Case Study: OVO Energy achieves 7–9% customer growth with Voucherify

How Ovo Energy launched a referral program in one development sprint

OVO Energy Spain, part of the OVO Group, is a renewable energy retailer that entered the Spanish market in 2020. As a new brand in a competitive, price-sensitive market, it faced low awareness, limited development resources, and the need to make switching providers feel quick and simple. To solve this, OVO Energy needed a flexible way to launch a referral program without burdening its developers, and chose Voucherify promotion management software.

With Voucherify, OVO Energy integrated a double-sided referral program in one development sprint, with the marketing team managing the rules through the dashboard. The program rewarded both referrers and referees with €20 gift cards, later allowing temporary reward increases to €40 without developer support. The referral initiative drove a 10%+ lift in new users, doubled the original 3% growth target with an average 7–9% increase, and helped OVO Energy acquire more than 14,000 high-value customers through refer-a-friend campaigns.
