Looking to breathe new life into your home with a small kitchen extension with a skylight? At KT5 Construction, we specialise in beautifully crafted kitchen extensions across London and Surrey. Skylights are one of the most effective ways to enhance space, natural light, and style—perfect for compact layouts. In this guide, we’ll explore the benefits, design ideas, and practical tips for planning a skylight kitchen extension, along with cost insights and regulations you should know.

Why Choose a Skylight for Your Small Kitchen Extension?

Adding a skylight to a kitchen extension brings a host of benefits:

• • Maximised natural light – Perfect for small spaces that often feel dark or cramped.

  • Enhanced energy efficiency – Reduces the need for artificial lighting during the day.

  • Improved ventilation – Ideal for steamy kitchen environments.

  • Visual impact – Skylights create architectural interest and make your kitchen feel taller and more open.

Design Ideas for a Small Kitchen Extension with Skylight

Flat Roof vs. Pitched Roof Skylights

• • Flat Roof Options: More cost-effective and modern, suitable for rear or side return extensions. Glass lanterns or fixed skylights are commonly used.

  • Pitched Roof Options: Often paired with traditional homes, they blend well with period architecture. Roof lanterns add elegance and maximise vertical space.

Skylight Placement Matters

Positioning skylights above worktops or dining areas can enhance task lighting and ambience. East-facing skylights work well for breakfast nooks while west-facing are ideal for evening gatherings.

How Much Does a Small Kitchen Extension with Skylight Cost?

• • Skylight Installation: £850–£1,200 per unit for glass panels.

  • Glazing Costs: Range from £400 to £3,000 depending on size and quality.

  • Total Extension Cost: Typically starts from £25,000–£35,000 for a small extension, but this varies based on materials, location, and layout.

Planning Permission & Building Regulations

Many small kitchen extensions with skylights fall under permitted development—meaning you might not need full planning permission. However, be mindful:

• • Skylights must not protrude more than 150mm above the existing roofline.

  • The materials should be in keeping with the original house design.

They can—but solar control glazing and ventilated options help regulate indoor temperatures.

Not necessarily. Low-maintenance coatings minimise cleaning and prevent grime build-up.

Yes, if your roof structure supports it and planning regulations are met.
