Shephall: your questions answered
Will you come out to Shephall?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Which fire service covers Shephall?
It’s Hertfordshire Fire and Rescue Service, which covers Shephall. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Is TR19 a legal requirement?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Should the extract fan be cleaned as part of TR19?
Yes, the fan is part of a full TR19® Grease clean. It’s isolated, opened and cleaned along with the canopy, plenum, filters, ducts and discharge.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Who has the legal duty for fire safety?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Do you need to turn the fan off to clean it?
We isolate the fan, so the kitchen cannot cook while we work. That is why fan cleans are done out of hours, and the kitchen is ready when we leave.

When to call us in Shephall
A fan in Shephall builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
If you notice any of these, it’s worth a diagnosis:
- Vibration from an unbalanced impeller
- A fan that has never been cleaned
- Grease stains around the discharge
- Weak extraction at the canopy
Church and community hall kitchens, near Church of Saint Mary or anywhere around Shephall, are easy to forget, but their extracts collect grease like any other.
What to look for in a quote
- If they look at the system before pricing
- Whether the figure could change on the day
- Whether a written report and photos are included
- Whether they’re fully insured

What happens if it’s left?
Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. Booking ahead lets us plan the trip to Shephall at a time that suits you.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

What the work involves, part by part
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.
What extract fan cleaning looks like in Shephall
The Food Standards Agency lists about 21 bars, pubs and nightclubs and about 4 hotels, B&Bs and guest houses as registered food businesses in Shephall and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Shephall, food businesses are inspected by environmental health officers from Stevenage council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Hertfordshire Fire and Rescue Service covers Shephall. 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 your kitchen is in a listed or historic building, like the houses around Shephall (Aston Bury is about 1.6 miles south-east), fitting access panels needs care. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Shephall is Lister Hospital, about 2.7 miles north-west.

How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes an hour or two for most single fans. A site near Shephall typically has room to park, so the questions are about access to the system and your hours.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
Getting a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

Before booking, it helps to know what’s not included:

If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think.

What affects the cost of extract fan cleaning
The survey tells us what the work involves. The main factors are:
- Site rules, permits and inductions
- Parking and loading at the site
- Whether we need access equipment or extra panels
- A single visit or a regular plan
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Problems your staff have spotted
- Any previous report or certificate
- A few general shots of the system
- Detail shots of panels, filters and grilles
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Then call us on 0345 646 2711 or drop us a line.
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
