How we handle ductwork cleaning in Belsize
Each extract duct we take on in Belsize 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 fat dripping from the ductwork and a duct nobody has opened in years, across attenuators, access panels and bends and junctions.
Work in a small place like Belsize starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The paperwork matters as much as the work. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes a shift or more, depending on the length of the runs and the number of access points, and we clear up before we go. A few pictures of the system help us make the most of a visit to a place like Belsize.
- The duct route is surveyed and every access point found.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Before we arrive
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
- Agree a time when the area can be out of use

Belsize: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Belsize?
Food hygiene inspections in Belsize are carried out by Three Rivers council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you do school kitchen extract cleaning in Belsize in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Belsize. Send us your term dates when you call us on 0345 646 2711 or email us, and we will fit the work in.
Do you install duct access panels?
Yes, extra panels can be fitted. That lets the next clean reach sections that were missed, and the report will show where they’re needed.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
How long does ductwork cleaning take?
Duct length, access and grease levels all affect it. Typically it takes a shift or more, depending on the length of the runs and the number of access points.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What if part of the duct cannot be reached?
Sections out of reach are written down on the report, in line with TR19. We can fit new access panels so they’re cleaned next time.
Ductwork cleaning in Belsize: the local picture
Look up Belsize on the FSA’s food hygiene register and you will find about 7 restaurants, cafés and works canteens in Belsize and the streets around it, up to about 1.5 miles out. The duct above a busy canopy coats itself in grease long before anyone sees it. Environmental health officers from Three Rivers council inspect food businesses in Belsize. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Belsize sits within the area of 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.
Bursars and site managers at schools such as Sarratt Church of England Primary School tend to book extract cleaning for when the kitchen is empty. A hall kitchen that only cooks for events, whether near Church of St Paul or elsewhere in Belsize, still needs its extract cleaned, just less often.

When to call us in Belsize
The further the air travels from the cooking, the cooler it gets. As it cools, the grease it carries condenses onto the duct walls, which is why ducts go on gathering grease well beyond the filters.
Look out for these warning signs:
- Grease leaking from duct joints
- A rancid smell from the extract duct
- Duct runs with no cleaning record
- Thick deposits at the bottom of a vertical duct
If your kitchen is in a listed or historic building, like the houses around Belsize (Chenies Manor House is about 2 miles south-west), fitting access panels needs care.

What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Different parts, different methods
Vertical risers
In taller buildings, a riser may pass through several floors and fire compartments, so fire dampers may be fitted where it crosses them. We test those as a separate job.
Horizontal duct runs
A long flat run cannot be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
