How to future proof your home against global energy price changes

We’ve all seen the headlines. The global energy market has been a bit of a rollercoaster recently. As of April 2026, the energy price cap is £1,641. While that is lower than the record peaks we’ve seen, the 24.67p/kWh unit rate is still about 35% higher than what we were paying back in 2021.

If you’re tired of checking the news for the latest price cap announcement, it might be time to change your approach. Future proofing your home isn't just about switching to a slightly cheaper supplier anymore. It’s about energy resilience. By reducing how much you rely on the grid, you can protect your household from rising energy bills and volatile market prices.

Why solar panels are only half the story.

When people think about renewable energy, they usually picture rows of glass on a south-facing roof. While solar panels in the United Kingdom are more efficient than ever, installing them without a way to store that power is a bit like catching rain in a bucket with a hole in the bottom.

The self consumption challenge.

Without a home battery, the typical UK household only uses about 30% of the energy they generate. This means that while your panels are soaking up the midday sun, most of that green energy is sent back to the grid because you aren't home to use it. When you get home at 6pm and turn on the oven, the sun is setting. You’re then forced to buy power back from the grid at peak rates.

Using home energy storage benefits to your advantage.

This is where home energy storage benefits really help. By adding a battery, you can store the extra solar energy generated during the day. You can then use it during the expensive 4pm to 7pm surge, which helps reduce your grid usage when it costs the most.

With high efficiency lithium iron phosphate batteries, you can even get and store energy from the grid when it's cheapest. This involves charging your battery from the grid during the night when rates are lowest, perhaps using a smart tariff like Next Smart Saver, and using that cheap stored power during the day.

Working out your savings and return on investment in 2026.

One of the biggest questions we get is whether solar is still worth it. The short answer is yes. The numbers are actually more convincing than they were five years ago.

For a high performing setup including a 5.82 kWp solar array with 12 panels and a 5.1 kWh battery, the estimated annual saving is around £1,2071.

The 0% VAT advantage.

The UK government has extended the 0% VAT rate on solar and battery installations until March 2027. This lowers the purchase and installation cost of your system. Currently, the average time it takes for a full system to pay for itself is between 7 and 10 years2.

Potential impact on energy bills. 

Think of solar savings as a way to lower your household overheads. While interest earned in a bank account can be subject to tax once you exceed your personal allowance, every pound you don't have to pay to an energy supplier is money that stays in your pocket.

Note: Actual savings vary by location and usage. A home in Scotland or a property with a lot of shade will see different results than a south-facing home in the Midlands.

Solar panel finance in the UK: Making the switch affordable.

We know that the upfront cost of solar panels can be a hurdle. That’s why solar panel finance has become a helpful tool for homeowners who want to produce and use their own energy.

0% APR for 2 years with E.ON Next.

We’ve introduced a £0 upfront, 3-year 0% finance* offer to help you get started. This pay as you save approach lets you spread the cost of the installation without paying any interest. We also make sure you have peace of mind with:

• MCS certified installations: Every system is installed by accredited experts to ensure it works safely and efficiently.

Understanding the total benefit of solar.

To really see how to protect yourself against rising energy bills, it helps to look at the two ways a solar and battery system saves you money.

1. Avoided costs: This is the money you don't pay to the grid because you’re using your own sunshine. For a typical 12-panel system, this makes up about £7714 of your annual gain.

2. Export income: Thanks to the Smart Export Guarantee, you can earn money for the extra energy you don't use. We pay 17.5p/kWh for the energy you share back with the community. This can add about £4125 to your yearly totals.

Take control of your roof.

You can't control global energy markets or the decisions of the national grid. But you can control your roof. By investing in solar power and storage today, you aren't just buying equipment, you’re increasing your energy certainty. 

With 0% VAT available for a limited time and flexible solar panel finance in the UK, it’s a great time to make the switch.
