DIY Guide: Installing Your Cooker Hood Like a Pro
Installing a cooker hood is a fantastic way to improve your kitchen environment by removing cooking fumes, smoke, and grease. It helps keep your kitchen cleaner, fresher, and less prone to lingering odors. While professional installation is always an option, fitting a cooker hood yourself can save you money and provide a sense of accomplishment. This comprehensive guide will walk you through the entire process, from choosing the right hood to the final connection and testing.
Before You Begin: Planning and Preparation
Before you even think about picking up a screwdriver, careful planning and preparation are crucial for a successful cooker hood installation. This involves several key steps:
1. Choosing the Right Cooker Hood
* Type of Cooker Hood: Cooker hoods come in various types, each with its own advantages and disadvantages. The most common types include:
* Ducted Hoods: These hoods extract air and vent it outside through a duct. They are generally more effective at removing odors and grease but require a duct to be installed.
* Recirculating Hoods: These hoods filter the air through charcoal filters and recirculate it back into the kitchen. They are easier to install as they don’t require ducting but are less effective at removing odors and grease and require periodic filter replacement.
* Integrated Hoods: Also known as built-in or concealed hoods, these are integrated into kitchen cabinets, offering a seamless and discreet look.
* Chimney Hoods: These are mounted on the wall above the cooker and have a decorative chimney that houses the ducting.
* Island Hoods: Designed for kitchen islands, these hoods are suspended from the ceiling.
* Size and Extraction Rate: The size of the cooker hood should be at least the same width as your cooker. The extraction rate (measured in cubic meters per hour – m³/h) determines how much air the hood can move. A higher extraction rate is generally better, especially for larger kitchens or frequent cooking. A general rule of thumb is to multiply the kitchen’s volume (length x width x height) by 10 to determine the minimum extraction rate required. For example, a kitchen that is 4m long, 3m wide, and 2.5m high has a volume of 30m³. Multiplying this by 10 gives you a minimum extraction rate of 300 m³/h.
* Features: Consider features like lighting, variable speed settings, and noise level when choosing your cooker hood. LED lighting is energy-efficient and provides good illumination. Variable speed settings allow you to adjust the extraction rate depending on your cooking needs. A lower noise level is generally preferred for a more pleasant cooking experience.
2. Gathering Your Tools and Materials
Having the right tools and materials readily available will make the installation process much smoother. Here’s a list of essential items:
* Cooker Hood: Obviously, the cooker hood itself.
* Drill with various drill bits: Including masonry bits if you’re drilling into brick or concrete.
* Screwdriver Set: Including both Phillips head and flat head screwdrivers.
* Measuring Tape: For accurate measurements.

3. Checking for Obstacles and Services
Before drilling any holes, check for any hidden pipes, cables, or other services in the wall. Use a pipe and cable detector if necessary. Ensure there is sufficient space for the hood and ducting (if applicable) without obstructing any existing fixtures or fittings. Make sure you have easy access to an electrical outlet or can safely run a cable to a suitable power source.
4. Safety First: Disconnect the Power
This is absolutely critical! Before you start any electrical work, disconnect the power supply to the cooker hood circuit at the main fuse box or circuit breaker. Use an electrical tester or multimeter to confirm that the power is off before touching any wires.
Step-by-Step Installation Guide
Now that you’ve planned and prepared, it’s time to get down to the actual installation. Follow these steps carefully:
Step 1: Marking the Mounting Position
