Other changes will also be made to the compilation of GFCF and business investment in Blue Book 2015, which will also have an impact on their levels and growth rates. These include: improvements to the estimation of major repairs to dwellings; the reclassification of Network Rail and Transport for London; improvements to the adjustments made to account for survey under-coverage; updated source data for the costs of transfer of non-produced assets; improvements to the estimation of tax credits, a component in the estimation of research and development; and annual updates to source data.

These changes will be described in articles to be published later in 2015.
