66% of UK homes sit on their supplier’s standard rate.
The government caps this rate, but a cap is a max, not a good deal. At its widest, £508 a year separates the cheapest supplier from the dearest for exactly the same energy, in the same home.

Saturday is this home’s dearest day
I watch every day against this home’s own normal. When something starts costing more — a heater left on, an immersion firing at 3am — you hear it that week, not on a bill three months later.
Daily pulse
Your average day, half hour by half hour
I check in every morning with what yesterday cost and how it compares. The warm band is when power is dearest — moving one load out of it is free money.
Goals
This home against a typical UK home
Set a target and I hold you to it — month by month, against your own past and against homes like yours. A goal could be monetary, usage, to reduce, to use more to hit a target, or a streak — whatever you want to aim at, I can set it, track it and tell you how you are doing against it.
Your year
A whole year of half hours, in one picture
Totals hide habits. Here a year of your own readings is one image — the evening ridge, the weekend lie-in, the fortnight you were away. You will spot things in it about your own house that no summary would ever have told you.

What it cost, month by month
Nobody itemises a bill for you. I read the shape of your own usage and tell you which slice is which — so “the bill went up” becomes a thing you can point at. Was it colder so the heating ran longer, did the washing move to a dearer hour, or did the cap and the daily charges simply go up again?
Summer vs winter

And what that costs across the year
Usage and bills mostly rise because of the weather, not because anything went wrong. Seeing the size of that swing is how you budget for it instead of being surprised by it — and how you tell a cold month from a real problem.
Carbon & green

Carbon here is measured the same way the money is — your own kWh against the grid’s real intensity in your region, not a national average. So I can tell you which hours are cleanest where you live, and then tell you how much carbon your timing actually saved.
Drawn from a real year of half-hourly readings in a sample home, priced at the rates on the Save side. Connect your meter and every one of these becomes your own house.
