What Sunsquare does

Sunsquare Limited is a UK-based designer and manufacturer of premium skylights, roof lanterns, and rooflights, founded in 2004 and headquartered in Bury St Edmunds, England. The company operates a state-of-the-art production facility with CNC machining and an in-house CAD design team, producing around 165 different skylight combinations across its SkyView (fixed), Aero (electric opening), Horizon (walk-on), and Pyramid (30-degree pitch) product families, alongside bespoke custom skylights. Core technology centres on thermally broken aluminium frames with polyamide insulating sections that achieve U-values as low as 0.5 W/m²K, laminated safety glass bonded with structural adhesive meeting CWCT TN67 non-fragile standards, and the Smartsquare smart switch integrating with Siri, Amazon Alexa, and Google Home.

The business operates a direct-to-customer sales model supported by telephone, email quote requests with CAD drawing uploads, an owned UK delivery fleet, factory collection, and a dedicated professional installation service covering London and the South East.

Sunsquare targets horizontal customer segments including homeowners, architects, builders and contractors (primary), as well as commercial/hospitality, education, and public sector projects (secondary), distributed across the UK domestic market. The company holds the BSI Kitemark certification as the UK's first flat roof skylight manufacturer accredited under BS 6375-1:2009, plus ISO 9001:2015 and ISO 14001 certifications.
