The cost of Brexit · UK-wide
Brexit's estimated hit to UK economic output (GVA) in 2023
−£188.8bn
−7.7% of output
That's about £2,835 for every person in the UK, compared with an estimate of where the economy would have been without Brexit.

Brexit has cost the Richmond upon Thames council area an estimated £385m a year since 2016.
How is this worked out?
Gross value added (GVA) is the value of the goods and services produced in an area.
Researchers at the Brexit Cost Project compared each council area's actual output with an estimate of what it would have been without Brexit. They built that estimate from a weighted mix of economies elsewhere, in Europe, the US and other advanced economies, whose output tracked the area's closely before the 2016 referendum.
The difference between the two is the estimated effect of Brexit. It's a modelled estimate, not a measured loss, and the researchers say it should be read as evidence of how places diverged after 2016 rather than as precise accounting.
The figure shown is the average gap for each year from 2016 to 2023, the latest year of official local output data. It's in real terms, at 2019 prices, and is the headline estimate on this council area's page at brexitcost.org. The council area may be larger or smaller than the constituency.

The EU is our nearest and most important market. The member countries are our neighbours, partners and allies. There have been no benefits to me, my friends, family, borough or country. The disadvantages to me (unable to easily send gifts to friends in EU, queues at immigration when visiting EU, loss of excellent staff from care sector who supported my Mum) are small compared to businesses affected by barriers to trade but all of these were totally unnecessary. At a time of increasing instability we need to build stronger relationships with the EU, true sovereignty is being a strong partner.

When talking about rejoining the EU, the arguments for why we should rejoin are usually economic. However, I think culturally we must rejoin as we have far more in common with Europe than with say, the US. We in Britain must retake our rightful place amongst it’s sister countries and our closest friends.

Brexit has massively impacted my son who is married to a Polish woman whom he met there in 2019. They married in May 2025, but he does not earn enough to apply for a spousal visa for her to come and live in the UK, and he is not allowed to live and work in Poland until he has residency, a process that takes a minimum of three years (which he could only apply for once they were married). So they have lived apart since their marriage, only able to be together during short occasional visits between Poland and the UK. Prior to Brexit, they could have lived and worked in either country without the need for any kind of visa. Even if he could afford to apply for a spousal visa the UK’s complex and expensive partner visa system is extremely stressful. Add to that the requirement to renew every two and a half years until settled status is achieved makes the stress ongoing. It is not only expensive in itself, but is so complex that you really need to employ an immigration lawyer to avoid making any mistakes on your application, as you can't risk it being rejected.

Which sectors could benefit most from EU membership?
Twickenham has:
people employed in manufacturing, mining and utilities
people employed in retail and wholesale
people employed in accommodation and food services
as its biggest employing industry
Why these jobs matter for our relationship with Europe
These three industries employ people in every constituency, and each depends on how easily goods, services and people move between the UK and Europe.
Manufacturing: Frontier Economics found that 81% of the £43 billion a year growth in exports from EU membership would come from manufacturing.
Retail: Rejoining the EU would remove the customs checks and paperwork that have added red tape and costs for shops and their suppliers since Brexit, making it cheaper and simpler to stock goods from Europe.
Food services: Pubs, restaurants and hotels have struggled to fill vacancies since free movement ended. EU membership would let them recruit seasonal workers from across Europe again and help bring down costs for hospitality businesses across the country.
