Ductwork cleaning for kitchens and businesses in Letchworth
Every duct has its own route. A few metres to an outside wall, or a riser up through the building to a roof fan. We map the route during the survey, so we know where to get in and how long it will take. The work covers vertical risers, bends and junctions and attenuators, and the jobs we see most are fat dripping from the ductwork and years of grease along the duct floor.
Around a town like Letchworth, extract cleaning normally means a restaurant, pub, takeaway or the kitchen of a school or care home. Each has a canopy, filters, ductwork and a fan to keep clear of grease, and each is cleaned to the same TR19® standard.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Your questions about ductwork cleaning in Letchworth
Who would carry out a food hygiene inspection at a kitchen in Letchworth?
The local authority for Letchworth is North Hertfordshire council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Do you do school kitchen extract cleaning in Letchworth in the summer holidays?
Yes. The holidays are the usual time for school work. There are about 18 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Letchworth. Send us your term dates when you phone us on 0345 646 2711 or email us, and we will fit the work in.
How do you clean inside the ductwork?
After a survey and grease readings, the duct is opened up through its access panels. Each run and riser is scraped and degreased, then the readings are repeated.
What happens to the waste?
We take it away when we go. During the work, it’s contained to keep the area clean.
Can you fit access panels in our ductwork?
Yes, we do. The survey or clean shows where sections couldn’t be reached, and fitting them means future cleans are more complete.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Are you insured?
Yes. Full insurance covers our work and have been trading since 2009.
What information do you need?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When it’s something else
It’s worth knowing the limits before booking:
- A worn-out fan that needs replacing
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
- Leaking duct joints that need repair
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.

Fixed quotes for ductwork cleaning in Letchworth
The diagnosis comes before the price. We look at:
- Site rules, permits and inductions
- The number of sites or systems
- The scale of the work
- Whether we need access equipment or extra panels
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:

- Photos showing the whole system and its surroundings

Why it’s worth doing now in Letchworth
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. A certificate that covers the ductwork is what they want to see. Each month of use adds to the build-up, so a site in Letchworth is better off booking it now.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes from a few hours to more than one visit, depending on duct length and access, and we clear up before we go. Photos taken on a phone are typically enough for us to plan a job in Letchworth and give a fixed quote.
- First the duct route is traced and every access point noted.
- We measure grease thickness at set points before cleaning.
- We open the panels and scrape out the heaviest grease.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- We test again, take pictures and note any part that couldn’t be reached.
How to prepare
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms

Common problems we fix in Letchworth
Wherever the kitchen is, in Letchworth 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.
Any of these means the system needs a check-up:
- A rancid smell from the extract duct
- Fat dripping from the ductwork
- Thick crusts of old grease along the duct
- Readings above 200 microns from a grease thickness test
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Letchworth is Fairfield Hospital, about 1.9 miles north-west.
Comparing quotes

- What hours they’ll be on site
- Which accreditations they hold, and whether you can check them

Ductwork cleaning in Letchworth: the local picture
The FSA’s food hygiene register shows about 70 restaurants, cafés and works canteens and about 32 takeaways within about 1.5 miles of central Letchworth. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Food hygiene inspections in Letchworth are the job of North Hertfordshire council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Letchworth is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Where a hall near Church of St Paul, or anywhere in Letchworth, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Commuter trade near Letchworth Garden City station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
