March 2019

All policies announced since Budget 2018 were presented to the Office for Budget Responsibility at Spring Statement 2019. They were scrutinised, certified as reasonable, central estimates and were included in our forecasts. In our March 2019 Economic and fiscal outlook we have published an assessment on the level of uncertainty associated with each of the certified costings. For those identified as being particularly uncertain, we provided greater detail on the most important sources of uncertainty.

Read more in Annex A of the Economic and fiscal outlook. No costings document was published by HM Treasury at this event.
