Ductwork cleaning in Harefield, 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 can’t is written down, so you know exactly where you stand. Common call-outs are for an insurer asking for TR19 evidence and sections of duct with no access panels, across vertical risers, attenuators and multi-storey ducts.
In a smaller place like Harefield, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours for a short run, longer for long runs and tall risers. In a smaller place like Harefield, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we diagnose: the route, the access and the grease levels.
- You get a fixed price before work starts.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, photos and a next clean date.
Preparing for the visit
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
What else we do in Harefield
Why it’s worth doing now in Harefield
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. It’s better to plan the work at a site near Harefield than wait for a failure.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.

What the work involves, part by part
Vertical risers
A riser takes the duct up through one or more floors. Grease collects on the walls and at the foot of the riser, so the base is one of our test points.
Attenuators and discharge
At the end of the duct is the discharge. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
FAQs for Harefield
Do you work overnight in Harefield?
Yes, evening, overnight and weekend work is normal for us. The work in Harefield can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
Can you clean school kitchen extracts in Harefield during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Harefield. Send us your term dates when you call us on 0345 646 2711 or email us, and we will fit the work in.
What about areas you cannot get to?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Is Harefield in your area?
Yes. Our area takes in London and the counties of South East England, Harefield included.
Is a quote from photos possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures aren’t enough, we’ll survey first.
How is kitchen extract ductwork cleaned?
We open each access panel and clean the section it reaches. Heavy grease comes out by hand, and what’s left is degreased, with readings taken before and after.
Who is responsible for fire safety on the premises?
That depends on who controls the premises. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
Aftercare tips
After the visit, a few habits help the work last:
- Leave a way through to the access panels
- Store the certificate with the fire risk assessment
- Make sure filters are seated properly
- Report any grease dripping from duct joints
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the pictures make the duct’s condition easy to see.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.
Grease, kitchens and Harefield
Food Standards Agency records list about 12 cafés, restaurants and staff canteens and about 5 takeaways and sandwich shops within roughly a mile and a half of the centre of Harefield. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. In Harefield, food businesses are inspected by environmental health officers from Hillingdon council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Harefield is covered by Buckinghamshire 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.
If you run catering at a healthcare site, such as a hospital like Harefield Hospital about less than half a mile north-west, the extract may need cleaning more often than a part-time kitchen. Ickenham Hall, about 3.4 miles south-east, is one of the historic houses near Harefield; if you run event catering at a venue like that, cleans can be booked between functions. For schools such as Harefield Infant School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
