A NEW study estimates Brexit has cut UK economic output by around six per-cent, with economists citing weaker growth, uncertainty and new trade barriers since the referendum.
The analysis, based on internal data from the Bank of England, suggests that about half the impact came from post-referendum uncertainty.
It also reported the rest was driven by reduced trade with the EU following the UK’s exit from the single market under Brexit.
Researchers say the effect has built up gradually over the past decade, leaving the UK economy smaller than it would otherwise have been.
In Fermanagh, major employers say they have adjusted to the new trading environment but continue to face higher costs and administrative burdens.
Derrylin-based glass producer Encirc said it had to establish new customs systems after Brexit came into force, describing the transition as a period of rapid change and adjustment.
Managing director Sean Murphy said that while operations have largely stabilised, Brexit has left a lasting legacy.
“It is now closer to business as usual, but the reality is an extra layer of cost and complexity for our business,” he said.
Mannok also said Brexit had added pressure to cross-border trade, alongside wider global instability including Covid-19 and geopolitical tensions.
CEO Dara O’Reilly said bureaucracy and uncertainty around goods moving between Ireland and Britain remain key challenges, even as the company continues to invest.
“Our sense is that Brexit has significantly constrained the UK economy with knock-on impacts for overall consumer confidence and demand,” he said.
