British Gas more expensive than French Gas
Strictly it is "Gaz de France", but the most recent round of price increases put the price of British Gas consumption for 20,400 kWh of gas per year at £704 whereas Gaz de France costs £694.
Using the British Gas Standard Tariff of 5.21p per kWh up to 4572 kWh and 2.94 over that. GDF's tariff for this is 4.38 Euros per kWh plus 125.21 standing charge. An exchange rate of 0.68025 Euros per pound
The calculation is:
23820.12+46534.32 pence = 703.54 pounds
The point about this is that France imports about 95% of its gas. We still produce more than half of the gas we use.
There have been problems in the commercial market for some time. These problems have now come through into the domestic market.
