The average UK home sold in 2024 with solar panels already installed changed hands for 4% more than an identical property without them, roughly £10,000 on a typical semi-detached house. That figure, from analysis by the estate agency comparison site GetAgent, is the closest the market has to a hard number on a question that has long been debated in estate agent particulars and kitchen-table conversations alike.
As reported by vocal.media, the headline figure masks a much messier reality. The premium is not uniform. It depends on who owns the panels, how old they are, whether the house has an EPC rating above C, and even which region the property sits in. For a homeowner considering an installation, understanding these nuances is worth far more than the average.
Owned versus leased, the split that changes everything
The single biggest determinant of value-add is ownership. A solar PV system that a homeowner owns outright, either paid for up front or via a zero-interest loan, typically commands a premium of 4–8% on sale. The buyer inherits the asset, the Feed-in Tariff or Smart Export Guarantee payments, and the ongoing bill savings. That is a clean value proposition.
But a system installed under a lease or a power purchase agreement (PPA) is a different story. In those cases, the panels are owned by a third party, the buyer must take over the contract, and the savings are often smaller. Estate agents report that such arrangements can actually reduce a property’s value, because buyers perceive them as a complication rather than a benefit. The Energy Saving Trust advises homeowners to check whether their contract can be transferred or bought out before listing.
EPC ratings and the £16,000 uplift
The second factor is the property’s Energy Performance Certificate. Solar panels typically lift a home from EPC band D to C, or from C to B. That jump is valuable in itself. Research by Nationwide Building Society found that homes with an EPC rating of A or B sell for an average of 16% more than those rated D or E. On a £250,000 property, that is £40,000, though solar alone will not achieve the full uplift without accompanying insulation and heating improvements.
Ofgem’s latest data shows that a typical 3.5 kWp solar array generates around 3,000 kWh per year, saving a household roughly £450 on electricity bills at current price cap rates. Over a 25-year lifespan, that is £11,250 in avoided costs, plus export payments of around £150 a year under the Smart Export Guarantee. A buyer who capitalises those savings into a purchase price is effectively paying for a decade of free electricity.
Regional premiums and the buyer’s mindset
The premium also varies by region. In the South East and South West, where average electricity consumption is lower but unit costs are higher, solar panels add more value, up to 8% in some postcodes. In Scotland and the North East, where sunlight hours are fewer, the premium is closer to 3–4%. The market is rational: buyers pay more where the panels generate more savings.
What this misses is the behavioural shift. A 2023 survey by the HomeOwners Alliance found that 62% of prospective buyers rated energy efficiency as a top-three factor in their decision, up from 38% in 2019. Solar panels are no longer a niche eco-feature; they are a mainstream selling point, particularly for first-time buyers and families worried about future bill rises.
The catch is timing. Homes with panels installed before 2019, when the Feed-in Tariff closed to new applicants, still attract a premium because those tariffs pay higher rates. Systems installed after that earn only the Smart Export Guarantee, which pays roughly a third of the old rate. Buyers are now savvy enough to ask which scheme the panels are on.
For a homeowner considering an installation today, the decision is straightforward if they plan to stay in the property for five years or more. The typical £7,000–£9,000 cost of a 3.5 kWp system is recouped in bill savings and export payments within 8–12 years, and the value uplift on sale covers the remainder. For those planning to move sooner, the premium may not fully offset the upfront cost, but it will still make the house easier to sell.
Households on standard variable tariffs considering solar should get at least three quotes from MCS-certified installers, check whether their roof orientation and shading allow for optimal generation, and ensure the system is owned outright from day one. The market has spoken: owned solar adds value. Leased solar adds questions. The difference is thousands of pounds.
Frequently Asked Questions
No. Owned systems typically add 4–8% to the sale price, but leased or PPA systems can deter buyers and may not add any value. The condition, age, and output of the panels also matter. An MCS certificate and proof of generation are essential documentation for a sale.
A typical 3.5 kWp system costs between £7,000 and £9,000 installed. With annual savings of around £450 on bills and £150 in Smart Export Guarantee payments, the payback period is 8–12 years. The value uplift on sale typically covers the remaining cost if you move before then.
