Ashridge ductwork cleaning
Professional ductwork cleaning in and around Ashridge, timed so the site keeps working and finished with a written report and pictures.
- Gaps where access panels were never fitted
- Fat dripping from the ductwork
- Duct runs with no cleaning record
Between visits
Aftercare is simple, and it makes the next visit easier:
- Flag drips from the duct right away
- Consider fitting panels where the report shows gaps
- Leave a way through to the access panels
- Don’t switch the extract off early
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
How we handle ductwork cleaning in Ashridge
Ductwork in Ashridge is cleaned the same thorough way as everywhere else we work: we test the grease first, remove thick deposits by hand and degrease what’s left. Post-clean readings and photos complete the record. Typical jobs include a rancid smell from the extract duct and a duct clean needed for an insurer, across access panels, horizontal duct runs and attenuators.
Somewhere as small as Ashridge, 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, whatever the size of the place.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Ashridge
Environmental health officers from Dacorum council inspect food businesses in Ashridge. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after photos from each clean are a simple way to show the extract is in hand. At about 29 miles from central London, Ashridge sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hemel Hempstead Hospital is the nearest hospital to Ashridge, about 5.1 miles south-east.
Ashridge is about 3 miles north of Berkhamsted, in Hertfordshire. Whatever kind of site you run in Ashridge, we can take on ductwork cleaning. We can work out of hours so the site keeps running.

What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes a few hours for a short run, longer for long runs and tall risers. Pictures of the system and its access let us plan the work in Ashridge before we set off.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend

Related advice
What your team can do, and what needs us
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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Common questions in Ashridge
Do you do school kitchen extract cleaning in Ashridge in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ashridge. Just call us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Which fire service covers Ashridge?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Ashridge. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How is kitchen extract ductwork cleaned?
We open each access panel and clean the section it reaches. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Is a quote from photos possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we’ll say so.
How often should kitchen ducts be cleaned?
It follows the same interval as the whole extract, ranging from 3-monthly to 12-monthly. Readings tell you if it needs to be more often.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How we price ductwork cleaning
Sites vary more than people expect. The main factors:
- One-off work versus a regular cycle
- The number of sites or systems
- Where the site is and how we reach it
- The size of the system
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711, or email photos, and we will talk you through it.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- The postcode and the type of business
To help us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, ring 0345 646 2711, or email photos.
Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Do you need ductwork cleaning in Ashridge?
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
These are the problems we see most often:
- A rancid smell from the extract duct
- Grease pooling at the foot of the riser
- High readings at a recent grease test
- A duct clean needed for an insurer
In and around Ashridge, every reachable section of the extract is cleaned, and anything we cannot reach goes on the report.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- Whether VAT is included
- What hours they’ll be on site
- When the next visit should be, and why
What happens if it’s left?
TR19® is not law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. In a place like Ashridge, ductwork and fans are easy to forget until something goes wrong.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before we start.
