Bill Check · free Verdict in 2 minutes
Your supplier broke a rule. We tell you which one, and what it owes you.
Upload the bill you were told to pay. We read the dates, readings and rates against the UK rulebook. The Verdict names the Rule and the pounds you should not be paying.
Free, and honest: if you have no case it says so
Exhibit 01The Verdict
The gap is not letters. It is somebody reading this bill.
Every Verdict states a Rule and a figure in the same sentence. This is what one looks like.

Your supplier is billing you for 31 months of unbilled energy.
Claim Figure
£0
You should not be paying £1,180 of this bill.
Ofgem back-billing rule. You cannot be charged for unbilled energy older than 12 months, so everything before 2025-09-01 falls away.

The Clock
Your supplier has 8 weeks. You can go to the Energy Ombudsman from 2026-10-26.
Exhibit 02The problem
A bill goes wrong and you are instantly outmatched.
Ring the supplier and you get a script and a callback that never comes. Search for help and you find blank template letters that assume you already know your rights.
So most people do the one thing the supplier is counting on. They pay it.

Deemed and out-of-contract rates, business Rulebook
No subscription. Emailed reminders on the dates that matter, because most disputes are lost by missing a deadline.
Exhibit 06Where we stop
The boundaries are the product, as much as the Rulebook is.
We never take a cut
A claims firm takes 25% to 40% of what you win. We take £19 or £49, once, and that is the whole transaction.
We never sell you on
No advert, no insurance lead box, no broker introduction. Nobody buys your panic from us.
We never act for you
We are not lawyers and we do not become a party to your dispute. You send the letter, and you stay in control.
We are not the regulator
