Equity Release to Fund Solar Panels UK: Is It Worth It?

If you're retired or approaching retirement, own your home outright (or nearly so), and want solar panels or a battery but don't want to touch your savings, equity release can look like an obvious answer: unlock cash from the house, pay for the install, no monthly repayments. It can work. It's also one of the more expensive ways to finance a solar system, and it comes with trade-offs a standard solar loan or green mortgage doesn't carry. Here's what actually happens if you use it to pay for solar.

What equity release actually is

Equity release covers two regulated product types. The overwhelming majority of the UK market — and the one you'll almost always be offered — is a lifetime mortgage: you borrow against your home's value, keep full ownership, and the interest normally rolls up rather than being paid monthly. The loan plus accumulated interest is repaid when you die or move permanently into long-term care, usually from the sale of the property. The far rarer alternative is a home reversion plan, where you sell all or part of your home to a provider below market value in exchange for a lump sum and the right to live there rent-free for life.

Both are FCA-regulated products. Advising on or arranging equity release is a regulated activity, and the Financial Conduct Authority requires firms to follow specific advice and disclosure standards under its mortgage conduct rules.

What it costs compared with a loan

Equity release interest rates are typically higher than a standard residential mortgage, and they vary significantly between providers and plans. MoneyHelper — the government-backed guidance service — doesn't publish a live rate table and instead recommends shopping around with a qualified, FCA-regulated equity release adviser to compare current offers. Because interest usually compounds (rolls up) for as long as the loan runs, the amount owed can grow substantially over 10–20 years even at a fixed rate, which is a very different shape of cost to a fixed-term personal loan you pay off in five or ten years.

For a typical residential system, it's worth checking what solar panels actually cost in the UK first — for a modest installation, the sums borrowed on equity release (which usually has a minimum loan size and setup costs) may not stack up well against a smaller, shorter-term loan or simply paying from savings.

Safeguards if you go ahead

Most UK equity release lenders are members of the Equity Release Council, whose product standards apply regardless of which provider you use, including:

• A no negative equity guarantee — you or your estate will never owe more than the property is worth (after reasonable sale costs), as long as the terms are met.
• The right to remain in your home for life, or until you move permanently into long-term care.
• Portability — the right to move to another suitable property, subject to the lender's criteria at the time.
• A fixed or capped-for-life interest rate on lifetime mortgages.
• A requirement for independent legal advice from your own solicitor before you complete, on top of regulated financial advice beforehand.

The FCA has previously flagged poor advice and misleading promotions in parts of the later-life lending market, which is exactly why using an Equity Release Council member and taking independent advice — rather than going direct through a solar installer's in-house finance partner — matters here more than with most home improvement finance.

Could it affect your benefits?

This is the part homeowners most often miss. Money released from your home counts as capital once it's sitting in your bank account (spending it on the actual solar installation removes it from that calculation, but any unspent balance counts). For Pension Credit, the first £10,000 of savings and capital is disregarded, and every £500 (or part) above that is treated as £1 a week of deemed income — which can reduce or remove your Pension Credit entitlement while the cash sits unspent. Universal Credit claimants below State Pension age are affected more sharply: capital under £6,000 is ignored, £6,000–£16,000 is tapered as income, and £16,000 or more usually ends eligibility altogether. Council Tax Reduction is run by your local council rather than a single national scheme, but for pension-age claimants it generally mirrors the Pension Credit capital rules — check your own council's scheme before you release a large lump sum.

The practical fix, if this applies to you, is to draw the funds close to when you need to pay the installer rather than releasing a large sum and letting it sit in an account across a benefits assessment.

What it means for your estate

Because a lifetime mortgage is normally repaid — capital plus rolled-up interest — from the sale of your home when you die or move into care, it directly reduces what's left for your beneficiaries. A home reversion plan has the same effect in a different form: the provider owns the share you sold, so your estate only inherits what's left. If leaving the house (or its full value) to family matters to you, this is the trade-off that needs weighing against the value of having solar panels and lower bills now.

VAT relief and the Smart Export Guarantee still apply

Good news on the practical side: how you pay for the installation doesn't change the tax or export treatment. The 0% VAT relief on qualifying solar panel and battery installations (materials and labour) runs until 31 March 2027, after which it reverts to the reduced 5% rate — see our full VAT and grants guide for the detail. VAT liability is determined by what's being installed and where, not by how the customer paid for it, so equity release funding doesn't change your VAT position. The same goes for the Smart Export Guarantee: eligibility depends on having an MCS-certified installation, a compliant export meter, and a tariff from a licensed supplier — Ofgem's criteria don't reference how the system was financed.

Is it worth it?

MoneyHelper's general guidance on equity release for home improvements is blunt: it can be an expensive way to raise a relatively modest sum, and it's worth ruling out cheaper alternatives first — a shorter-term loan, using existing savings, a retirement interest-only mortgage, or simply downsizing, before signing up to a product that compounds interest over what could be a 20-year-plus horizon. Equity release can make sense if you're already planning to use it for other purposes (care costs, gifting, general retirement income) and solar is one line item within that decision. It's a much harder case to justify if solar panels are the only reason you're considering releasing equity from your home at all.
