David Chambers, 33, allegedly turned up on the pensioner’s doorstep offering to vaccinate her against coronavirus in exchange for payment.
Chambers is accused of carrying out the bogus procedure on December 30 last year, and returning on January 4 to try to get a further £100 from the woman.
He has now been charged with two counts of fraud by false representation, assault by beating, and two breaches of Covid-19 restrictions on movement.
Chambers appeared in the dock at Westminster magistrates court this afternoon, indicating he will deny all the charges.
He formally entered not guilty pleas to the two fraud charges and was remanded in custody until a hearing at Kingston crown court next month.
Prosecutor Matt Barrowcliffe said the pensioner lives alone in her Surbiton home.
It is said Chambers “called at the home of a 92-year-old vulnerable lady who resides alone and purported to administer a Covid-19 vaccination”.
He returned on January 4 to the same address, asking for more money, the prosecutor said.
Deputy Chief Magistrate Tan Ikram today remanded Chambers, from Surbiton, in custody until the next hearing on February 12.
