The Asus-made, seven-inch slate does not have a specific release date, but rather online retailers such as eBuyer have been taking orders and shipping the Nexus 7 to British consumers since last Friday.
Today, the major electronics retailers, such as Currys and PC World, started stocking the tablet, which runs the latest version of Google Android, 4.1 Jelly Bean.
This "soft launch" for the Nexus 7 is a world away from the blitz of media publicity and long queues that accompanied the arrival of Apple's new iPad in March.
Google hopes that the Nexus 7's cheap price and impressive specs can help it become the first Android slate - barring Amazon's seven-inch Kindle Fire - to challenge the iPad.
According to analysts IDC, the iPad accounted for 68% of sales of tablet devices in the first quarter of 2012.
Other data suggests that an incredible 95% of web traffic from tablets comes from iPads, suggesting that the Android slate use is still very low.
Fred Huet, the managing director at telecoms consultancy Greenwich Consulting, said that Android tablets from Samsung and the now Google-owned Motorola Mobility have so far failed to interest UK consumers.
However, Huet feels that the aggressive price point - starting at £160 for the 8GB version - and strong technical specs of the Nexus 7 could change that, particularly with the ongoing absence of the Kindle Fire on these shores.
"The launch of the Google Nexus may have major repercussions for the tablet market," he said.
"Android tablets from the likes of Samsung and Motorola have yet to make any real impact on the market, failing to match the success of Android in the mobile handset space.
"With the delay of the UK Kindle Fire launch, Google has now taken first mover advantage in the smaller form-factor tablet market, something that may prove key to success.
"Based on early reviews it seems that the Nexus has the build quality and interface to compete, something that is supported by its highly attractive price point."
But Huet noted that to challenge Apple's iPad, Google must "build out its content offerings".
The fact, however, that the tablet had to launch without music, magazines or television shows is not a good start for the product.
"Launching without a music service or fully built-out film / TV offering isn't ideal, and while it may enjoy a grace period post-launch, Google would be wise to rectify this situation ahead of the launch of the Kindle Fire, a device that is expected to offer access to a breadth of content," said Huet.
"On the other hand, it is of course entirely possible for users to download their Amazon content onto the Nexus 7, in turn creating a form of 'Super Kindle' that could further squeeze Amazon Fire's market position when launched in the UK."
Rumours continue to rumble on that Apple is also preparing to enter the small-screen tablet space with its own device, with the so-called iPad Mini expected to launch later in the year.
