Retailer Phones4U is offering the handset in black or white, and has promised to throw in a Nokia Play 360-degree speaker worth £120 at no extra cost for customers who order the handset today (April 10).
The handset is available for free on a £36 a month contract from O2. Vodafone is offering it at £57 a month with 3,000 minutes thrown in, along with cashback.
Nokia's Lumia 900 launched in the US earlier this year. The flagship Windows handset features a 4.3-inch AMOLED ClearBlack Display, the largest screen offered by Finnish mobile giant Nokia, and is powered by Microsoft's latest mobile operating system.
It is also Nokia's first LTE phone, making use of the cutting-edge 4G technology that enables faster connection speeds for next-generation services.
The handset's primary camera features Carl Zeiss optics, a large aperture of F2.2 and a wide angle focal length (28mm), while the Lumia 900 also has a front-facing camera for video-calling.
Phones4U claims that the handset will be released in the UK on April 27.
