Founded in 1973, Sovereign Group is regarded as a pioneer in the UK PVC‑U market and has built a strong reputation over the years. The company serves Commercial clients within social housing, local authorities, schools, and regional housebuilders across the UK. Sovereign is headquartered in Nelson, Lancashire, where its manufacturing facility is located, and employs around 170 people. The majority owners are Gordon Weir, Managing Director, and David Fitton, Operational Director.
The acquisition further strengthens Inwido’s presence in the UK and adds a well‑established platform within social and affordable housing renovation – a segment characterized by long‑term demand, high quality requirements and high barriers to entry.

The company is an excellent strategic fit for Inwido and complements our existing UK operations. We see attractive opportunities to support continued growth while preserving Sovereign’s strong local identity and customer focus”, says Fredrik Meuller, President and CEO of Inwido.

“Becoming part of Inwido gives us a strong long‑term owner with extensive experience in our industry. This partnership will allow us to continue developing our offering, invest in our operations and create new opportunities for our employees and customers”, says Gordon Weir, Managing Director of Sovereign Group.
