Well done, you'll love every minute (apart from your IRT)!

The bond is officially £200 per month deducted from your basic gross salary for five years (my maths says £12k). However, CEPs start on a lower scale (Yr1 approx £21k gross + allowances) and it takes until Yr7 to reach the full pay scale. Overall, it works out at approx £60k. Still, you don't have to pay upfront, which is never a bad thing!!
