Fuel duties earn Treasury £4.4m a day Calculations by the Telegraph show British drivers have paid an extra £350m in fuel duties since Russia invaded Ukraine in late February. The Treasury is raking in an extra £4.4m a day as the cost of filling a typical family car with petrol passed £100 for the first time. The Treasury charges VAT at 20% on road fuels and the RAC says the Government is now taking about 30p in VAT for every litre of road fuel sold on top of the 53p a litre fuel duty rate – so £45 out of every £100 fill-up is tax. The RAC and AA have urged the Chancellor to cut VAT on fuel or to reduce fuel duty further.
