If we have invited you to register to vote it is important that you respond. If you don't, we will send you reminders through the post and someone will visit your home. At the end of this process we may send you a requirement to register; if you fail to do so without providing adequate reason why you have not, you may be fined £80. Not being registered can also impact on applications for mortgages or mobile phones, since credit reference agencies use the register to validate applications.
