How much is Brexit really costing us? The Cost of Brexit

The government must urgently advocate for the UK’s renewed EU membership to revive declining exports, campaigners have urged.

The UK’s trade deficit has widened to £9.66bn in March 2026 up from £5.34bn in February 2026 based on newly released data from Office Of National Statistics (ONS). This marks the largest trade gap since January 2022.

Strengthening the UK-EU relationship can help repair trade with Europe post-Brexit, as Best for Britain has called for in our latest report.

Naomi Smith, Chief Executive of Best for Britain said:

“Thanks to Brexit’s trade barriers, mountains of red tape and higher border charges, businesses up and down the UK face the ongoing headache of a significant slump in EU exports, driving up costs, and harming the UK’s GDP.

“We cannot dip a toe in the EU’s trade pool and expect to come out with any tangible economic benefit or an improved relationship with our European allies: to repair the damage demands a far greater sense of urgency, including advocating for the UK’s renewed EU membership, as the public have made clear they support.”
