How much value do kitchen extensions add to a property?

A kitchen extension in the UK can significantly increase a house’s value, with estimates generally ranging from 5% to 20%.
Here’s a breakdown of what various sources suggest:
Average Increase:
Many sources indicate a range of 6-10% or 10-15% for a well-designed kitchen extension. Some suggest a single-storey rear extension (often used for kitchens) can add 5-8%. A study by Zopa specifically found that kitchen extensions can increase a home’s value by 10-20%. One expert even suggests a “conservatory kitchen extension” could add up to 25% if well-designed.
Return on Investment (ROI):
A kitchen extension can offer a solid ROI, with figures cited around 51% or even 67%. This means you could recoup a significant portion of your investment when selling. Some sources suggest an average ROI of 70%+ after 5 years.

Factors influencing the value added:

Quality of construction and finishes:
High-quality materials and workmanship are crucial. Design and functionality: A well-designed layout, good flow, and plenty of natural light (e.g., with rooflights or bi-fold doors) are highly appealing.
Size and use of the extension:
A larger, practical, and usable space will generally add more value. Integration with the existing home: The extension should feel like a seamless part of the house. Location and local market demand: In high-demand areas, an extension is likely to add more value. It’s important not to over-develop beyond the “ceiling price” for properties in your specific neighbourhood.
Additional features:
Incorporating elements like a kitchen island, utility room, pantry, energy-efficient appliances, or connecting the kitchen to the garden can further boost appeal and value. Existing kitchen size: Extending a particularly small or narrow kitchen will likely add more value than simply enlarging an already decent-sized one.

Potential pitfalls that can devalue your home:

Poor design or cheap finishes:
This can actually deter buyers.
Lack of cohesion:
The extension should blend with the rest of the house.
Oversized structures:
Taking up too much valuable garden space can negatively impact value, especially in urban areas where outdoor space is limited.
Ignoring planning advice:
Always work with professionals and ensure compliance with local regulations.
In summary:
A well-planned and executed kitchen extension is generally considered a good investment in the UK, offering a significant boost to your property’s value.
