We invest in Western European mid-market companies

Duke Street Private Equity has been investing in mature, mid-market West European businesses for over twenty years, concentrating our investment strategy on four sectors: Consumer, Healthcare, Industrials & Engineering and Services. Typically we invest in companies with an enterprise value of between £50m - £250m. Our strategy is based on our ability to identify unique opportunities and add value to each business we acquire. We aim to transform the prospects of the companies that we invest in.

Origination beyond the obvious

We focus our efforts on transactions developed on an exclusive basis. We actively seek complex deals which other investors may avoid if we think they have underlying growth potential.

Value creation

Our mission is to accelerate the growth of the companies that we buy. We help our companies grow both organically and through acquisition.

Supportive Structure

We have developed a robust approach to building relationships between ourselves, the CEOs of our portfolio businesses and our Operating Partners.

Sector focus

We believe sector knowledge is critical, which is why we have dedicated teams focusing on our four core sectors. This, alongside the deep industry experience of our Operating Partners, has allowed us to create a proven track record of successfully building companies.

We invest in companies with strong brands serving consumers across multiple channels

We have extensive experience in the consumer sector: in restaurants with wagamama, in the gaming sector through our investment in companies such as Gala Bingo, Sporting Index and Leisure Link. In leisure, we have invested successfully in both niche hotel operators and fitness and leisure businesses. Two of our investments in particular – SandpiperCI and The Original Factory Shop – display our willingness to back retail management teams with ambitious growth plans, even at a time when the sector as a whole was experiencing tough trading.

We also have a wealth of experience of working with management teams in consumer branded products. At Simple, we backed an ambitious growth plan for the business to become the UK’s leading skin care provider by volume, overtaking companies such as Nivea and L’Oreal in the process.

See our Portfolio for a more in-depth analysis of these and further Consumer investments.

Duke Street is a long-term investor in the healthcare space, making our first investment in 1997

Since then we have deployed c. €700m in the sector, backing great management teams to deliver transformational business plans.

We believe the sector to be structurally attractive: it is defensive and benefits from significant barriers to entry due to the complexity of the products and services involved.

We also believe that it lends itself well to our investment strategy. Europe is home to a large number of strong management teams, and high value-added businesses which deliver outstanding patient outcomes. Such businesses typically offer multiple routes to value creation. Even the most mature sub-sectors remain fragmented and so there is significant potential for buy and build.

Please see our Portfolio for a more in-depth analysis of our past and present Healthcare investments.

We cover a broad range of Industrials sub-sectors with a particular focus on aerospace & defence, engineering, manufacturing & security

We look to invest in companies with differentiated product or process IP, operating in attractive end-markets, with scope to affect operational transformation through inter alia, a build-up in specific niches, technological changes, or product / geographic diversification.

We back management teams with a clear strategic vision as well as a strong operational focus; and our in-depth understanding of the sector means we are well-placed to work in partnership with such teams.

Our investments in this sector include Deloro Stellite, the specialist engineering group, and filtration solutions provider Madison Filter. See our Portfolio for a more in-depth analysis of these and further investments.

We invest in services businesses with the potential for operational improvement and rapid growth

The services sector encompasses a wide range of sub-sectors, each subject to its own dynamics but often with outsourcing as a key driver. We identify macro trends that will drive above average market growth, and then back businesses providing value added skills and products to their customers in those markets. We are particularly attracted where there is the potential for operational improvement as well as organic growth. We partner with best-in-class management teams providing support, capital and expertise where this is required and materially adds value.

We have considerable experience in the sector, complemented by a large network of industry contacts. Investments we have made in this sector include Ardent Hire Solutions, a heavy equipment hire business, Payzone, a consumer payments business, and the specialist pensions group Xafinity. See our Portfolio for a more in-depth analysis of these and further Services investments.

Our Portfolio


SECTOR: Services

The motor industry’s leading provider of valuation and technical information

An iconic name in the automotive industry, Glass’s Guide nevertheless was a business that needed the right backing to go in a new direction. Duke Street invested in the company just as it was developing a new software-based product for carrying out electronic insurance assessments of cars damaged in accidents. Here was a deal with a clear Buy and Build strategy, that we transformed from a loss making company into a profitable business.

Supporting companies in transition

When Duke Street acquired Glass’s Guide – one of the auto industry’s most important sources of pricing and technical information in September 1995, it was a company in transition and eager to grow.

Relying largely on printed media to serve its customers, the company was just beginning to develop a new software-based product, offering a collision repair estimating system, called Glassmatix. It was an electronic form of loss adjusting which would come to replace the need for costly visual inspections.

Backing the management

We backed the incumbent management team, led by the former Managing Director of the Financial Times Information Services’ online division, Robin Oliphant.

The deal appealed to us because here was a management team with a clear Buy and Build strategy and because this was a company that could clearly realise greater value by using new technologies.

Speed was of the essence as we negotiated the initial investment. We came to the sale process late and had to carry out all due diligence and legal documentation in just seven weeks. We achieved this without deviating from the agreed price.

Rapid growth

With our support, Glassmatix grew from a relational database to become the foundation for a whole range of new products covering all aspects of auto management covering the car’s entire life. We also supported the company’s growth strategy, in particular backing subsequent acquisitions of Glass’s Australia and Bodymaster.


We exited the business in August 1998. By that time Glassmatix had established itself as the UK’s leading supplier of collision repair estimating systems.
