Hanscombe End extract fan cleaning
Extract fan cleaning in Hanscombe End, surveyed first and signed off with a written report and pictures. Ask us for a fixed quote.
- Weak extraction at the canopy
- A fan that hums, whines or rumbles
- Hot, greasy smells near the fan
Aftercare tips
After the visit, a few habits help the work last:
- Run the extract throughout cooking
- File the fan’s report with your other records
- Watch for grease marks around the outlet
- Notice when the fan starts to sound different
We take away the grease and dirty water from the fan clean. Wherever the fan is, the area around it is cleaned down.
Run the fan throughout cooking. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Extract fan cleaning for kitchens and businesses in Hanscombe End
Duct Doctor has been cleaning kitchen extract fans since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. Typical jobs include a noisy fan that has got louder over time and burning smells from the fan area, on in-line fans, discharge points and fan housings.
Somewhere as small as Hanscombe End, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
What affects the cost of extract fan cleaning
You’ll get a fixed price before any work starts. It takes into account:
- Travel, parking and unloading
- How easy every part is to reach
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
What to send for a quote
When you call or email, it’s useful to have:
- Detail shots of panels, filters and grilles
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
To get a fixed quote, phone us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
Grease, kitchens and Hanscombe End
Hanscombe End, about 36 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. Hanscombe End 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.
If you look after a school kitchen, at a school such as Shillington Lower School or anywhere near Hanscombe End, the holidays are the usual time for a TR19® clean. A hospital like Keech Hospice Care, about 5.2 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Hanscombe End is about 5 miles north-west of Hitchin, in Hertfordshire. From the centre of Hanscombe End to the outskirts, we cover extract fan cleaning for every kind of premises, from a single unit to a large public building. Hanscombe End is one of 381 towns, villages and districts in Hertfordshire where we work for extract fan cleaning. There’s also a page for Milton Keynes, about 17 miles away.

Landmarks near Hanscombe End

When to call us in Hanscombe End
A fan on a roof or hidden in a ceiling void is easy to forget. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
Keep an eye out for these warning signs:
- Burning smells from the fan area
- A fan that has never been cleaned
- Grease escaping from the fan outlet
- A fan that hums, whines or rumbles
A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in Hanscombe End, still needs its extract cleaned, just less often.

Common questions in Hanscombe End
Is Hanscombe End within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Who enforces fire safety at workplaces in Hanscombe End?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Hanscombe End. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
How long will it take to clean the fan?
Allow a few hours where there are several fans or heavy deposits. We will confirm the time when we quote.
Can the fan be cleaned between full cleans?
Yes, we do. We record it as a fan-only clean, so your TR19 records stay accurate. The full system still needs its regular TR19 clean.
Can the work be done while we are closed?
Yes. Tell us your opening hours when you ask for a quote and we’ll plan the visit around them.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a couple of hours per fan, depending on its size and the build-up. Pictures of the system and its access let us plan the work in Hanscombe End before we set off.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it cannot start while we work.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- The fan is put back into service, checked and photographed.
Preparing for the visit
- Agree a time when the area can be out of use
- Move anything stored near the system
- Mention any parking or loading restrictions
Get a fixed quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
