You're mixing a third rate extension with a domain that only works for the UK market.
.co works much "better" (relatively speaking) for short, high value concepts applicable to the US, because there may be companies over there willing to buy it as a cheap'n'nasty substitute for the .com. But we're talking 1-2 word mega value niches.
But for the UK market, it just looks like the printer ran out of ink before it got to the ".uk".
For the above reasons, I don't see any particular value in it.
