My data journalist husband decided to use his professional skills for a side project when we couldn't find a nursery nearby for our daughter and had to get creative, but found it difficult to figure out where they all were. To solve this problem he made a map using data from Ofsted - they're searchable by postcode or name, colour-coded by rating. (Obviously Ofsted ratings have to be taken with a grain of salt and you have to find the place that's right for the child, but it's a reasonable place to start.) Too useful to keep to ourselves, so feel free to use & share. It's www.findagoodnursery.co.uk/. To be clear, this isn't an advert - he's not making any money off it, just trying to help other parents out. Hope it's handy.
