Kitchen extracts in Southgate
Food Standards Agency records include about 46 pubs, bars and clubs within 1.5 miles or so of the middle of Southgate. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Southgate get their food hygiene inspections from Enfield council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand. Most London extract cleaning happens at night, after the last service.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Bruce Castle is about 3.2 miles south-east), access may need planning. If you run a church or community hall kitchen, near Christ Church Southgate Parish Church or elsewhere in Southgate, its extract still collects grease from every lunch and event.
Southgate is about 3 miles south-east of Barnet, in Greater London.

Ductwork cleaning in Southgate, done properly
In doctor’s terms, the ductwork is the system’s 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 bends and junctions, access panels and attenuators, and common reasons people get in touch are gaps where access panels were never fitted and readings above 200 microns from a grease thickness test.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Southgate, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
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.
How the visit works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes from a few hours to more than one visit, depending on duct length and access. Security desks and permits-to-work are routine in London, so let us know what your building in Southgate needs from us.
- We start by working out how the duct runs and where it can be opened.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Have your last certificate or report to hand
- Make sure someone can let us in and lock up afterwards

Southgate questions
Can you clean school kitchen extracts in Southgate during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 52 schools and colleges with food registrations within roughly a mile and a half of Southgate. Send us your term dates when you call 0345 646 2711, or email photos, and we’ll fit the work in.
Which fire service covers Southgate?
Fire safety enforcement in Southgate is handled by London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Are you insured?
Yes. We’re fully insured, and we can share the details when you need them.
How is kitchen extract ductwork cleaned?
We get into the duct through its access panels. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What happens if there aren’t enough access panels?
Ductwork needs access to be cleaned. Those parts are listed, and we can install panels so they’re reached next time.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Why act early in Southgate
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. A booked night’s work in Southgate costs you no trading time; an unplanned closure does.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.
Why us?
- CHAS and SafeContractor accredited, with ISO 9001
- We’re fully insured
- One number for every site across the South East and London
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Part by part
Horizontal duct runs
Flat runs of duct link the canopy to the riser or the outside wall. Grease drops out of the slowing air along them, so each section is cleaned through its access panels.
Bends and transitions
A bend can hold far more grease than a straight run of the same length. We clean it back by hand and with degreaser, and readings are taken there before and after.
How we price ductwork cleaning
Before we fix a price, we need to know a few things. We look at:
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- What state the system is in
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or email us for straight advice and a fixed quote.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- A few general shots of the system
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Do you need ductwork cleaning in Southgate?
Air cools as it moves away from the canopy. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
Signs it’s time to call us include:
- Proof of duct cleaning for the insurer
- Thick deposits at the bottom of a vertical duct
- Grease leaking from duct joints
- Thick crusts of old grease along the duct
School kitchens, at schools like Ashmole Primary School for example, are normally cleaned in the holidays so no lunches are lost.
