Is solar worth it in London?

These figures use London’s latitude and typical sunshine for the generation, then the United Kingdom’s electricity price, export rules and incentives for the money. The sun a roof sees in London is the single biggest driver of the result, which is why we model the city directly rather than a national average.

See the full the United Kingdom picture on our the United Kingdom solar page, or the incentives in our the United Kingdom solar guide.

Estimate only, not a quote. Figures use local climate data and average tariffs; your installer’s quote will be exact.
