You have to go through the process of receiving money into your account, and phone verification.
If you click the get verified link or whatever it's called, then you have to wait up to 5 days and PayPal will send you two payments and you check them and enter the two values, say they sent you 50p and 7p, you'd enter, 50 and 07 into the boxes, then you're verified bank wise.
Address wise you have to do it by phone. You go to the site and carry on through the verified process. After you have finished the bank one that is. You get a phone call from robot that gives you a code, or you get sent an email with a code, I think it's email, then the call comes, you enter your PIN you get in the email, and then you're verified by address.
You can send and receive payments on any account type, you can use personal if it's personal, or business if it's business. You just get higher limits on the account type, of what you can send and receive. Also business one is used for taxation.
