Sperberry Hill: your questions answered
Do you cover smaller places like Sperberry Hill?
Yes. Villages and rural sites across the South East are part of our work, Sperberry Hill included. A survey first, from photos or a visit, means we arrive with the right kit.
Which fire and rescue service is responsible for Sperberry Hill?
Sperberry Hill is in the area of Hertfordshire Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
How do you know if the ductwork needs cleaning?
Signs include grease dripping from joints, smells and a fan working harder, but measuring is the reliable way to know. Grease thickness testing shows exactly where the duct stands.
Are you insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
What paperwork do you give after a duct clean?
You get a photo report with before and after pictures, plus a TR19 certificate when the whole system is cleaned. Keep both in the maintenance log.
Is a quote from photos possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we normally come back within one working day. Some sites still need a visit, and we’ll say so.
When is the ductwork cleaned?
We plan the clean when you are not cooking. Overnight and weekend work is common, so no service is lost.
How is kitchen extract ductwork cleaned?
We survey the route, test the grease, then open the access panels. Each run and riser is scraped and degreased, and test again when we are done.
Ductwork cleaning for kitchens and businesses in Sperberry Hill
We treat ductwork like a doctor treats arteries: diagnose where grease has built up, clear it and confirm the result. Grease readings before and after give you the evidence, alongside before and after pictures. The work covers attenuators, bends and junctions and multi-storey ducts, and the jobs we see most are readings above 200 microns from a grease thickness test and grease seeping out of the duct seams.
In a small place like Sperberry Hill, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes anything from a few hours to several visits, depending on the length of duct. Somewhere as small as Sperberry Hill, the date and timings are agreed with you well before the day.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Horizontal runs and risers are then degreased by the method that suits the deposit.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
Before we arrive
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
Ask for a quote
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call 0345 646 2711 or use the quote form.

What a clean will not put right
Not every problem is solved by ductwork cleaning, and we’d rather say so up front. It will not put right:
- Duct sealed behind fixed ceilings or walls
- A failed fan motor at the end of the duct (a fan repair job)
- Undersized or badly laid-out ducts
If you’re not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.
Parts of the system we cover
- Bends and junctions
- Vertical risers
- Horizontal duct runs
- Attenuators
- Multi-storey ducts
- Access panels

Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Never cook with a filter missing
- Keep the fan on while anything is cooking
- Ask for a grease thickness test if the kitchen gets busier
- Keep your cleaning records together
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Waste grease and water are taken away.
Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
Different parts, different methods
Access panels
We can fit new access panels where the duct needs them, making future cleans more complete. The survey shows where they’re needed.
Bends and transitions
Transitions from the canopy spigot into the duct catch a lot of grease. We clean it from the canopy side or through a nearby panel.
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What ductwork cleaning looks like in Sperberry Hill
Food Standards Agency records include about 5 bars, pubs and nightclubs within roughly a mile and a half of the centre of Sperberry Hill. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Sperberry Hill get their food hygiene inspections from North Hertfordshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Sperberry Hill falls to Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
A hospital like Lister Hospital, about 2 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Knebworth House is about 4.1 miles south-east), access may need planning. Where a hall near Church of St Ippolyts (church of England), or anywhere in Sperberry Hill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What happens if it’s left?
