Why pay anything when other UK solar calculators are free ?
Most UK solar calculators are free because they make money by selling your details to installers.
BatteryTailor is different.
We charge £7.99 or £24.99 because we work for you, not an installer. No commissions, no lead sales, and no incentive to recommend oversized systems.
Our recommendations are based on the data, even when the answer is:
“Don’t buy one yet.”
