FAQs for Test Valley
Can you come to Test Valley after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Test Valley keeps running as normal. Tell us your opening hours when you ask for a quote.
Which council inspects kitchens in Test Valley?
The local authority for Test Valley is Test Valley council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We don’t leave it behind.
Do you work in Test Valley?
Yes. Our technicians work in Test Valley, as part of our area across London and the South East.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and where several people have control, each can have duties. If you’re not sure, check your lease and fire risk assessment.
Will we have to shut during the visit?
Not usually. Booking the work out of hours means the site can carry on as normal. Bigger sites can be done in stages to keep things running.
Grease filter exchange for kitchens and businesses in Test Valley
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork, but some grease still passes through as vapour. That’s why the whole system still needs cleaning to TR19 at the right interval. If you have grease left in baffles after washing and poor airflow through the filters, we can help, from school and hospital kitchens, mesh filters and baffle filters onwards.
Somewhere as small as Test Valley, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
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.

Common problems we fix in Test Valley
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
Clients typically contact us when they notice one of these:
- Filter washing that keeps being missed
- Filters that come out of the sink still dirty
- Gaps where filters have been removed
- Smoke and heat lingering under the hood

How we price grease filter exchange
Sites vary more than people expect. The main factors:
- The condition of the system
- Travel, parking and unloading
- The scale of the work
- A single visit or a regular plan
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.
Helping us quote
When you call or email, these details help:
- Any access panels or hatches you can see
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Leave it or put it right?
Clogged filters choke the extract. The kitchen gets hotter and smokier, and the fan works harder to pull air through. A regular exchange keeps the airflow where it should be. Systems in rural buildings are often out of sight and out of mind.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before any work starts.
Why us?
- Fixed quotes from a survey or pictures
- Fully insured
- A written report with pictures after each visit
- Work around your opening hours, with 24/7 emergency cover

Different parts, different methods
School, care home and staff kitchens
A longer exchange interval may suit lighter cooking. We agree the schedule to match.
Canopy filter housings
Every exchange includes a check of how the filters sit, because gaps let grease through.
Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Between visits
Good habits slow the build-up between visits. A few tips:
- Look out for drips from the canopy
- Keep filter exchange and TR19 cleaning on the same plan
- Clear anything stored on or near the canopy
- Never leave gaps in the filter bank
Once the clean filters are in, the kitchen can cook straight away. The dirty set leaves with us for cleaning.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.
The process
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from a few minutes to an hour or so, depending on the number of filters. For a village or hamlet like Test Valley, tell us about narrow lanes, gates and parking when you book.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Before we arrive
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
How to get a quote
To get a fixed quote, ring 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
