London's FTSE 100 was flat at 9,688.04 in quiet afternoon trade on Thursday.
British Gas owner Centrica was the standout gainer on the index, closely followed by miner Glencore and housebuilder Persimmon.
Banks were also on the rise, having escaped further taxes in Wednesday's Budget, with NatWest, Lloyds and Barclays all up.
Wealth manager St James's Place was in the black again, having surged on Wednesday after Chancellor Rachel Reeves confirmed a stamp duty holiday for newly-listed London shares and ISA reforms to encourage investment in UK equities, and announced plans for new investing hubs.
Imperial Brands, 3i Group and LondonMetric all fell as they traded without entitlement to the dividend.
