The answer to both of the questions in the thread title is "yes", but with some limitations.
For best results and value get the US Deluxe Edition. Do not get the Starter Edition as it doesn’t support multiple currencies. The extra facilities in the more expensive Editions are of no value to a manual user.
To purchase a Quicken membership from the UK you’ll need to give a valid US address if buying direct from Quicken. You may be able to find a retailer who will sell and ship a retail copy for less that the cost of buying it directly from Quicken. Check Amazon.com, Staples, Best Buy etc.
When you create a new Quicken file you have to create an initial account, which for a new installation will be in USD. After you have created that account, go to Preferences and turn on multi currency support, then set the home currency to GBP. All future accounts that you create will then default to GBP. Once you have created your first GBP account you can delete the initial USD account if you don’t need it.
As NotACPA points out, you will have to manually enter all transactions as downloading from UK banks is no longer supported by Quicken (they withdrew from the UK market around 2005).
EDIT: The above is written from the point of view of the Windows version, but I’ve just noticed this is posted in a Mac category. Whilst I’m sure you can purchase and use the Mac version in a Manual mode, I don’t know how it handles multiple currencies. So, if you are planning to use the Mac version, it would be good to get some input from a Mac user on multicurrency support.

Quicken is really only supported in the US and Canada though there is at least 1 UK user that uses Quicken in manual mode. Maybe @Dan Glynhampton will see this and comment.

The Mac version doesn't have the true multi-currency support that the Windows version does, but that may not be relvant in the case of @Tony.r -- if all accounts and transactions are using one currency, it should work. (Quicken Mac's weeknesses with multi-currency support come into play when users are actually using multiple different currencies.)
