Custom research revenue grew 11% from £54m to £60m, although it was static in constant currency terms.

The company said its strategy was to focus investment on data products and services while aligning custom research with its panel-centric methodology to improve margins. It said it was increasingly selling the in-depth data derived from its digitally interactive panel as a subscription-based service and in custom research through higher margin annual tracker contracts.

Stephan Shakespeare (pictured), chief executive, said: "This is the third consecutive year in which YouGov has delivered growth significantly above the market, both in revenue and profit. We have made further progress in our strategic shift to data products and services sold on subscription and this is bringing increased margin and greater visibility.

"Our systematic approach to market research which combines our syndicated data with new proprietary analytic methodologies to deliver greater granularity and accuracy, points to an exciting future. Trading in the current financial year has started in line with our expectations and we expect continued growth consistent with our ambition to become a leading player in the global data and analytics market."
