Do solar panels add value to your home in the UK? The short answer is yes — but how much depends on the type of system you have, your EPC rating, where you live, and whether the panels are owned outright or leased. Research suggests UK properties with owned solar panels sell for 4–14% more than comparable homes without them, but the picture is nuanced. This post walks through the evidence, the EPC impact, what estate agents and buyers actually think, and the conveyancing complications that leased systems create.
Several studies have examined the relationship between solar panels and property values in the UK. The findings consistently show a positive premium, though the range is wide.
The 4–14% uplift figure reflects a range of property types, locations, and system sizes. Larger systems on detached homes in areas with higher energy costs tend to attract greater premiums. Properties in cities with active green buyer demographics — London, Bristol, Brighton — often see the higher end of that range. Rural and northern properties see more modest uplifts, though the EPC benefit still applies.
The Energy Performance Certificate (EPC) is the most direct and measurable way solar panels affect property value. Solar panels generate on-site renewable electricity, which the EPC methodology credits against your home’s estimated energy use. A typical 3.5–4 kWp system on a semi-detached house can move an EPC rating from D to C, or in some cases from D to B.
This matters for several reasons:
It is worth getting an updated EPC after installation if yours is more than two years old. The updated certificate will reflect the panels on the property and provide documentation that buyers and lenders can reference.
Estate agents’ treatment of solar panels has shifted significantly over the past five years. Where solar was once seen as a quirky feature, many agents now actively market it as a premium — particularly in the context of energy price rises since 2021.
The most effective ways to present your solar system to an agent include:
Which? research on solar panels and home value found that buyers are increasingly seeking out solar-equipped homes, particularly when energy bills are high — and that documented savings data is the most persuasive factor in securing a premium.
The property value benefit described above applies to owned solar panels — systems you purchased outright or financed with a loan, where you own the equipment and receive both the energy savings and any SEG payments.
Leased solar panels are a different matter entirely. Schemes common in the early 2010s — often marketed as “free solar panels” — involved a third-party company installing panels on your roof and retaining ownership. The company kept the Feed-in Tariff generation payments, and you received discounted or free electricity during daylight hours. Some arrangements involved a 25-year lease agreement on your roof space.
These lease arrangements can cause serious complications when selling:
If you have leased panels and are planning to sell, contact the lease company as early as possible to understand your options. Some companies will buy out the lease for a lump sum. Others will transfer the lease to the new owner — which is possible but requires the buyer’s agreement and their lender’s acceptance.
Based on estate agent feedback and buyer surveys, the features that make solar panels most attractive to buyers are:
Removing solar panels before selling is almost never advisable. The removal cost alone — typically £500–£1,500 for a standard residential array — would erode any value gained by removing the system. And there is no evidence that buyers discount properties because of solar panels; quite the opposite.
The only scenario where removal might be considered is if the panels are in poor condition, mounted on a flat roof in a way that damages the waterproofing, or part of a problematic lease arrangement that cannot be transferred. In those cases, the cost of remedying the issue (repair or lease buyout) should be weighed against the alternative of removal and the loss of any premium.
For the vast majority of sellers, the right approach is to present the solar system as an asset: gather the documentation, get an updated EPC, quantify the savings, and let the panels support — not hinder — the sale.
