If you've seen headlines about the energy price cap jumping again this winter, you're not imagining it — but you also haven't missed an announcement. There isn't one yet. The cap that will apply from January to March 2027 is still a forecast, built by City analysts and energy consultancies from current wholesale gas and electricity prices, and it will keep shifting until Ofgem locks it in.
This guide sets out what that forecast currently says, what's actually confirmed today, what a typical Milton Keynes or Buckinghamshire household might end up paying if the prediction holds, and what you can realistically do before winter — including home battery storage, with or without solar.
Forecast, not fact. Every number in this article that relates to the January–March 2027 price cap is a prediction, not a confirmed Ofgem figure. Forecasts have moved before and can move again — up or down — before Ofgem's official announcement, expected around 25 November 2026. We've sourced the current numbers from MoneySavingExpert's energy price cap prediction tracker, which aggregates supplier and analyst forecasts — this is their forecast (and the wider market's), not a prediction of our own.
What the January 2027 energy price cap forecast says right now
Ofgem sets the energy price cap every three months, based on average wholesale gas and electricity costs over a defined assessment period. The cap for October–December 2026 is already confirmed. The cap for January–March 2027 is not — it's forecast from current market data, and that forecast is what's making headlines right now.
According to MoneySavingExpert's energy price cap prediction page, which tracks forecasts from several analysts and energy consultancies and updates them weekly, the current prediction is a rise of around 24.9% for January 2027 compared with the confirmed October–December 2026 cap.
That 24.9% figure, and the £2,152/year estimate that comes from it, are MoneySavingExpert's and the broader market's current forecast — not a Depth of Light prediction, and not an Ofgem number. Forecasts like this are rebuilt every week as wholesale prices move, and they have swung noticeably in past years between now and the actual announcement.

What's confirmed today vs what's still a prediction
It's worth being precise about which of these numbers you can rely on today, and which you can't yet:
| Oct–Dec 2026 cap | Jan–Mar 2027 cap | |
|---|---|---|
| Status | Confirmed by Ofgem | Forecast only — not yet set |
| Typical dual-fuel Direct Debit bill (typical usage) | ~£1,723/year | ~£2,152/year (if forecast holds) |
| Difference vs current confirmed cap | — | ~£429/year more (~£36/month), if forecast holds |
| Source | Ofgem | Analyst & supplier forecasts, via MoneySavingExpert |
The confirmed October–December 2026 cap sets a typical dual-fuel Direct Debit household bill at around £1,723/year for typical usage. If the current January–March 2027 forecast holds, that would rise to roughly £2,152/year — an increase of about £429/year, or around £36/month. We're repeating "if the forecast holds" deliberately: this is a prediction built on today's wholesale prices, and Ofgem's actual announcement, expected around 25 November 2026, could land higher, lower, or close to this depending on how the market moves between now and then.

The £2,152/year figure is an average for a typical dual-fuel Direct Debit household with typical consumption — it's not a personal quote, and your own bill will depend on your actual usage, meter type, payment method, and whether you're on a standard variable tariff or something else. Larger households, homes with electric heating, or anyone on prepayment will see different numbers, higher or lower.
What we can say with more confidence is the shape of the change: if the forecast holds, most typical households on a standard dual-fuel Direct Debit tariff would be looking at somewhere in the region of an extra £30–£40 a month from January, on top of what they're already paying under the confirmed Oct–Dec 2026 cap. That's a meaningful jump for most Milton Keynes and Buckinghamshire households, which is exactly why it's worth planning for now, before the cap is confirmed — rather than reacting to it in December.
Why energy bills keep rising
Energy bills rising isn't a one-off event tied to a single cause. UK household bills are shaped mainly by wholesale gas prices (which move with global supply and demand), network and infrastructure costs, and policy costs added on top — most of which sit well outside any individual homeowner's control. When wholesale prices move, the price cap forecast moves with them, which is exactly why the January 2027 prediction has already shifted more than once since forecasters started tracking it, and may shift again before Ofgem's announcement.
The practical upshot for homeowners: you can't influence the wholesale market, but you can influence how much of your own usage is exposed to whatever the cap eventually turns out to be. That's the whole logic behind the next two sections.
Home battery storage — with or without solar
This is the option we'd point most homeowners to first if they're concerned about where the January cap might land. Home battery storage doesn't need solar panels to make sense on its own.
A standalone battery — sometimes called battery storage without solar — can be charged from the grid overnight on a cheaper off-peak tariff, then used later in the day or evening when standard rates are highest. It's a way of shifting some of your usage away from the most expensive hours, rather than paying peak rate for everything, regardless of what the eventual cap turns out to be.
Worth knowing: we won't quote you a guaranteed saving figure for this, because it genuinely depends on your tariff, your usage pattern, and the battery size that's right for your home. What we can do is look at your actual bills during a free survey and give you an honest view of whether battery storage without solar makes sense for you — or whether it doesn't.
Battery storage also works alongside cheap-rate and time-of-use tariffs, which are designed around exactly this kind of overnight-charge, daytime-use pattern. If you already have one of these tariffs, or you're thinking about switching to one, a battery is usually what makes it worth having.
Solar + battery storage: the combined option
If you're starting from scratch, or you already have solar panels and are thinking about adding storage, solar battery storage is the combined option. Solar panels generate electricity during the day; a battery stores what you don't use immediately so you can draw on it in the evening, instead of buying it back from the grid at whatever rate applies once the January cap is confirmed.
The less of your electricity you need to buy from the grid, the less exposed you are to the cap rising — whether it lands at the current 24.9% forecast, higher, or lower. We install solar panels, standalone batteries, and combined solar and battery packages across Milton Keynes, Buckinghamshire, Bedfordshire and Northamptonshire, and we'll always tell you plainly if a system isn't the right fit for your roof or your usage — not just quote you one because you asked.
A free, no-obligation survey
If you'd rather talk it through than read another table of numbers: we offer a free, no-obligation survey for battery storage, solar, or solar-and-battery together. We'll look at your actual usage and roof (where relevant), talk through whether a standalone battery, solar and battery, or neither is the right call for your home, and give you a fixed price — no pressure, no guaranteed savings claims, and no follow-up sales calls if it's not for you.

Frequently asked questions
What is the UK energy price cap?
The energy price cap is set by Ofgem every three months and limits what suppliers can charge per unit of gas and electricity on a standard variable tariff, plus the daily standing charge. It does not cap your total bill — if you use more energy, you pay more — it caps the unit rates.
What is the energy price cap forecast for January 2027?
As of September 2026, analysts tracked by MoneySavingExpert are forecasting the January–March 2027 price cap to rise by around 24.9%. If that forecast holds, a typical dual-fuel Direct Debit household would go from the confirmed October–December 2026 cap of around £1,723/year to around £2,152/year — about £429/year, or roughly £36/month, more. This is a forecast, not a confirmed Ofgem figure, and it can move before the official announcement.
When will the real January 2027 energy price cap be confirmed?
Ofgem is expected to announce the confirmed January–March 2027 price cap around 25 November 2026. Until that announcement, every figure quoted for the January cap — including the ones on this page — is a prediction based on current wholesale energy market movements, not a locked-in number.
Why are energy bills rising again?
UK energy bills are driven largely by wholesale gas prices, network costs and policy costs added to bills, most of which sit outside any individual household's control. Forecasters revise their price cap predictions as these costs move, which is why the forecast for January 2027 has already changed more than once and may change again before Ofgem's announcement.
Can I get home battery storage without solar panels?
Yes. A standalone battery can be installed without solar and charged from the grid on a cheaper overnight tariff, then used later when standard rates are highest. It does not guarantee a specific saving — that depends on your tariff, usage and battery size — but it is one way to shift some of your usage away from the most expensive part of the price cap.
Does solar and battery storage guarantee lower bills?
No. Solar battery storage can reduce how much electricity you buy from the grid, which matters more if the price cap rises as forecast, but we do not promise a guaranteed saving figure — it depends on your roof, usage, tariff and where the cap actually lands. A free, no-obligation survey is the only reliable way to see what is realistic for your home.
Whatever Ofgem confirms in November
The honest position is that nobody — not MoneySavingExpert, not the analysts, and not us — knows the real January 2027 cap yet. What we do know is that energy bills rising is a pattern MK and Bucks homeowners have lived through before, and that reducing how much of your usage is exposed to the grid is one of the few things you can act on now, ahead of the confirmed figure.
