Extract fan repair and replacement in Swanley, Kent
Extract fan repair for Swanley and the surrounding area: a survey, a fixed price, careful work and proper paperwork. Call for a fixed quote.
- An extract that vibrates through the ductwork
- An overheating extract motor
- An old fan that needs replacing
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes part of a day for most faults, with a return visit if parts have to be ordered. For a place like Swanley, we load the van from the survey notes so the work can be done in one visit where possible.
- A visit is booked, in the evening or overnight if that suits.
- We isolate the extract and open the fan housing.
- We inspect every moving part and the fixings.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
How to get a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.
Advice
Extract fan repair in Swanley
The extract fan is what pulls smoke, heat and steam out of the kitchen. When it starts to rattle, hum or slow down, the kitchen gets hot and smoky very quickly. We find out why and put it right with a repair or a replacement. If you have a squealing belt on start-up and poor airflow at the canopy, we can put it right.
A callout to a place like Swanley is planned so the first visit fixes as much as possible, based on what you tell us about the fan.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part
Direct-drive fans
Grease on the impeller unbalances a direct-drive fan quickly. Sometimes a clean is all it needs as long as the bearings are still sound.
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease on it throws it out of balance and make it shake.
What we’re called out for in Swanley
When filters clog and ducts fill with grease, the fan has to strain. A motor that strains runs hot, trips out or eventually burns out.
Signs it’s time to call us include:
- An extract fan that has stopped working
- A motor that trips out or overheats
- An extract fan that rattles or knocks
- Poor airflow at the canopy
A fan that rarely runs, like one in a hall kitchen near St Mary the Virgin or elsewhere in Swanley, can seize between uses.

What else we do in Swanley
Extract fan repair in Swanley: local notes
The FSA’s food hygiene register shows about 19 restaurants, cafés and works canteens and about 12 takeaways within roughly a mile and a half of the centre of Swanley. Wherever they cook under a canopy, a failed extract fan stops the kitchen. It’s Sevenoaks council that sends environmental health officers to food businesses in Swanley. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. So a failed fan is worth fixing before the next service, not the next month. Swanley is about 14 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
For school kitchens, at schools like St Bartholomew's Catholic Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time. If you run a café or takeaway near Swanley station, a failed fan in the middle of service is exactly what our 24/7 emergency line is for.

When something else is needed
Not every problem is solved by extract fan repair, and we’ll tell you before any work starts. It does not solve:
- Problems with the electrical supply to the fan (an electrician’s job)
- Faults on the gas side of an interlock system, which need a Gas Safe registered engineer
- Smells from the discharge that need odour control equipment

In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Why act early in Swanley
A noisy fan rarely fixes itself. Worn bearings can seize without much warning, and that often happens mid-service. Sorting it while it still runs is far easier to plan. Systems on quieter sites still build up dirt and wear, just more slowly.
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’re unsure, ring 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
