The company initially took on Instinctif, which, according to the PRWeek UK Top 150 is the country's 13th largest agency, as its financial PR and investor relations firm in June.
It has now taken on a corporate comms brief, on an ongoing monthly retainer, after being one of a small number of firms invited to pitch to the company's CEO and other executives.
Instinctif's work will focus on positioning Redrow as a "Great British business" with a commitment to apprenticeships and sustainability, both from an environmental and a social perspective, through media relations, thought leadership, content creation, digital comms and other work.
The company did not previously retain a corporate comms firm, but works with a number of agencies on a regional basis to support development plans at a local level.
Recent entries in the various lobbying and public affairs register show it as having worked with Curtin&Co, PPS Group and Tristan Fitzgerald Associates.
John Wriglesworth, Instinctif's managing partner on the account, said: "Redrow is a fantastic example of a successful and responsible British business, which is not only creating beautiful homes and high-quality lifestyles for its customers but, importantly, sustainable communities for them to live in. This holistic approach sets them apart and we look forward to supporting them with a multi-channel communications programme that delivers against their business objectives."
The company has nearly trebled its revenue from £479m in 2012 to £1.4bn for the year ending 30 June 2016, completing 4,716 builds and employing nearly 2,000 staff in the year.
