How we handle ductwork cleaning in Newnham
Ductwork in Newnham is cleaned the same thorough way as everywhere else we work: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and photos complete the record. We are often asked to deal with duct runs that can’t be reached and ductwork that has never been cleaned, across access panels, attenuators and vertical risers.
Somewhere as small as Newnham, 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.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What ductwork cleaning can’t fix

- Duct sealed behind fixed ceilings or walls
- A worn-out fan that needs replacing

Your quote is based on your site. We consider:
- Working hours and out-of-hours timing
- Any permits to work or inductions
- How many systems or sites are involved
- Whether it’s a one-off visit or part of a schedule
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.
What we need to know
There’s no need for technical detail. Just send:
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings

- Your opening hours and when the area is out of use
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Why it’s worth doing now in Newnham
Booking the duct clean in Newnham now keeps it a planned job. The work takes from a few hours to more than one visit, depending on duct length and access, and we work evenings, overnight and weekends. Somewhere as small as Newnham, losing a kitchen or building to a fault is felt by everyone who uses it.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.

How it works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and leave you the report. On site, the work takes a few hours for a short run, longer for long runs and tall risers. In a small place like Newnham, the journey is planned ahead and the visit arranged around the site’s hours.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Heavy deposits come out by hand, then each section is degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Before we arrive
- Tell us where we can park and unload
- Clear the space around the work

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

When to call us in Newnham
A greasy duct is a fire path, in Newnham as anywhere. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
If you notice any of these, it’s worth a diagnosis:
- Grease pooling at the foot of the riser
- A duct nobody has opened in years
- Smells of old cooking grease from the ductwork
- Duct runs that can’t be reached
Hinxworth Place, about 1.4 miles north, is one of the historic houses near Newnham; if you run event catering at a venue like that, cleans can be booked between functions.

FAQs for Newnham
Who carries out food hygiene inspections in Newnham?
In Newnham, it’s North Hertfordshire 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 work in villages like Newnham?
Yes. Villages and rural sites across the South East are part of our work, Newnham included. Photos of the system and directions to the site help us plan the visit.
What does ductwork cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What’s involved in cleaning extract ducts?
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.
Can you clean ductwork with no access panels?
Without a way in, a section cannot be cleaned properly. Those parts are listed, and we can install panels so they’re reached next time.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.
How the job changes from site to site
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
Horizontal duct runs
Horizontal runs carry the extract along ceilings and through voids. Grease drops out of the slowing air along them, and we clean them section by section through access panels.
Newnham kitchens: local notes
There are about 5 cafés, restaurants and staff canteens and about 8 sandwich bars and takeaways within about 1.5 miles of central Newnham, according to the Food Standards Agency’s register. Behind every canopy among them is a run of ductwork that collects grease out of sight. Food hygiene inspections in Newnham are the job of North Hertfordshire council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Hertfordshire Fire and Rescue Service covers Newnham. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Newnham is Fairfield Hospital, about 3 miles south-west. Volunteers running a hall kitchen near Church of St Vincent, or anywhere in Newnham, may not know when the extract was last cleaned, and a grease test settles it.
