Do Solar Panels Increase Property Value in the UK?
Evidence from Rightmove, Halifax, and the Energy Saving Trust suggests solar panels can add thousands to your home's value — but the amount depends on your system, EPC rating, and whether you own or lease the panels.
Quick Answer
Yes. Evidence from Rightmove, Halifax, and the Energy Saving Trust suggests solar panels add 0.5–2% to property value. Homes with an EPC rating of A–C sell for a premium over lower-rated properties. A typical 4kW system costing around £8,000 could add £8,000–£15,000 to your home’s value in 2026.
Do solar panels add value to your home?
Yes. Multiple UK studies confirm that solar panels add measurable value to residential property. The strongest driver is the improvement to your Energy Performance Certificate (EPC) rating — homes rated EPC A–C consistently sell for more than those rated D or below.
A 2026 analysis by Rightmove found that energy-efficient homes command a premium of up to 16% compared to similar properties with lower EPC ratings. Halifax mortgage data shows that homes with EPC A or B ratings sell for an average of £30,000 more than EPC D properties.
The Energy Saving Trust notes that solar PV is one of the most cost-effective ways to improve your EPC rating, often pushing a home from D to C or from C to B. This rating improvement alone can add significant value before accounting for the appeal of lower energy bills.
Buyer demand for energy-efficient homes is growing. Rightmove data shows that 14% of UK buyers now prioritise energy efficiency when searching for a home, up from just 3% in 2019. With energy prices remaining volatile, this trend is accelerating.
How much value do solar panels add?
The value solar panels add depends on the system size, whether you include battery storage, and your local property market. Below are typical figures based on UK market data and installer feedback.
| System | Typical Cost | Estimated Value Added | Net Gain |
|---|---|---|---|
| 3kW system (8–10 panels) | £6,000 | £6,000–£10,000 | £0–£4,000 |
| 4kW system (10–12 panels) | £8,000 | £8,000–£15,000 | £0–£7,000 |
| 4kW + battery storage | £12,000 | £12,000–£20,000 | £0–£8,000 |
These figures reflect the combination of EPC improvement, lower running costs, and buyer demand for energy-efficient homes. The higher end of the range applies to areas with higher property values, such as London and the South East.
Why solar increases property value
Lower Energy Bills
A typical 4kW system saves £800–£1,200 per year on electricity bills. Buyers recognise that lower running costs make the property more affordable to live in over the long term.
EPC Rating Improvement
Solar panels typically improve your EPC by 1–2 bands (e.g. D to C, or C to B). Higher EPC ratings correlate directly with higher sale prices across all UK regions.
Future-Proofing Against Energy Prices
With energy prices remaining volatile since the 2022 crisis, homes that generate their own electricity are increasingly attractive. Self-generation provides a hedge against future price rises.
Growing Buyer Demand
14% of UK property searches now include energy efficiency as a priority factor. As awareness of running costs grows, demand for solar-equipped homes continues to rise.
EPC rating impact
Your Energy Performance Certificate (EPC) rating is one of the strongest predictors of property value. Solar panels are one of the most effective ways to improve your rating.
| EPC Band | Typical Price Premium vs EPC D | Solar Impact |
|---|---|---|
| A (92–100) | +£40,000–£60,000 | Solar + battery + insulation usually needed |
| B (81–91) | +£20,000–£40,000 | Solar alone can achieve this from C |
| C (69–80) | +£5,000–£15,000 | Solar alone can achieve this from D |
| D (55–68) | Baseline | — |
Solar PV typically adds 10–20 EPC points to your score. If your home currently sits at the lower end of a band (e.g. EPC D with a score of 60), solar alone may be enough to push you into band C.
Rental properties
The UK government has proposed a minimum EPC C rating for rental properties by 2030. Landlords installing solar now will be ahead of regulations and avoid last-minute costs.
Does solar ever decrease property value?
In most cases, no. However, there are situations where solar panels can make a property harder to sell or even reduce its appeal:
Leased or PPA panels
If your panels are leased or under a Power Purchase Agreement (PPA), the buyer must agree to take over the contract. Some buyers (and mortgage lenders) are reluctant to do this, which can slow or complicate the sale.
Poor aesthetics on period or listed homes
Panels on the front elevation of a period property or in a conservation area may put off buyers who value the home's character. Rear or side installations, or in-roof systems, can avoid this issue.
Maintenance concerns
Some buyers worry about maintenance, roof access, and inverter replacement costs. Providing warranty documents and generation data helps overcome this. Modern systems require very little maintenance.
Roof condition
If the roof needs replacing within 10 years, panels will need to be removed and refitted at additional cost (typically £1,000–£2,000). A surveyor may flag this. Ensure your roof is in good condition before installing.
Selling a home with solar panels
To maximise the value solar adds to your sale, have the following documents ready for buyers and their solicitors:
MCS Certificate
Proof that the system was installed by an MCS-certified installer. This is required for Smart Export Guarantee (SEG) payments and confirms compliance with building regulations.
Warranty Documents
Panel manufacturer warranty (typically 25 years) and inverter warranty (typically 10–15 years). These transfer to the new owner automatically.
Generation Data
Screenshots or exports from your monitoring app showing actual annual generation. Real data is more convincing than estimates and helps buyers calculate their savings.
DNO Approval
Confirmation that your Distribution Network Operator (DNO) was notified of the installation. This is a standard requirement for grid-connected systems.
SEG Contract Details
If you're receiving Smart Export Guarantee payments, provide details of your tariff and supplier. The new owner can set up their own SEG contract.
EPC Certificate
Your updated EPC reflecting the solar installation. If your EPC predates the panels, get a new assessment — it will show the improved rating and estimated energy costs.
Leased vs owned solar panels
Whether you own or lease your panels makes a significant difference to how they affect your property value and saleability.
| Factor | Owned Panels | Leased / PPA Panels |
|---|---|---|
| Property value impact | Adds clear, measurable value | May add little or no value |
| Sale process | Straightforward — panels included in sale | Buyer must agree to take over contract |
| Mortgage lender view | No issues | Some lenders are cautious or refuse |
| Buyer perception | Seen as an asset | May be seen as a liability |
| SEG income | Transferable to new owner | Depends on PPA terms |
If you have leased panels and are considering selling, check your contract for early termination options. Some PPA providers will allow you to buy out the remaining lease, which removes the complication for potential buyers.
Frequently Asked Questions About Solar Panels & Property Value
Do solar panels increase house prices in the UK?
Yes. Evidence from Rightmove, Halifax, and the Energy Saving Trust shows that solar panels typically add 0.5-2% to property value, primarily through EPC rating improvements and lower running costs.
How much do solar panels add to house value?
A typical 4kW system costing around £8,000 can add £8,000–£15,000 to your home’s value. Adding battery storage increases the premium further, with a 4kW + battery system potentially adding £12,000–£20,000.
Do estate agents value solar panels?
Increasingly, yes. Estate agents report that buyers are asking about energy efficiency more than ever. Solar panels are now featured as a selling point in property listings, particularly since energy prices rose sharply in 2022.
Do solar panels affect my mortgage?
Owned solar panels do not affect mortgage applications. However, leased or PPA panels can cause issues with some lenders, as the lease creates a charge on the property. Most major lenders now accept leased panels, but it can slow the process.
Can I claim back VAT on solar panels?
Solar panels for domestic properties are currently charged at 0% VAT in the UK (extended through to March 2027). This means you pay no VAT on the supply and installation of solar panels, batteries, and related equipment.
Do solar panels make a house harder to sell?
Owned panels generally make a property easier to sell due to lower running costs and better EPC ratings. Leased or PPA panels can complicate sales if the buyer or their lender is unwilling to take over the contract.
What happens to solar panel warranties when I sell?
Panel and inverter warranties typically transfer automatically to the new owner. MCS certificates and warranty documents should be passed to the buyer as part of the sale. There is usually no need to contact the manufacturer.
Should I install solar panels before selling my house?
If your home has a low EPC rating (D or below), installing solar before selling can be worthwhile. The EPC improvement alone can add more value than the installation cost. However, if you are selling within 6 months, the payback period may not justify the investment.
