Edinburgh-based Gecko Glazing manufactures secondary glazing panels designed to reduce heat loss in residential and historic properties.
Edinburgh-based Gecko Glazing has secured £150k in a funding round led by British Design Fund. The capital will be directed towards enhancing production facilities, acquiring new equipment, and advancing product and business development strategies.
Founded in 2020 by Gareth Claase, the start-up offers clear acrylic panes placed within existing window frames to reduce domestic heat loss and carbon emissions by up to half. The system provides a lower-cost alternative to conventional double glazing without damaging period features or listed buildings.
The investment arrives as UK households face rising energy costs and mounting pressure to improve domestic thermal efficiency.
From the founder
"Rocketing fuel prices are plunging many households into fuel poverty, which highlights the need for easier, more affordable ways to reduce window heat loss. Our Gecko Panes provide provide an affordable and easy way to reduce heat loss and emissions from the UK’s poorly insultated housing stock. We aim to install Gecko Panes in thousands of homes per year, not just in the UK, but in key export markets too."

Investor perspective
"We’re delighted to welcome Gecko Glazing to the BDF portfolio. The UK is currently facing its worst energy crisis in decades, as well as a climate emergency which has seen the country commit to achieving net zero emissions by 2050. Low cost solutions like this – which can significantly reduce energy costs while quickly improving the carbon footprint of inefficient homes – have never been more important."
