Analysis by Facts4EU shared exclusively with GB News suggested financing exceeding £300billion for the first time over the past year

Business investments in the UK economy have soared by 20 per cent since 2020 in another post-Brexit success story for Britain.

This success has only continued to rise, with financing exceeding £300billion for the first time over the past year, according to exclusive analysis by Facts4EU for GB News.


The figures come in contrast to the outlook of Chancellor Rachel Reeves, who pointed to Britain’s exit from the EU as the source of the nation’s financial woes.

The findings seem to disprove the Chancellor's warnings about Brexit.

The report by Brexit Facts4EU and The Campaign for an Independent Britain (CIBUK) demonstrates how breaking with Brussels has boosted the UK’s finances.

In the last 12 months in the Single Market and Customs Union, Britain attracted £254.4111billion in investment.

Over the same time period, since October 2024, £304.13billion worth of financing flowed into the economy.

This represented a stunning 19.5 per cent increase over our last months before the UK finally ended the EU’s ‘Transition Period’ on December 31 2020.

In addition to this, UK business investment in the 12 months leading up to the EU Referendum in 2016, compared to the most recent 12 months, increased by just over 14 per cent.

Across the 12 months leading up to the EU Referendum (Jul 2015 – Jun 2016), this figure stood at £266.50billion.

In the last 12 months (Oct 2024 – Sep 2025), this figure stood at £304.13billion, marking an increase of 14.1 per cent.

Former Brexit Minister and Reform UK supporter David Jones said: "The latest Facts4EU analysis provides a valuable reminder that the picture on UK business investment is far more resilient than many critics have claimed.

"It is clear that investment has not collapsed; on the contrary, the most recent ONS figures show that it has been running at levels comparable to, and in some respects higher than, the immediate pre-Brexit period.

"This does not mean every sector is performing equally well, and it does not mean that wider global factors such as the pandemic, supply chain disruption and inflation can be ignored.

"However, it does confirm something important, which is that the UK remains an attractive place to invest and that the country’s underlying economic strengths are intact."

A timeline shows UK business investment in real terms, excluding inflation, increased after the referendum.

The chard dispels myths UK investment would "fall off a cliff" after the Referendum, and it is now much higher since we actually left the EU.

Just this week, Sir Keir Starmer said leaving the European Union had "significantly hurt our economy," warning "frictions" with the bloc must be reduced to enable "economic renewal" in the UK.

He said: "For economic renewal, we have to keep reducing frictions. We have to keep moving towards a closer relationship with the EU, and we have to be grown-up about that, to accept that that will require trade-offs."
