The January 2026 price cap is rising — solar can help you reduce what you buy from the grid.
If your electricity bill has felt like it changes every time you blink, you’re not imagining it. Ofgem has confirmed the energy price cap will rise by 0.2% for January to March 2026, which is a small increase for the average household.
What is the price cap, really?
The cap applies to the default tariff (often called the Standard Variable Tariff). It’s a limit on the unit rates and standing charges suppliers can bill — it’s not a “maximum total bill” for everyone, because your usage still matters.
So what does it mean in pounds?
Ofgem says an average dual-fuel household paying by Direct Debit would be £1,758 per year on the cap for this period.
Why this matters for solar customers (and future solar customers)
Price caps move. Wholesale costs move. Standing charges move. That’s the point: the grid is still unpredictable. Solar helps because it lets you make (and use) more of your own electricity instead of buying everything at whatever the rate is that quarter.
And if you add a battery, you can push that further by using stored energy in the evening — often when electricity feels most painful.
What you can do next (simple options)
- If you’re on the default tariff, it’s worth checking if a fixed deal suits you (even short-term).
- If you’re thinking about solar, this is exactly why people do it: less exposure to price swings and more control over day-to-day costs.
