Do solar panels add value to a house?

That is the short version. The rest of this is about why, and what you will actually be asked for.

What the EPC says, and why it matters more than the panels themselves

Every home sold in England and Wales needs a valid Energy Performance Certificate, and it has to be available from the point the property is marketed. An EPC lasts ten years and rates a home from A (most efficient) to G (least efficient), based on the fixed fabric and the systems installed, not on how you use the house day to day. That is government guidance, not ours.

Solar PV is one of the measures that improves that calculation, because the assessment counts the electricity the panels generate against the home's modelled energy use and carbon emissions. It will not turn a solid-wall Victorian terrace into an A-rated home on its own. On a reasonably well-insulated semi or detached house it can move the banding, sometimes by more than one letter, depending on what else is already in place (loft and cavity insulation, the heating system, double glazing).

The EPC is the one energy document every seller has to produce and every mortgage lender's valuer will see, which is why buyers increasingly look at the band before they look at anything else on the listing. A better band does not guarantee a higher sale price. It does mean one less question for a cautious buyer to ask.

Is there a price premium for solar panels specifically?

Several estate agents and portals have talked about buyer interest in "green" homes rising, and that is plausible given energy bills are the thing most people now ask about on a viewing. But we have not found an independent, replicated UK study that isolates solar panels and puts a reliable percentage or pound figure on the uplift, separate from the EPC band, the general condition of the roof, or the area. Anyone quoting you a specific percentage is usually extrapolating from a single survey of estate agents' opinions, not from actual sold prices.

So the honest position is: owned panels in good condition are very unlikely to put buyers off, and a better EPC band is a genuine, documented advantage at sale. A specific value uplift in pounds is not something we can back with evidence, and we will not invent one.

Owned panels versus leased panels: this is where sales actually get complicated

This is the distinction that matters far more than whether panels exist at all.

Owned outright. You paid for the system (or it is fully paid off if you financed it), you hold the paperwork, and the panels are yours to keep or remove like any other fixture. This is how Pro-Fit's installations work: there is no lease, no rent-a-roof arrangement, and no third party with a claim on your roof.

Leased or "rent-a-roof". A company owns the panels, uses your roof under a long-term agreement, and keeps some or all of the income the panels generate. You get free or discounted electricity in exchange. The old Feed-in Tariff made these schemes commercially attractive to installers while it was open to new applicants.

A leased system is the scenario that causes delays. The buyer's solicitor has to establish whether the lease (sometimes registered as a formal lease of the airspace above the roof) transfers automatically to the new owner, whether the buyer's mortgage lender is comfortable lending against a property with a third party's equipment attached to it, and what happens to the income if the buyer does not want to keep making the arrangement work for someone else's benefit. Some buyers walk away rather than deal with it. MoneySavingExpert's guidance on solar schemes makes a related point about a different model, the newer "subscription" plans where you own the panels from the outset: selling a property partway through a long-term subscription agreement "may not always be straightforward" either, even though you hold title to the equipment.

If you are not sure which category your panels fall into, check whether you, or a previous owner, ever signed anything described as a lease, or whether you made any upfront payment at all. If you paid for the system in full, you own it.

The paperwork a buyer will ask for

The Law Society's TA6 Property Information Form is what every seller in England and Wales fills in, and it asks directly whether any solar panels at the property are owned outright or leased. Get that wrong, even unintentionally, and you risk a dispute after completion, because the form is a legal representation the buyer relies on.

In practice, a buyer's solicitor (and often their lender's surveyor) will want to see:

• Proof of ownership, or the original contract if the system is leased.
• Building regulations compliance, or the structural report if the roof needed reinforcing.
• Electrical certification for the installation (the handover documentation that came with the system).
• Any manufacturer warranties for the panels, inverter and battery, so the buyer knows what transfers and what does not.
• Details of any Feed-in Tariff or Smart Export Guarantee arrangement, since FiT (closed to new applicants from 1 April 2019) can in principle continue for existing installations, while the Smart Export Guarantee is run through whichever licensed supplier the seller signed up with.

None of this is unusual or a sign of a problem. It is the same kind of file a buyer's solicitor would want for a new boiler, a replaced roof, or a loft conversion. It takes minutes to produce if you kept the paperwork, and can take weeks to chase down if you did not.

A straight opinion: deal with the roof first

If a roof has perhaps ten years of useful life left, our view is that it should be addressed before panels go up, not after. Removing and refitting panels to repair or replace a roof later costs more than doing the work in the right order, and a buyer's surveyor will ask about roof condition regardless of what sits on it. This is not a sales line. It is the same advice we would give a friend.
