The trade body is a signatory to the Construction Supply Chain Payment Charter which set a 30 day payment target.
But latest Build UK payment data shows only four client members of the organisation have hit the target.
British Land, Landsec, Heathrow and Berkeley Homes have average invoice payment times of between 14 and 24 days.
Great Portland Estates took an average of 46 days.
The fastest paying specialist contractor was Carey Group at 36 days with the slowest Brown & Mason at 103.
Build UK revealed the payment practices of its major contractor members earlier this year.
Build UK said publishing the data will “help the construction supply chain to make more informed decisions and drive good practice.”
