A new salary sacrifice scheme for residential solar, battery storage and EV charge points has launched to slash household energy bills while cutting National Insurance costs for businesses.

The scheme, run by tech platform Heva Energy and billed as a UK-first, allows employees to fund clean energy systems through pre-tax salary reductions, as with electric vehicle salary sacrifice schemes.

Founders say the scheme could halve household bills while bringing benefits such as no upfront cost, no credit check and net costs as low as £75 a month.

Under the scheme, employees access solar panels, home batteries or EV charge points through their employer. Payments are deducted from gross salary before income tax and National Insurance are calculated.

As an example, a 40% taxpayer saves 42% on the cost of the scheme compared with buying the same system outright or on consumer finance at 12% APR.

The scheme is cashflow positive from day one. For an employee on £60,000 with a company EV and a detached house, the full solar, battery and charge point package costs £123 a month net after tax savings, while generating £171 a month in energy savings.

For an employee without a company EV, a battery-only option is available to all. The battery stores cheap off-peak electricity and releases it during expensive peak hours, effectively halving the average energy bill.

The scheme is designed so employers incur no financial risk. Heva says companies save £2,500 in National Insurance Contributions per participating employee per year and reduce their Scope 3 emissions by 1.3 tonnes per employee annually.

The scheme takes two months from employer onboarding to first installation; and Heva says the NHS and The National Lottery Community Fund are already participating employers.

Ian Napier, co-founder at Heva Energy, said: “Energy price disruption is not short-term. It is a structural shift, and most households have no mechanism to protect themselves from it. Consumer finance for solar locks you into credit checks and 12% interest rates, while salary sacrifice removes both barriers and offers the deepest savings for those who need them most. This is about transforming energy independence from a luxury to a workplace benefit accessible to every taxpayer.”

The scheme uses Tesla Powerwall and EcoFlow hardware, selected for longevity and manufacturer warranty coverage. All installers are vetted by Heva and 21-day repair or replace SLA is included as standard.

Demand for the scheme has tripled in the past month. Customers include sustainability leaders, HR teams and employees looking for a hedge against energy price volatility.

Ian Napier continued: “People are looking at their bills and deciding they want a way out.”

Zobair Mehmood from The National Lottery Community Fund said the scheme is helping its employees deal with volatile home energy prices.

“We already use salary sacrifice for electric vehicles; extending that mechanism to solar and batteries was the most direct way to protect our people from rising bills while making real progress on our net zero commitments. The fact that there’s a battery-only option for employees who can’t participate in salary sacrifice matters to us because we really wanted a benefit our whole workforce could use.”
