# UK Energy Price Cap October 2026: What It Means for Your Bills — and Whether Solar Can Help
If you've noticed another change to energy prices this autumn, you're not imagining it.
The latest Ofgem energy price cap came into effect on 1 October 2026, and prices for a typical household on a default tariff have risen by around 4%.
At the same time, VAT has temporarily been removed from household electricity bills.
So what will you actually pay? And with energy prices continuing to change, does generating and storing more of your own electricity now make more sense?
Here's the straightforward answer.
What is the new energy price cap from October 2026?
For households on a standard variable tariff paying by Direct Debit, Ofgem's average rates across England, Scotland and Wales from 1 October to 31 December 2026 are:
- Electricity: 26.32p per kWh
- Electricity standing charge: 54.83p per day
- Gas: 7.97p per kWh
- Gas standing charge: 29.68p per day
These are averages rather than a fixed maximum bill.
Your actual bill depends on how much energy you use, where you live, your meter and your tariff.
If you use more energy, you still pay more.
Has electricity VAT really been removed?
Yes.
From 1 October 2026 to 31 March 2027, VAT has been removed from household electricity bills.
The government estimates this will save households around £45 per year on average, although the actual saving depends on electricity consumption.
Gas continues to attract VAT.
The change helps, but it doesn't remove the bigger question facing homeowners:
How much electricity will your home need to buy from the grid in the first place?
That's where technologies such as solar panels and battery storage become interesting.
Could solar panels reduce the impact of higher electricity prices?
Potentially, yes.
Solar panels generate electricity at your property.
Every unit of solar electricity that you generate and use yourself is a unit you don't need to buy from your electricity supplier at the prevailing retail rate.
For example, your panels may generate electricity while you're:
- running the washing machine
- working from home
- charging appliances
- heating water with suitable equipment
- charging an electric vehicle
- running a heat pump
But the amount you could save depends heavily on your roof, system size and electricity usage.
Solar shouldn't be sold as a guaranteed percentage reduction in everybody's bill.
New UK evidence makes solar + batteries particularly interesting
A major UK trial published in September 2026 provides some of the strongest recent evidence of what solar combined with battery storage can achieve.
The Centre for Net Zero studied 708 households receiving solar panels and battery storage.
It found that electricity bills fell by around 62% on average, equivalent to approximately £681 per year in the trial.
Net electricity imported from the grid fell by 77%, while grid imports during the 4pm–8pm peak fell by 66%.
Those are impressive numbers.
But there's an important warning:
They are results from that particular trial — not a promise that installing solar and a battery will cut your bill by 62%.
Your property could perform differently.
Why can adding a battery change the calculation?
Solar panels usually produce the most electricity during daylight hours.
Unfortunately, many households use a lot of electricity in the evening.
Without a battery, surplus daytime solar electricity may be exported to the grid.
A home battery gives you another option:
- Your panels generate electricity during the day.
- Your home uses what it needs.
- Surplus electricity charges the battery.
- The battery can supply electricity later when the sun isn't shining.
Some batteries can also charge using cheaper off-peak grid electricity, depending on your tariff and equipment.
That can reduce the amount of higher-priced electricity you need to buy at other times.
Solar panels or solar + battery: which should you choose?
There isn't one answer for every home.
Solar alone may make sense if:
- You use significant electricity during daylight hours
- You have a suitable unshaded roof
- You want to keep the initial installation cost lower
- You can move appliances or EV charging into daylight hours
Solar plus battery storage may be worth investigating if:
- You use substantial electricity in the evening
- Your solar panels would otherwise export a lot of surplus generation
- You want to increase solar self-consumption
- You're considering a time-of-use electricity tariff
- You want to buy less electricity from the grid during expensive periods
The important word is investigating.
An installer should model your property and electricity usage rather than simply recommending the largest battery they sell.
What about plug-in solar panels?
There's another important 2026 development.
Plug-in solar panels became legal to use across Great Britain in August 2026.
The government says compliant systems can provide up to 800W of power and potentially supply up to 20% of an average home's electricity use, with possible savings of up to £110 per year.
They're very different from a conventional rooftop solar installation.
A professionally designed rooftop system can be substantially larger and may be combined with battery storage, an EV charger or other home-energy technology.
Which approach is appropriate depends on your property, budget and energy goals.
Can you still get paid for exporting solar electricity?
Yes, subject to eligibility.
The Smart Export Guarantee allows eligible households to receive payments for renewable electricity exported to the grid.
Export rates vary between suppliers.
That means electricity generated by rooftop solar can potentially provide value in three ways:
- Use it immediately instead of buying electricity from the grid
- Store it in a battery and use it later
- Export surplus electricity and receive an export payment
A good solar quote should explain the assumptions being made about all three.
What should you compare when getting solar quotes?
Don't compare installers on headline price alone.
Ask each installer for:
- Proposed solar system size in kWp
- Estimated annual generation
- Panel manufacturer and model
- Inverter manufacturer and model
- Battery capacity if included
- Product warranties
- Workmanship warranty
- Expected self-consumption
- Export assumptions
- Estimated annual savings
- Scaffolding and electrical work
- Total installed price
Most importantly, ask them to explain how they calculated the savings figure.
If one quote promises dramatically higher savings than the others, find out why.
What about heat pumps?
A heat pump is different because it tackles your home's heating rather than generating electricity.
It uses electricity to move heat into your home and can replace gas, oil or LPG heating in suitable properties.
Installation cost, insulation, radiator sizing, heat loss and electricity tariff all affect whether a heat pump makes financial sense.
Government support may also be available depending on where you live and whether your property qualifies.
If you're considering both solar and a heat pump, it's worth telling installers.
A future heat pump increases your electricity consumption, which can affect the appropriate size of a solar and battery system.
So, should you install solar because the price cap has risen?
Not solely because of one quarterly price-cap movement.
Solar panels are a long-term home improvement, while energy prices can move up and down.
A better question is:
Would solar make financial sense for my particular home across many years?
Consider:
- Your roof orientation and shading
- Annual electricity consumption
- When you use electricity
- How long you expect to remain in the property
- Whether you're considering an EV or heat pump
- Installation cost
- Export tariff
- Whether battery storage suits your usage
Then compare actual installer proposals.

Frequently asked questions
What is the electricity price cap rate from October 2026?
For 1 October to 31 December 2026, Ofgem says the average electricity unit rate for a standard variable tariff paid by Direct Debit is 26.32p/kWh across England, Scotland and Wales. The average electricity standing charge is 54.83p per day. Actual rates vary by region, meter and payment method.
Did energy prices increase in October 2026?
Ofgem says prices under the cap increased by around 4% for a typical dual-fuel household paying by Direct Debit from 1 October 2026.
Is there VAT on electricity in October 2026?
The government removed VAT from household electricity bills from 1 October 2026 until 31 March 2027. Gas VAT remains in place.
Will solar panels eliminate my electricity bill?
Usually not completely. Solar generation changes throughout the day and year, and most homes still import some electricity from the grid. Battery storage can increase the proportion of your solar generation you use yourself.
How much could solar and battery storage save?
It depends on the property and household. A 2026 UK trial involving 708 households found an average electricity bill reduction of around 62%, or £681 per year, after solar and battery installation. That result should not be treated as a forecast for an individual property.
Should I get more than one solar quote?
Comparing several quotes can reveal significant differences in system size, equipment, warranties, projected generation and price. Home Energy Match can match homeowners with up to three relevant installers covering their postcode.
