Comparing fuel prices

Does anyone know if there is such a website that lists the cheapest fuel in your local area? I am sure years ago the Yorks Evening Post newspaper used to list the garages with the cheapest fuel (petrol & diesel) in various towns in Yorks. I know diesel is always cheaper in Dewsbury or Keighley, than here in Harrogate. I don’t use that much diesel to go to work, i try to get as many nights out as i can to save on fuel.
