Paying for solar panels without a grant
For most households, the answer to the grant question is no, and the real question is how to pay sensibly. The options are fewer than the adverts suggest, but they are real, and the sums are easier to check than most people think.
The short answer
Yes, there are real options. Pay from savings, or borrow through the Warm Homes Loan Scheme if you own your home. Either way, installed solar is zero-rated for VAT until 31 March 2027, and export payments add income once the panels are running. The value comes mostly from using your own electricity.

Paying for solar is paying for electricity in advance
A solar installation is, in effect, a long advance purchase of electricity. You pay up front, or over the term of a loan, for equipment that then produces electricity for many years. The question to ask isn't "how much grant can I get?" but "how does the cost compare with the electricity it will replace, and the exports it will earn, over its life?"
Seen that way, three things matter much more than any grant headline. The price you pay for the system. How much of its output you will use yourself, which depends on when you use electricity. And what you are paid for what you export. A system sized to your home, bought at a fair price, can do well with no grant at all; an oversized one, or one bought on a misleading promise, can disappoint even with help.
The main options side by side
| Option | What it costs you | Worth knowing |
|---|---|---|
| Savings | The price, plus the interest the money would have earned | No borrowing, no credit check |
| Warm Homes Loan Scheme | The price plus interest, lower than ordinary borrowing per the government | Owner-occupied homes; participating lenders; MCS installer for each measure |
| Other borrowing | The price plus the lender's interest | Compare the total repayable |
| Installer finance | Depends on the product | Ask who the lender is and whether it's part of any scheme |
| Roof rental | Nothing up front; the company keeps the income | A lease on your roof; check its effect on selling or remortgaging |
Self-use first, exports second
Every unit of solar electricity you use as it's generated is a unit you don't buy. Every unit you export earns an export payment under the SEG, at a rate your supplier sets. Because the price of electricity you buy is usually higher than the rate paid for exports, self-use is generally worth more per unit.
That makes your daily pattern the biggest factor after price. A household at home in the day, running a washing machine or an electric vehicle charger while the sun is up, uses more of its own generation. One out all day exports more. A battery can move daytime surplus into the evening, at extra cost.
When you get quotes, ask for any savings estimate to be split into self-use and exports, with the electricity price and export rate used. The Advertising Standards Authority has upheld complaints about savings claims that didn't disclose their basis.
The VAT relief and its end date
Installing solar panels in a home is zero-rated for VAT until 31 March 2027. From 1 April 2027 the rate is 5%. Panels supplied without installation are charged at the standard rate. The relief is applied by the installer on the invoice; there is nothing to claim.
The change is real but modest, and shouldn't rush a decision. If your installation might straddle the date, ask which rate will apply to each payment. More on the relief.
In England, new permitted development rules from 27 August 2026 widen where panels can go without planning permission, including some flats, walls and balconies, plug-in solar and stand-alone panels up to 9 square metres. Check the conditions before relying on them.
How to buy well without a grant
- Get more than one quote, from installers certified by MCS for solar PV, and for battery storage if a battery is included.
- Compare like with like: system size in kWp, panel and inverter make, any battery's usable capacity, scaffolding, and warranties.
- Check the VAT line on each quote.
- Ask how any savings figure was calculated.
- Read the contract for cancellation rights, payment stages and what happens if the installer can't complete.
Be cautious of anyone who leads with a grant, a deadline or a price that expires the same day. Those are signs the conversation isn't about your home.
Rule out the grant routes first
If there is any chance you are eligible for a means-tested scheme, check it before borrowing. In England, Warm Homes: Local Grant is for homes with EPC D to G and household income usually of £36,000 or less, or an eligible postcode or benefit. In Wales, Nest offers packages to low-income owners and private tenants.
If neither applies, the Warm Homes Loan Scheme is the government's loan scheme for owner-occupiers. Check the lender is on the GOV.UK list, compare the total repayable, and make sure the installer is MCS certified for each measure financed.

What a household that can pay should take away
There is no grant waiting for you, and no reason to wait for one. Solar's value rests on a fair price, a system that matches your use, and a realistic view of exports. The VAT relief helps until 31 March 2027. The loan scheme is there if you need to borrow. And the best protection against a poor deal is a few comparable quotes from certified installers, read carefully.
