These details help estimate how much energy you could generate.
How much electricity do you use?
Find your annual electricity use on your bill or supplier app. It gives us a clearer starting point than a monthly payment.
Electricity only. We deduct the standing charge before estimating your usage.
Electricity rates 26.11p import · 6p export
Check these figures against your tariff. Import is what you pay for electricity; export is what you receive for electricity sent to the grid.
We use your postcode to label the estimate. It does not change the calculation, which uses a fixed generation assumption for Central Scotland.
Meet your new energy setup.
