Since its founding in 2019, the West Lothian-based firm has evolved into a national brand with 12 trade counters across the UK, a reputation for quality, service and reliability and a portfolio of clients which includes nationally renowned brands like B&Q. Since 2019 the company has grown its headcount from 26 to 212 employees – an increase of 715% - and raised revenue by 608%.

As part of its growth strategy, the new online division expands the company’s service offering, allowing additional markets to be reached and customers to log their orders at a time convenient to them. In practical terms, this digital presence speeds up the time between order and delivery.

Due to demand, the business has also launched an installation service for the public and energy sectors, with Window Supply Company’s investment in cutting-edge manufacturing and innovation meaning it can now meet these evolving needs. The team is currently onsite working for major contractors in the new build and retrofit market in Scotland, which includes social and affordable housing.

The company’s success follows a multi-million-pound investment from BGF, the UK and Ireland’s most active growth capital investor, in 2020.

The business recently launched a new product, Zero90, designed to achieve industry-leading thermal performance. Zero90 helps landlords dramatically improve the energy efficiency of their housing stock by cutting carbon emissions and reducing fuel consumption for tenants at a time when energy costs remain high.

Window Supply Company has also expanded its senior team by welcoming Colin Joyce as business development manager, strengthening its position in the public sector.

Duncan Murray, CEO of Window Supply Company, said: “The rapid expansion of our business is a testament to the high-quality service and innovative manufacturing we offer our customers, as well as the hard work of our team.

“The huge demand we’ve seen has spurred the transition of Window Supply Company into new business areas, each with their own compelling offering. Our new public and energy sector branch allows us to address important concerns in these key areas - such as in the new build or affordable housing markets - and our online platform enables us to tap into new markets and enhance the accessibility of our services.

“Despite a tough operating environment, we’re really proud of how far we’ve come since our beginnings in 2019, and BGF’s support has been invaluable. There’s a lot more to come as we enter the next phase of our growth strategy and continue to identify opportunities on the horizon.”

Graham Clarke, regional portfolio partner at BGF, said: “BGF has supported Window Supply Company since 2020, and we’re pleased to see the business achieving these important milestones as part of its ongoing growth strategy.

“The team has broadened the business model in response to the level of demand from existing and new customers, setting up a strong platform for future growth.”
