Selling a House With Owned Solar Panels: FIT, SEG & Paperwork

By Lisa Hayes · 6 November 2026

Yes, you can sell a house with solar panels you own outright, and they will usually help rather than hurt, provided you can prove what they are. The panels pass to the buyer with the house as a fixture. What needs sorting is the paperwork around them: the MCS certificate, any Feed-in Tariff (FIT) registration, your export payments, and any battery or inverter warranties. Get that file ready before you list and the sale rarely stalls on the panels.

Do solar panels go with the house when you sell?

If you bought and paid for them, yes. Panels bolted to the roof, plus the inverter and wiring, are fixtures. They belong to the property in the same way the boiler or the bath does. A buyer will assume they are included, and so will their solicitor.

The grey areas are the bits that sit around the system rather than on it. A home battery in the garage, an EV charger on the wall, a smart monitoring screen. These are usually treated as fixtures too, but "usually" is not a word you want in a contract. The fix is dull and effective: list them on the fixtures and fittings form (the TA10) as included or excluded. If you plan to take the battery to your next home, say so, and say so early. A buyer who finds out at exchange that the battery is leaving will want a price reduction, and they'll have a point.

Our guide on what documents you need to sell a house covers the wider paperwork pile. The solar bits slot into it.

Owned, leased or "free": which type do you actually have?

This is the first question to answer, and I'm amazed how many sellers can't. There are three common setups.

• Owned outright. You paid for the system (or your mortgage or a green loan did). You own the kit. This guide is for you.
• Leased or rent-a-roof. A company installed panels and pays you a small sum, or you get free electricity, in return for use of your roof, typically under a long lease. You don't own the panels. Lenders have strict rules about these leases, and the UK Finance (formerly CML) guidance for lenders says a buyer's lender can ask for the lease to be varied or can decline to lend on the property.
• Bought on finance. You own the panels but a loan is attached, which may be secured against the house or may not. Check the loan terms and the settlement figure, because the lender will want repaying on completion if the debt is secured. See our guide to mortgage redemption statements for the principle.

Find your installation contract. If the word "lease", "licence", "roof space" or "power purchase agreement" appears, stop and take advice before you do anything else.

What is the Feed-in Tariff, and does it matter when I sell?

The Feed-in Tariff was the government scheme that paid households for the electricity their panels generated, whether or not they used it. It matters hugely if you have it, because it can be a real income stream the buyer is inheriting.

The facts, from Ofgem's own pages. The scheme closed to new applications from 1 April 2019, but installations already accredited carry on. Support is typically payable for 20 years from accreditation, though Ofgem says the period can run between 10 and 25 years depending on technology, capacity and commissioning date. Payment rates are adjusted every year. Up to FIT Year 16 they followed RPI, and from FIT Year 17 they follow CPI.

So a system commissioned in 2012 on a 20-year tariff is still being paid into the early 2030s. That's not a footnote. For a buyer, a decade of index-linked generation payments is a genuine part of what the house offers.

• 1 April 2019FIT closed to new applications
• ~20 yearstypical FIT payment period
• 10–25possible range of years, per Ofgem
• CPIindexation from FIT Year 17

How do you transfer the Feed-in Tariff to the new owner?

Ofgem splits this into two routes, and the right one depends on the size of your system.

Most homes are "MCS-FIT": solar PV at or below 50kW. For these, Ofgem's advice to someone moving into a house with panels is to contact the FIT licensee the installation is registered with, who then updates the generator's details on the Central FIT Register. In practice, the licensee is the energy supplier that has been paying you the generation tariff. The sensible move as a seller is to phone them once your sale is agreed, tell them the expected completion date, and ask exactly what they need from you and from the buyer.

Larger systems are "ROO-FIT" (above 50kW, which is rare on a house but common on farms and larger commercial roofs). Here the owner first updates the entry on the Renewable Electricity Register by emailing Ofgem, who send a transfer request form; the completed form goes back with supporting documents, and the new owner then notifies the FIT licensee.

What Ofgem's page does not spell out is who keeps the money for the quarter in which you sell. That's a matter for your contract. My view: agree it in writing. Take a final meter reading on completion day, send it to the licensee, and tell your solicitor the reading so the sale paperwork can say who is entitled to what. It costs ten minutes and avoids a squabble over a few hundred pounds that nobody enjoys.

And one warning on delay. If the licensee doesn't process the change of ownership, Ofgem says to complain to the licensee first and go to the Energy Ombudsman after eight weeks. Better to start the process early than to need that route.

What is the Smart Export Guarantee, and does it move with the house?

The Smart Export Guarantee (SEG) is the scheme that replaced FIT for new installations. It pays you for surplus electricity you send back to the grid. It started on 1 January 2020 and, per GOV.UK, the SEG licensee must always pay a rate above zero.

It isn't tied to a fixed 20-year term the way FIT is. It's a contract with a supplier, and the buyer can sign up with whichever licensee they prefer. To qualify, Ofgem says the installation and installer must be certified under MCS (or an accepted equivalent), and you need a meter capable of half-hourly export readings, which is typically a smart meter.

The point for sellers: SEG and FIT exports don't mix. Ofgem says you cannot receive SEG payments while receiving FIT export payments. If you're on FIT, the buyer inherits that arrangement. If you're on SEG, you close your agreement when you leave and the buyer starts their own. Either way, hand over the MCS certificate, because it's the buyer's key to registering for SEG.

Which documents does a buyer's solicitor ask for?

I'll be blunt: this is where owned-solar sales go wrong. Not because anything is amiss, but because the seller can't find the paperwork from 2011. Put this folder together before you list.

1. MCS certificate. Proof that the installer and installation were certified. Needed for SEG, and a lender may ask for it.
2. Building regulations or competent-person scheme certificate. Installers normally self-certify. Without it, the buyer's solicitor may raise it as a defect. Our piece on indemnity insurance when selling explains the usual fallback if it genuinely can't be found.
3. Electrical installation certificate for the PV circuit and inverter.
4. The FIT paperwork: your statement of FIT terms, the licensee's name, and the last meter readings you were paid for.
5. Warranties and guarantees for panels, inverter and any battery, plus the installer's workmanship guarantee and any roof-penetration guarantee.
6. Monitoring app login details to be handed over at completion, with your own account removed.
7. An EPC that reflects the system, which is also relevant to the FIT band. Ofgem says the higher solar tariff band needed an EPC rated D or above issued before commissioning.
8. Roof details: any structural report, scaffold-and-fixing paperwork, and photos of the installation.

The standard property information form, the TA6, asks about energy installations and anything attached to the property. Answer it accurately. If a system is leased or has a financing agreement, saying otherwise is misrepresentation, and that's a fight you'll lose.

Do solar panels add value to a house?

They can, and you'll see all sorts of percentage claims online. I'm not going to repeat a figure I can't source to a primary document, and neither should you in your listing. Treat any "adds X%" claim sceptically.

What I can say with confidence is how buyers and valuers think. A buyer values the panels for what they save and earn, which depends on the age and condition of the system, the size, the orientation of the roof, whether there's a battery, and whether FIT income remains. A ten-year-old system with a clean paper trail, a working inverter and years of FIT payments left is a selling point. A tired system with no certificates and an inverter nearing end of life is a question mark.

My recommendation is to sell the numbers, not the adjective. Put your last twelve months of generation readings in the information pack. Show the quarterly FIT statements. If you have a battery, show the savings. Buyers pay for evidence. For the bigger picture on what lifts a sale price, our guide to what adds the most value to a house puts solar in context.

Is it better to sell with panels, or take them off first?

Almost always keep them on. Removal means scaffolding, a roofer, reinstatement of tiles, and a roof that looks tired, and you'd typically be taking down kit that is earning FIT income for someone. The only sensible exceptions are a system so old that it's now a liability, or a deliberate decision to move panels to your next home, which needs an installer, new MCS certification, and in most cases a fresh grid connection application. For FIT systems, taking the panels away can also put the tariff itself at risk. Speak to your licensee before making any decision.

What if the panels have no paperwork?

It happens more than you'd think, particularly with systems fitted in the early FIT years by installers who've since folded. You have options, in rough order of effort.

Start with the obvious: your FIT licensee often holds the MCS certificate number, because they needed it to register you. Then try the MCS database, which lists certificated installations. Then your old installer or the scheme body they belonged to. If the building regulations certificate is the gap, a local authority building control officer may be able to confirm what's on file. And as a last step, a buyer's solicitor may accept indemnity insurance for a missing certificate, as covered in our indemnity insurance guide, although that is a lender decision rather than a right, and it won't fix a genuinely unsafe installation.

Do not guess at a certificate or let anyone "tidy up" documents. A fudged paper trail is worse than a missing one.

Will a buyer's mortgage lender have a problem with solar panels?

For owned panels, rarely. Lenders worry about leases over the roof, not about kit you own. The UK Finance guidance on roof leases (England and Wales) says most lenders' mortgage conditions require consent to any lease, and that without it a lender may not be bound by the lease at all. A buyer's lender reviewing an existing lease can ask for variations or choose not to lend.

That's why the first thing to establish is ownership. If you own, say so and prove it. If you lease, you may find a large share of mortgage lenders turn the buyer away, and your realistic buyer pool shrinks to cash purchasers. In that case, a cash house buyer can be a legitimate route, though you should compare what is on offer, not just accept the first number. Our comparison of house buying companies shows how to do that sensibly.

What happens if the system is on a roof you're about to re-roof, or is faulty?

Two common edge cases, both manageable.

If the survey says the roof needs work, panels complicate things because they have to come off and go back. Get quotes before listing so you can negotiate on facts. See what happens if a survey finds problems.

If the panels aren't working, say so. Selling a house "as is" is perfectly legal if you disclose; hiding a fault is not. Our guide to selling as is sets out how to do it properly.

What about a battery, an EV charger or a heat pump alongside the panels?

These stack up. Batteries change how the system is treated for FIT: Ofgem says the licensee must be told about battery storage, along with capacity changes, meter replacements and other modifications. If you added a battery after the original FIT registration and never told them, fix that before you sell, not during.

Heat pumps, which often partner with solar, bring their own paperwork; see our guide to selling a house with a heat pump. And an EV charger is worth a line in the fixtures list.

How do you market a house with solar panels?

Specific beats vague. "Solar panels" in a listing means nothing. This means something: "4kW system installed 2013, FIT-registered, generation statements available, inverter replaced 2021, MCS certificate on file." Say that in the first paragraph.

For online listings, estate agents have obligations around material information, which includes energy-related details; our material information guide explains what has to appear. Be ready to give the agent the facts, so their listing is accurate rather than aspirational.

If you want a sense of what you'd get on the open market, start with a free house valuation, and see how much your house is worth for how valuers actually reach a figure.

Can you sell quickly if the panels are causing problems?

If the issue is a lease or missing certificates that a mainstream buyer's lender won't accept, speed becomes a real concern. A cash buyer doesn't depend on a mortgage lender's view of the lease, which is why some sellers in this position go that route. Be realistic about the trade-off: cash buyers price in the problem, so offers sit below market value. Read our guide on selling a house fast and the below-market-value explainer before you decide, and always compare more than one offer.

If you simply want a smooth conventional sale, the best thing is preparation. Our guide on getting your house ready to sell and the one on speeding up a house sale both help.

What will the buyer's surveyor look at on the roof?

A standard homebuyer report will note that panels are present and may comment on the roof covering beneath them, which the surveyor often can't see. Expect the surveyor to recommend that the buyer asks for the electrical certificate and any structural sign-off, and to flag the inverter's age. None of that is a disaster. It is a prompt for questions you can answer in advance.

The practical lesson is that a survey which "can't inspect" the roof under the panels pushes risk back onto the seller in negotiation. If your roof was in good order when the panels went on, say so, and offer the installer's roof assessment if you have one. If you have never had the roof checked since installation, a quick inspection by a roofer before you list is cheap peace of mind and gives you something concrete to show. For the wider question of whether to commission your own survey first, see our guide to the pre-sale survey.

Does it differ in Scotland, Wales or Northern Ireland?

The FIT and SEG schemes cover Great Britain, so England, Scotland and Wales work the same way for the generation and export payments. Northern Ireland had its own arrangements, so if that is where you live, ask the relevant supplier what applies. The conveyancing differs too: in Scotland the sale runs through a different legal process, covered in our guide to selling a house in Scotland. Also note that the UK Finance lease guidance mentioned above applies to England and Wales only.

A seller's checklist for a house with owned solar panels

The mistakes I see sellers make

Four come up repeatedly. First, assuming "free" panels are owned. They often aren't. Second, not telling the FIT licensee and carrying on receiving payments you're no longer entitled to. Third, claiming a price premium without evidence. A buyer's valuer will not take your word for it. Fourth, leaving documents until after the offer. Once the buyer's solicitor asks and you can't produce anything, you're back-footed in a negotiation you could have controlled.

So, should you worry?

If your panels are owned and you've got the paperwork, no. They are an asset and you should say so. If they're leased or the paperwork is thin, deal with it now, because it's far cheaper to solve before a buyer finds it. Whichever situation you're in, ask for more than one opinion on price, and if you want to see what a fast cash route would look like alongside a normal sale, compare offers through Ready Steady Sell. It costs nothing, and you can walk away.
