What is Concentration?

In a business context, concentration refers to the extent to which a company’s revenue, market share, or other key metrics are dominated by a small number of customers, products, or markets. For a UK audience, understanding business concentration is crucial for managing risks, making strategic decisions, and ensuring sustainable growth.


Key Aspects of Concentration in Business:

  1. Client Concentration:
    • Definition: Client concentration occurs when a significant portion of a company’s revenue comes from a small number of clients. High client concentration means that losing one or more of these clients could severely impact the business’s financial health.
    • Implications:
      • Risk Management: High client concentration increases financial risk. If a major client decides to switch suppliers or goes out of business, the impact on revenue can be significant.
      • Negotiation Power: Clients who contribute a large share of revenue may have greater leverage in negotiations, potentially leading to less favourable terms for the business.
    • Strategies to Mitigate Risks:
      • Diversification: Actively seek to expand the client base to reduce dependency on a few major clients.
      • Strengthening Relationships: Develop strong, long-term relationships with key clients to enhance loyalty and reduce the risk of losing them.
      • Credit Control: Implement robust credit control measures to manage and monitor client payments and creditworthiness.
  2. Product Concentration:
    • Definition: Product concentration refers to a situation where a large portion of a company’s revenue comes from a limited number of products or services.
    • Implications:
      • Market Vulnerability: High product concentration can make a company vulnerable to market changes, such as shifts in consumer preferences or technological advancements.
      • Innovation Pressure: Relying heavily on a few products increases pressure to innovate and continuously improve those products to stay competitive.
    • Strategies to Mitigate Risks:
      • Product Diversification: Develop and market new products or services to reduce reliance on a few key offerings.
      • Market Research: Conduct regular market research to identify emerging trends and opportunities for product development.
      • Customer Feedback: Use customer feedback to improve existing products and develop new ones that meet market needs.
  3. Market Concentration:
    • Definition: Market concentration occurs when a small number of companies hold a large market share within a particular industry or sector.
    • Implications:
      • Competitive Dynamics: High market concentration can reduce competition, leading to higher prices and reduced innovation.
      • Regulatory Scrutiny: Markets with high concentration may attract regulatory scrutiny and potential antitrust actions to ensure fair competition.
    • Strategies to Mitigate Risks:
      • Competitive Analysis: Regularly analyse competitors and market conditions to identify opportunities and threats.
      • Strategic Alliances: Form alliances or partnerships to enhance market presence and competitive advantage.
      • Regulatory Compliance: Stay informed about regulatory changes and ensure compliance to avoid legal issues.


A UK-based technology company generates 60% of its revenue from just two clients. This high client concentration poses significant risks if either client reduces their business or switches to a competitor.

  • Risk Mitigation Strategies:
    • Diversification: The company targets new sectors and smaller clients to reduce dependency on the two major clients.
    • Relationship Building: The company invests in building stronger relationships with existing clients through excellent customer service and regular engagement.
    • Innovation: The company develops new products and services to attract a broader client base and reduce product concentration.


Understanding and managing concentration in a business context is essential for UK companies to mitigate risks and ensure sustainable growth. Whether it’s client concentration, product concentration, or market concentration, businesses need to adopt strategies to diversify, innovate, and strengthen relationships to maintain financial stability and competitiveness. Regular monitoring and proactive management can help businesses navigate the challenges associated with high concentration levels.
