Britain has the highest energy costs in Europe, and overcharging is out of control. Suppliers make it almost impossible for customers to verify their true usage and costs, while OFGEM’s inaction has left households paying the price. Energydor is a free app created by Chris Dorman to help you check your real usage, uncover overcharging, and hold your supplier to account.
From broken smart meters and inflated estimates to confusing tariffs and billing portals — the system is complex by design.
Energydor is an app built for fixed-rate energy plans. If your bills seem too high or don’t add up, Energydor reveals your true usage and what you should really be paying — giving you the clear evidence to challenge overcharging with confidence.
Do you suspect you are being overcharged for energy but don’t know how to prove it?
Before you can cross-reference your energy suppliers bills, you need to input your fixed-rate electricity and gas tariffs.
Energydor has straightforward fields where you enter your existing kWh unit rate, standing charges, and taxes.
Once your tariff details are saved, our system automatically applies them to your meter readings. This ensures that every calculation reflects your actual costs, giving you a clear picture of your energy expenses.
Energydor is currently engineered for fixed tariffs only and does not yet support tracker tariffs or variable rates. This is intentional, as fixed tariffs offer the most stable foundation for accurate, independent verification.
Once a month — ideally the day before your supplier issues a bill — take a manual reading from your electricity and gas meters. Enter those readings into Energydor to verify your actual usage before you’re charged.
Even if you have a smart meter, don’t rely on the app or in-home display. Always read the physical meter itself to avoid delays, glitches, or missing data. This step ensures you're working with real, verifiable numbers — not estimates.
Energydor transforms these manual readings into an independent report, calculating your actual energy costs — not the inflated figures your supplier wants you to accept. If you’re being overcharged, you’ll see it clearly.
By tracking over time, you’ll catch sudden spikes, inefficiencies, and suspicious charges before they cost you money. This is more than data — it’s proof that empowers you to challenge unfair billing.
Don’t rely on estimates or faulty tech. Take control and hold your energy supplier accountable with Energydor.
Energy providers and landlords can argue over numbers, but they can’t argue with a photo.
We recommend when you log a meter read to use Energydor’s Photo Meter Logging feature. It lets you snap and store timestamped images alongside each meter reading, creating a verifiable record of your energy usage. This ensures every reading is backed by proof, protecting you from billing disputes.
Whether it’s a faulty smart meter, an overcharge, or a landlord dispute, you’ll have concrete evidence stored safely in the app.
Energy companies can dispute numbers. Landlords can question readings. But a photo with a timestamp? That’s bulletproof. Energydor gives you the power to document, verify, and defend your energy usage with confidence.
