Do Solar Panels Increase House Value?
Research consistently shows solar panels add 4–14% to UK property values. Here is the evidence, the numbers, and how to maximise the return on your investment.
The Evidence: Solar Panels and Property Value
Multiple studies have confirmed that solar panels add measurable value to UK homes. A 2023 analysis of 100,000+ property transactions found that solar-equipped homes sell for an average of 4.1% more than comparable non-solar properties. With rising energy costs, this premium is growing.
For Midlands homeowners, a typical 4kW solar installation costing £6,500–£8,000 could add £10,000–£25,000 in property value, depending on the home location, current EPC rating, and market conditions.
How Solar Panels Affect Your EPC Rating
The Energy Performance Certificate (EPC) is one of the most important factors in property value and mortgage eligibility. Solar panels typically improve an EPC rating by 1–2 bands — moving a property from D to B, or E to C.
This matters increasingly because mortgage lenders increasingly offer better rates for high EPC properties, proposed future legislation may require rental properties to reach EPC C or above, and buyers looking to minimise running costs prioritise higher-rated properties.
Return on Investment — Typical Midlands Home
| Metric | Value | Note |
|---|---|---|
| System Cost | £7,500 | 4kW solar + battery |
| Annual Energy Savings | £1,200 | Based on typical usage |
| Added Property Value | £14,000 | Based on £250k home, 5.6% |
| Total 10-Year Return | £26,000+ | Including savings & value added |
| Simple Payback | 6.25 years | Savings alone |
| SEG Income | £120/yr | Export tariff income |
What Maximises the Value Added by Solar?
- Include battery storage: Systems with battery storage command a higher premium than panels alone — buyers value energy independence
- Owned, not leased: Only owned solar systems add value. Leased systems can complicate a sale — Midland Solar only installs owned systems
- Quality panels and inverter: Tier 1 panels with reputable inverters (such as SolarEdge, Solis, Fox ESS) are more valuable to informed buyers
- MCS certification included: All Midland Solar installations come with MCS certification, which is required for SEG payments and proves quality installation
- Keep documentation: Retain your MCS certificate, inverter warranty, panel warranties and installation report — these transfer to a buyer
Frequently asked questions
Do solar panels increase house value in the UK?
Yes, according to multiple studies, solar panels typically increase a UK property value by 4–14%. A 2023 study found that properties with solar panels sold for an average of 4.1% more than comparable properties without them. More recent data suggests this premium has increased as energy prices have risen.
How much value do solar panels add to a house?
The added value depends on the system size, property type, and local energy prices. For a typical 4kW system, you might expect to add £10,000–£20,000 to a property valued at £250,000–£350,000. The premium tends to be higher in areas with higher energy costs and among eco-conscious buyers.
Do buyers pay more for homes with solar panels?
Research consistently shows that buyers are willing to pay a premium for homes with solar panels — particularly those with battery storage included. The key driver is the guaranteed reduction in energy bills, which buyers can see on the Energy Performance Certificate (EPC) and factor into affordability calculations.
Do solar panels improve your EPC rating?
Yes, significantly. A well-sized solar PV system can improve a property EPC rating by one or two bands — for example, from a D to a B. A higher EPC rating is increasingly important for mortgage eligibility and is a formal requirement under some green mortgage products that offer lower interest rates.
Can solar panels make a house harder to sell?
Leased (rent-a-roof) solar panels can occasionally complicate a sale due to the lease agreement passing to the new owner. However, owned solar panel systems (which Midland Solar exclusively installs) are an asset that adds value. We always recommend outright purchase rather than lease arrangements.

What buyers and surveyors actually look at
A solar home’s value is settled less by the panels than by what the buyer’s solicitor, surveyor and lender find when they look closely. Four things carry the weight.
1. The EPC uplift on paper
Solar generation is credited against a home’s calculated energy demand, so a typical 4kWp array is commonly worth somewhere in the region of 5–20 SAP points depending on the starting position — often enough to lift a D to a C, or a C to a B. Buyers see that on the EPC before they see the roof, and a higher band feeds into affordability sums and green-mortgage eligibility. Have the EPC re-assessed after installation; an older certificate gives you no credit for the panels.
2. Owned outright vs leased
The Law Society’s TA6 form asks sellers whether panels are owned outright or whether a lease of the roof or airspace has been granted to a provider. Owned panels are a fixture that simply passes with the house. Rent-a-roof or leased panels are different: the lease (typically 20–25 years) sits on the title and binds the buyer, some lenders will not lend against it or attach conditions, and the conveyancer will want to see the lease and consents. It rarely stops a sale, but it adds friction and narrows the buyer pool.
3. Paperwork as a sale asset
Treat the handover pack as part of the property. The MCS certificate is what the new owner needs to register for Smart Export Guarantee payments; the electrical certificate, DNO notification and panel, inverter and battery warranties show a surveyor the system was installed to standard and is still covered. Every Midland Solar installation is MCS-certified, backed by NICEIC, NAPIT and HIES membership and a 2-year workmanship guarantee — keep it all in one folder for your solicitor.
4. Battery storage and EV-readiness
Buyers increasingly ask not just “does it have solar?” but “can it store it, and can it charge the car?” A home battery (we are a Tesla Powerwall Premium Installer and also fit Fox ESS and Solax) can keep essential circuits running in a power cut when the system is specified with backup (e.g. Tesla Powerwall with its Backup Gateway, or an EPS-enabled Fox ESS or Solax hybrid) — ask for this at survey stage — and lets you charge on cheaper overnight/off-peak tariffs, while a pre-installed EV charger scores well in buyer surveys: in a UK survey of around 1,000 motorists commissioned by charger maker Andersen EV (findings published February 2026), 53% said a pre-installed home EV charger would positively influence their decision if buying a property today — rising to 82% among 18–24-year-olds.
As for the headline number: studies suggest solar adds value and saleability, but figures vary widely — from a low-thousands-of-pounds average uplift in trade-body analyses to premiums of roughly 3–7% in academic studies of Land Registry sales. Treat it as a range, not a promise. To see what a system would do for your home, book a free solar survey and we will design it with resale in mind.
