en.Wedoany.com Reported - Keady Construction topped the monthly contractor rankings published by UK construction data provider Glenigan in May, driven by a residential project in Stockport.

The project, commissioned by developer Amstone, is a build-to-rent development called No 1 Knightsbridge in the Cheshire town. The scheme includes three buildings, comprising 588 apartments, 34 three-bedroom houses, and two commercial units. These buildings will replace a Sainsbury's shopping centre, with Keady expected to start construction in the first quarter of 2027. This marks the second time Keady, a subsidiary of OHOB (a CN100 company), has entered the monthly top ten since Construction News began publishing the rankings in February 2011.

Willmott Dixon ranked second in May, trailing the leader by £5.7 million. The company secured nine projects worth a total of £144.3 million, with the most significant deal being a £35 million contract to build a new leisure centre in Cranleigh, Surrey. It was selected as the preferred bidder in December last year, with the main contract awarded in May this year.

Morgan Sindall jumped from sixth to third place, completing 20 transactions worth a total of £139.6 million. According to Glenigan, its largest project last month was the construction of a new SEND school in Liverpool, a £37 million brownfield project. Students will relocate from four existing sites to Princes Primary School, which will feature a 5,800-square-metre site offering a school hall and a hydrotherapy pool in addition to classrooms, and is expected to accommodate 250 students by the time it opens in 2029.

Mace ranked fourth with a laboratory expansion project in Norwich. The contractor will handle the first phase of a £250 million laboratory expansion for the John Innes Centre research institute. Mace will begin work on the Norwich site in 2028, providing new main laboratories, offices, training, and collaboration spaces for plant and microbial science research. The main laboratory building will have a floor area of 21,000 square metres, including 12,000 square metres of space. The development received planning permission from South Norfolk District Council earlier this year. This success also marks Mace's return to the monthly top ten for the first time since November.

Bam, ranked fifth, secured a £55 million contract for the second phase of the "Our Cultural Heart" regeneration project in Huddersfield. The contractor signed five deals in May, worth a total of £100.7 million. Glencar took sixth place, with the final phase of Pure DC's £1 billion Brent Cross data centre campus development valued at £100 million, enough to propel the contractor into the top ten. It will be responsible for expanding the site by 23,186 square metres. The entire Brent Cross data centre campus represents an investment of over £1 billion, with the scheme supported by funds managed by Oaktree Capital Management. The latest phase, known as LON01 (B2), follows the completion of the campus's first 20MW building, which became operational in 2024 and is fully leased.
