As well as BT, the firm has deals in place with Elonext, Intel, Hewlett-Packard and Microsoft. It will use the partnerships to supply BT Broadband, BT Home Monitoring, Windows Media Centre and an HP PC in all new Berkeley Homes, following a trial at its Chelsea Wharf development.
Abrocour chief executive Sam Sethi said it is in talks with "eight out of the ten" top building developers in the country to reach similar deals.
It is also looking to develop tailored packages, including a family deal likely to offer a broadband-enabled Xbox console as part of the house purchase.
More than 300,000 homes are built every year and Abrocour is confident of reaching agreements to fit broadband into 100,000 of these. Sethi said housing developers were keen because "it offered a good point of differentiation for prospective buyers".
