Extract fan repair in Northbrook, done properly
Everything a kitchen extract does depends on the fan. Once it turns noisy, sluggish or stops altogether, the cooking area soon fills with heat and fumes. Our engineers track down the fault and fix it, by repairing the fan or replacing it. If you have an extract that vibrates through the ductwork and an extract fan that has stopped working, we can put it right.
Somewhere as small as Northbrook, a kitchen extract fan might serve a pub, a school, a care home or a hall kitchen. A failed fan stops the kitchen, and our 24/7 emergency line covers rural addresses too.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two to diagnose, then longer if parts or a new fan are needed. Somewhere as small as Northbrook, the date and timings are agreed with you well before the day.
- You describe the fault and we arrange a visit.
- We isolate the fan before touching it.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Before we arrive
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
Ask for a quote
The quickest way to a quote is to send pictures: 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 we can price many jobs without a visit.

When it’s something else
Not every problem is solved by extract fan repair, and we will tell you before work begins. It doesn’t solve:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Wiring and supply faults beyond the fan itself
- A system that needs redesigning rather than repairing
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.
Where we work

What we are called out for in Northbrook
Not every problem is mechanical. Speed controllers, isolators and wiring can all fail so we check the controls before blaming the motor.
These are the problems we see most often:
- A knocking noise from the extract fan
- A worn or slipping fan belt
- A humming noise from the fan motor
- A dead fan motor
For school kitchens, at schools like Micheldever CofE Primary School for example, a planned fan repair in the holidays avoids losing lunches in term time.

When a fan fails in Northbrook
It’s Winchester City council that sends environmental health officers to food businesses in Northbrook. Food premises are expected to have suitable and sufficient ventilation under food hygiene rules. So a failed fan is worth fixing before the next service, not the next month. Northbrook, about 56 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
A fan that rarely runs, like one in a hall kitchen near Church of St Mary or elsewhere in Northbrook, can seize between uses.
Northbrook is about 7 miles north of Winchester, in Hampshire. From the centre of Northbrook to the outskirts, extract fan repair is available to all kinds of commercial premises, from a single unit to a large public building.

Fixed quotes for extract fan repair in Northbrook
A fixed price needs a few facts first. We check:
- How easy every part is to reach
- One-off work versus a regular cycle
- The condition of the system
- Working hours and out-of-hours timing
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.
Asking for a quote
You do not need the technical terms. Just send:
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Why deal with it now?
In Northbrook, as elsewhere, an extract fan may well sit outside on a wall or roof, where a rattle or a whine can be heard beyond the kitchen. Fixing the cause quietens it down before neighbours notice. Somewhere as small as Northbrook, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Don’t cook with gaps in the filter bank
- Report new noises from the fan early
- Keep a record of any trips or stoppages
- Keep the area around the fan controls clear
Clean filters help a repaired fan stay that way. The less grease that reaches the fan, the longer its parts last and fewer faults.
Clogged filters make the fan strain. Keeping filters clean eases the strain and helps prevent overheating.

Direct-drive fans
Many kitchen extracts use direct-drive fans. When the motor fails, replacing the whole fan unit can make more sense than repairing it and we will talk you through it.
Belt-driven fans
With belts and pulleys, there’s more to wear. That means more to check, but often a simpler repair.
Your questions about extract fan repair in Northbrook
Do you work overnight in Northbrook?
Yes, we can come after you close and finish before you open. That way a site in Northbrook does not have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Can you come out to a failed extract fan in Northbrook out of hours?
Day or night, a failed fan in Northbrook can be reported on our emergency line. Call 0345 646 2711 and tell us what the fan is doing, or not doing. If you can, stop cooking until the fan is checked.
Will we have to shut during the visit?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What paperwork should we keep on file?
Anything that proves the system is maintained: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.
What will a fan repair or replacement cost?
We can’t price it without knowing the fault. After we have checked the fan, we give you a fixed price for the repair or the replacement.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What about areas you cannot get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
