Ductwork cleaning for kitchens and businesses in High Wych
Once air leaves the canopy, it travels through ductwork that most people never see. Every horizontal run and vertical riser collects grease along the way, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. Common call-outs are for thick crusts of old grease along the duct and grease leaking from duct joints, on horizontal duct runs, bends and junctions and multi-storey ducts.
In a small place like High Wych, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

High Wych kitchens: local notes
Food Standards Agency records include about 14 pubs, bars and clubs and about 3 hotels and B&Bs in and around High Wych, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. In High Wych, food businesses are inspected by environmental health officers from East Hertfordshire council. 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 High Wych is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you run catering at a healthcare site, such as a hospital like Princess Alexandra Hospital about 3 miles south-west, the extract may need cleaning more often than a part-time kitchen. School kitchens, at schools like High Wych Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost. Historic houses near High Wych, such as Much Hadham Palace about 3.9 miles north-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

What affects the cost of ductwork cleaning
The quote reflects the site in front of us. We take into account:
- How big the system is
- The condition we find in the survey
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
When you call or email, these details help:
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- A few general shots of the system
- Problems your staff have spotted
For a fixed quote, give us a ring on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Keeping the system healthy
After the visit, a few habits help the work last:
- Have the grease measured if cooking hours go up
- Make sure filters are seated properly
- Consider fitting panels where the report shows gaps
- Keep to the interval on the report
Every panel we open is refitted when we finish, and the area around them is cleaned down. Waste grease and water are taken away.
Keep the fan on throughout service. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
Questions from High Wych
Which environmental health team covers High Wych?
Food hygiene inspections in High Wych are carried out by East Hertfordshire council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which fire and rescue service is responsible for High Wych?
Fire safety enforcement in High Wych is handled by Hertfordshire Fire and Rescue Service. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How much does ductwork cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, typically ready within one working day.
Do I get a certificate for ductwork cleaning?
When the duct is cleaned as part of a full TR19 clean, you get a TR19 certificate and a photo report. It includes readings, pictures and any unreachable sections.
When something else is needed
We’d rather tell you now than book work that won’t help, so here are the limits:
- Ductwork that is corroded, split or holed (that needs a ductwork contractor)
- A failed fan motor at the end of the duct (a fan repair job)
- Duct sealed behind fixed ceilings or walls
If you are not sure, just ring 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.
Where we work
- Multi-storey ducts
- Attenuators
- Horizontal duct runs
- Bends and junctions
- Vertical risers
- Access panels
What happens on the day
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes from a few hours to more than one visit, depending on duct length and access. A quick note on how to find the site and where to park makes a visit to High Wych run smoothly.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, photos and a recommended next clean date complete the job.
Preparing for the visit
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system

Advice
Why deal with it now?
TR19® isn’t law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Out of sight is the usual reason a rural system goes too long without attention.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.

Places near High Wych
Also in High Wych
Different parts, different methods
Multi-storey and shared buildings
In a building with several floors, the duct may pass other tenants’ spaces. Access is planned with the building’s managers, so the clean is done safely and quietly.
Attenuators and discharge
Near the discharge, the air has cooled the most, which can mean heavier deposits. We include it in the clean and the readings.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
