Extract fan cleaning for kitchens and businesses in Nalderswood
Grease on a fan isn’t spread evenly. Uneven build-up unbalances the impeller, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. The work covers centrifugal fans, roof-mounted fans and in-line fans, and the jobs we see most are a fan that hums, whines or rumbles and less air being pulled from the kitchen.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
What affects the cost of extract fan cleaning
You will get a fixed price before we start. It takes into account:
- The size of the system
- Site rules, permits and inductions
- What state the system is in
- How easy every part is to reach
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then give us a ring on 0345 646 2711, or email photos.
When it’s something else
In fairness, there are a few things this work won’t fix:
- A faulty speed controller or isolator
- A failed motor or worn bearings (that needs a fan repair or replacement)
- A cracked or broken impeller (it needs replacing)
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think before booking.
What the work covers

What the work involves, part by part
Wall fans
With little duct before them, wall fans collect grease fast. They may need cleaning as often as the canopy, which grease readings will show.
Roof-mounted fans
Roof fans sit at the top of the riser. We clean them where they can be safely reached, with any limits noted.
Nalderswood kitchens: local notes
It’s Mole Valley council that sends environmental health officers to food businesses in Nalderswood. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Nalderswood is about 22 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.
Healthcare kitchens, like those at hospitals such as East Surrey Hospital (about 3.7 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands. Volunteers running a hall kitchen near Church of St Bartholomew, or anywhere in Nalderswood, may not know when the extract was last cleaned, and a grease test settles it.
Nalderswood is about 3 miles west of Horley, in Surrey. Anywhere in RH2, we can carry out extract fan cleaning at your premises. Our Surrey coverage runs to 395 places, and Nalderswood is one of them. We also work in Guildford, about 15 miles from Nalderswood.

Neighbouring places we cover for extract fan cleaning include Norwood Hill (1 mile south-east), Shellwood Cross (1 mile west), Parkgate (2 miles south-west), Cudworth (2 miles south-west) and Charlwood (3 miles south).

Around Nalderswood
Around Nalderswood, our work takes us to kitchens and buildings near Edolph's Copse and the streets around them. The nearest railway station is Salfords station, roughly 3.4 miles east. Nearby you’ll also find Reigate Priory Museum (3.3 miles north-east) and East Surrey Hospital (3.7 miles north-east). Not far away are Reigate Heath and Colley Hill.
Do you need extract fan cleaning in Nalderswood?
A fan in Nalderswood 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. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Most sites get in touch when they notice something like this:
- A motor area thick with grease
- Burning smells from the fan area
- A fan that no longer moves enough air
- An extract fan that vibrates or rattles
Bursars and site managers at schools such as Burys Court School tend to book extract cleaning for when the kitchen is empty.

Questions from Nalderswood
Who is the fire and rescue service for Nalderswood?
Nalderswood is in the area of Surrey Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can you come to Nalderswood after we close?
Yes, evening, overnight and weekend work is normal for us. It means the site in Nalderswood keeps running as normal. When you call us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Who has the legal duty for fire safety?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Is the fan included in a TR19 clean?
Yes, it should be. The whole system is cleaned, from the canopy to the discharge, and the fan is a key part of it, so it’s cleaned too.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
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.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

What else we do in Nalderswood
Why deal with it now?
A fan that sounds rough in Nalderswood is often telling you the extract needs a clean. If the fan is coated, the duct before it usually is too, so it’s worth checking the whole system. Equipment tucked in a roof space or outbuilding near Nalderswood rarely gets looked at unless someone books it.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
