Check your system size
Use the installed capacity on your installation certificate. If it is close to 15 kW, ask British Gas which tariff applies, especially if you have added more panels.
Would switching electricity supplier help?
At 2,000 kWh exported a year, the difference between 3p and 12p is £180. Compare that extra income with any change in the cost of the electricity you buy.

Before you choose
If an offer means changing electricity supplier, compare what you would pay for electricity as well as what you would earn. Include the daily standing charge and any equipment you need to buy.
