The Nexus One, which is manufactured by HTC, is powered by a Qualcomm 1GHz Snapdragon processor and features a 3.7in 480x800-pixel AMOLED screen.
The mobile network said Google's 'superphone', which was launched in January this year, will be released on April 30.
The handset is free on a 24-month contract, which costs £35 (US$54) per month and comes with 600 minutes of calls and unlimited text messages.
The mobile phone will also be available on a number of other contracts, which start from £25 per month.
Vodafone said the contracts include 1GB of mobile data as well as an additional 1GB of data for those using the handset's Wi-Fi connection at premium BT Openzone hotspots throughout the UK.
The Google Nexus One will also come with Google Maps Navigation beta pre-installed. The free app, which was launched last week, gives Android-based mobile phones turn-by-turn voice and visual navigation.
The Google Nexus One can pre-ordered from Vodafone's website.
The announcement comes just hours after reports suggested the Nexus One had been delayed in the UK.
