Sunsave has confirmed that Sunsave Plus contracts signed on or after 15th May 2026 carry partial settlement terms that differ from those on earlier agreements. The company states that households who signed before that date are on the older terms1.
"Please note: if you signed your contract before 15th May 2026, partial resettlements work a little differently."
Sunsave Plus is a solar and battery subscription with no upfront cost, repaid through fixed monthly payments over a 10-year or 20-year term2. The company's representative example is 240 monthly instalments of £69, an 8.6% representative APR, based on a loan of £8,063 at a fixed interest rate of 5.9% per year. Each instalment consists of £57 loan repayment plus £12 monitoring and maintenance fee, with a total amount repayable of £16,560, including £5,734 interest and £2,763 in monitoring and maintenance fees2.
Sunsave says customers can pay off part or all of the remaining credit amount at any time without penalties, and that paying part of the balance allows a choice between keeping the same term and reducing the monthly payment, or keeping the same payment and shortening the term. Up to 98% of the outstanding credit amount can be settled while the Sunsave Guarantee remains in place, provided at least £1 per month is paid towards the credit amount, excluding the monitoring and maintenance fee1.
The company gives two different savings figures for a typical four-bedroom family home. One page states such a home "can save £324 per year on their energy bills with Sunsave Plus, even including their monthly repayments"1. Another states a typical four-bedroom family home "could save £516 every year", with a current energy bill of £104 per month falling to £61 per month including Sunsave Plus, a saving of £43 per month2. The sources do not reconcile these figures.
Eligibility is limited to homeowners in England, Scotland or Wales1. Applications can have up to two applicants; the lead applicant must own the property, at least one applicant must be between 18 and 65 years old, and both must be UK residents2.
Why it matters for households
A solar subscription spreads the cost of panels and a battery across fixed monthly payments rather than an upfront purchase, so the household's exposure to grid electricity prices falls from the day the system is installed1. Sunsave states that customers legally own the system from day one and can choose any export tariff, keeping all export income1.
Partial settlement is the route by which a subscriber reduces the outstanding balance early, either lowering the monthly payment or ending the subscription sooner. Because the terms changed on 15th May 2026, two households on otherwise similar Sunsave Plus contracts may face different mechanics if they try to settle part of the balance. The company has not set out, in these pages, what the difference between the old and new terms is1.
Sunsave also states that electricity bills rose by 5.5% per year on average between 2000 and 2020, and that fixed monthly payments provide protection against energy bill inflation1. Households comparing a subscription with buying a system outright, or with a solar panel loan, would need the total repayable figure rather than the monthly payment alone; the representative example puts the total at £16,560 against a loan of £8,0632. Anyone weighing a subscription against a standard import and export tariff arrangement would need to compare the fixed payment with the value of the electricity generated and exported.
What happens next
No further changes to Sunsave Plus settlement terms have been reported. The company has not published a date by which existing pre-15th May 2026 contracts will move to the new terms, or whether they will1.
