Your polling card should say where you can vote with a map on it. If you can’t find your polling card then you can go to your local polling station and they can look you up on the register. Your polling station is based upon where you live/are registered to vote and will be open from 0700 to 2200 on Thursday. To find it if you are in Camden then enter your postcode on this website. If you are in Islington click on this map.
If you are worrying that you might not be registered then look at this useful page on the Camden website or if in Islington see this page, which isn’t quite as good. If you can’t find any help then the best route is to go to your local polling station and ask someone at a time when it is less likely to be busy – during the working day or in the morning before work. Evenings are very busy.
