The deal expands upon the agreement signed last May to create what Communisis anticipated would be one of the UK's most comprehensive database services.

The extended partnership gives Communisis access to Equifax's complete range of credit and risk data sets that offer both accurate and up-to-date information taken from nearly 40m UK residents.

This comprises more than 300 different sets of consumer traits that the company expects to greater inform its marketing service offering.

Andy Blundell, chief executive of Communisis, said: "When we announced our initial partnership with Equifax in May last year, we were clear in our view that together we had created the UK's most accurate and comprehensive marketing database solution.  

He said: "Today, I am pleased to say that we have launched a range of data solutions which will allow our customers to benefit from even greater data granularity, accuracy and breadth.

"This helps them to target increasingly sophisticated consumers in a manner that meets a clear need, understands individual consumer circumstances and generates the greatest return possible on targeted consumer marketing campaigns."
