The U.K. economy expanded slightly more than previuosly reported in the second quarter of the year, revised data showed on Wednesday.

The data showed positive signs from household finances and ⁠business investment that could ⁠encourage Treasury chief John Healey as he prepares October's budget.

Economic output expanded ​by 0.5% in the ​April-to-June period, the ⁠Office for National Statistics (ONS) said.

The reading was slightly stronger than a preliminary estimate for 0.4% growth in gross domestic product (GDP). Economists polled by Reuters had expected the 0.4% rise to be confirmed.

Britain's economy was the fastest growing among the G-7 large ⁠advanced ⁠economies in the first half of 2026, the ONS data showed.

Real household disposable income per head rose by 1.0% in quarterly terms during the three months to June, the biggest jump since the end of 2024 and following a 0.8% ⁠drop in the first quarter.

The ONS also revised up second-quarter business investment growth to an annual rate ​of 5.2% from an initial estimate of 0.8%.

Separate ​balance-of-payments data showed Britain ran a smaller current account deficit than ⁠economists ‌had expected ‌in the second quarter, at 19.9 billion pounds ($26.4 ⁠billion) versus a consensus ‌of 24.7 billion pounds.

Excluding precious metals trade, the deficit ​closed to 1.4% of economic ⁠output, the smallest such ⁠reading in five years, and helped by ⁠strong growth ​in services exports.
