Solar panels and house prices Do solar panels add value to your home?

What the evidence says about house prices

• Solar Energy UK, the industry body, puts the average uplift at 0.9% to 2%. Its 2021 analysis of Land Registry data found a typical gain of around £1,800 (reported by Which?, April 2026).
• Estate agents asked by Which? mostly said solar panels don't typically increase a property's value, but can make it easier to sell. One said panels don't usually change the formal valuation, though someone might offer more for a house with them than without.
• Some agents see a price premium in particular cases. One told Which? they had seen buyers pay more where a Feed-in Tariff had several years left to run. Another said panels could add value in parts of the housing market where buyers tend to be younger and more eco-conscious, giving Cambridge as an example.
• NAEA Propertymark told MoneySavingExpert that in the short term, panels don't provide an increase in house value.

Claims of much bigger uplifts, up to 14%, are usually unsourced, and Which? describes the research as mixed. The honest answer is that panels are more likely to help a sale go smoothly than to add a large sum to the price. That could change as solar becomes more common: the government counted 182,000 new installations on homes in 2025, a record year.

Lower electricity bills: the bigger financial benefit

For most people the real return comes from lower energy bills, not the sale price. MoneySavingExpert, quoting the Energy Saving Trust, says a 4.5 kWp system cuts bills by £190 to £330 a year at price cap rates, before any export income, and the Energy Saving Trust's payback estimates, including export payments, run from 9 to 12 years. For the full sums, see are solar panels worth it?

Rising energy costs

Ofgem's price cap rose 4% from 1 October 2026, taking a typical dual-fuel bill from £1,663 to £1,723 a year. Every unit of solar electricity you use yourself is one you don't buy at those electricity prices, so higher prices make the panels worth more to you, and to a buyer comparing energy bills between homes.

Self-consumption and the Smart Export Guarantee

Surplus electricity you don't use is exported to the grid, and the Smart Export Guarantee (SEG) pays you for it. When we checked, the Energy Saving Trust worked on around 12p a unit for export, while grid electricity costs more than twice that. So self-consumption, using the electricity you generate yourself, saves more than exporting earns. See the Smart Export Guarantee.

Solar PV with battery storage and heat pumps

Battery storage keeps daytime solar for the evening, and homes with heat pumps or electric vehicles use more electricity, so they can use more of the energy generated. The Energy Minister, quoted by MCS, said a household could save up to £550 a year by installing a heat pump, solar PV and a battery together. We haven't found UK evidence on whether a battery adds more to a sale price than panels alone.

Owned panels vs leased panels (rent-a-roof)

This is the one situation where solar can make a sale harder. Some "free solar" deals from years ago, often called rent-a-roof schemes, gave a company a long lease on your roof in return for the panels. MoneySavingExpert warns these give the company the right to use your roof, and that selling a home with one may not be straightforward, because buyers and their lenders have to accept the lease.

Panels you own outright don't have this problem. If you're buying, ask whether the panels are owned or leased before you go any further.

Buying a home with solar panels

• Ask whether the panels are owned or leased. If they're leased, read the lease and check your lender will accept it.
• Ask for the MCS certificate and the electrical certificate.
• Check the age of the inverter. The Energy Saving Trust says inverters need replacing after around 12 years.
• Ask for recent generation figures and any Feed-in Tariff details, so you can see what the system makes.
• Arrange how you'll be paid for exported electricity once you move in. Under the Smart Export Guarantee you can choose any SEG supplier, not just the one you buy electricity from.
