TR19 inspection in Cottered, done properly
After a clean, post-clean verification checks the result, with new readings and photos of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. The work covers access surveys, post-clean checks and wet film thickness tests, and the jobs we see most are pre-clean surveys before a first TR19 clean and insurance renewals needing proof of TR19 cleaning.
For a kitchen in or near Cottered, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes a couple of hours for a typical kitchen extract system. We agree a date with you, plan the drive to Cottered and turn up when the site is quiet.
- 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.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Before we arrive
- Arrange a key holder or contact on site
- Clear loose items from the work area
- Dig out any earlier paperwork for the system
How to get a quote
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, give us a ring on 0345 646 2711 or email us.
Advice
Grease, kitchens and Cottered
Food hygiene inspections in Cottered are the job of East Hertfordshire council’s environmental health team. 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. Cottered sits within the area of Hertfordshire 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.
Term dates shape school work: for a school like Freman College, an extract clean fits neatly into a half-term or summer break.
Cottered is about 5 miles north-east of Stevenage, in Hertfordshire. Whatever kind of site you run in Cottered, TR19 inspection is something we can help with. We can work out of hours so the site keeps running. Across Hertfordshire, we cover 381 places, and Cottered is one of them. Chelmsford is in our area too, around 28 miles away.

When to call us in Cottered
Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.
Keep an eye out for these warning signs:
- Insurers asking for TR19 evidence
- Extracts that may be over the 200 micron mean
- Uncertainty over how often to clean
- Parts of the system left out of past cleans
If you run a church or community hall kitchen, near Parish Church of St John the Baptist or elsewhere in Cottered, its extract still collects grease from every lunch and event.

How the job changes from site to site
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that’s enough.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. We take readings there and photograph it on every inspection.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Cottered: your questions answered
Will you come out to Cottered?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Who carries out food hygiene inspections in Cottered?
In Cottered, it’s East Hertfordshire council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can the work be done while we’re closed?
Yes, and it’s often the best time. The visit is timed for when the area is not in use, such as late evening, overnight or a weekend.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
When should we have our next grease test?
Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where necessary. A fixed quote follows.
Honest limits
To be straight with you, there are a few things this work will not fix:
- Fan breakdowns, which need a repair visit
- Ductwork that was designed or installed badly
- Sections with no access, until panels are fitted
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.

Why it’s worth doing now in Cottered
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. An inspection now gives a site in Cottered a current picture. A fault that closes a site in a village like Cottered affects everyone who depends on it.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Why choose Duct Doctor in Cottered

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 need training, the right equipment and safe access. That is our job.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
