I recently had my Incapacity Benefit moved over to Employment Support Assistance. So when I went to the dentist he asked if on Benefits and I told him about the transfer produced the evidence that I was on ESA which they had sent me. Signed the form "in good faith" to say I was not giving false information. A couple of months latter received a letter asking me to send proof, which I did. Then probably 6 weeks latter received a letter claiming the charges of £46.00 for check up etc.. and £100.00 Fine for falsely claiming! I phoned them and found out there are two types of ESA one is INCOME BASED (do not pay dental charges or eye check up glasses etc) and there is another ESA which is NOT INCOME BASED ( which is the one I was on) but it does not clearly state on the ESA Benefit letter!
I therefore was advised to pay the whole amount £146.00 ( fine is 5 times the amount of bill so if my dental work was £100 the fine would be £500!) I paid on a credit card and then wrote to NHS Dental and explained the honest error which they appreciated and refunded my fine.
