In April 2014, United announced that they had agreed a deal with German sportswear company Adidas to produce the team kit for the 2014–15 season and beyond, ending the club's previous association with Macron. This was followed in June with DBL Logistics being unveiled as the club's secondary shirt sponsor until 2016, and in July by the announcement of luxury car dealers, John Holland Sales as the club's main shirt sponsor. In September United released a third kit, featuring a yellow and black shirt, sponsored by Topspring. On 17 October, Sheffield United announced a two-year deal with local business Blue Portal Telecoms with their logo appearing on the shorts of the first team.

On 16 May 2014, Sheffield United released their retained list; Darryl Westlake, Matt Hill, Shaun Miller, Sean McGinty, Elliott Whitehouse, Jasper Johns, Jordan Hodder and Jahmal Smith were all released. Chris Porter was also on the released list, however Nigel Clough confirmed that the club was still in negotiation with him over a new contract. The retained list also confirmed that Mark Howard, Bob Harris and Terry Kennedy had all had their contracts extended. Three days later United signed Jamal Campbell-Ryce on a two-year deal after his release from Notts County, and paid an undisclosed fee to Livingston for Marc McNulty who signed a three-year deal. On 5 June, United announced another double signing with Chris Basham joining on a three-year deal from Blackpool and South Yorkshire born Andy Butler joining on a two-year deal from Walsall. The subsequent week both Ben Davies and Chris Porter signed one-year deals, followed another week later by Tranmere Rovers midfielder James Wallace. As manager Nigel Clough continued to reshape his squad there was continued speculation around the future of defender Harry Maguire with reported interest from Hull City and Wolverhampton Wanderers, with offers of around £1.5m being rejected by United. On 25 June, Febian Brandy was released half way through his two-year contract, exactly a year to the day from him joining the club. The following week, striker Lyle Taylor was sold to Scunthorpe United for an undisclosed fee after only a year at Bramall Lane. Meanwhile, off the field, co-owner Prince Abdullah was appointed to a government role in his home nation of Saudi Arabia and as such stepped down from his position on the board, installing his advisor Jim Phipps as his replacement in the role of co-chairman.
