Business investment up 20% since the UK finally left the EU (until Rachel)

Yet another Brexit myth debunked in full, using the official facts and figures

Montage © Facts4EU.Org 2025

Over 10 years business investment is up by 14%

In the same way the Chancellor misled the public over the fact she did not in fact have to increase taxes in the Budget, today we reveal that she also misled everyone about the state of UK business investment. Once again, this is a good news story for the independent United Kingdom.

Facts4EU spent the past month illustrating how Ms Reeves had been repeatedly misleading the public and the World over the effect of Brexit on the economy. In report after report we debunked her claims using the official facts from the Office for National Statistics.

Today we provide the incontrovertible evidence that UK business investment has grown significantly in real terms, after excluding the effects of inflation. This all happened until this year under Rachel Reeves, as we reported last week.

The increase in UK business investment
since leaving the EU Single Market and Customs Union

UK business investment is up nearly 20% since the UK finally left the EU

Last 12 months in the Single Market and Customs Union (Jan-Dec 2020): £254.41 billion
Last 12 months (Oct 2024 – Sep 2025): £304.13 billion
Increase compared to last 12 months in EU: 19.5%

Business investment in the UK is up – significantly – since Brexit

In the last 12 months, business investment in the UK has exceeded £300 billion for the first time. This is a significant milestone and one which it might have been thought the Chancellor would want to mention.

Since the UK finally exited the EU’s ‘Transition Period’ on 31 December 2020, business investment has risen substantially.

The chart above takes figures directly from the Office for National Statistics. These are the latest figures showing the position up to Q3 of this year, i.e. Jul-Sep 2025. Note: These figures are expressed ‘in real terms’ after excluding the effects of inflation and they are also seasonally adjusted. In other words, we are comparing ‘like-for-like’.

The chart shows that UK business investment is up by 19.5% since the UK finally left the EU at the end of the ‘Transition Period’ on 31 December 2020.

Don't leave this to someone else. You are that 'someone else'.

The Rt Hon David Jones, former Brexit Minister, commenting exclusively to Brexit Facts4EU

“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.”

The longer-term picture, since the British people voted to leave the EU

We have also looked back further, to June 2016 when the largest democratic vote in British history took place. We are including this as as it covers a period of almost 10 years, which mitigates the effects of the Covid-19 lockdowns on the economy.

Looking back to UK business investment since the EU Referendum
12 months pre-Referendum compared to the last 12 months

The 12 months leading up to the EU Referendum (Jul 2015 – Jun 2016): £266.50 billion
The last 12 months (Oct 2024 – Sep 2025): £304.13 billion
Increase: 14.1%

Finally, the timeline - the EU referendum to the third quarter of 2025, by quarter

As with the first two charts, this shows the growth of UK business investment in real terms, excluding inflation. We have included this as it clearly shows that UK business investment did not 'fall off a cliff' after the Referendum, and it is now much higher since we actually left the EU.

This contrasts very clearly with the Government's new agenda to attempt to 'rubbish' Brexit at every opportunity. Once again the facts (from the Office for National Statistics) do not lie. The only question is how much better the UK would have done had Brexit been implemented in full, instead of half-heartedly and after years of delays and uncertainty.

Observations

We have many contacts in the EU and around the World. It is disappointing to us to hear how much the Government's (and some of the mainstream media's) attempts to portray the UK economy as having suffered deplorably because of Brexit have succeeded, despite the fact they are wrong.

Talking down the United Kingdom in this way is deeply unhelpful and should be called out. We would like to hear more pro-Brexit politicians do this.

3. Sparky, "Essentially the above means businesses are more willing to invest following closer ties with the EU"

That's strange as they do not seem to want to invest in the EU !
According to an independent consultancy analysis investment in the EU declined by 24% between 2023 and 2024. This has since been confirmed by the EU competitiveness report. Volkswagen has just announced plans to reduce production in the EU and relocate it to other parts of the world with a loss of 35,000 EU jobs.
.
Relative to the size of the economy the UK is the most internationally invested nation in the world (of any major economy) and the direction of investments are very balanced despite the fact that UK Government debt has increased hugely during this period. This is one of the reasons Brexit is so important. The level of international investment both in and out of the UK has grown significantly since both the referendum and Brexit. This contradicts any claims about "currency movements" and "Government support" is a joke since Labour were elected.
