About our ductwork cleaning in Highgate
Nobody sees duct grease building, so nobody notices it until something goes wrong. A flare-up drawn up from the range can light it, and fire can then run along the ductwork to other parts of the building. Cleaning the duct takes that fuel away. Common call-outs are for years of grease along the duct floor and readings above 200 microns from a grease thickness test, on attenuators, multi-storey ducts and bends and junctions.
Kitchens in Highgate, 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, which is why keeping it clean to TR19® matters.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why act early in Highgate
Dealing with the ductwork in Highgate now beats dealing with it after a problem. The work 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.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Grease, kitchens and Highgate
Food Standards Agency records list about 319 restaurants, cafés and canteens and about 82 takeaways in and around Highgate, up to about a mile and a half out. Behind every canopy among them is a run of ductwork that collects grease out of sight. It’s Haringey council that sends environmental health officers to food businesses in Highgate. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. London Fire Brigade covers Highgate. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Highgate is Highgate Private Hospital, about 0.6 miles north-west. For kitchens close to Upper Holloway station, where the day often starts early and ends late, the extract can be cleaned overnight.
Highgate is about 2 miles north-east of Hampstead, in Greater London. Highgate gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. We cover 764 places across Greater London, large and small.

Around Highgate
Locally, jobs take us to businesses close to The Angel Inn, St Aloysius RC College and Whittington Park, among other places. Highgate’s nearest station is Upper Holloway station, about 0.9 miles south-east of the centre. Nearby you will also find Highgate Private Hospital (0.6 miles north-west) and Montfichet's Tower (4.4 miles south-east). For a walk, there’s Darland's Lake and Parkland Walk.
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Store the certificate with the fire risk assessment
- Tell us if grease leaks from the ductwork
- Leave a way through to the access panels
- Run the extract fan throughout service
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Grease and dirty water are contained and removed.
Extra access panels mean more of the duct gets cleaned each time. It doesn’t stop grease forming, but it stops it building unseen.
What ductwork cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A failed fan motor at the end of the duct (a fan repair job)
- Duct sealed behind fixed ceilings or walls
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
If in doubt, call 0345 646 2711 or use the quote form and we will say what we think before booking.

For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Common questions in Highgate
Can the work in Highgate be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Highgate needn’t be disturbed. Your opening times are the first thing we ask for.
Who inspects food businesses in Highgate?
In Highgate, it’s Haringey council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Can you quote from photos?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What we are called out for in Highgate
Slow air leaves the most grease behind. Flat runs, bends, reducers and the base of risers are the usual hotspots, and those are the points we pay most attention to.
Most sites get in touch after spotting something like this:
- A rancid smell from the extract duct
- Grease leaking from duct joints
- Ductwork that has never been cleaned
- Sections of duct with no access panels
If you look after a school kitchen, at a school such as St Michael's Church of England Primary School or anywhere near Highgate, the holidays are the usual time for a TR19® clean.
What your quote should include
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
- What paperwork you get at the end
- Whether the quote is based on a survey or photos
What affects the cost of ductwork cleaning
Your quote is based on your site. We consider:
- How many systems or sites are involved
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- Any permits to work or inductions
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
What we need to know
We can often survey from photos. The most useful are:
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
Getting a quote doesn’t take long. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes anything from a few hours to several visits, depending on the length of duct. We fit London jobs around the building rather than the other way round, so a visit in Highgate is typically out of hours.
- Diagnosis: a survey of the duct’s route, size and access.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- Bends, risers and the base of each riser get extra attention.
- Readings, photos and a recommended next clean date complete the job.
How to prepare
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
