Charities with income over £10,000 pa are required to file their trustees' annual report and accounts within 10 months of the year end. Most send these in by post, they are then scanned and posted in the public area of the Charity Commisison website. One problem with this is that your signatures are then on a website and there are some bad people about who might take advantage of this.

A better thing to do is to file online. You simply need to have your accounts in pdf format. Even though these are not signed, they are acceptable. 

For any CA Plus clients, just ask us and we can send you a pdf version by email once the accounts have been signed off.
