Why window shading solutions are becoming a heatwave essential

 The hot and dry summer of 2026 has given the UK plenty of reminders that overheating is no longer an occasional concern. The UK’s Met Office has indicated that this summer is the hottest on record, with five widespread heatwaves and 40 days of temperatures above 30C (86F), breaking the previous record of 34 days. 

The timing of the latest BBSA Trends & Solar Shading Report is consequently highly significant. Its analysis of Google Trends data reveals that UK search interest in “external blinds” reached an all-time high in July 2026, with a score of 100. That was 245 per cent higher than July 2025 and more than 2.5 times the previous July peak, recorded in 2022. 

More revealing is the relationship between searches for external blinds and searches for heatwaves. Over the past 24 months, the two have followed a remarkably similar pattern, with both reaching 100 in July 2026. 

The data doesn’t prove that hot weather causes people to buy shading; however, it does show that interest in external blinds rises sharply when heatwave concerns rise. Shading is increasingly part of the conversation when people are looking for ways to manage excessive heat. 

Shading is becoming a broader category

The report also reveals that homeowners are looking beyond conventional blinds. Related searches include external shutters, thermal blinds, outdoor blinds, external Venetian blinds and external awnings. 

That reflects the range of challenges created by excessive solar radiation. A south-facing window may need a different approach from a large glazed extension. The most appropriate solution depends on the property, glazing, orientation and how the room is used. 

Why external shading deserves attention

The BBSA’s guidance on overheating highlights the importance of preventing solar heat gains before they enter a building. External shading is particularly effective because it shades the glazing from the exterior, rather than attempting to manage solar energy after it has passed through the glass.  

This can be particularly valuable where homes have large areas of glazing or windows exposed to strong sunlight. The right external shading system can help reduce overheating while retaining useful natural light and views. 

There is also a role beyond the hottest months. The correct shading can be adjusted according to weather conditions, allowing homeowners to manage sunlight and solar gain throughout the year. BBSA guidance also highlights the potential energy-saving role of shading in reducing unwanted heat loss throughout the winter. 

Choosing the right shading solution

There is no single answer for every property. The orientation of the glazing is an important starting point, as is its size and specification. How a room is occupied matters too. 

External blinds can offer precise control at individual windows, while shutters provide another option where their appearance and functionality suit the property. Awnings can be particularly useful where shading is required over larger areas of glazing or an outdoor living space. 

Movable external shading comes in a wide range of colours, styles and control options, with solutions to suit different homes, requirements and budgets. 

For homeowners considering external solar shading, professional advice is therefore valuable. A specialist can assess the building and recommend a solution that balances performance, appearance, operation and longevity. 

Shading is part of the cooling conversation

The report puts the growth in shading into useful perspective. As previously stated, in July 2026, searches for ‘external blinds’ increased by 245 per cent year-on-year, compared with 191 per cent for ‘portable air conditioners’, 124 per cent for ‘air conditioning’ and 100 per cent for ‘air-conditioning installation’. However, this doesn’t mean shading has overtaken air conditioning. Air conditioning remains considerably larger in absolute search interest. What the figures demonstrate is that homeowners are increasingly considering different ways of responding to heat, with shading forming part of that wider response. 

For anyone whose home becomes uncomfortably hot during periods of intense sunshine, external shading solutions deserve consideration before the next heatwave arrives. 

The latest BBSA data suggests that many homeowners are already starting that conversation when the temperature rises. With professional advice, they can make sure the solution they choose is appropriate for their property and capable of delivering the functionality they need. 

Find the right shading solution

If your home becomes uncomfortably hot during periods of strong sunshine, a BBSA member can help you identify the most appropriate shading solution for your property. From external blinds and shutters to awnings and other solar shading solutions, professional advice can help you achieve effective control of sunlight, glare and indoor temperatures.
