Salary Sacrifice Solar Panels: How the Scheme Works (2026)
You can lease an electric car or buy a bike through salary sacrifice and save tax. Can you do the same with solar panels? Since May 2026, at least one UK provider says yes. But there’s no government-backed solar scheme, and HMRC’s rules treat solar very differently from EVs and bikes. This guide explains how salary sacrifice solar works, what the tax position really is, the questions to ask before you sign, and how it compares with simply buying the panels.
Compare any scheme with a straight cash price
We match you with one vetted, MCS-certified installer who surveys your roof and gives you a fixed, itemised price to own the system outright. It’s the benchmark every salary sacrifice or finance offer should beat. It’s free, with no obligation.

What is salary sacrifice for solar panels?
In a salary sacrifice arrangement, you agree to a lower gross salary and your employer provides a benefit instead. With solar, that usually works like this:
- Your employer signs up with a scheme provider. It has to be offered through your workplace, so you can’t join on your own.
- The provider installs solar panels, a battery or both at your home, with no upfront cost.
- You pay a fixed monthly amount, taken from your gross pay, for a set term. The system is typically leased, not owned by you, during that time.
- At the end of the term, you can usually buy the system or keep using it for a small fee.
The appeal is no deposit, no consumer credit check and, potentially, a lower net cost because of tax and National Insurance. That last point is where it gets complicated.
The tax rules: why solar isn’t like an EV or a bike
Since April 2017, HMRC’s optional remuneration arrangement rules have removed the tax advantage from most salary sacrifice benefits. Only a short list still gets the full benefit:
| Benefit via salary sacrifice | Tax treatment in 2026/27 |
|---|---|
| Pension contributions | No income tax or National Insurance on the amount sacrificed |
| Cycle to Work bikes and safety equipment | Exempt |
| Ultra-low emission cars (electric cars) | Taxed only on a low benefit-in-kind rate, 4% for electric cars in 2026/27 |
| Certain employer childcare | Exempt, mostly for existing members |
| Everything else, including solar panels and batteries | Income tax on the greater of the benefit’s value or the salary you gave up |
In plain terms, for a benefit that isn’t on the list, you normally still pay income tax as if you’d received the salary. What’s usually left is a saving on employee National Insurance, because benefits in kind attract employer’s National Insurance, not employee’s. There is no government-backed “solar salary sacrifice scheme” equivalent to Cycle to Work. Industry groups have asked for one, but as of October 2026 it hasn’t been introduced.
How much could you save?
It depends entirely on how the scheme is treated for tax. Here’s what a £100 a month gross deduction would really cost you in each case, using 2026/27 rates for England, Wales and Northern Ireland:
| Your tax band | If only employee NI is saved (the usual rule) | If it were fully free of tax and NI |
|---|---|---|
| Basic rate (20% tax, 8% NI) | £92 net (8% saving) | £72 net (28% saving) |
| Higher rate (40% tax, 2% NI) | £98 net (2% saving) | £58 net (42% saving) |
That gap is why the question “how is this reported to HMRC?” matters so much. A 42% saving and a 2% saving are very different deals. Scottish income tax bands differ, so the figures change slightly there.
Know your cash price before you compare schemes
A vetted local installer will give you a fixed price to own the same size of system outright, with 0% VAT. Put it next to the scheme’s total cost over the full term.

In May 2026, Heva Energy launched what it describes as the UK’s first salary sacrifice scheme for home solar, batteries and EV charge points. From its launch announcements:
- How it works: employees get the equipment through their employer with no upfront cost and no consumer credit check. Payments are deducted from gross salary.
- The claimed saving: Heva says a 40% taxpayer saves 42% on the cost compared with buying the same system outright or on consumer finance at 12% APR.
- Its examples: an employee on £60,000 with solar and a 20kWh battery pays £123 a month net and saves about £171 a month on energy. A basic-rate taxpayer on £35,000 in rented accommodation can take a 10kWh battery for £75 a month net.
- Kit and cover: Tesla Powerwall and EcoFlow hardware, with a 21-day repair-or-replace commitment.
- It’s a lease: at the end of the term you can buy the system at fair market value or carry on for a nominal monthly fee.
- Changing jobs: payments pause automatically if you go on parental leave or change employer, and the lease includes early termination protection.
- For employers: Heva says they save around £2,500 a year in National Insurance per participating employee, and that it takes about two months from an employer signing up to the first installation.
The launch coverage doesn’t explain how the scheme is treated under HMRC’s optional remuneration rules, or set out the lease term and total cost. Those are the details to get in writing. We have no connection with Heva Energy and haven’t tested the scheme.
Questions to ask before you sign
- How is the benefit reported to HMRC? Will it appear on a P11D or be taxed through payroll as a benefit in kind? What is my net monthly cost after any tax on the benefit?
- What is the term, and the total I’ll pay? Compare that with a cash price for the same system.
- Who owns the system? If it’s leased, what will “fair market value” be at the end, and who decides?
- What if I leave, am made redundant, or my employer stops the scheme? “Payments pause” isn’t the same as “payments stop”. Who do I pay then, and from net pay?
- What if I sell the house? Can the lease transfer to a buyer, or must I settle it? Leased systems can complicate a sale (moving house with solar panels).
- Who gets the export payments and the MCS certificate? Who is the installer, and what is the workmanship guarantee?
- Is the equipment right for my home? A scheme with a fixed menu of hardware may not match what a survey of your roof would recommend.
Other things salary sacrifice affects
Lowering your contractual salary has knock-on effects that apply to any salary sacrifice, not only solar:
- Pension contributions and life cover based on your salary may fall, unless your employer uses a “reference salary”.
- Mortgage applications: lenders may look at your lower post-sacrifice pay.
- Statutory pay, such as maternity or sick pay, can be based on the reduced figure.
- Minimum wage: salary sacrifice can’t take your cash pay below the National Minimum Wage, so lower earners may not be eligible.
Salary sacrifice vs buying outright vs finance
| Route | Upfront cost | Who owns the system | Tax advantage | Watch out for |
|---|---|---|---|---|
| Buy outright | £5,500–£7,500 for 4kW | You, from day one | 0% VAT until 31 March 2027 | Needs the cash |
| 0% installer finance | Often a deposit | You | 0% VAT | Short terms and inflated prices (solar finance) |
| Bank or green loan | None | You | 0% VAT | Interest over the term |
| Salary sacrifice lease | None | The provider, until you buy it | Depends on HMRC treatment, usually NI only | Tied to your employer, total cost, end-of-term price |
| Subscription or roof lease | None | The provider | None | Long contracts and resale issues |
Owning the system outright nearly always gives the best lifetime return, because every pound of saving and export income is yours for 25–30 years. A 4kW system typically saves £730–£800 a year and pays back in about eight to nine years. See solar panel cost UK, are solar panels worth it and 4kW solar with battery.
If your employer doesn’t offer it
Most don’t yet. You can ask your HR or benefits team to look at it, but you don’t need a workplace scheme to get solar tax-efficiently:
- 0% VAT already applies to installed home solar and batteries until 31 March 2027 (VAT on solar panels).
- Smart Export Guarantee payments to households are paid on top of your bill savings (SEG tariffs compared).
- Lower-income households may qualify for fully funded panels (free solar panels, solar grants UK).
- Company directors sometimes ask about putting panels through their own business. Panels on business premises are treated very differently from panels on your home, so take advice (commercial solar).

Salary sacrifice for solar panels now exists in the UK, but it isn’t a government scheme and it doesn’t have the built-in tax break that pensions, bikes and electric cars enjoy. Under HMRC’s usual rules, the saving on a solar benefit is limited to employee National Insurance, so treat any claim of a 40%-plus saving with care and ask exactly how it’s reported to HMRC. A workplace scheme can still suit someone with no savings who wants no upfront cost and no credit check. But it’s a lease tied to your job, and the system isn’t yours until you buy it. Get the term, total cost and end-of-term price in writing, then compare it with a cash price. This is general information, not tax advice, so check your own position with your employer’s payroll team or an accountant.

Salary sacrifice solar panels: frequently asked questions
Can you get solar panels through salary sacrifice in the UK?
Yes, but only if your employer offers a scheme. In May 2026 Heva Energy launched what it calls the UK’s first salary sacrifice scheme for solar panels, batteries and EV charge points, leased through your employer with payments taken from gross salary. There’s no government-backed solar scheme like Cycle to Work, and most employers don’t offer one yet.
Is there a government salary sacrifice scheme for solar panels?
No. The law gives full salary sacrifice tax advantages to pensions, Cycle to Work bikes, ultra-low emission cars and certain childcare. Solar panels and batteries aren’t on that list. Industry groups have called for a solar scheme, but as of October 2026 the government hasn’t introduced one.
How much tax do you save with salary sacrifice solar panels?
Under HMRC’s optional remuneration rules, a benefit that isn’t on the exempt list is normally taxed on the salary you gave up, so the saving is usually employee National Insurance only: 8% for basic-rate taxpayers and 2% for higher-rate. Heva Energy says a higher-rate taxpayer saves 42% compared with buying outright or on 12% APR finance, so ask any provider exactly how the benefit is reported to HMRC and what your net cost is.
What happens to salary sacrifice solar panels if I leave my job?
It depends on the scheme. Heva Energy says payments pause automatically if you change employer or go on parental leave and that its lease includes early termination protection. Ask what happens next: whether you continue paying from net pay, whether a new employer can take the scheme on, and what it costs to buy the system or have it removed.
Do you own the solar panels in a salary sacrifice scheme?
Usually not during the term. The system is leased, and at the end you can typically buy it at fair market value or keep using it for a small monthly fee. That matters if you sell your home, because a leased system can complicate the sale. Buying outright means you own the panels from day one.
Is salary sacrifice better than buying solar panels outright?
Usually not, if you have the cash. Owning the system outright gives the best lifetime return, because all the savings and export income are yours for 25–30 years, and installed solar is already 0% VAT until 31 March 2027. Salary sacrifice suits people who want no upfront cost and no credit check, but compare the scheme’s total cost over the full term with a cash price first.
