Questions from Dorking
Which fire authority looks after Dorking?
It’s Surrey Fire and Rescue Service, which covers Dorking. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can the work in Dorking be done at night or at weekends?
Yes, we can come after you close and finish before you open. That way a site in Dorking does not have to lose a day’s trading. Just ring 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Can you price the work without visiting?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
How much does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
When should we have our next grease test?
Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
TR19 inspection in Dorking
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. The work covers post-clean checks, wet film thickness tests and deposit thickness tests, and common reasons people get in touch are post-clean verification after another contractor’s clean and missing TR19 certificates or history.
Kitchens in towns like Dorking are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Sections we cannot reach are listed on the report, and access panels can be added.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
We also work for facilities teams across offices, schools and healthcare across Surrey. Work can be phased by floor, building or site to keep disruption down.
Keeping the system healthy
So the system stays in good health:
- Flag oily drips near the extract
- Never cook with filters missing
- File every inspection report with your certificates
- Send TR19 audit reports to your insurer on request
Keep the verification report next to the certificate it relates to. The pair gives a clear record of the clean and the check.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
TR19 inspection around Dorking
Food Standards Agency data counts about 59 cafés, restaurants and staff canteens and about 10 takeaways and sandwich shops in Dorking and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. In Dorking, food businesses are inspected by environmental health officers from Mole Valley council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Surrey Fire and Rescue Service covers Dorking. 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.
School kitchens, at schools like St Paul's CofE (Aided) Primary School for example, are usually cleaned in the holidays so no lunches are lost. If you cook for passing trade around Dorking Deepdene station, the extract can be cleaned between your last and first customer. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Headley Court is the nearest hospital to Dorking, about 4.8 miles north-east.

- We note where access panels are and where more are needed.
- Grease readings are taken and photos recorded.
- You get a report and a fixed quote for the clean.

How the job changes from site to site
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and photos are taken in the plenum as part of every survey.
Extract fan and discharge
Grease on the fan adds to wear. Readings show if it needs attention before the next clean.
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Leave it or put it right?
Without readings, you are guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. Before an inspection or an insurer’s visit in Dorking, it helps to have up-to-date records.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
What you get with us
- Fully insured
- Evenings, overnight and weekends, plus 24/7 emergency callout
- A single point of contact for sites across the South East and London
- Trading since 2009

What affects the quote in Dorking
The price is fixed before any work begins. It takes into account:
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- The scale of the work
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
