendar with no measurements
- Kitchens whose menu or hours have changed
If you look after a school kitchen, at a school such as Naphill and Walters Ash School or anywhere near Naphill, the holidays are the usual time for a TR19® clean.
Questions to ask before you book
- When the next visit should be, and why
- If the quote is a fixed price or an estimate
- What records you’ll receive afterwards
- Whether VAT is included
When something else is needed
We’d rather tell you now than book work that will not help, so here are the limits:
- Fire safety duties beyond the extract system
- Sections with no access, until panels are fitted
- Removing the grease, which is a separate clean
If you’re not sure, just call 0345 646 2711, or email photos and we will give you a straight answer before you book.

Fixed quotes for TR19 inspection in Naphill
The price is fixed before any work begins. It’s based on:
- The condition of the system
- The times the site is available
- Whether several sites go on one quote
- A single visit or a regular plan
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
- The postcode and the type of business
- A few general shots of the system
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
When your team notices a problem 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 give you a fixed quote.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Wipe the canopy surfaces regularly
- File every inspection report with your certificates
- Keep the route to access panels clear
- Never cook with filters missing
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Keep certificates, reports and readings in one place so the history is easy to show.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The timing of a visit to Naphill is set by you, and the travel is our side of the planning.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Before we arrive
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
Getting a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.

Naphill: your questions answered
Is Naphill within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Which council inspects kitchens in Naphill?
That is Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Naphill. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Is TR19 a legal requirement?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurance policies also require TR19 adherence.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What happens on a pre-clean survey?
We look at the system from canopy to discharge, take grease readings and check access. From it, we plan the clean and quote a fixed price.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What if parts of the system cannot be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
Grease, kitchens and Naphill
The FSA’s food hygiene register includes about 5 bars, pubs and nightclubs across Naphill 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. It’s Buckinghamshire council that sends environmental health officers to food businesses in Naphill. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Naphill sits within the area of Buckinghamshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Where a hall near Church of St Botolph, or anywhere in Naphill, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Historic houses near Naphill, such as Hughenden Manor about 1.5 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Naphill is about 3 miles north-west of High Wycombe, in Buckinghamshire. We carry out TR19 inspection for commercial premises of every kind in Naphill and the rest of Buckinghamshire. We cover 263 places across Buckinghamshire, from busy centres to quieter spots. There’s also a page for Reading, about 17 miles away.
Here we cover the HP14 postcode area for TR19 inspection. If you need TR19 inspection at premises on Christopher Close, Main Road and Purssells Meadow or a nearby road, we can help. Nearby, we also carry out TR19 inspection in Walter's Ash (1 mile north-west), Lower North Dean (1 mile north-east), Hughenden Valley (1 mile east), Upper North Dean (1 mile north) and Downley (1 mile south). Within a short drive, we also cover Aylesbury (11 miles north), High Wycombe (3 miles south-east), Chesham (8 miles north-east), Marlow (6 miles south), Amersham (8 miles east) and Beaconsfield (7 miles south-east).
