3-4% of electricity bills contain errors

That's over £1.2 billion in recoverable overcharges going unnoticed annually. The problem? Validating bills and forecasting future costs requires tools that only large TPIs can afford.

Until now.

Step 1

Everything starts with your MPAN

Your 21 (or 22) digit Meter Point Administration Number is more than just a number - it's encoded with everything we need to know about your electricity supply.

Your local network area (Distributor ID)
Which pricing tariff applies (LLFC)
Your customer type (Profile Class)
How your meter is set up (MTC)
Step 2

We retrieve the exact rates your supplier uses

Every rate comes from official documents published by the electricity networks - the same documents suppliers are legally required to follow.

Published by the 14 regional electricity networks.

We show our work - every calculation is transparent

No black boxes. Every charge component is calculated using the same method all electricity networks must use and displayed step-by-step so you can verify it yourself.

What we validate - and what we cannot

We validate all industry-standard charges with published methodologies. Some charges require customer-specific information we don't have access to.

*CM Levy is trickier to pin down than other charges - there's no single published rate, so even industry experts estimate it. For half-hourly meters, we're about 95% confident. For standard meters, a bit less - though it often won't appear as a separate item on your bill anyway. Either way, CM only makes up around 3% of your total charges.

Stop Bringing a Spreadsheet to a Software Fight

Large TPIs have validation engines. You have determination and late nights. Time to even things up.
