The actual breakdown of ownership by sector in 2012 highlights the state of play in British Industry.
This April 2017 report from www.parliament.uk on the impact of financial services sector in the UK states.
In 2016, financial and insurance services contributed £124.2 billion in gross value added (GVA) to the UK economy, 7.2% of the UK’s total GVA. London accounted for 51% of the total financial and insurance sector GVA in the UK in 2015. There are over one million jobs in the financial and insurance sector (3.1% of all UK jobs). The UK had a surplus of over £60 billion on trade in the financial and insurance sectors in 2016. In 2015-16, the banking sector alone contributed £24.4 billion to UK tax receipts in corporation tax, income tax, national insurance and through the bank levy.
Not surprisingly, the Services Industry has become a target for Foreign Investors.
