10 Common Kitchen Installation Mistakes and How to Avoid Them

Learn from the experts about costly kitchen installation mistakes that can derail your project. Avoiding these common pitfalls will save you time, money, and stress.

A kitchen installation is a significant investment, and mistakes can be expensive to fix. After thousands of installations, we've seen these errors repeatedly. Here's how to avoid them.

1 Not Measuring Accurately

The Problem: Incorrect measurements lead to units that don't fit, wasted materials, and expensive reorders.

The Solution: Measure at least twice, from multiple points. Account for skirting boards, pipes, and electrical outlets.

2 Ignoring the Working Triangle

The Problem: Poor layout planning creates inefficient workflows. The "working triangle" between sink, hob, and fridge should total 4-9 meters.

The Solution: Position these three key elements so you're not constantly crossing the kitchen.

3 Insufficient Electrical Planning

The Problem: Not enough sockets, or sockets in awkward positions. Modern kitchens need power for countless appliances.

The Solution: Plan for at least 6-8 double sockets. Consider USB charging points and pop-up sockets in islands.

4 Inadequate Storage Planning

The Problem: Not thinking through storage needs until after installation. You realize too late that you have nowhere for tall items.

The Solution: Consider pull-out larders, corner carousel units, drawer dividers, and pan drawers.

5 Wrong Height Worktops

The Problem: Standard worktop height is 90cm, but this doesn't suit everyone. Working at the wrong height causes back pain.

The Solution: If you're significantly taller or shorter than average, consider custom height worktops.

6 Poor Lighting Design

The Problem: Relying on a single ceiling light leaves work areas in shadow.

The Solution: Layer your lighting - combine ambient, task, and accent lights. LED strips under wall units illuminate worktops perfectly.

7 Skimping on Ventilation

The Problem: Choosing an underpowered extractor leads to lingering cooking smells and potential mold growth.

The Solution: Invest in a properly sized extractor that vents outside.

8 Not Allowing for Appliance Ventilation

The Problem: Integrated appliances fitted too tightly overheat and fail prematurely.

The Solution: Always follow manufacturer specifications for appliance clearances.

9 Choosing Style Over Functionality

The Problem: Falling in love with trendy features that don't suit how you actually use your kitchen.

The Solution: Be honest about your lifestyle. Style is important, but it shouldn't compromise usability.

10 Hiring Unqualified Installers

The Problem: Choosing the cheapest quote without checking qualifications or insurance.

The Solution: Always use qualified professionals. Check that electricians are Part P registered and the company carries full insurance.
