LONDON, Oct 28 (Reuters) – British inflation is set ​to average 3.4% in ‌2027, the country’s budget watchdog said on Wednesday following finance minister John Healey’s first budget.

The Office for Budget ‌Responsibility ​expects price growth ⁠to peak at ⁠3.75% in early 2027. Inflation then average 2.1% in 2028 and 2029, before reaching 2% ​in 2030.

British inflation rose more than expected to 3.5% in ⁠September, its highest ⁠since October 2025, data ​showed last week, as the surge ​in energy prices caused by ‌the Iran war gathered steam.

An earlier section of the document showed inflation projections to the ⁠nearest half percent.

The OBR revised up its forecasts from its previous ones which ⁠were ‌prepared before the Iran ⁠war broke out at ​the ‌end of February and ​saw inflation ⁠at 2% in each year between 2027 and 2030.
