British Best Practices:

Wondering if your small business needs a cookie consent banner? Yes, and the full answer would depend on your location and the types of cookies you use.  Under UK's DPA we know that any website that tracks visitors using cookies (which is very common) needs to get user consent before placing those cookies. This usually involves a nice-looking cookie banner (like the one that you will get from Secure Privacy) that will inform your visitors about cookies and give them a choice to accept or decline.
