Pop in a few numbers

Grab your latest bill and copy across the few numbers below — we’ll do the rest. There’s a little note under each one telling you where to find it.

🔒We read your bill, show you what we found, and it’s goneWe never store your bill or your numbers — nothing is kept.
📈 Which bill is this?
Who you buy your energy from — optional.
⚡ Your electricity rates
What you pay for one unit of electricity — a “unit” is also called a “kWh”. Look for “unit rate” or “p per kWh” on your bill.
p / kWh
A fixed daily fee just to be connected. Look for “standing charge” or “p per day”.
p / day
Only if your bill shows it — often near “estimated annual”. Leave blank if you’re not sure.
kWh / yr
🔥 Your gas rates — only if you have gas
The price of each unit of gas — “p per kWh” on the gas part of your bill.
p / kWh
The fixed daily fee for gas.
p / day
Only if your bill shows it. Leave blank if you’re not sure.
kWh / yr
💳 A couple more — optional
Your monthly direct debit. This lets us check it’s the right size for what you use.
£ / mo
So we compare against the price cap for your exact area. Leave blank for the UK average.
