TR19 inspection in Clapham
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Testing is how you know where your system stands. If you have kitchen extract systems with no recent grease readings and systems that need surveying before cleaning, we can put it right, from deposit thickness tests, pre-clean surveys and insurer audits onwards.
For a kitchen in or near Clapham, 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.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Clapham kitchens: local notes
The FSA’s food hygiene register includes about 3 pubs, bars and clubs in Clapham and the streets around it, up to about 1.5 miles out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Clapham is West Sussex Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Kitchens in Clapham get their food hygiene inspections from Arun council. 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.
If your kitchen is in a listed or historic building, like the houses around Clapham (Ecclesden Manor is about 1.5 miles south-west), fitting access panels needs care. If you run catering at a healthcare site, such as a hospital like Zachary Merton Hospital about 3.4 miles south-west, the extract may need cleaning more often than a part-time kitchen.

What affects the quote in Clapham
Before we fix a price, we need to know a few things. We look at:
- Whether several sites go on one quote
- Parking and loading at the site
- Site rules, permits and inductions
- When the work can happen, such as evenings, overnight or weekends
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.
Asking for a quote
To help us quote quickly, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Photos of the system and how to reach it help us plan a visit to Clapham.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- The findings go into a report with readings, pictures and a recommended next clean.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
- Have your last certificate or report to hand

Common problems we fix in Clapham
Records can go missing when a business changes hands or contractors. Without them, nobody knows how much grease is in the system or when it was last cleaned.
These are the problems we see most often:
- Surveys needed before quoting a full clean
- Sites with gaps in their extract records
- Post-clean verification after another contractor’s clean
- Uncertainty over how often to clean
Church and community hall kitchens, near The Parish Church of St Mary or anywhere around Clapham, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- Whether the quote shows VAT
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
- When the next visit should be, and why
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Diary the next grease test and clean
- Clean or swap grease filters as often as the kitchen needs
- Keep TR19 certificates, readings and reports together
- Clean grease off the canopy between professional cleans
You get a report with the grease readings, where they were taken and pictures of each point. Keep it with your fire safety and TR19 records.
Keep certificates, reports and readings in one place so you can produce them quickly.
Part by part
Extract fan and discharge
The extract fan and its housing collect grease too. They’re included in the readings and pictures.
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, with testing showing whether more is needed.
Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
FAQs for Clapham
Do you cover smaller places like Clapham?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can you come to Clapham after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Is TR19 cleaning the law?
No. It’s the benchmark rather than the law. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
How long does grease testing take?
Expect it to take a morning or less for one kitchen, more where there are several systems. We fit it around when the kitchen is closed or quiet.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
How do you measure grease in a kitchen extract?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.
