Extract fan cleaning around Dorking
Food Standards Agency data counts about 59 restaurants, cafés and works canteens and about 10 takeaways and sandwich shops within roughly a mile and a half of the centre of Dorking. Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. Kitchens in Dorking get their food hygiene inspections from Mole Valley council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Dorking is covered by Surrey 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.
A kitchen near Dorking Deepdene station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Church and community hall kitchens, near Church of St Paul or anywhere around Dorking, are easy to forget, but their extracts collect grease like any other. If you look after a school kitchen, at a school such as St Paul's CofE (Aided) Primary School or anywhere near Dorking, the holidays are the usual time for a TR19® clean.

About our extract fan cleaning in Dorking
In Dorking, as everywhere we work, the fan follows a set routine: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. Typical jobs include a fan that no longer moves enough air and hot, greasy smells near the fan, across roof-mounted fans, fan housings and axial fans.
Kitchens in towns like Dorking are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Sections we can’t reach are listed on the report, and access panels can be added.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the job changes from site to site
Inline duct fans
Some fans are built into the duct itself. We get to them through the duct or casing after isolating them.
Fan housings and motors
Some fans use a belt drive. We clean around them and note any wear for your records.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes an hour or two for most single fans, and the area is cleaned down before we leave. A few pictures of the system and its access points help us plan a visit in Dorking.
- 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.
- The fan is degreased, taking care around the motor.
- We reassemble, run and photograph the fan.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Advice
When something else is needed
In fairness, some problems need a different fix:
- An impeller that is bent or split
- A faulty speed controller or isolator
- A failed motor or worn bearings (that needs a fan repair or replacement)
If in doubt, ring 0345 646 2711 or drop us a line and we’ll say what we think.

What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Facilities teams in offices, schools and healthcare sites book us too in Dorking and across Surrey. Larger estates can be phased building by building around the people who use them.
FAQs for Dorking
Who inspects food businesses in Dorking?
Food hygiene inspections in Dorking are carried out by Mole Valley council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Who is the fire and rescue service for Dorking?
It’s Surrey Fire and Rescue Service, which covers Dorking. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Do you work in Dorking?
Yes. Our area takes in London and the counties of South East England, and that includes Dorking.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Is the fan included in a TR19 clean?
Yes, it should be. A TR19 Grease clean covers everything from canopy to discharge, and the fan is a key part of it, so it’s cleaned too.
Can you fix a fan that’s worn out?
Cleaning removes grease, but it cannot fix worn parts. We repair and replace extract fans as well, with a fixed quote first.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do we need to close while you work?
Not typically. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
Aftercare tips
Once we’ve finished, these simple steps help:
- Leave a clear route to the fan
- Report rattles or humming early
- Do not turn the fan off mid-service
- Check the report shows the fan was cleaned
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Why deal with it now?
An unbalanced fan gets worse, not better. It wears bearings and mounts and can lead to a breakdown and a kitchen can’t cook safely without extraction. A planned clean beats an emergency. An inspector or insurer will want to see recent records, so it makes sense to have them ready.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
