Martyn Day MP pays Window Supply Company HQ a visit!

Martyn Day, SNP Spokesperson for Health and serving MP for Linlithgow and Falkirk visited Window Supply Company’s (WSC) new head office and manufacturing site in Whitburn to hear about the company’s phenomenal growth to date, learn more about their support in the local community and discuss plans for the future.

Mr. Day was welcomed by WSC Directors, Duncan Murray, and Martin Linden on Thursday last week at the company’s head office in Murraysgate Industrial Estate. Since setting up the business WSC has very quickly become the largest manufacturer of uPVC windows and doors for trade in Scotland, now positioned as one of the largest trade manufacturers in the UK.

The WSC story so far

WSC started their journey in March 2019 in a 22,000 sq. ft manufacturing site in Livingston’s Houstoun Industrial Estate, with a team of just 26. The business very quickly outgrew the original site and moved to the much larger 105,000 sq. ft. facility in Whitburn to support further growth. Relocating in March 2022 to the former locally renowned Levi’s factory and transforming the almost derelict building into the bustling factory Mr Day visited. The relocation has brought employment opportunities and economic growth to a town still suffering the blow of the closure of the original Levi’s factory which once employed over 500 people.

WSC now employs over 168 people nationwide across their manufacturing facility in Whitburn and trade counters in Aberdeen, Bellshill, Dundee, Inverness, Kilmarnock, Lincoln, Livingston, Loanhead, Manchester and Sheffield. Duncan Murray advises Mr. Day that incredibly, WSC’s success has been achieved under the backdrop of a global pandemic and whilst the market has dropped by 25% this year, the company records 41% growth.


During the visit Mr, Day was invited to tour the factory by Operations Director Martin Linden who highlighted the work WSC do to ensure minimal impact on the planet. All uPVC offcuts produced in the factory as part of the manufacturing process are recycled. All waste uPVC and cardboard are packaged and bailed in the factory and sent to be recycled. Recycling facilities are provided at all trade counters so customers can bring back old window and door waste for recycling. The old uPVC frames and glass are recycled to produce new uPVC and glass products.

Community & charity work

Duncan Murray shared the work WSC do within the local community showcasing the framed football shirt of the local Whitburn 2009 Under 15’s football team of whom the company are the proud sponsors. The WSC team were delighted the boys picked up a cup double this year by lifting The League Cup and The County Cup. WSC regularly take part in fundraising activities to raise funds for charities which do vital work in the community. Raising an impressive £5000 for the Scottish Association for Mental Health when so many were impacted by the pandemic. Some members of the team are currently fundraising for the fantastic MacMillan Cancer Support by taking part in the Rob Roy Mighty Hike in the Trossachs next month.

Plans for the future

Updating Mr. Day on WSC plans for the future, Duncan Murray spoke of the company’s commitment to providing the highest quality products and services with recent investment of £200K of CNC aluminium window and door fabrication machinery. This allows the company to fabricate products they currently buy in and provides opportunity for further expansion. WSC seeks to capitalise on their exponential growth to date by expanding their trade counter network with new branches planned South of the border.

Mr Martyn Day, MP for Linlithgow and Falkirk says ‘Thank you to Window Supply Company for inviting me to their site in Whitburn. Always great to hear about a local business who, despite a challenging climate, are developing, growing, and thriving, while providing skilled jobs for local people’.
