Longwick ductwork cleaning
Ductwork cleaning in Longwick from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.

- A duct clean needed for an insurer
Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Don’t switch the extract off early
- Ask us about extra access panels where sections can’t be reached
- Keep your cleaning records together
- Keep to the interval on the report
You’ll have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Keep the fan on throughout service. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
Ductwork cleaning in Longwick, done properly
Not sure when the ductwork was last cleaned? A few details about the system are a good start when you ring 0345 646 2711 or use the quote form, and a fixed price will follow, usually within one working day. The work covers attenuators, access panels and horizontal duct runs, and the jobs we see most are grease leaking from duct joints and thick crusts of old grease along the duct.
In a smaller place like Longwick, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so cleaning is planned around how much it cooks and what the readings show.
The sign-off is always in writing: a dated report with pictures 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.

Why deal with it now?
A dirty duct is something insurers ask about. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. A certificate that covers the ductwork is what they want to see. It’s better to plan the work at a site near Longwick than wait for a failure.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

Longwick: your questions answered
Who enforces fire safety at workplaces in Longwick?
Longwick is in the area of Buckinghamshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who carries out food hygiene inspections in Longwick?
In Longwick, it’s Buckinghamshire 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.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
When is the ductwork cleaned?
When the kitchen is closed. Long ducts can be split across visits, with the kitchen ready to cook each morning.
What paperwork do you give after a duct clean?
A photo report, with readings and before and after photos, plus a TR19 certificate for a full system clean. The report says when the next clean is due.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How often does extract ductwork need cleaning?
It depends mostly on daily cooking hours. Heavy use of 12 to 16 hours a day means at least every 3 months, while lighter use can go longer.
Is a quote from photos possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from a few hours to several visits, depending on the length of duct. In a place like Longwick, we fit the visit around your hours.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and photos go into the report, with any unreachable section listed.
How to prepare
- Tell us about site rules, permits or sign-in
- Tell us where we can park and unload
- Arrange a key holder or contact on site
How to get a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

What affects the cost of ductwork cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- The number of sites or systems
- The times the site is available
- The scale of the work
- Site requirements such as sign-in and permits
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
Asking for a quote
We can often survey from pictures. The most useful are:
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- The postcode and the type of business
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Kitchen extracts in Longwick
Food Standards Agency data counts about 12 restaurants, cafés and works canteens in Longwick and the streets around it, up to about 1.5 miles out. Behind every canopy among them is a run of ductwork that collects grease out of sight. Buckinghamshire Fire and Rescue Service covers Longwick. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In Longwick, food businesses are inspected by environmental health officers from Buckinghamshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Volunteers running a hall kitchen near Owlswick Chapel, or anywhere in Longwick, may not know when the extract was last cleaned, and a grease test settles it. A hospital like St John's Hospital, about 4.6 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
