There probably isn't a house in the land that doesn't have some of these spiders. This is a missing sector orb weaver, most likely Zygiella x-notata. A harmless & very widespread spider, though they are occasionally mistaken for false widows. If you look closely at the head you may see that it is brown at the sides and dark/black in the centre? False widows tend to have more even colouring accross the head. The pattern on the abdomen doesn't fit for a false widow either. Lastly, these spiders weave the classic orb web, that hangs vertically, parallel to the widow pane - false widows tend to weave a messy, shelf-like web and hang in it horizontally, upsde down & belly up.
