Between August and December last year, the "big six" energy companies outlined price rises of between 6% and 10.8%.
At present, the government is forecasting average household energy bills – power and heating combined – will reach about £1,285 in 2020. But even including the £280 added to bills as a result of green policies such as subsidies to renewable energy, this bill level will be 7% lower than the £1,379 estimate without such policies.
What this forecast cannot fully take account of, however, are the potential major rises in gas price. While prices for wind and solar have been steadily decreasing, the future price of gas is up for grabs. For UK consumers, gas could be a bigger leap into the unknown than opting for renewable energy.
If you generate your own electricity your energy supplier might pay you money. This is called a ‘Feed-in Tariff’ (FIT).
