Ductwork cleaning for kitchens and businesses in Broad Colney
Each extract duct we take on in Broad Colney goes through the full routine: readings at set points, heavy grease scraped out by hand, then degreasing to suit the deposit. Post-clean readings and photos complete the record. Typical jobs include readings above 200 microns from a grease thickness test and grease seeping out of the duct seams, across access panels, bends and junctions and multi-storey ducts.
In a small place like Broad Colney, 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.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep to the interval on the report
- Store the certificate with the fire risk assessment
- Flag drips from the duct right away
- Keep the fan on while anything is cooking
The report names every part of the duct that couldn’t be reached and why. You can then decide whether to have access panels fitted.
Have access panels fitted where sections cannot be reached. Grease you can reach is grease that gets removed.
When to call us in Broad Colney
Wherever the kitchen is, in Broad Colney or elsewhere, the duct fills in the same way: hours of cooking, the type of food and how well the filters are kept. BESA guidance sets minimum intervals of 3, 6 or 12 months depending on daily use.
These are the problems we see most often:
- Years of grease along the duct floor
- A rancid smell from the extract duct
- Gaps where access panels were never fitted
- Grease leaking from duct joints
If you look after a school kitchen, at a school such as Saint Bernadette Catholic Primary School or anywhere near Broad Colney, the holidays are the usual time for a TR19® clean.
Before you book anyone
- Proof of accreditation you can verify
- Proof of insurance
- What happens if part of the system cannot be accessed
- Whether the price is fixed
Why act early in Broad Colney
TR19® isn’t 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 small place like Broad Colney, a system that fails can take a site out of use.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Parts of the duct with no way in
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- Fire dampers that do not close (they need testing and remedials)
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly.

Broad Colney: your questions answered
Which fire authority looks after Broad Colney?
It’s Hertfordshire Fire and Rescue Service, which covers Broad Colney. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can school kitchens in Broad Colney be cleaned in the holidays?
Yes, out-of-term visits are normal for schools. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Broad Colney, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
How long does ductwork cleaning take?
It depends on the length of the duct, the number of access panels and how much grease there is. As a guide, it takes from a few hours to more than one visit, depending on duct length and access.
How much does ductwork cleaning cost in Broad Colney?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711 or email us and tell us about the site and its opening hours.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
How do you clean inside the ductwork?
Through access panels along the duct. Heavy grease is scraped out by hand, then the surfaces are degreased with a method that suits the deposit, such as degreasers, hot water or steam.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Different parts, different methods
Horizontal duct runs
Grease settles on the floor of a flat duct run. We scrape out the heavy layer first, then the walls and roof are cleaned too.
Access panels
Panels have to seal properly once they’re closed, so grease and air stay inside the duct. We will tell you if any panel needs replacing.
What ductwork cleaning looks like in Broad Colney
There are about 15 cafés, restaurants and staff canteens and about 9 takeaways and sandwich shops across Broad Colney and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, grease doesn’t stop at the filters: it settles along the duct and up the riser. Broad Colney is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s St Albans City council that sends environmental health officers to food businesses in Broad Colney. 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 hall kitchen that only cooks for events, whether near Church of St Peter or elsewhere in Broad Colney, still needs its extract cleaned, just less often. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Napsbury Hospital is the nearest hospital to Broad Colney, about 0.7 miles north-west.
