Innogy Identifying and communicating a clear proposition through a standout sales document


Before it was acquired and became Compleo Charging Solutions UK Ltd, innogy eMobility Limited was a pioneering renewable energy and technology company with a firm international presence in the field of EV charger design and installation.

Looking to build on its immense success across continental Europe by penetrating the UK EV market, innogy approached GroupWhistle with the brief of creating a stand-out sales promotion document to accompany the launch of its UK offering.


We drew on our extensive copywriting and design expertise to create first-class sales materials which effectively positioned innogy within the UK EV market and introduced its innovative hardware and software products to a new audience.

We showcased innogy’s specialist experience in creating robust, tailored EV charging network solutions for businesses in an engaging and eye-catching way to create awareness and stimulate sales.

We formulated a compelling slide deck specifically targeted at a UK audience, highlighting how innogy’s success in installing a plethora of state-of-the-art charging points in more than 20 countries worldwide would seamlessly support the company’s entrance into, and growth in, the UK eMobility market.

“Whistle's ability to untangle a complicated eMobility subject and present it in well-structured, tightly-written and attractively-designed documents is a real skill and their input has definitely boosted our sales process. It's also great that we can call on their skills to support our social media output and to write succinct and engaging news releases when required. The Whistle guys are a fantastic external resource that we know we can trust to deliver projects quickly and to a very high standard.”
