Solar panels add value to UK homes. The evidence has strengthened considerably as energy costs have risen and buyers have become more energy-literate. A home with a working solar PV system and a strong EPC rating typically sells faster and at a premium compared to an equivalent property without panels.

The uplift varies, though. It depends on whether panels are owned outright or leased, the system’s age and condition, the property’s EPC rating, and local buyer demand. Owned panels typically add 1 to 4% to property value. Leased panels under old rent-a-roof schemes can actually complicate a sale.

This guide explains exactly how solar panels affect UK house prices, what buyers and surveyors look for, and how to present your installation to maximise its contribution to your asking price.

Key Takeaways

  • Solar panels typically increase UK property values by 1–4%, equivalent to £3,000–£15,000 on an average home.
  • The effect is strongest when panels are owned outright, rather than leased through a rent-a-roof scheme.
  • Improving your home’s EPC rating, which solar panels reliably do, directly affects mortgage eligibility, stamp duty considerations, and buyer perception.
  • Homes with an EPC rating of C or above sell faster and command a premium over similar homes rated D or below.
  • Leased solar panels can complicate property sales and may reduce value if buyers are unfamiliar with the lease terms.

Do Solar Panels Add Value to a House in the UK?

The evidence is clear: solar panels add value to UK properties. The question is how much, and the answer depends on whether the panels are owned or leased, the home’s location, its current EPC rating, and how the wider property market is performing.

Research from the Department of Energy and Climate Change (now DESNZ) and various UK estate agents consistently points to a 1–4% uplift in property value for homes with owned solar panels. On the average UK house price of around £285,000, that’s a potential value increase of £2,850 to £11,400.

Some studies suggest the uplift can be higher in areas with stronger environmental awareness and higher energy costs, parts of London and the South East, for example, where buyers place a premium on low running costs.

For context, the average solar panel installation in 2026 costs around £8,000–£11,000 for a 4–5kWp system after 0% VAT. If that installation also increases your property’s value by £5,000–£8,000, the combined financial return from energy savings and capital appreciation makes the investment even more compelling.

Why Solar Panels Increase Property Value

EPC Rating Improvement

The most direct mechanism by which solar panels increase property value is through the Energy Performance Certificate (EPC) rating. Solar panels reliably push homes up the EPC scale, often from D to C, or from C to B.

This matters enormously in the current UK property market. From 2025, most lenders are beginning to offer green mortgage products with preferential rates for homes rated EPC C or above. A higher EPC rating can mean lower mortgage costs for buyers, which translates directly into willingness to pay more for the property.

Beyond mortgages, the government’s net-zero trajectory means properties with poor EPC ratings face increasing scrutiny, there’s a growing expectation that landlords and sellers will eventually need to meet minimum EPC standards. Buyers who understand this dynamic will pay a premium today to avoid retrofit costs tomorrow.

Lower Running Costs

A 4kWp solar system in the UK generates around 3,400 kWh per year. At current electricity prices, that translates to roughly £700–£900 per year in savings on energy bills. Buyers can quantify this benefit directly, and estate agents increasingly mention solar generation figures in property listings.

When a buyer is comparing two otherwise identical homes, one with solar panels saving £800/year and one without, the solar home is objectively more valuable. The buyer’s willingness to pay more is rational, not just sentiment.

Environmental Credentials

A growing proportion of UK homebuyers actively seek out low-carbon properties. YouGov research has found that a majority of UK adults consider a home’s environmental impact when purchasing. Solar panels are a visible, tangible signal of those credentials.

This demographic trend is strengthening. Younger buyers, who are now a significant segment of the UK property market, are more likely to value environmental features than previous generations.

How Much Do Solar Panels Add to House Value?

The research on this is more nuanced than headline figures suggest. Here’s what the evidence shows:

Nationwide Building Society research found that a home with an EPC rating of C (which solar panels help achieve) sells for an average of £14,000 more than an equivalent home rated D. Solar panels are not the only route to a C rating, but they are one of the most reliable.

A study by Halifax found that green home improvements, including solar panels, add an average of 1.7% to a property’s value. On a £285,000 home, that’s around £4,800.

Rightmove data suggests that homes marketed with solar panels attract more buyer enquiries and sell more quickly, particularly relevant if you’re looking to achieve a fast sale.

It’s worth noting that the uplift is location-dependent. In high-value areas (London, South East, parts of the South West), the premium can be higher in absolute terms. In lower-value areas, the percentage uplift may be similar but the absolute figure smaller.

Owned vs Leased Solar Panels: How It Affects Your Sale

This is a crucial distinction. Owned solar panels almost always add value. Leased panels can complicate sales significantly.

The rent-a-roof schemes that were popular in the UK between 2010 and 2015, where a solar company installed panels for free in exchange for keeping the Feed-in Tariff income, created a complicated situation for homeowners. The lease (typically 25 years) transfers with the property. Buyers must accept the lease terms, and some mortgage lenders will not lend on properties with certain types of solar lease.

If you’re selling a home with leased panels, you’ll need to:

  • Disclose the lease to buyers and their solicitors
  • Confirm that your buyer’s mortgage lender accepts properties with solar leases
  • Potentially arrange to buy out the lease before sale if it’s causing problems

Since 2016, the Feed-in Tariff closed to new applicants and the rent-a-roof model largely disappeared. If your solar panels were installed after 2016, they are almost certainly owned outright, check your original installation contract if you’re unsure.

For panels installed post-2016 and owned outright, there’s no complication. The panels, the roof warranties, and any Smart Export Guarantee agreements all transfer to the buyer as an asset.

Preparing to Sell a Home With Solar Panels

If you’re selling a property with solar panels, there are several steps worth taking to maximise the value they add:

Get an up-to-date EPC. Your current EPC should already reflect the solar installation, but if it’s more than two years old, consider commissioning a new one. A higher EPC rating on paper is a marketing asset.

Gather your documentation. Buyers will want to see: the installation certificate (MCS), the inverter warranty (typically 10 years), the panel warranty (typically 25 years), any SEG agreement, and records of generation if available. Having these in order speeds up the conveyancing process and reassures buyers.

Speak to your estate agent about positioning. Not all estate agents know how to market solar panels effectively. Providing them with the annual generation figure, the estimated bill saving, and the remaining warranty periods gives them tangible selling points.

If panels are leased, consider buyout. If you have an old rent-a-roof lease, contact the solar company to understand buyout terms. Buying out the lease may cost a few thousand pounds but can remove a significant barrier to sale and mortgage approval.

Solar panels installed on a UK home

Case Study: A Homeowner in Surrey Prepares to Sell

Background

A homeowner in Guildford, Surrey, purchased a three-bedroom semi-detached house in 2018 and installed a 4kWp solar system the following year at a cost of £6,500. The installation pushed the home’s EPC rating from D to C.

Project Overview

When the homeowner came to sell in early 2026, they worked with their estate agent to market the property’s solar panels as a key feature. The listing highlighted the annual generation figure (3,200 kWh), the estimated annual saving (£850), and the remaining 22-year panel warranty.

Implementation

The homeowner gathered all documentation, the MCS certificate, inverter warranty, and SEG agreement with Octopus Energy, and provided these to their solicitor at the outset to streamline conveyancing.

Results

The property sold for £387,000. The estate agent estimated that comparable properties on the same street without solar panels had sold in the range of £372,000–£378,000 in the preceding six months. The premium attributable to the solar installation was estimated at approximately £9,000–£15,000, well above the original installation cost.

Expert Insights From Our Solar Panel Installers About Property Value

One of our senior solar panel installers with over fifteen years of experience in the UK market shares this observation:

“We’ve seen a real shift in buyer attitudes over the past three years. When I started out, solar panels were something buyers didn’t really know how to value, some saw them as a bonus, others were uncertain. Now, buyers actively ask about them. They want to know the system size, the generation figures, and whether there’s a battery. Properties with solar sell faster. That’s become a consistent pattern we hear from agents we work with.”

Frequently Asked Questions

Do solar panels increase house value in the UK?

Yes. Research suggests solar panels increase UK property values by 1–4% on average. The uplift is strongest for owned panels (not leased) and is closely linked to the improvement in EPC rating that solar panels typically deliver.

How much do solar panels add to the value of a house?

Based on UK research, solar panels add between £3,000 and £15,000 to a property’s value depending on the home’s value, location, system size, and current EPC rating. Halifax research found an average uplift of around 1.7% for green home improvements including solar.

Do leased solar panels affect house sales?

Yes, leased solar panels can complicate sales. The lease transfers with the property, and some mortgage lenders won’t lend on homes with certain lease types. If you have old rent-a-roof panels (typically installed 2010–2015), speak to a solicitor before listing your property. Panels installed after 2016 are almost always owned outright.

Do solar panels improve EPC rating?

Yes. Solar panels are one of the most reliable ways to improve an EPC rating. A 4kWp system will typically push a home up by one EPC band, for example from D to C. This is significant because EPC C or above unlocks better green mortgage rates and makes the property more attractive to buyers.

Do solar panels make a house harder to sell?

No, owned solar panels generally make a house easier to sell, not harder. They attract more buyer enquiries and Rightmove data suggests they can reduce time on market. The only scenario where solar panels complicate a sale is when they are subject to an old rent-a-roof lease rather than owned outright.

Do I need to declare solar panels when selling my house?

Yes. Solar panels must be disclosed in the property information form (TA6) and any lease arrangements must be disclosed to buyers’ solicitors. You should also have the MCS certificate and warranties available for the conveyancing pack.

Do solar panels affect buildings insurance when selling?

Solar panels should be declared on buildings insurance. For buyers, this means checking that the panel system will be covered under the new policy. Most standard home insurance policies can cover solar panels, though you may need to declare the added value, typically £8,000–£12,000 for a standard system.

Are solar panels worth installing before selling a house?

Potentially yes, but the timing matters. If you plan to sell within 1–2 years, the property value uplift may justify installation costs, particularly if it pushes the home from EPC D to C. However, the full financial benefit of solar (energy bill savings) is best realised over 7–12 years. Installing purely to sell shortly after is a smaller financial win than installing to live with the system for several years.
