Two MLAs have used up their annual £7,000 constituency office expenses allowance three months before the end of the financial year.
It comes amid rising energy bills during the cost-of-living crisis, which Stormont sources say has placed added pressure on MLA budgets for their constituency offices.
Under Assembly rules, MLAs can recover a maximum of £7,000 a year in "constituency office operating expenses", which includes utilities such as heating and electric.
