In an era of rising energy costs and increasing focus on wellbeing, skylights are proving their worth in modern homes and buildings. Far from mere windows on the roof, today's skylights offer a blend of practicality and style that can transform living spaces and slash energy bills.

Let There Be Light (and Savings)

The impact of natural light on both mood and energy consumption is well-documented. Dr Alan Lewis, an environmental psychologist at the University of Manchester, notes: "Exposure to daylight is crucial for regulating our circadian rhythms. Homes with ample natural light often report higher occupant satisfaction and wellbeing levels."

But it's not just about feeling good. James Barker, energy efficiency consultant at the Energy Saving Trust, points out the financial benefits: "Our data shows that homes with well-placed skylights can reduce their reliance on artificial lighting by up to 70% during daylight hours. Over a year, that translates to significant savings on energy bills."

Choosing Wisely: More Than Just a Hole in the Roof

Selecting the right skylight involves more than just picking a size and shape. Paul Trace, managing director at Stella Rooflight, emphasises the importance of quality: "A poorly chosen or installed skylight can lead to heat loss and condensation issues. We always advise clients to look for units with excellent U-values and proper installation techniques."

Key considerations include:

Size and placement

The National Association of Rooflight Manufacturers (NARM) recommends that roof lights cover 15-20% of the floor area in living spaces for optimal natural light.

Glazing options

The choice of double-glazed or solar-control glass affects insulation and light transmission.

Ventilation

Opening skylights can significantly improve air circulation, crucial for maintaining a healthy indoor environment.

Navigating the Red Tape

Building regulations can be a minefield, but they're there for good reason. Sarah Eberle, a chartered architect and RIBA member, advises: "Always check local planning requirements before installation. In conservation areas or listed buildings, you may need special permissions. It's better to know upfront than face issues down the line."

In the UK, Part L of the Building Regulations sets the standard for energy efficiency. As of 2022, new skylights must achieve a U-value of 1.4 W/m²K or lower to be compliant.

Innovation on the Horizon

The skylight market needs to stand up. Tom Jarman, innovation lead at BRE (Building Research Establishment), hints at exciting developments: "We're seeing prototypes of smart skylights that adjust their opacity based on sunlight intensity and indoor temperature. The potential for integration with home automation systems is immense."

The Bottom Line

Skylights offer a rare combination of aesthetic appeal and practical benefits. As energy costs continue to climb and awareness of the importance of natural light grows, they're likely to become an increasingly common feature in UK homes.

Richard Moss, quantity surveyor and cost consultant, offers this final advice: "While the upfront cost of quality skylights can be significant, the long-term savings in energy bills and the boost to property value often make them a sound investment. As with any home improvement, research and don't cut corners on quality."
