Namealot made me think of two things. If the keywords in the domain are important, you need to find out who would be searching that - people already in the UK or people looking to come in.
Then also need to consider whether advertisers would be providing the service to those people. What i mean is that if the majority of visitors would be outside the UK and most of the advertisers (eg law firms) would be providing a service to those in the UK, you won't get a very good conversion rate
