It's more than £20m.
For the mid-case scenario, the figure is £36.3m. If discounted at 5% pa, that gives a net present value of £29.9m and, if discounted at 10% pa, £25.2m (p56 of the Saltfleetby CPR):
Disc Rate, Gross PreTax, AEWB PreTax, AEWB Post-Tax
0% £96.7 £50.5 £36.3
5% £76.6 £40.2 £29.9
10% £62.3 £32.9 £25.2
