How we regulate Network Rail

We hold network rail to account for delivering what it promised – at the amount it agreed to do it for – and we require it to meet its obligation to provide a safe, high-performing, and efficient railway.

We do this by enforcing compliance with its licences and by conducting five-yearly reviews that set its funding and what it must achieve within the relevant control period.
