Hundreds of Met police officers refused exemption from the newly extended Congestion Charge are paying up to £300-a-month to drive their cars to work.
Police are among emergency services being made to pay the higher £15 seven-day central London levy introduced in June by Mayor Sadiq Khan.
A survey of 4,000 rank-and-file officers found 93 per cent believe driving is the safest way to prevent catching and spreading Covid-19 on public transport.
But while NHS and care home staff are entitled to a C-charge refund, other emergency workers only qualify when driving operational vehicles.
Ken Marsh, chairman of the Met Police Federation, said that the fact officers had to pay the C-charge when other key workers did not was “a slap in the face to our brave colleagues”.
“Officers should not be financially penalised for travelling to their shifts to keep the public safe,” he said.
“Since the beginning of this pandemic, police officers in London have worked tirelessly to keep the public safe at no small risk to themselves.
“To be told that they now have to pay the congestion charge when other key workers retain an exemption is a slap in the face to our brave colleagues.”
Some 439 officers said the change cost them between an extra £75 and £150 each month, 253 officers said between £150 to £225 and 185 stated £225 and £300. About 139 said it cost over £300.
A Transport for London spokesman said: “The police are doing a phenomenal job responding to the impact of coronavirus on London.
“All operational emergency service vehicles are exempt from the Congestion Charge. Some services such as the London Fire Brigade have chosen to cover the cost of other vehicles themselves.
“The Government required TfL to bring forward proposals to widen the scope and level of the Congestion Charge as part of the recent funding deal.
“Free travel on public transport is made available to the police in London.”
