Our Parent Group
The Interconnect Solutions Group is part of Diploma PLC — a FTSE 100 value-add solutions group built around specialist, entrepreneurial businesses supplying critical products to demanding markets worldwide.
The Diploma Group
Diploma PLC is a FTSE 100 company built around a group of specialist, entrepreneurial businesses that supply critical products and services to customers operating in technically demanding markets. Founded in 1931 and listed on the London Stock Exchange since 1960, Diploma has grown through disciplined acquisition and strong organic performance into one of the UK's most respected value-add distribution groups.
Each Diploma business operates with a high degree of autonomy — retaining its own identity, customer relationships and specialist expertise — while benefiting from the stability, scale and capital of a large, multinational group. ISG joined Diploma and has continued to grow as part of the Controls sector.
End Market Exposure
Diploma's businesses serve markets that grow structurally over time — aerospace, defence, medical, energy and industrial sectors driven by long-term trends rather than short economic cycles.
Geographic Penetration
Existing products and relationships extended into new geographies — growing revenue without growing complexity. ISG's US, European and Czech businesses are a direct expression of this strategy.
Product Extension
Deepening the product offer within existing customer relationships — adding adjacent categories that build on established technical credibility and long-standing supply partnerships.
“A group of entrepreneurial businesses, powered by brilliant people and strong leadership — each operating independently while benefitting from the scale and resources of a large, multinational group.”
