Different parts, different methods
Impellers and blades
The blades of the impeller do the work, and grease builds up on them unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.
Fan housings and motors
Motors and their electrics are kept dry and treated with care, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.
How we handle extract fan cleaning in Great Missenden
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. If you are dealing with a noisy fan that has got louder over time and burning smells from the fan area, we can put it right.
In a small place like Great Missenden, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Questions from Great Missenden
Who carries out food hygiene inspections in Great Missenden?
Food hygiene inspections in Great Missenden are carried out by Buckinghamshire council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you cover smaller places like Great Missenden?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
How much does extract fan cleaning cost in Great Missenden?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Does the law say we must follow TR19?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
How long is a fan clean?
Size, access and build-up all affect it. As a guide, it takes an hour or two for most single fans.
How we price extract fan cleaning
You will get a fixed price before we start. It takes into account:
- The scale of the work
- Where the site is and how we reach it
- One-off work versus a regular cycle
- The condition we find in the survey
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.
What to send for a quote
What to send for a quote:
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
If you need extract fan cleaning in Great Missenden, call 0345 646 2711 or drop us a line. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Landlords, agents and facilities managers
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a couple of hours per fan, depending on its size and the build-up. Seeing the system in photos first means the trip to Great Missenden can be planned properly.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Before we arrive
- Move anything stored near the system
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- File the fan’s report with your other records
- Watch for grease marks around the outlet
- Check filters are seated before cooking
- Don’t store items in front of the fan’s access point
If the fan needs more than a clean, we will say so plainly. We also repair and replace extract fans, so you have one point of contact.
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.

What else we do in Great Missenden
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
