About our TR19 inspection in Rowly
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. If you have ductwork where grease may be over the TR19 limits and sites with gaps in their extract records, we can put it right.
For a kitchen in or near Rowly, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes a morning or less for one kitchen, more where there are several systems. Visits to a village like Rowly are booked in advance, at a time that suits whoever runs the site.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
How to prepare
- Tell us where we can park and unload
- Agree a time when the area can be out of use
- Find the previous report, if there is one
Getting a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What TR19 inspection looks like in Rowly
There are about 16 cafés, restaurants and staff canteens and about 4 takeaways within roughly a mile and a half of the centre of Rowly, according to the Food Standards Agency’s register. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Surrey Fire and Rescue Service covers Rowly. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Rowly, food businesses are inspected by environmental health officers from Waverley council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Milford Hospital is the nearest hospital to Rowly, about 5.2 miles west. If your kitchen is in a listed or historic building, like the houses around Rowly (Chilworth Manor is about 4.3 miles north), fitting access panels needs care.
Rowly is about 7 miles south-east of Guildford, in Surrey. Rowly gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Rowly is one of 395 places in Surrey we cover for TR19 inspection. Guildford is in our area too, about 7 miles from Rowly.
All of GU6 and GU5 is covered for TR19 inspection, from the main roads to the quietest streets. Streets in the area include Guildford Road, Strathavon Close and Smithwood Avenue, and we cover them all for TR19 inspection. Close by, we work in Stroud Common (1 mile north), Elmbridge Village (1 mile south), Grafham (2 miles west), Shamley Green (2 miles north-west) and Birtley Green (2 miles north-west). Further out, we also cover Guildford (7 miles north-west), Woking (11 miles north), Camberley (15 miles north-west), Horley (15 miles east), Farnham (13 miles west) and Reigate (14 miles east).
Around Rowly
We work in commercial kitchens and buildings around Cucknell's Wood. Rowly’s nearest station is Chilworth station, roughly 3.9 miles north of the centre. Well-known places in the area include Milford Hospital (5.2 miles west). For a walk, there’s Lower Lake and St Martha's Hill and Colyer's Hanger.
What affects the cost of TR19 inspection
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Access, including roofs, risers and ceiling voids
- Parking and loading at the site
- Whether several sites go on one quote
- Site rules, permits and inductions
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.
Helping us quote
When you call or email, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is

What we’re called out for in Rowly
Menus, opening hours and cooking styles change over time, and more frying or longer hours mean more grease. The old cleaning schedule may not match the kitchen any more.
Clients typically contact us when they notice something like this:
- Kitchens whose menu or hours have changed
- Missing TR19 certificates or history
- Extracts that have never been grease tested
- An insurer’s request for a TR19 audit
For schools such as Glebelands School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Different parts, different methods
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
Horizontal duct runs
If a run has no access panel, we note it so it can be fixed before the clean.
Aftercare tips
Once we have finished, these simple steps help:
- Mention new equipment or longer hours at the next test
- Keep to the recommended interval
- Keep grease filters clean and fitted properly
- Have the latest report ready for insurance renewals
Where sections couldn’t be reached, the report says where access panels would help. With panels fitted, the next clean can cover every section.
Fit access panels where the survey finds sections cannot be reached, so grease is not left building in hidden parts.
Rowly: your questions answered
Can the work in Rowly be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Rowly does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you do school kitchen extract cleaning in Rowly in the summer holidays?
Yes. The holidays are the usual time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Rowly. Tell us your holiday dates and we will book the visit for when the site is empty.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.
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 types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.

In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
