The kitchen is one of the busiest rooms in the home. A cooker hood helps remove grease, cooking smells, steam and airborne particles while you cook. It also protects kitchen surfaces from moisture and grease build-up.
Getting the installation right is just as important as choosing the right cooker hood. Incorrect positioning or poor installation can reduce extraction performance, create safety risks and even affect your manufacturer's warranty. If you're comparing extractor types, ventilation options or common installation questions, read our cooker hood and extractor fan guide before choosing the right solution for your kitchen.
Why Proper Cooker Hood Installation Matters
A correctly installed cooker hood keeps your kitchen cleaner, improves air quality and helps your extractor perform as intended.
Efficient ventilation
A cooker hood should remove cooking fumes, grease and moisture before they spread around your kitchen. Correct positioning and installation allow it to work efficiently.
Safety
Incorrect installation can create electrical or ventilation issues. If ducting is poorly installed, grease build-up may also increase fire risk.
Warranty protection
Cooker-hood clearance and fixing requirements are model-specific. Follow the exact manufacturer's installation instructions for both the hood and the hob; incorrect clearance or installation can affect safety, extraction performance and warranty coverage.
Protects your kitchen
Steam and grease can damage cupboards, walls and paint over time. Effective extraction helps reduce this.
Helps appliances last longer
Removing excess heat and moisture can reduce wear on nearby kitchen appliances.
Choosing the Right Cooker Hood
The right cooker hood depends on your kitchen size and how you cook.
Extraction rate
Extraction rate measures how much air the hood removes each hour. Larger kitchens or homes where cooking creates more steam or smoke usually benefit from a higher extraction rate.
Kitchen layout
Open-plan kitchens often need stronger extraction to stop cooking smells spreading into living areas.
Keep in mind that higher extraction rates usually produce more noise, so it's worth balancing performance with comfort.
How Far Should a Cooker Hood Be Above the Hob?
There is no single universal clearance that applies to every cooker hood. The correct distance is the clearance stated for the exact hood and hob models being installed.
Manufacturer requirements vary by product. Some manuals specify only a minimum clearance, while others give model-specific positioning or installation limits. Always check the current manual rather than relying on a generic distance.
- Example only: some current Bosch chimney and slimline hoods specify at least 500mm above an induction hob.
- Example only: the same current Bosch guidance specifies at least 650mm above a gas hob. These figures are not universal across brands or models.
Installing a hood higher than the manufacturer intends can reduce capture efficiency because steam, grease and cooking fumes spread before reaching the extractor. Installing it too low can breach the appliance's safety requirements.
Cooker Hood Height: How to Set It Correctly
Use this sequence when setting the height:
- Check the exact cooker-hood installation manual for the stated clearance.
- Check the hob manufacturer's installation manual for any clearance requirement that also applies.
- Where the hood and hob instructions differ, use the requirement that keeps both appliances within their approved installation conditions.
- Keep the hood centred over the cooking zone and within any model-specific positioning limits.
- Plan ducting, electrical connections and fixing points around the manufacturer's specified installation position rather than moving the hood simply to suit the room.
If the required clearance is unclear, use the current manufacturer documentation or ask the manufacturer/installer before fixing the appliance.
Why Use a Professional Cooker Hood Installer?
Professional installers understand manufacturer guidance, ventilation requirements and safe electrical connections.
Choosing a local installer also makes communication easier and can speed up appointments if adjustments are needed.
If you're comparing installers:
- Read customer reviews
- Check qualifications
- Confirm insurance
- Ask for written quotations
- Ask about previous installations
These simple checks help you choose an experienced installer.
