Kitchen extracts in Clerkenwell
Look up Clerkenwell on the FSA’s food hygiene register and you’ll find about 3,487 restaurants, cafés and works canteens and about 922 takeaways and sandwich shops within about 1.5 miles of central Clerkenwell. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Food hygiene inspections in Clerkenwell are the job of Islington council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
For kitchens close to Farringdon station, where the day often starts early and ends late, the extract can be cleaned overnight. Church and community hall kitchens, near St James's Church or anywhere around Clerkenwell, are easy to forget, but their extracts collect grease like any other. If you run catering at a healthcare site, such as a hospital like Finsbury Health Centre about less than half a mile west, the extract may need cleaning more often than a part-time kitchen.
Clerkenwell is about 2 miles north of London, in Greater London. Sites in Clerkenwell get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Clerkenwell is one of 764 places in Greater London we cover for ductwork cleaning.
We work across N1, EC1V and WC1X for ductwork cleaning and the roads nearby. That includes premises on Long Lane, City Road and Noel Road and nearby roads. Clerkenwell is on the A1 and A5201, which makes it straightforward for our technicians to reach for ductwork cleaning. We also cover Farringdon (1 mile south), Angel (1 mile north), Smithfield (1 mile south), Holborn (1 mile south-west) and St Pancras (1 mile west). Further out, we also cover Kensington (5 miles south-west), Walthamstow (5 miles north-east), Hampstead (4 miles north-west), Ruislip (14 miles west), Brompton (3 miles south-west) and Stockwell (4 miles south).
Local landmarks in Clerkenwell
Around Clerkenwell, our work takes us to kitchens and buildings near Barts Health Archives, The Sekforde pub and Elizabeth Garrett Anderson School. Nearby too are Tech City College (within half a mile north-east) and King Square Gardens (under half a mile north-east). There’s a railway station in Clerkenwell itself: Farringdon station. Other landmarks nearby include Brunswick Centre (0.9 miles west) and Montfichet's Tower (0.9 miles south). Green spaces nearby include St. James's Park Lake and Ludgate Hill.
Ductwork cleaning in Clerkenwell, done properly
The ductwork is where an extract clean is won or lost. Sections with no way in can go uncleaned for years. Each section we can reach is cleaned, and any we cannot is written down, so you know exactly where you stand. The work covers horizontal duct runs, access panels and vertical risers, and common reasons people get in touch are grease seeping out of the duct seams and proof of duct cleaning for the insurer.
Kitchens in Clerkenwell, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the quote in Clerkenwell
The quote reflects the site in front of us. We consider:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
When you call or email, it’s useful to have:
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Why act early in Clerkenwell
Dealing with the ductwork in Clerkenwell now beats dealing with it after a problem. It takes a few hours for a short run, longer for long runs and tall risers, and we work evenings, overnight and weekends. Every month a London system goes without attention adds to what has to be done later.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

How the job changes from site to site
Vertical risers
Risers carry the extract up through the building to the roof. Grease runs down the walls and gathers at the base, so the base is one of our test points.
Access panels
Access panels are the doors that let us into the duct. Without them, parts of the duct can’t be reached and the report has to say so.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Clerkenwell questions
Does London parking affect a job in Clerkenwell?
Tell us where a van can stop near your site in Clerkenwell, and about any building rules on loading. If the building has a loading slot system, we will book into it.
Which environmental health team covers Clerkenwell?
Food hygiene inspections in Clerkenwell are carried out by Islington council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

You get a photo report with before and after pictures, and a full TR19 clean also comes with a certificate issued through the BESCA Vent Hygiene Elite portal. File them with the fire risk assessment.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

The duct is cleaned out of hours, evenings, overnight or at weekends. The extract and cooking equipment need to be off.

How long does ductwork cleaning take?
It takes a few hours for a short run, longer for long runs and tall risers. We will confirm the time when we quote.
The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes from a few hours to more than one visit, depending on duct length and access. If your building in Clerkenwell has sign-in rules, permits or key holders, mention them when you book.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Let us know when the site is closed or quiet

Honest limits
Ductwork cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Fire dampers that do not close (they need testing and remedials)
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think.
