Why act early in Potters Bar
Grease left in a duct in Potters Bar hardens over time. It bakes into a hard layer that takes far longer to remove, so the later the clean, the bigger the job. With a fire risk assessment or inspection due, getting the work done first puts you on the front foot.
No two sites are the same, 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.

Ductwork cleaning in Potters Bar, done properly
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. We map the route during the survey and finds every access point before we quote. We are often asked to deal with fat dripping from the ductwork and gaps where access panels were never fitted, across attenuators, horizontal duct runs and multi-storey ducts.
Many kitchens in a town like Potters Bar were fitted into buildings built for something else, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct can’t be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What else we do in Potters Bar
Grease, kitchens and Potters Bar
The FSA’s data shows about 10 pubs, bars and clubs registered in Potters Bar and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Fire safety in Potters Bar falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from Hertsmere council inspect food businesses in Potters Bar. 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.
A kitchen near Potters Bar station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. A hall kitchen that only cooks for events, whether near St. Mary's Church or elsewhere in Potters Bar, still needs its extract cleaned, just less often.

Landlords, agents and facilities managers
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Between visits
After the visit, a few habits help the work last:
- Tell us if grease leaks from the ductwork
- Diarise the next duct clean
- Ask us about extra access panels where sections cannot be reached
- Do not 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.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
What we are called out for in Potters Bar
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should and it fills faster.
If you notice any of these, it’s worth a diagnosis:
- Grease leaking from duct joints
- Sections of duct with no access panels
- Stale grease odours from the duct
- Readings above 200 microns from a grease thickness test
A hospital like Barnet General Hospital, about 3.4 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Questions to ask before booking
- How they set the interval to the next visit
- What insurance they carry
- What’s included in the scope, part by part
- If they look at the system before pricing
What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours to more than one visit, depending on duct length and access. We arrive in Potters Bar once you’ve closed and leave the site ready for the morning.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Find the previous report, if there is one
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in
Ask for a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call 0345 646 2711, or send details by email.
Advice
When it’s something else
A few issues sit outside what this work can do:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- A duct that is too small or badly routed for the kitchen (a design issue)
- Fire dampers that do not close (they need testing and remedials)
If in doubt, call 0345 646 2711 or use the quote form and we’ll say what we think before booking.

Potters Bar questions
Do you clean school canteen extracts around Potters Bar out of term?
Yes. The holidays are the usual time for school work. There are about 13 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Potters Bar. Booking early in the term gives the best choice of holiday dates.
Who would carry out a food hygiene inspection at a kitchen in Potters Bar?
Kitchens in Potters Bar are inspected by Hertsmere council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Will the duct clean disrupt the kitchen?
When the kitchen is closed. Long ducts can be split across visits, with the kitchen ready to cook each morning.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
How long will the duct clean take?
Duct length, access and grease levels all affect it. Typically it takes from a few hours to more than one visit, depending on duct length and access.
Are you fully insured?
Yes. We are fully insured, and the details are available on request.
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
