Choosing a Kitchen Extractor Hood: A Practical UK Homeowner’s Guide
A cooker hood is easy to choose by appearance. You find one that matches the hob, check the width and move on. Yet the details you cannot see, especially the air route and installation, often decide whether it is pleasant to use every evening.
Whether you are replacing a noisy old hood or planning a new kitchen, start with how you cook and where the air can go. A good choice should suit the room, be straightforward to clean and fit your budget after installation.
Decide between extraction and recirculation first
A ducted hood draws cooking air through grease filters and sends it outdoors through ducting. A recirculating hood passes air through grease and odour filters before returning it to the kitchen. Some models support either arrangement, but may need additional parts.
That distinction matters if steam is your main frustration. A conventional recirculating hood does not discharge moisture outside, so it should not be treated as a substitute for the room’s ventilation. Ask your installer how the kitchen’s overall ventilation will work.
Ducted extraction can be attractive where there is a practical external route. Recirculation may suit a location where that route is difficult, provided you understand its limitations and budget for the correct filters.
| Arrangement | Main benefit | What to check |
|---|---|---|
| Ducted extraction | Discharges cooking air and moisture outdoors | Duct route, outlet position, installation work and replacement air |
| Recirculation | Avoids the need for an external exhaust duct | Compatible kit, odour filter costs and separate room ventilation |
| Convertible model | Offers a choice of operating arrangements | Which accessories are included and performance in the selected mode |
Match the hood style to the kitchen
A wall-mounted chimney hood makes the cooking area a visible feature. An integrated or canopy model can sit more discreetly within cabinetry. Neither is automatically better; the sensible choice depends on space, access and the look you want.
For an island hob, consider how a suspended or ceiling-mounted hood will affect sightlines. Have the installer check the structure, route and servicing access before committing to a sleek ceiling design. These decisions are easier before the ceiling is finished.
Downdraft extractors and venting hobs are another option, but they need careful planning within the units below. Ask what space remains for drawers and how the air will be routed. Do not assume an appliance photograph shows everything required behind the cabinets.
Check dimensions beyond the width
The hood must be suitable for the hob beneath it. Give the installer both model numbers and have them check the installation instructions together, including clearance, positioning and any restrictions. There is no single fitting height that covers every hood and hob combination.
Also check cabinet doors, ceiling height and the chimney section’s adjustment range. When replacing a hood, the new casing may reveal old fixing holes or an unfinished strip of wall. Allow for decorating or splashback work if necessary.
If possible, stand in front of a display model. Reach the controls, look at the hob lighting and see whether the hood projects into your normal working position. These small things matter more after a month of cooking than they do in a product photograph.
Compare useful performance and noise
Tell the supplier about your cooking habits: occasional simmering makes different demands from frequent frying or cooking on several rings. Ask which operating setting is likely to suit normal use in your kitchen.
Compare published airflow and noise figures on the same basis. A low-speed noise figure alongside another model’s maximum figure is not a fair comparison. Check whether the quoted performance includes a temporary boost setting and whether it applies to your chosen operating mode.
In an open-plan room, listen to a demonstration if available. A showroom will not reproduce your home exactly, but it can help you decide whether a particular sound or control layout would irritate you.
A larger headline airflow figure is not a guarantee of a better result. The installed arrangement matters too, so ask the fitter to explain any limitations before ordering.
Agree the duct route before fitting day
For extraction outdoors, have the installer specify the duct size and route required by the manufacturer. Restricted or poorly planned ducting can undermine the result. Do not assume an old duct is suitable simply because the previous hood used it.
Ask where the outlet will appear outside and how it will be finished. Check whether cupboards, boxing or other work are needed to conceal the route. Include access for future maintenance in the discussion.
Extraction must not discharge into a flue serving a gas or other fuel-burning appliance. Tell the installer about any stove, open fire or other combustion appliance so they can assess ventilation and safe operation together. Any electrical alterations should be arranged with a suitably qualified electrician.
Look at cleaning and filter costs
Try removing the grease filter on a display model, or ask to see how it releases. A filter that is awkward to reach is more likely to become a neglected chore.
Follow the appliance instructions for cleaning. Some metal filters are dishwasher suitable, but that is not a universal rule. Recirculating models also need the specified odour filter, with replacement or regeneration carried out as directed for that exact product.
Check the replacement filter price and availability before buying. Include the recirculation kit if it is sold separately. A lower appliance price can be less appealing once the accessories and ongoing upkeep are included.
Get a complete installed quote
Costs vary by property, specification and location. Replacing a hood using a suitable existing connection is a different job from creating a new external duct route or altering cabinetry.
Ask each quote to identify:
- The exact hood model and operating mode.
- Ducting, external outlet or recirculation accessories.
- Electrical work and any required testing or documentation.
- Cabinet alterations, boxing, drilling and making good.
- Removal of the old appliance and packaging.
- VAT where applicable, exclusions and workmanship cover.
Agree who supplies the appliance and handles damage or faults. Before the installer leaves, ask for a demonstration of the controls, lighting and filter removal, and keep the manuals and product details.
Frequently asked questions
Can I replace my hood with one of the same width?
Width is only one check. The fixing points, depth, clearances, electrical connection and duct arrangement may differ. Have the replacement assessed before ordering.
Does a recirculating hood remove condensation?
It filters air and returns it to the room rather than carrying moisture outdoors. Persistent condensation needs the kitchen’s ventilation and moisture sources assessed.
Are smart controls worth paying for?
They can be convenient if you will use them. Check compatibility with your hob and prioritise suitable performance, comfortable noise levels and easy cleaning first.
Can I reuse the existing ducting?
Possibly, if its size, condition and route suit the new hood’s requirements. Ask the installer to check rather than treating reuse as automatic.
