England may not be a big country but you really need to narrow your search down a bit. The one thing I can say is that you'll be hard pushed to find somewhere in your price range in or around London or the surrounding areas. That said, there are many other towns and cities in England, but I think the 400 pounds if you want two bedrooms is not gonna be easy to find in many of them. So your choice of area maybe limited and not quite what you want. I know in my home town of Worthing, West sussex, which comparitively, isnt that expensive, you could possibly rent a two bedroom flat for 400 ish, but that wouldnt include council tax and would probably be in the back end of the town
Price tends to reflect the area, so the cheaper places tend to be in the less desirable areas. There are a lot of rental properties in the UK, if you go through an agent, you'll have to undergo a credit check and very few do rentals for under 6 months, mostly they like 9 months or a year. If you go through the local newspapers and rent privately it maybe slightly cheaper and you maybe able to have shorter rental term
