for web browsing and word processing, that is ample power. while not a very fast CPU it has a fair amount of RAM and should work fine, if it does seem slow, it it probably due to the bloat ware that will inevitably come with it, and then you simply do a clean windows install.
Being the the UK, the main places I'd check would be either Amazon or Ebuyer. I think he's budget is around £300 but as I rely on more power for 3D programs and rendering, I'm unsure of what a more ideal laptop should be.
If anyone could suggest an ideal laptop within that budget I'd be extremely grateful. I am lost on value when it comes to laptops.
