Extract fan cleaning for kitchens and businesses in Furnace Green
Every TR19® Grease clean includes the extract fan, but a fan can also need attention on its own, especially when it has started to vibrate or sound rough. Where only the fan is cleaned, the report says so. If you have hot, greasy smells near the fan and grease stains around the discharge, we can put it right, from axial fans, fan housings and roof-mounted fans onwards.
In a smaller place like Furnace Green, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Why act early in Furnace Green
Grease on the impeller makes the fan less efficient. Less air is pulled from the kitchen, so heat and smoke linger and the motor works harder. When a site near Furnace Green shuts unexpectedly, the people who rely on it notice at once.
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 give you a fixed price before we start.

Signs you need extract fan cleaning in Furnace Green
By the time air reaches the fan, it has passed the canopy, filters and duct. The grease that is left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
It’s time to book a visit if you see:
- Weak extraction at the canopy
- Fat spreading onto the roof or wall by the fan
- Hot, greasy smells near the fan
- A heavily greased fan housing
School kitchens, at schools like Brook Infant School for example, are usually cleaned in the holidays so no lunches are lost.
What your quote should include
- Whether the price is fixed
- What insurance they carry
- If they look at the system before pricing
- When they can work, and whether that’s outside your opening hours
What affects the cost of extract fan cleaning
The diagnosis comes before the price. The main factors are:
- The condition of the system
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- How big the system is
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
Asking for a quote
To help us quote quickly, send us:
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- A few general shots of the system
- When the site is open and when it’s quiet
To get a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Environmental health officers from Crawley council inspect food businesses in Furnace Green.

What we do, step by step

All told, the work takes a few hours where there are several fans or heavy deposits. In a smaller place like Furnace Green, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we check the fan’s condition and how it sounds.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.

- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
Getting a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

Furnace Green questions
Who inspects food businesses in Furnace Green?
That’s Crawley council, whose environmental health officers carry out food hygiene inspections in Furnace Green. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you work overnight in Furnace Green?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Furnace Green needn’t be disturbed. Your opening times are the first thing we ask for.
What if the fan needs more than a clean?
A clean won’t mend wear. Where the fan needs repair or replacement, we can do that too, with a fixed quote first.
How often does the fan need cleaning?
It depends on how many hours the kitchen cooks, under BESA guidance. At the extremes, that’s 3-monthly for heavy use and 12-monthly for light use, fan included.
Why is my extract fan noisy?
An unbalanced impeller, usually from uneven grease, is a common cause. After cleaning, we will tell you if wear or damage is also involved.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Can you clean the fan on its own?
Yes, we do. The report will make clear that only the fan was cleaned, so your TR19 records stay accurate. The full system still needs its regular TR19 clean.
Is it safe to clean the fan while the kitchen is open?
It has to be off and isolated, for safety. Cleans are done when the kitchen is closed, so cooking is not affected.
How the job changes from site to site
Inline duct fans
Inline fans sit within the duct run, often above a ceiling. We get to them through the duct or casing after isolating them.
Fan housings and motors
Some fans use a belt drive. Belts and pulleys are checked and cleaned where safe for your records.
