The green energy developer company signed on for a fourth season after agreeing a one-year deal valued at £180,000 - the largest individual sponsorship in Welsh rugby.

Existing secondary sponsors Persimmon Homes, Worthingtons, John West Foods, Cuddy Group, Trade Centre Wales, Trade Depot, Solo Cleaning and Taylors Regional Foods have also agreed to extend their relationship with the Ospreys, while they have secured new sponsorship deals with Fujitsu, 4U Recruitment and Land Rover.

Ospreys managing director Roger Blyth said: “It gives us an enormous sense of satisfaction to be able to confirm such a lucrative and impressive sponsorship package for the new season.

“What is particularly pleasing for us is the mix of national and local companies who will work in partnership with us over the next 12 months.”

As with previous seasons, Ospreys’ home shirt is mainly black with white trim, while the away jersey sees the colouring reversed.
