Do Solar Panels Add Value to Your Home in Scotland? What If You Move?

Some of our older customers have told us that a payback of a decade or more feels too long, or that they may have moved by then. The payback figure counts only what the panels save on your bills and earn from export. It doesn't say whether they add anything to the price when you sell. On that, the research is mixed: UK studies range from close to nothing to a few per cent, and none of them uses Scottish sale prices.

Figures checked 10 November 2026.

What payback counts, and what it leaves out

Payback is the installed cost divided by what the system brings in each year: the electricity you no longer buy, plus what you're paid for the electricity you export. The Energy Saving Trust (EST) puts it at 11 to 12 years for a typical system in Stirling, the longest of the places it models. Our own worked example at October 2026 prices comes to 11.0 years, or 13.9 years on a 4.1p export rate. Our solar payback guide shows the sums and has a calculator for your own figures.

That number reads differently at 70 than at 40. EST expects panels to last 25 years or more, so a younger household can expect many years past the break-even point. If you might move in five years, you won't get there on bill savings alone, and our payback guide says so too: solar is less likely to be worth it if you expect to move in the next few years.

The payback sum has nothing to say about whether the next owner pays anything for the panels, and nobody can promise that for your house.

What the research says about solar and house prices

Some studies look at what happens to prices when a home's EPC rating improves, for any reason. Others look at homes with solar panels specifically.

Studies that found a premium

Rightmove's Greener Homes Report (July 2023) looked at 300,000 homes that sold twice in the previous 15 years, with a new EPC issued between the two sales. After removing local house price growth and allowing for floor area, homes that went from D to C carried a 3% price premium on average. That was £11,157 at the national average asking price of the time. Rightmove describes it as a correlation. The upgrades behind it include things like new windows, which also improve a home's condition, and solar isn't separated out. There's no regional breakdown, so there's no Scottish figure. An earlier Rightmove study in 2021, of over 200,000 homes, had put the D to C figure at 4%.

Knight Frank (October 2022) also found 3% for D to C, above local price growth.

A 2024 study by researchers at Swansea and Birmingham, published in Energy Economics, measured solar directly. Using Zoopla data on UK homes, it found that homes with solar panels were associated with prices 6.1% to 7.1% higher. One of the authors' checks gave a lower 3.5%, and they found the premium has been declining over time. The paper's abstract doesn't say whether these are asking or achieved prices, and Scotland isn't reported separately. This is a different measure from Rightmove's, so the two figures shouldn't be read as one range.

Studies that found little effect

Nationwide's analysis published in June 2026 is the most recent. It used Nationwide's own mortgage lending for house purchases in England during 2025, and compared similar homes. For owner-occupiers, A and B rated homes carried a "modest premium of 1.6%" over a similar D rated home. It found "little difference for properties rated C or E, compared with D".

A study for the trade body Solar Energy UK, written up in the RICS Property Journal in January 2022 with Franz Fuerst of the University of Cambridge, matched 5.7 million Land Registry sales against MCS and EPC records. It found a solar premium of 0.9% to 2%. Land Registry covers England and Wales.

These are averages across very large numbers of homes, mostly in England. They are correlations, so none of them proves the panels caused the difference, and none can tell you what a buyer will pay for your house.

What about Scotland?

We couldn't find any study of Scottish sale prices and solar, or anything published by Registers of Scotland on it.

What there is comes from a Nationwide survey of 1,000 Scottish homeowners carried out in May and June 2026. 82% said they expect buyers to pay more for an energy-efficient home, and 70% said EPC ratings or energy efficiency matter more now than when they bought. That measures what owners expect, not what buyers have paid. The same release quotes the Scottish House Condition Survey: nearly 180,000 Scottish homes, about 8%, already have solar panels, so buyers and surveyors here will have seen them before.

When you sell in Scotland, the Home Report includes the Energy Report, which is your EPC, so buyers see the rating from the start. The Scottish Government's new style of EPC has been put back to 30 April 2028 (gov.scot update, 24 August 2026), so a home sold now still carries a current-style EPC.

How solar shows up on your EPC

Scottish EPCs for existing homes have been produced with a method called RdSAP 10 since June 2025. It counts solar panels, batteries and diverters, so adding solar can raise your EPC score.

How far it moves the score depends on the house: where the score starts, the size of the system, which way the roof faces, shading, whether there's a battery, and how close the home already sits to a band boundary. A band is around 11 to 15 points wide (C runs from 69 to 80, B from 81 to 91). A home just below a boundary may move up a band, and one in the middle of a band may stay where it is. Even Barclays, which rewards solar installs, says there's "no guarantee" an improvement will raise your rating.

Your own EPC is the best guide. It lists recommended improvements and the rating each could reach, so if solar panels are on that list you can see the likely effect for your house. You can find your certificate on the Scottish EPC Register.

Green mortgages and lender cashback

This is what four lenders' own pages said on 10 November 2026. Terms change, so check with the lender before relying on any of it.

Most of this helps one of two groups: people who already have a mortgage with the lender and are installing solar, or buyers of homes rated A or high B. Those ratings are uncommon in older Scottish homes: around 77% of those built before 1919 are rated D to G. Nationwide and Lloyds also refer to the government's EPC register, and Scottish certificates sit on a separate register, so ask the lender whether a Scottish EPC qualifies.

If you sell: what the buyer will ask for

The Energy Saving Trust's advice on buying a house with solar (February 2025) tells buyers what to check. It's worth having these ready:

• the MCS certificate for the installation
• the system size, and details of any battery
• the inverter's age (EST says it generally needs replacing after around 12 years)
• details of any export tariff or Feed-in Tariff, and a change of ownership form for it
• confirmation that the system is included in the sale, for example on the fixtures and fittings list

Export payments don't transfer with the house. The Smart Export Guarantee (SEG) is a contract between you and your supplier, so the buyer applies for their own. To join Octopus's SEG tariff, for example, the installation must be certified under MCS (or the FlexiOrb scheme), and there must be a half-hourly export meter. Without the MCS certificate, the next owner may not be able to get paid for exports, so keep it safe. Older systems on the Feed-in Tariff need a change of ownership with the FIT supplier, and the buyer can then claim the remaining payments.

A buyer is likely to want the warranty documents for the panels, inverter, battery and workmanship as well. Our warranty and aftercare page explains which warranties come with an installation.

Leased "rent-a-roof" systems are a different matter. The UK Finance Lenders' Handbook sets out lenders' requirements for roof leases in England and Wales, but says "At present there is no guidance for Scotland." If your panels are leased, speak to your solicitor and expect the buyer's lender to ask questions. Panels you own outright, with an MCS certificate, avoid that problem.

Solar is also turning up more often in listings. Rightmove saw almost 40% more mentions of solar panels in property descriptions of homes for sale in 2025 than in the same period a year earlier. That may make a home more appealing to some buyers. We haven't found UK evidence that homes with solar sell any faster.

Export income while you're still there

Whatever happens when you sell, the panels earn something every year you're in the house. Export rates on Octopus's own pages, checked 10 November 2026:

• 12p per kWh on Outgoing Octopus, a variable rate that needs Octopus as your electricity supplier
• 4.1p per kWh on the Octopus SEG tariff, a flat rate open to people who stay with another supplier

Octopus also has Prime Outgoing and Agile Outgoing, which pay different rates at different times of day. If you're out during the day or use little electricity, more of your solar gets exported. Exported units earn less than the units you use yourself would save, so the export rate you pick matters more for you. A battery can export at peak times on some tariffs, but how much that's worth depends on the tariff and how it's set up. Our guide to selling solar back to the grid covers how to apply.

When waiting is the right call

Waiting is a sensible decision if:

• your roof needs replacing soon
• the roof is heavily shaded or faces north
• you're likely to sell within a year or two
• you'd rather keep the money available

The sums can be redone later if things change.
