Planning a new kitchen is exciting, but without the right preparation, it can quickly become stressful, expensive or disappointing. At Fully Fitted Kitchens, we’ve seen it all – the last-minute layout changes, forgotten sockets, awkward clearances, and those all-too-common regrets that could have been avoided with better planning.
To help you get it right first time, here are 10 of the most common fitted kitchen planning mistakes, and how to avoid them.
1. Not Understanding Your Workflow
Every kitchen needs to function well, not just look good. Many people focus on style over practicality and overlook how they actually use their kitchen. Always plan with the kitchen “working triangle” in mind – the route between your sink, cooker and fridge should be logical and efficient.
Failing to consider your daily routines can result in a kitchen that’s beautiful but awkward. Before finalising your layout, take time to think about your cooking habits, storage preferences and how you use the space.
2. Ignoring the Importance of Lighting
Lighting is often treated as an afterthought, but it has a major impact on how a kitchen feels and functions. A well-lit kitchen combines task lighting (for food prep), ambient lighting (for mood), and accent lighting (for design features).
Position ceiling lights to reduce shadows over key areas like worktops, hobs and sinks. Consider under-cabinet lighting and don’t forget natural light sources when placing units or tall appliances.

3. Overlooking Storage Options
Lack of storage is one of the top regrets homeowners have post-installation. Don’t just think about cupboard space — think smart storage: pull-out racks, deep drawers, corner carousels, integrated bins, and vertical tray storage.
You’ll thank yourself later if everything has a place. Poor storage planning leads to cluttered worktops and frustration over time.
4. Choosing Style Over Function
We all love a sleek design, but make sure it works in real life. Glossy finishes might look great in a showroom but show fingerprints easily. Handle-less cabinets can be tricky to use for some people. Open shelving may look minimal, but it demands constant tidying.
Balance visual appeal with how you’ll use your kitchen day-to-day.
5. Skipping the Measuring Details
Poor measuring leads to big problems. Gaps, misaligned units, and appliances that don’t fit properly are expensive to correct once the installation has started.
At Fully Fitted Kitchens, our design process includes a professional site survey to double-check every measurement before manufacturing begins. Accuracy is key, especially in older homes where walls may not be square.
6. Not Planning for Appliances Early Enough
Too often, people choose appliances last, but it should be one of the first steps. Appliance dimensions affect cabinet sizes, layout choices, and ventilation requirements.
Choose your hob, oven, fridge and dishwasher early and let your kitchen design work around them. You don’t want to end up with a microwave with nowhere to go.
7. Overloading the Space
Trying to fit too much into a kitchen leads to a cramped, uncomfortable layout. This often happens in small kitchens, where people try to force in islands, peninsulas or extra cupboards.
Negative space matters. Leave enough room to open drawers, walk comfortably and work efficiently. Bigger isn’t always better – a well-planned compact kitchen will always outperform a cluttered large one.

8. Forgetting About Ventilation
Proper ventilation is vital, especially in open-plan kitchens. A good extractor hood not only removes cooking smells and moisture, but also protects your units and walls from grease build-up.
Plan early for ducting routes and avoid cheap recirculating fans in larger spaces. They rarely perform well long-term and can impact air quality in your home.
9. Neglecting Electrical Planning
It’s easy to forget how many sockets your kitchen needs – until you don’t have enough. Think beyond appliances. Where will the kettle go? Will you want to charge a phone or plug in a blender? Under-cabinet sockets, USB outlets and pop-up ports are worth considering.
Position switches and power points early in the design stage. It’s cheaper and easier than retrofitting them once units are installed.
10. Choosing the Wrong Installer
Even the best kitchen design will fall apart with poor installation. Fitted kitchens require precision, experience and attention to detail. A rushed or careless job can leave you with uneven units, gaps, and alignment issues.
Choose a local, reputable installer with proven experience and a portfolio of work. Which? offers a trusted guide to finding the right kitchen company, including what questions to ask before signing a contract.
