It's just common sense. The other thing to do is to set up an account with these people (or similar):
https://www.creditexpert.co.uk/. Not for the credit check per se, but for the monthly notifications and alerts. Specifically, they will tell you if any organisation has done a credit check on you in the last month, and if any new accounts have been created in your name. If someone tried to steal your identity, the first things they would be likely to do with it would be to set up a bank account, take out a loan or apply for a credit card, and you would be notified pretty much immediately...
