The key factor that determines how solar panels affect your remortgage is whether you own them outright or whether they are leased or installed under a third-party arrangement such as a rent-a-roof scheme.
If you purchased and own your solar panels, most mainstream lenders will treat your property in the same way as any other. Owned solar panels are generally viewed as a home improvement that can add value to your property.
However, if your solar panels are leased or part of a rent-a-roof agreement, the situation becomes more complex. These arrangements typically involve a charge on the property or a long-term lease agreement, which some lenders view as an encumbrance. The third party retains ownership of the panels and the right to access your roof for maintenance, which can create legal complications.
Some lenders may decline applications where there is a lease or licence agreement in place, while others may accept them subject to certain conditions. The terms of the lease, the remaining duration, and the specific lender's criteria all play a role in the decision.
Understanding the distinction between owned and leased solar panels is crucial when planning a remortgage.
Owned Solar Panels
If you paid for the installation yourself or the panels were included when you bought the property, you typically own them outright. This is the most straightforward scenario for remortgaging. You should have documentation confirming ownership, installation certificates, and any relevant warranty information. Most lenders will not have an issue with owned panels and may even view them positively as an energy efficiency improvement.
Leased or Rent-a-Roof Panels
Under these schemes, a company installs panels on your roof at no cost to you, but retains ownership and the right to the feed-in tariff income. In return, you may receive free or reduced-cost electricity. These arrangements typically come with a lease lasting 20 to 25 years and may include a charge registered against your property.
This type of arrangement can be problematic for remortgaging because some lenders are concerned about the lease terms, the impact on property value, and potential complications if the solar panel company ceases trading. A specialist broker may be able to help you identify lenders who are comfortable with these arrangements.
Power Purchase Agreements (PPAs)
A PPA is similar to a lease but involves an agreement to purchase the electricity generated at a set rate. These can also affect your remortgage options depending on the specific terms and the lender's criteria.
When you apply to remortgage a property with solar panels, lenders will typically want to see certain documentation and will assess several factors.
Documentation requirements may include:
- Proof of ownership or a copy of the lease/licence agreement
- MCS (Microgeneration Certification Scheme) certificate for the installation
- Building regulations compliance certificates
- Electrical safety certificates
- Details of any feed-in tariff or Smart Export Guarantee registration
- Roof structural survey if requested by the lender
Factors lenders consider:
- Whether the panels are owned or leased
- The terms and duration of any lease agreement
- Whether there is a charge on the property
- The condition and age of the panels
- Whether the installation meets current building regulations
- The impact on property value according to their valuer
It is worth gathering all relevant documentation before you begin the remortgage process. Missing paperwork can cause delays or even lead to a declined application.
