You will most likely find that the time taken to complete your PPL is dis-proportionate to the cost per hour, so with the lower cost option you are likely to fly on more occasions.... So you could finish your PPL by the start of next year.
Also please ask if E.Midlands allows circuits, or do they go to a different field for the Touch and Go training. For instance... Liverpool is so crowded that some of their aircraft train at Hawarden or Sleap.
