Common questions in Rosehill
Do you do school kitchen extract cleaning in Rosehill in the summer holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 36 schools and colleges with food registrations within roughly a mile and a half of Rosehill. Booking early in the term gives the best choice of holiday dates.
Which fire and rescue service is responsible for Rosehill?
Fire safety enforcement in Rosehill is handled by London Fire Brigade. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
Do you work out of hours?
Yes, and that is how we prefer to work. The visit is timed for when the area isn’t in use, whether that is late evening, overnight or a weekend.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Can you verify a clean after it’s been done?
We visit after a clean, take readings at set points and photograph the system. Any areas that weren’t cleaned properly are flagged.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Do you work in Rosehill?
Yes. We cover Rosehill and the rest of Greater London, within our South East and London area. To book, give us a ring on 0345 646 2711 or send us an email.
How we handle TR19 inspection in Rosehill
If you’ve taken over a kitchen in Rosehill and don’t know when the extract was last cleaned, an inspection is the place to start. We survey the system, measure the grease and tell you what needs doing, before any cleaning is booked. The work covers pre-clean surveys, post-clean checks and wet film thickness tests, and the jobs we see most are surveys needed before quoting a full clean and cleaning intervals that may not suit the kitchen.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Rosehill, that normally means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What happens if it’s left?
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 Rosehill a current picture. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.
What you get with us
- Every visit written up, with pictures
- One contact for all your sites in London and the South East
- We diagnose before we treat
- Fixed quotes from a survey or pictures
The process
We turn up 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 before any work starts, and floors and nearby surfaces are sheeted. The work itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Rosehill.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Move anything stored near the system
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
When something else is needed
We will not sell you work that does not address the problem, so these are the things it will not cover:
- The grease itself, which needs a full or spot clean
- The responsible person’s own fire risk assessment
- Parts of the duct nobody can reach yet
If you are not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer.
Where we work
- Post-clean checks
- Insurer audits
- Access surveys
- Wet film thickness tests
- Deposit thickness tests
- Pre-clean surveys

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Keep the route to access panels clear
- Clean or swap grease filters as often as the kitchen needs
- Send TR19 audit reports to your insurer on request
- Tell us if menus or opening hours change
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Keep certificates, reports and readings in one place so you can produce them quickly.
Part by part
Canopy and plenum
We look over the canopy, inside and out, with readings where grease collects.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
Kitchen extracts in Rosehill
Look up Rosehill on the FSA’s food hygiene register and you will find about 164 restaurants, cafés and works canteens and about 93 takeaways within roughly a mile and a half of the centre of Rosehill. Each kitchen extract among them can be measured for grease to set the right cleaning interval. The fire and rescue service for Rosehill is London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. London jobs usually start after the last service, with loading and roof access agreed with the building first.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Rosehill is St Helier Hospital, about less than half a mile south. Where a hall near St Peter's Church, or anywhere in Rosehill, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like Tweeddale Primary School, an extract clean fits neatly into a half-term or summer break.

What affects the quote in Rosehill
We quote each job individually. This is what makes a difference:
- Whether several sites go on one quote
- Any permits to work or inductions
- Where the site is and how we reach it
- A single visit or a regular plan
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or email photos.
