Mr Heathcoat-Amory was one of four Somerset MPs ordered to repay expenses
Wells MP David Heathcoat-Amory has had to pay back almost £30,000 following the House of Commons expenses audit.
The Conservative MP said his repayment was delayed because of an error in the original assessment, but he had now paid the £29,691.93 owed in full.
Mr Heathcoat-Amory, who made the claims for gardening and cleaning, had to repay more than any other Somerset MP.
Members for Weston-super-Mare, Somerton and Frome, Taunton, and Yeovil, were not ordered to repay any money.
Mr Heathcoat-Amory said: "The repayment was delayed by an arithmetical error in the original assessment by Sir Thomas Legg, but was made this week."
The MP, who started making the claims five years ago, did not appeal against the decision.
The House of Commons expense review, headed by Sir Thomas Legg, had ordered Taunton's Liberal Democrat MP Jeremy Browne to pay back the second highest amount in Somerset at £17,894.24, but this was reduced to zero on appeal.
Bath Lib Dem MP Don Foster must repay £4,275.74, Wansdyke's Labour MP Dan Norris £1,730.19, and the Conservative MP for Bridgwater, Ian Liddell-Grainger, £350.
