Sustainable and responsible financing - our Chief Financial Officer's review

We made the decision to increase investment in some critical areas during the year to drive longterm improvement. This saw investment levels, at £1.2 billion, break the £1 billion barrier once again, which is three times the annual investment compared to the five years pre-privatisation. Over the last 15 years we’ve invested over £15 billion in the business.
