Small and medium-sized enterprises from more than 50 sectors had to demonstrate positive growth in revenue over the past four years and outperform their sector peers.

Eclipse is one of the UK’s largest commercial print, direct mail and cross-media providers and employs 300 people across five sites from its base in Kettering, Northamptonshire.

London Stock Exchange Group chief executive Xavier Rolet said: “The 1,000 companies have on average more than doubled their revenue in the last four years.”

Eclipse marketing and communications manager Owen Purkis said: “We have grown mainly by acquisitons including 4DM. But even without that we have had huge success in all business areas.

“We have gone from a £24m printer to a £40m group offering print, DM, data and cross-media work. We have spent £2.5m on machinery, most recently a CMC 9000 enclosing machine.”

Financial technology company DueDil blended performance indicators, balance-sheet analysis and credit health checking to identify the 1,000 top performing companies.

Eclipse managing director Simon Moore said: “We’re honoured to have been chosen as one of the 1,000. This is especially so as the list is collated using objective statistics.”

Over the past few months Eclipse has been on a re-branding exercise, creating a new logo and website. It dropped the word 'print' from its name to mark a shift to offering a broader service.

“We’ve always offered a complete campaign management package, but probably weren’t vocal enough about what we could do. 

“A few customers were benefitting from having their print, direct mail and cross-media services under one roof, but we were the industry’s best-kept secret.”

In his foreword to the report chancellor George Osborne said the report was “a remarkable list of outstanding companies”.

He added they were “built by the drive, commitment and vision of Britain’s entrepreneurs and business leaders”.
