How we work
One-off payment, no subscription
Independent — we never sell your details

You pay us, so we work for you.

The popular quoting sites are free because they sell your details to installers who then chase you. We don't. Your one-off payment is the only thing we earn from your visit, which is exactly why our analysis answers to you and no one else.

Pricing questions

Is the free quote check really free?

Yes. Upload one quote and see the full verdict for nothing — no card required. You just create a free account to view your results.

Is this a subscription?

No. Every plan is a one-off payment. Pay once for the tool you need and that is it — there is nothing recurring.

What is the difference between Quote Checker and Full Analysis?

Quote Checker analyses the quotes you already have and compares them side by side. Full Analysis works the other way around — it uses your actual energy data to work out the right battery for your home, even if you have no quotes yet, and it includes everything in Quote Checker.

Do I need solar or a battery already?

No. You can use the quote tools with any quote you have been given, and Full Analysis models your home whether or not you already have solar or a battery.

What do I need for Full Analysis?

A connected energy account. We securely read your smart-meter consumption so the analysis is based on how your home actually uses energy, not an average or an estimate.

Is my data safe? Do you sell it to installers?

Never. Unlike the popular quoting sites, we do not sell your details to installers. You pay once and we work for you — your data is only ever used to give you your own analysis.

Not sure where to start?

If you have a quote, check it for free. If you don't, let your energy data tell you the right battery.
