Why 2025 is the best time to go solar in the UK
With energy prices still high and battery storage getting smarter, 2025 is a standout year for UK homeowners to secure a solar and battery deal that cuts bills, boosts energy independence and protects against future price hikes.
Lower your bills
Use free solar power during the day and stored energy in the evening. Typical homes cut grid use by 60–80% with solar plus battery.
Store cheap electricity
Charge your battery from the sun or off-peak tariffs. Run your home when prices are highest and sell surplus back to the grid.
Add value to your home
Well-specified solar and battery systems are increasingly attractive to buyers and can improve your EPC rating.
*Savings depend on system size, usage and tariff. Our partners will provide a personalised projection for your property.

Best solar panel brands and battery options in 2025
The "best" solar deal for your home isn’t just the cheapest price — it’s the right mix of panel quality, battery capacity, inverter technology and warranty. Here are some of the brands and options you can expect to see in UK quotes during 2025.
Popular solar panel choices
Most homeowners choose high-efficiency monocrystalline panels that balance performance, aesthetics and price. Common panel options include:
- Premium panels (higher efficiency, sleek black finish, longer warranties)
- Value panels (excellent cost per kWh, ideal for larger roofs)
- All-black or in-roof options for improved kerb appeal
Panel output in 2025 typically ranges from 400W to 450W+ per module, allowing more power from the same roof area than systems installed just a few years ago.
Home battery storage options
Battery deals usually focus on lithium-ion batteries with smart control systems. Common sizes and features include:
- 5kWh batteries — for smaller homes or those testing storage for the first time
- 10–15kWh batteries — for family homes, EV drivers and heat pump users
- Smart charge/discharge based on tariff, weather and usage patterns
- Optional backup circuits to keep key appliances running during power cuts
A well-sized battery can use around 70–90% of your solar generation on-site, instead of exporting it for a lower SEG rate.
How much can you save with solar panels and a battery?
Actual savings depend on your usage, roof size, shading and tariff, but the examples below give a realistic idea of what homeowners are seeing in 2025.
£600+
Typical annual saving with solar only on a 3-bed home
£1,000+
Annual saving with solar + battery and smart tariff
6–10 yrs
Typical payback period for well-specified systems

UK grants, VAT and incentives for solar & batteries in 2025
Government policy continues to support home renewable energy in 2025. While national grants can change, there are several schemes and incentives that can significantly improve your payback time.
0% VAT on home solar (subject to rules)
The UK currently offers a reduced VAT rate on many residential energy-saving measures, including solar panels, which helps bring down the overall cost of installation.
Installers will confirm how VAT is applied to your system based on the latest rules at the time of your quote.
Smart Export Guarantee (SEG)
With SEG, energy suppliers pay you for each kWh of surplus solar electricity you export back to the grid.
- Tariffs vary by supplier — our partners can help you compare.
- You need an MCS-certified installation and a smart meter.
- Pairing SEG with a battery and flexible tariff can maximise returns.
Local and regional support
Some councils, devolved governments and housing schemes offer extra funding, loans or support for renewable upgrades.
Our solar partners keep track of regional incentives and will highlight anything you may qualify for during your quote.
Energy-efficient home upgrades
Combining solar with other measures like insulation, heat pumps or smart heating controls can unlock additional funding and reduce your overall energy use.
Let us know if you are planning wider home improvements and we can connect you with the most suitable packages.
Information about grants and incentives can change. Always check the latest official guidance or speak to a qualified advisor. Our partners will outline any available support in your proposal.
Frequently asked questions about solar panel and battery deals in 2025
Still deciding if solar is right for your home? These are some of the most common questions UK homeowners ask when comparing 2025 solar and battery offers.
Yes. Despite some energy price movements, electricity costs remain high compared to historic levels, and UK solar technology has never been more efficient. With a battery, many households now achieve payback in 6–10 years, then enjoy largely free electricity for another 15 years or more.
Panels alone can still offer strong savings if you use plenty of electricity during daylight hours. However, a battery lets you store surplus energy for evenings and cloudy periods, and can increase your self-consumption to 70–90%. Our advisors can model both options so you see the difference in payback and long-term returns.
South-facing roofs usually give the best performance, but east/west and even some north-facing roofs can still be viable, especially when paired with high-efficiency panels and optimisers. Your quote will include a generation estimate based on your exact roof orientation, shading and postcode.
Most standard roof-mounted solar installations on houses fall under permitted development and do not require planning permission, provided certain limits are met. Exceptions include listed buildings, conservation areas and some flats or shared roofs. Your installer will confirm whether permission is required in your case.
Once you accept a quote, most home solar projects are installed in 1–3 days, depending on system size and roof complexity. Batteries and EV chargers may add a little time. The full process from quote to switch-on is often 3–6 weeks, subject to survey and grid approvals.
Solar PV systems have no moving parts and require very little maintenance. Rain usually keeps panels clean enough for normal performance. Batteries and inverters are monitored via apps and may receive software updates over time. Installers typically offer optional maintenance packages and will explain how to keep your system running efficiently.
Yes. Many 2025 battery deals are designed specifically for homes that already have solar panels installed. Depending on your existing inverter, you may be able to add an AC-coupled battery that works alongside your current system, or upgrade to a hybrid inverter for extra flexibility.
Absolutely. Solar, batteries, EV chargers and heat pumps can all work together to dramatically reduce your reliance on the grid. Smart systems can prioritise charging your car during sunny periods or pre-heating your home when energy is cheapest. Let us know which technologies you have (or plan to install) so your quote can be optimised around them.
