I changed my name, £50 and no real problems. I'm planning to change it again fairly soon, but I can't decide what to change it to...unleashes MR's punsters
 
Not trying to get off-topic here, but I know one couple who were both professionals and neither wanted to change their name when they got married. But when they had a baby, they couldn't agree on whose surname the baby should take. So they "combined" parts of both surnames to come up with a totally new surname. So, as an example, if mom was Smith and dad was Jones, the baby's surname is now "Smones". Seriously. I'm not making this up.
 
Make sure to get everything changed over asap, it'll only cause issue later on.

in scotland it's pretty trivial, you just print out a document, take it to a solicitors sign it, have them sign it and then they'll make you a few copies. you then have to show it to the relevent people and the list is rather long and you'll likely only have 3 or so certified copies so it takes a bloomin age, right now for me the passport office still has one, the student loans company has annother and my university has the third and is pretending they mailed it back to me when they didn't.
