Questions from Blacknest
Can the work in Blacknest be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Blacknest keeps running as normal. Your opening times are the first thing we ask for.
Who inspects food businesses in Blacknest?
In Blacknest, it’s East Hampshire council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you cover Blacknest?
Yes. Our area takes in London and the counties of South East England, and that includes Blacknest.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
How often should a kitchen extract be cleaned?
BESA guidance sets minimums by daily cooking hours: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Measured grease levels set the real interval.
Why do insurers care about extract cleaning?
Many insurers ask for proof of regular cleaning to TR19, and many policies require it. Without proof, a claim can be refused or reduced, so it’s worth checking your policy wording.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
How much does kitchen extract cleaning cost in Blacknest?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will typically reply within one working day.
TR19 kitchen extract cleaning in Blacknest
We treat an extract system much as a doctor treats a patient: diagnose with a survey, treat with a thorough clean, then sign it off. That clean bill of health comes as a TR19 certificate and a photo report, issued through the BESCA Vent Hygiene Elite portal. We are often asked to deal with poor airflow at the canopy and a kitchen with no current TR19 certificate, on plenums and filters, horizontal duct runs and extract fans. Searching for commercial kitchen extraction cleaning in Blacknest? Duct Doctor has covered London and the South East since 2009, with a certificate and photo report after every clean.
Each job starts with a look at where grease has built up: grease readings at set points tell us where the heaviest deposits are, and the same readings after the clean show the result.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What kitchen extract cleaning looks like in Blacknest
Food hygiene inspections in Blacknest are the job of East Hampshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. About 40 miles out from central London, Blacknest is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
For kitchens close to Bentley (Hampshire) station, where the day often starts early and ends late, the extract can be cleaned overnight. Healthcare kitchens, like those at hospitals such as Chase Community Hospital (about 4.7 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. Farnham Castle, about 4.1 miles north-east, is one of the historic houses near Blacknest; if you run event catering at a venue like that, cleans can be booked between functions.
Blacknest is about 4 miles south-west of Farnham, in Hampshire.

Different parts, different methods
Canopy and plenum
Grease meets the system first at the canopy and the plenum behind the filters. We clean both inside and out, with the filter housing cleaned too.
Schools, hospitals and care homes
In a care home or hospital, the kitchen may cook every day of the year. We plan the clean around meal times and work in a contained, tidy way with as little disruption as possible.
Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Book the next clean before the date on the report
- Keep grease collection points emptied
- Wash or exchange the filters often
- Make sure every filter is fitted before cooking
If we couldn’t get into part of the duct, the report says so plainly. A TR19 report should record what wasn’t cleaned as well as what was, and we can fit access panels so it’s reached next time.
Run the extract whenever the kitchen is cooking. Switching it off early leaves vapour to settle on the canopy and plenum, and the next clean has more to do.
What a clean will not put right
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- A broken extract fan that will not run
- Fire dampers that won’t close (that needs damper testing and remedials)
- An undersized canopy or fan
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.

Fixed quotes for kitchen extract cleaning in Blacknest
The quote reflects the site in front of us. We consider:
- Parking and loading at the site
- Whether we need access equipment or extra panels
- How big the system is
- Whether several sites go on one quote
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- The postcode and the type of business
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
