There are a few rules when someone wants to start their own web site. For obvious reasons there needs to be trading name, address for correspondence and payment details if one is selling a product or otherwise encouraging folk to pay for anything. Apart from these however, there needs to be some legal information such as the formal businss name, in full. There must also be as physical address from where the business operates from, or a registered office address if applicable. The contact information need only be in the form of a valid email, or a contact form through which interested parties, hopefully customers, can register their request for you to make contact. One area that sometimes causes confusion is whether is is legally necessary to show your Website Terms & Conditions, but these are not always needed. However they do help to protect the site by setting ground rules and conditions for its use, to be fair to everybody. The recent laws around data protection, known as UK GDPR have a set of principles, and these are: fairness; transparency; purpose limitation; minimisation; accuracy; accountability; storage & security. These are just for starters!
