Today’s announcement from Ofgem confirms that the energy price cap will rise significantly from 1 July 2026, marking a sharp shift after the brief respite households saw earlier this spring. For millions of UK homes on standard variable tariffs, the change will feed directly into higher bills through the summer—and potentially beyond.
Here’s what’s changed, why it’s happening, and what it could mean for family finances.
A 13% rise – but what does that really mean?
The headline figure is a 13% increase in the price cap, taking the annual cost of energy for a “typical” household from £1,641 to around £1,862.
That’s an increase of roughly £221 per year, or about £18 per month on average.
However, it’s important to remember that the price cap is not a cap on your bill. It limits the unit rates suppliers can charge for gas and electricity, plus standing charges. What you actually pay will always depend on your usage. [forbes.com], [infinity-e…ergy.co.uk]
What’s driving the increase?
Several forces have combined to push the cap higher this quarter:
1. Wholesale gas prices remain the dominant factor
Wholesale energy costs—particularly gas—make up a large share of household bills (around 40%).
Prices have surged in recent months, rising by more than 25–28%, largely due to geopolitical tensions in the Middle East disrupting supply routes. [aol.com] [forbes.com], [aol.com]
2. Gas is rising faster than electricity
The latest cap reflects gas prices rising by around 24%, compared with a more modest 5% increase for electricity.
This gap reflects a growing contribution from renewables in electricity generation, which is helping to dampen power price inflation, even as gas remains volatile. [forbes.com]
3. The cap adjusts quarterly—and quickly
Because Ofgem updates the cap every three months, it responds relatively quickly to market changes—both up and down.
While prices fell in April thanks to lower wholesale costs and policy changes, the latest spike shows how quickly the trend can reverse. [ofgem.gov.uk]
The key change: “typical usage” is being revised
Alongside the price rise, one of the most important (and less widely understood) changes is the potential revision to expected household energy usage, known as the Typical Domestic Consumption Values (TDCVs).
Ofgem has been consulting on lowering these “typical usage” assumptions to reflect the fact that households are using less energy than in the past. [uswitch.com]
For example:
- A medium household benchmark could fall from around 2,700 kWh to 2,500 kWh (electricity)
- And from 11,500 kWh to 9,500 kWh (gas) [uswitch.com]
Why does this matter?
Because the headline price cap figure (e.g. £1,862) is based on these “typical” usage levels. If Ofgem lowers the assumed consumption:
- The headline cap figure may appear lower than expected
- Even if the actual unit rates (what you pay per kWh) are still rising
In other words, a lower “typical bill” does not necessarily mean energy is cheaper—it may simply reflect an assumption that households are using less.
What it means for household costs
For families, the real-world impact depends on your usage:
- Average-use households: Expect bills to rise broadly in line with the £200+ annual increase
- Higher-use households (larger homes, families, home workers): Likely to see bigger increases, particularly due to higher gas costs
- Lower-use households: May see smaller increases—but standing charges still apply regardless of usage
It’s also worth noting:
- Around 19 million households are on tariffs affected by the cap [aol.com]
- Those on fixed-rate deals won’t see immediate changes, but new fixes are likely to become more expensive [forbes.com]
What should savers and households take away?
While the summer months typically bring lower energy usage, the direction of travel is clear: energy costs remain highly exposed to global events, particularly gas markets.
There are three key implications:
1. Budgeting remains essential
Even moderate increases can add pressure over time, particularly as energy still costs significantly more than pre-2022 levels.
2. The headline “cap” can be misleading
Changes to typical usage mean that comparing headline figures alone can give a distorted view. Focus instead on unit rates and your own consumption.
3. Volatility isn’t going away
With further increases possible later in the year, households may want to review fixed deals, build a financial buffer, or look at ways to reduce consumption where possible.
In summary: today’s announcement is a reminder that while energy bills have eased from their peak, they remain unpredictable. Understanding not just the headline cap—but the factors behind it—can help households stay in control of their finances in the months ahead.
