For most of the decade since the 2016 referendum, many economists, political analysts, and industry experts believed that Northern Ireland would be the part of the United Kingdom most damaged by Brexit. But the latest economic output data suggests almost the very opposite, and the gap with the rest of the country is now wide enough that it amounts to more than a statistical anomaly.
Figures published yesterday, 18 June 2026, by the Northern Ireland Statistics and Research Agency show the region outperforming the UK across services, production, and retail in the first quarter of the year. The pattern is broad rather than concentrated in any single sector, which is what makes it harder to dismiss it as mere statistical noise.
The services sector, which accounts for the largest share of local activity, grew by 0.9% over the quarter and by 2.3% over the year. The equivalent UK figures were 0.8% and 1.4%. On a longer view the divergence is starker still: services output in Northern Ireland now stands 11.3% above its pre-pandemic level, against 8.4% for the UK as a whole. Within that, business services and finance rose 4.1% over the quarter, with transport and communications and other services also contributing.
Production told the most striking story. Output rose 2.1% over the quarter and 7.6% over the year, while UK production was effectively flat at 0.2% and 0.1% respectively. Manufacturing, up 9.1% over the year, did much of the work, alongside gains in energy supply and in mining and quarrying. The result leaves Northern Irish production 10.3% above its pre-pandemic level at a time when the UK as a whole remains 7% below it.
Retail, a subset of services, completed the picture. Sales rose 2.1% over the quarter and now sit 3.9% above their pre-pandemic level, in contrast to a Great Britain figure that remains 0.7% below. Over the most recent four quarters, retail output in the region grew 4.4%, more than double the British rate. One caveat applies: NISRA has released the Retail Sales Index as an official statistic in development, so the methodology may yet be revised.
None of this began in the first quarter of 2026. Official regional data show the Northern Irish economy expanded by 16.5% between 2015 and 2023, faster than any other major part of the UK, against roughly 11% for the country overall. NISRA’s own estimates put output growth at about 6% since 2022, more than double the 2.8% recorded for the UK as a whole. The region has also been the only one to record an increase in employee numbers over the past year, even as the wider labour market has softened.
The structural explanation is by now familiar. Under the post-referendum settlement, refined by the Windsor framework, goods produced in Northern Ireland that meet European Union rules can move into the Republic and the wider bloc without the customs checks that have weighed on businesses elsewhere in the UK. That dual access has quietly redrawn the region’s trade map. Research by the Economic and Social Research Institute found that 26% of Northern Irish exports went to the Republic of Ireland in 2023, up from 14.4% in 2015, while the share destined for Britain fell to 51.4% from 59.3% over the same period. NISRA data point in the same direction, with the Republic’s share of the regional economy, excluding financial services, rising to 26% in 2024 from 14% in 2015.
The orthodox caution is warranted, however. Some of the outperformance reflects a catch-up effect from a low base, the legacy of an economy that lagged the rest of the UK for years. A buoyant economy in the Republic has also flattered the figures north of the border. And business representatives have argued for some time that the advantage of dual-market access remains largely untapped, benefiting incumbent firms rather than drawing in significant new investment. Frictions in trade with Great Britain, meanwhile, have not disappeared.
The next test arrives on 25 June 2026, when NISRA publishes the Northern Ireland Composite Economic Index, the closest proxy Stormont has to a measure of GDP. Should it confirm the direction of this week’s output data, the more interesting question will not be whether Northern Ireland is outgrowing the rest of the UK, but how durable a lead built partly on constitutional accident can prove to be.
