UK Sees Surge in Solar Panel Demand Amid Rising Energy Costs
- Published
Solar panel sales have risen sharply since the start of the Middle East conflict, according to Octopus Energy - with households opting for larger arrays of roof panels. Sales were up 50% since after the war pushed oil and gas prices up.
Consumer expert Holly Hamilton explains whether they are worth your cash, and the grants available that could help you get them installed in your home. Plus, how, in just a few months' time, you could be able to buy plug-in solar power from supermarkets.
Energy Prices Push Households Toward Solar.
The UK is experiencing a sharp rise in demand for solar panels as households look for ways to shield themselves from rising energy bills and global market instability.
Industry analysts say the surge is being driven by a combination of higher energy prices, falling installation costs and rapid improvements in home energy technology. Many households are now turning to solar as a way to gain greater control over their energy use.
Rising global energy prices, intensified by geopolitical instability, have pushed up the cost of oil and gas. With the energy price cap set to reset in July, many households expect bills to rise again and are acting early to reduce their exposure.
Solar energy is increasingly seen as a route to energy independence, offering families a buffer against future price shocks.
Costs Fall as Technology Improves
The cost of solar systems has dropped by around 40% since 2020, and installations currently benefit from zero VAT. This has made solar more accessible to a wider range of households.
There has also been a significant shift in technology. More homeowners are pairing panels with battery storage, allowing them to store electricity for use when prices are higher or sunlight is limited. While battery systems remain relatively expensive, with only around one in 20 homes currently using them, they are becoming more affordable.
Take up varies across the country, with the south west of England seeing the highest adoption rates.
Pros and Cons of Solar Panels
Experts say solar panels can offer substantial benefits, but they are not suitable for everyone.
Pros
Lower energy bills: Households can cut bills by 55 to 75 percent depending on system size and usage.
Greater energy security: Solar provides a hedge against future price rises, especially when paired with a battery.
Faster payback periods: Falling costs mean households can recover their investment more quickly.
Environmental benefits: Solar reduces carbon emissions and reliance on fossil fuels.
Cons
High upfront cost: A typical system costs upwards of £6,000, with batteries adding significantly more.
Weather dependent output: Solar generation drops in winter, meaning households still rely on the grid.
Potential price rises: Supply chain pressures, including shipping and lithium costs, may push system prices up by 10 to 15 percent in the short term.
Variable savings: Benefits depend on household energy use, system size and tariff.
Policy uncertainty: Changes to tariffs or government incentives could affect long term returns.
Plug In Solar Kits Set for UK Launch
A new wave of plug in solar kits, already popular in Germany, could soon make solar more accessible to renters and people living in flats.
These compact systems, costing only a few hundred pounds, can be placed on balconies, gardens or shed roofs and plugged directly into a standard 3 pin socket. They are capped at 800W for safety and are not designed to power an entire home, but can offset the cost of running small appliances such as a small fridge or Wi Fi router.
Retailers including Lidl, Amazon and Iceland are preparing to stock the kits once new government safety rules are finalised, expected in summer 2026.
Grants and Schemes Available
Several schemes are available to help households with the cost of installing solar panels.
Warm Homes (England)
A major scheme offering fully funded upgrades, including solar panels, for low income households (typically under £36,000) living in inefficient homes (EPC D to G). Grants can exceed £15,000 and are available to homeowners and private tenants with landlord permission.
ECO4 Scheme (England, Wales and Scotland)
Funded by energy suppliers, ECO4 provides free or heavily subsidised solar panels, insulation and heating upgrades for households on certain benefits or low incomes. The scheme runs until the end of 2026.
Smart Export Guarantee (SEG)
Not a grant, but a payment scheme where households earn 5 to 15p per kWh for electricity exported back to the grid. Systems must be installed by an MCS certified or equivalent installer.
