How we handle TR19 inspection in Durley Street
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. If you have kitchen extract systems with no recent grease readings and surveys needed before quoting a full clean, we can help, from post-clean checks, pre-clean surveys and access surveys onwards.
For a kitchen in or near Durley Street, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Common questions in Durley Street
Which fire authority looks after Durley Street?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Durley Street. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you work at weekends in Durley Street?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Durley Street needn’t be disturbed. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
What is a WFTT or DTT grease test?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
How often should grease be tested?
It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
How long does grease testing take?
Expect it to take a couple of hours for a typical kitchen extract system. We fit it around when the kitchen is closed or quiet.
Is a quote from pictures possible?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If pictures are not enough, we will survey first.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.
At what point does grease need cleaning?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning straight away.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a morning or less for one kitchen, more where there are several systems. Visits to a village like Durley Street are booked in advance, at a time that suits whoever runs the site.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
Getting a quote
To get a fixed quote, ring 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will typically have a quote within one working day.

What we are called out for in Durley Street
TR19® is the benchmark that insurers, fire officers and EHOs refer to. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
Most sites get in touch when they notice one of these:
- Sections of duct that can’t be reached
- Extracts that may be over the 200 micron mean
- Pre-clean surveys before a first TR19 clean
- Post-clean verification after another contractor’s clean
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Moorgreen Hospital is the nearest hospital to Durley Street, about 3.9 miles south-west.

- What records you will receive afterwards
- Whether the figure could change on the day
- What happens if part of the system cannot be accessed

Why choose Duct Doctor in Durley Street
- Fully insured
- A single point of contact for sites across the South East and London
- Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
- CHAS and SafeContractor accredited, with ISO 9001
Between visits
After the visit, a few habits help the work last:
- Keep canopy edges and gutters wiped down
- Mention new equipment or longer hours at the next test
- Never cook with filters missing
- Do not box in or cover duct access panels
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
Part by part
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
Filters can look fine while the plenum behind them is heavily coated. That’s why we test behind them.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
