ONS has had a number of widely reported issues gathering information from which itās statistics on the current state of the economy are derived - These are then used by government, private sector and organisations like the Bank of England or the OBR to feed into their forecasts for future expectations. Both the OBR and BoE have commented this year on the challenges they are having with the quality of data provided by ONS.
Itās not unusual for their to be some revisions, but the frequency and scale here appear to be significant.
ONS has seen response rates to its surveys drop from around 50% to as low as 13-17%, with it having to delay publication of some of their reports and give warnings on the quality of data within their surveys. A low response rate means that the actions of one large business could give a misleading indication of what is happening at ground level.
There was a formal review into the ONS earlier this year.

For several years the OBR have been criticised by commentators that their modelling was too generous towards future growth expectations. This year they have attempted to tighten up their expectations which has led them to cutting their growth expectations for the next 5 years. Most likely coincidental it happened under a Labour government, but probably left a bad taste in the chancellorās mouth all the same.
However, given the above concerns with ONS data and the questionable assumptions I referred to in the previous post, the reduction in growth expectations may be flawed.
No, the level of growth the UK economy the OBR expects the economy to grow by across the next 5 years. (so they forecast the economy will be 3.5% bigger in 5 years than it is now rather than 3.75% bigger. That perceived reduction in growth means the government will have less revenue than previously forecast and has to either identify additional sources of revenue or cuts to spending to compensate if it wishes to meet itās targets).
In the first quarter of this year I think it was forecasting for just this year alone growth of around 0.5%, yet by the recent budget this had risen to about 1.5%.
