FAQs for Langley
Which fire and rescue service is responsible for Langley?
Fire safety enforcement in Langley is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who would carry out a food hygiene inspection at a kitchen in Langley?
Kitchens in Langley are inspected by North Hertfordshire council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
Who has the legal duty for fire safety?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Do you provide a report after cleaning the fan?
A photo report, including the fan’s condition and the next clean date. Keep it with your maintenance log.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Extract fan cleaning for kitchens and businesses in Langley
Think of the fan as the system’s heart and the grease as a clot. A greasy fan works harder and moves less air. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. Typical jobs include a motor area thick with grease and a noisy fan that has got louder over time, across roof-mounted fans, fan housings and axial fans.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the visit works
At the end of the visit, someone from your team can look over the work with us.

- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.

Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Why act early in Langley
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. Rural sites cannot always move to another kitchen or room when something fails.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before work begins.
Why choose Duct Doctor in Langley
- In business since 2009
- Evenings, overnight and weekends, plus 24/7 emergency callout

What else we do in Langley
Langley kitchens: local notes
Food Standards Agency data counts about 28 restaurants, cafés and canteens and about 8 sandwich bars and takeaways across Langley and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Langley is covered by 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. It’s North Hertfordshire council that sends environmental health officers to food businesses in Langley. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
School kitchens, at schools like The Thomas Alleyne School for example, are usually cleaned in the holidays so no lunches are lost. If your kitchen is in a listed or historic building, like the houses around Langley (Knebworth House is about 1.3 miles south-east), fitting access panels needs care.
Langley is about 3 miles south-west of Stevenage, in Hertfordshire. Every kind of commercial site in Langley, extract fan cleaning is something we can help with. We can work out of hours so the site keeps running. Our Hertfordshire coverage runs to 381 places, Langley among them. Our Milton Keynes page covers sites nearby, about 25 miles away.

Open spaces near Langley include Ridlins Mire.
What extract fan cleaning cannot fix
To be straight with you, there are a few things this work will not fix:
- A fan that will not start
- A fan that was never right for the kitchen
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
Not sure which it is? You can call 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.
Where we work
- In-line fans
- Fan housings

How we price extract fan cleaning
The diagnosis comes before the price. We look at:
- How big the system is
- How many systems or sites are involved
- Any permits to work or inductions
- A single visit or a regular plan
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Problems your staff have spotted
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- Wide photos of the system and the area around it
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
Aftercare tips
After the visit, a few habits help the work last:
- Report grease escaping from the fan
- Make sure the fan is included each time
- Don’t turn the fan off mid-service
- Tell us if the extract feels weaker
File the photo report with your other extract records. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.
When to call us in Langley
Poor filters mean a greasier fan. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
Any of these means the system needs a check-up:
- A fan motor running hot under a coat of grease
- Grease escaping from the fan outlet
- A fan that has never been cleaned
- A fan that hums, whines or rumbles
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Langley is Lister Hospital, about 2.7 miles north.
What your quote should include
- Exactly which parts of the system are covered
- Whether they’re fully insured
- Whether the figure could change on the day
- How areas they cannot reach will be recorded
