Nadhim Zahawi, a founder of the market research firm YouGov, said he was "mortified" to discover the error, which came to light after he was among politicians criticised over subsidised energy bills.
The Stratford-on-Avon MP claimed the most, with a bill totalling £5,822.27 to cover electricity and heating oil for his estate in Warwickshire.
In a statement posted on his website, he said: "Since last week's coverage of my energy bills I have been looking into them further and can confirm that all claims for heating fuel relate purely to my second home.
"However I have made a mistake with my electricity claims".
WELL THATS OK THEN WE ALL FORGIVE YOU..............
