Questions from Kings Langley
Which fire authority looks after Kings Langley?
Fire safety enforcement in Kings Langley is handled by Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you clean school kitchen extracts in Kings Langley during the holidays?
Yes, holiday work suits schools best. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Kings Langley. You can call 0345 646 2711 or drop us a line with the dates the site is empty.
How long will it take to clean the fan?
A single accessible fan does not take long, while fans on high roofs or in tight voids take longer. We plan it out of hours.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can you set up regular visits?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Extract fan cleaning in Kings Langley
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. Common call-outs are for a heavily greased fan housing and a fan shaking on its mounts, across discharge points, in-line fans and fan housings.
Kitchens around a place like Kings Langley are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Flat runs collect grease and need proper access to clean.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Keeping the system healthy
To keep the system working properly between visits:
- Do not turn the fan off mid-service
- Keep records of every fan clean
- Watch for grease marks around the outlet
- Flag smoke lingering at the canopy
The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.

What happens if it’s left?
A fan that fails mid-service can stop a kitchen cooking. Many fan problems start with grease, so cleaning the fan helps keep it working. We also offer a 24/7 emergency callout if the worst happens. A visit arranged in advance is far less disruptive than a callout on a busy day.
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.

Extract fan cleaning around Kings Langley
According to Food Standards Agency records, there are about 12 pubs, bars and clubs across Kings Langley and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Fire safety in Kings Langley falls to 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. In Kings Langley, food businesses are inspected by environmental health officers from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Church and community hall kitchens, near Church of All Saints or anywhere around Kings Langley, are easy to forget, but their extracts collect grease like any other. If you cook for passing trade around Kings Langley station, the extract can be cleaned between your last and first customer.

What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:

- Close-ups of filters, grilles, hatches or access panels

What extract fan cleaning can’t fix
Extract fan cleaning cannot fix everything, and we’d rather say so up front. It won’t put right:

- Wiring faults to the fan
If you are not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.

How the job changes from site to site
Impellers and blades
A clean impeller shows any damage: chips, distortion or wear. Anything we see goes on the report.
Wall fans
Grease can mark the outside wall around the fan. We clean the fan and check the outlet.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for one fan, longer when it’s hard to reach. Everything the job in Kings Langley needs is worked out beforehand, from the survey.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- We remove the grease from the blades, impeller and casing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
