Moving House with Solar Panels: What Happens?

If you're selling a home with solar panels or buying one, there are practical and legal considerations. The good news: it's straightforward in most cases. The bad news: leased or rented panels can complicate things.

Panels You Own Outright

If you purchased your solar system outright (or finished paying off finance), the panels are a fixture of the property — like a kitchen or bathroom. They transfer automatically with the sale.

What the Seller Should Do

Before marketing:

• Gather all solar documentation (MCS certificate, warranties, installation details)
• Ensure the system is working properly and well-maintained
• Get an updated EPC showing the solar installation
• Check your generation meter reading

During the sale:

• Include solar panels in the property listing (it's a selling point)
• Provide the buyer with all documentation
• Notify your SEG supplier that you're moving (they'll close your account)
• Transfer monitoring account credentials (GivEnergy app, Solis Cloud, etc.)

At completion:

• Hand over: MCS certificate, inverter manual, warranty documents, generation meter reading
• Provide installer contact details for future maintenance
• Cancel your SEG registration

What the Buyer Should Do

• Request all solar documentation from the seller
• Register for SEG with your chosen supplier (see our SEG guide)
• Register the system with the manufacturer for warranty coverage
• Set up monitoring (inverter app/portal)
• Inform your home insurer about the solar panels
• Take a generation meter reading on completion day

Feed-in Tariff Systems

If the property has a system registered under the Feed-in Tariff (FiT), this is a significant financial asset. FiT payments are inflation-linked and continue for 20–25 years from the original installation.

How FiT Transfers

1. The seller notifies their FiT licensee (energy supplier) of the property sale
2. The FiT licensee transfers the FiT registration to the new owner
3. The buyer needs to provide their details and meter readings
4. FiT payments continue to the new owner at the same rate

FiT Value

FiT rates depend on the installation date. Systems installed during the generous early years (2010–2012) can have generation tariffs of 40–45p/kWh — worth £1,500–£2,000/year. This is a valuable asset that should be reflected in the property price.

Leased or Rented Panels

If the solar panels are under a lease, Power Purchase Agreement (PPA), or rent-a-roof scheme, the situation is more complex:

The Problem

The buyer must agree to take over the lease agreement. This means:

• Accepting a 15–25 year financial commitment they didn't choose
• The lease company retains ownership of the panels and equipment
• Some mortgage lenders are reluctant to lend on properties with solar leases
• Conveyancing solicitors may raise concerns

Impact on Sale

Leased panels can:

• Reduce the pool of potential buyers (some won't accept the lease)
• Extend the time to sell (additional legal complexity)
• Reduce the sale price (buyers discount for the lease commitment)
• Cause mortgage issues (some lenders refuse or restrict lending)

Options for Sellers with Leased Panels

1. Transfer the lease: Find a buyer willing to take it on (most common)
2. Buy out the lease: Pay the lease company to terminate early and own the panels outright. Early termination fees can be significant.
3. Remove the panels: Have the lease company remove the system. This may involve costs and leaves you without the generation benefit.

Conveyancing and Legal Considerations

Your solicitor should handle:

Property Information Form

Declare the solar installation in the property information form (TA6). Include:

• Whether panels are owned, leased, or rented
• System size and installation date
• Installer and MCS details
• Any ongoing finance agreements

Building Regulations

Confirm the installation has proper building regulations sign-off (Part P electrical certification). If this is missing, indemnity insurance may be needed.

Planning Permission

Solar panels on most houses don't need planning permission (permitted development). But confirm this — especially in conservation areas or on listed buildings.

Roof Warranties

If panels were installed on a new or recently replaced roof, check whether the roof warranty is affected. Most aren't, but some roof tile manufacturers have specific requirements.

Can You Take Solar Panels with You?

Technically possible but almost never practical:

• Removal costs £1,000–£2,000
• Roof repair costs after removal: £500–£1,500
• Reinstallation at the new property: £2,000–£3,000
• You may need different panels/layout for the new roof
• Total cost: £3,500–£6,500 (close to a new installation)

It's almost always better to leave the panels (which add value to the property) and install a new system at your new home if desired.

Buying a House with Solar

If you're buying a property with existing solar panels:

What to Check

1. Ownership: Are the panels owned outright, leased, or rented? (Critical question)
2. Age and condition: When were they installed? What condition are they in?
3. Warranties: Are panel and inverter warranties still valid?
4. MCS certificate: Does it exist? (Required for SEG registration)
5. Generation data: What has the system actually produced?
6. Inverter age: String inverters last 10–15 years — if it's old, budget for replacement
7. FiT registration: If applicable, is the transfer in progress?

Red Flags

• No MCS certificate (may be a non-certified installation)
• Leased panels with a reluctant or unresponsive lease company
• No generation data or monitoring records
• Visible panel damage or non-functioning inverter
• Missing building regulations sign-off

Green Flags

• Full documentation including MCS certificate
• Owned outright with no lease
• Active FiT registration with good rates
• Recent installation with long remaining warranty
• Well-maintained with generation records

Solar panels on a property you're buying are generally a positive — they reduce bills, improve the EPC, and provide export income. Just make sure the paperwork is in order and the system is genuinely owned, not leased.
