What affects the cost of extract fan repair
A fixed price needs a few facts first. We check:
- The times the site is available
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.
Asking for a quote
To speed up the quote, send us:
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

What happens if it’s left?
Weak extraction leaves heat, smoke and fumes in the kitchen. The kitchen becomes an uncomfortable place to work and grease has more chance to settle on surfaces and in the duct. A planned visit to Lewknor is easier to arrange than an emergency callout.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Make sure staff know who to call if the fan fails
- Write down when the fan misbehaves
- Make sure every filter is in place and clean
- Avoid lowering the speed to quieten a fault
We run the fan and check it’s steady before we go. You will hear what we found and what we did along with anything else that needs watching.
A slipping belt or a loose mount is a small job. Left for months, they can damage the motor or bearings so early attention pays.
Extract fans in Lewknor
Food hygiene inspections in Lewknor are the job of South Oxfordshire council’s environmental health team. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. That makes a fan repair urgent rather than something to put off. We cover Lewknor, about 39 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included.
A fan that rarely runs, like one in a hall kitchen near Church of St Margaret or elsewhere in Lewknor, can seize between uses. For school kitchens, at schools like Lewknor Church of England Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a few hours on site, depending on the fault and the access to the fan. Pictures of the system and its access let us plan the work in Lewknor before we set off.
- First, you tell us the symptoms: noise, shaking, weak extraction or no power.
- With the fan safely isolated, we open it up for a proper look.
- We check the motor, bearings, drive, impeller and mountings.
- You hear what’s wrong and what it will cost, with a fixed quote, before we go ahead.
- The repair or replacement is carried out and the fan is run and checked.
How to prepare
- Move anything stored near the system
- Dig out any earlier paperwork for the system
- Let us know about parking and loading

Advice
When something else is needed
Extract fan repair can’t fix everything, and we will tell you before we start. It doesn’t solve:
- Odour complaints that need filtration rather than a fan repair
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Wiring and supply faults beyond the fan itself
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think before you book.

FAQs for Lewknor
Is Lewknor within the area you cover?
Yes, we work in villages as well as towns, and Lewknor is covered. Photos of the system and directions to the site help us plan the visit.
Which environmental health team covers Lewknor?
In Lewknor, it’s South Oxfordshire council that carries out food hygiene inspections. Inspections are risk-based, so a visit can come at any time, including the week a fan stops.
Is it worth cleaning the extract while you’re fixing the fan?
Repairing the fan doesn’t clean the canopy or ducts. Grease on the fan typically means grease in the ducts, and we can arrange both.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
How long will the fan be out of action?
Most fan jobs take part of a day for most faults, with a return visit if parts have to be ordered, including testing. We plan the work around your service wherever we can.
Different parts, different methods
Belt-driven fans
With belts and pulleys, there’s more to wear. More parts to inspect, but many faults are straightforward to fix.
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. The cause might be grease restricting the airflow, or the motor itself may be failing.
