Yep, just to their website and type the address. Be careful if it's a leasehold cos you might end up grabbing the wrong information if you're after he freeholder.
If it's a plot of land you can do it via coordinates but sometimes this might not give you any response if it's a small strip with ownership issues. You'll get you money back if they can't find anything.
I think it might even be less that 7 quid.
