Are your emails up to date?
Companies are now required to include their company registration number, place where the company was registered and the registered office on their website and emails, according to changes to the Companies Act 2006. This has been ‘law’ since January 1st 2007 and companies who do not comply may face a fine.
While this has been required on all business letters, it is now being enforced on websites and emails due to the rise in eCommerce and purely online companies. It is not necessary on all web pages in a site, but is likely to be seen on all emails to avoid having to decide which are or are not classified as ‘business letters’.
