Solar for 1 million UK homes. No upfront cost.

The Household Energy Independence Programme installs solar panels, battery storage, and EV chargers on your home, funded by green bonds. You save from day one. It costs the Treasury nothing.

The Golden Rule

The levy is always below the saving.

A typical household installs a kit worth around £5,300, saves £700 per year on electricity, and pays a levy of £415 per year. Net benefit: £285 per year from day one. After 15 years the system is paid off and the full saving is yours.

How it works

Bonds issued in tranches of 100,000 homes, each independently self-repaying. Unit economics are identical at any volume above the pathfinder.

1

Pathfinder

10,000 homes across two sites (Reading and Leeds). Budget: £50 to £65 million. Validates the delivery model, the levy mechanism, and consumer satisfaction before national rollout.

2

Phase 1: Scale

1 million owner-occupied homes. Green bonds issued in tranches of 100,000 homes. NWF anchors the first tranche; pension funds and securitisation vehicles fund at scale. Each tranche is independently self-repaying.

3

Phase 2: Extend

3 million homes, extending to social housing, rental properties, and flats. The model adapts for different tenure types while preserving the golden rule: the levy is always below the saving.

Your home energy system

Every home receives solar panels, battery storage, a hybrid inverter, and an EV charger. You own the equipment from the moment it is installed.

Component What it does
Solar panels (4+ kWp) Generate electricity from daylight. Even on cloudy days, you produce power that reduces what you buy from the grid.
Battery (5–10 kWh) Stores excess solar energy for the evening. Use your own electricity after dark instead of buying from the grid at peak rates.
Hybrid inverter Manages the flow between panels, battery, grid, and your home. Fully automatic.
EV charger (7 kW) Charge an electric vehicle at home using your own solar power. Ready when you need it.
Kit Solar Array Battery Target Home
Starter 4.2 kWp 5 kWh Flats and terraces
Family 5.9 kWp 10 kWh Semi-detached homes
Large 10.1 kWp 15 kWh Detached homes
Industrial 12.6 kWp 20 kWh Large properties and community buildings

10,000-home pathfinder

Before national bond issuance, a pathfinder proves the delivery model, the levy mechanism, and consumer outcomes. Phase 1 proceeds only if the pathfinder meets all four success thresholds.

Site 1

Whitley, Reading

5,000 homes. Most deprived ward in Berkshire, 35% social housing, approximately 30,600 owner-occupied homes eligible in the constituency. Local authority partnership and door-to-door recruitment.

Site 2

Inner Leeds

5,000 homes. Burmantofts, Richmond Hill, Gipton, and Harehills: 25% fuel poverty. Approximately 29,000 owner-occupied homes eligible. Housing association referral pathway.

Budget

£50 to £65 million

Kit 2 (5.9 kWp solar, 10 kWh battery, hybrid inverter, 7 kW EV charger) installed at pathfinder volumes: £5,000 to £6,500 per home. 18 months from procurement to evaluation.

Success Criteria

Four thresholds

Savings reach 90%+ of projections. Levy default rate below 3%. Consumer satisfaction above 80%. Ofgem regulatory clearance for the meter-attached levy mechanism.

What this is not

This programme is structurally different from previous energy schemes.

Not a subsidy

Self-repaying through the levy. Zero Treasury cost beyond the pathfinder.

Not the Green Deal

Different rate (4–4.5% vs 7–9%), different scale (1 million homes vs 1,754), different mechanism (infrastructure deployed, not a loan applied for).

Not a nationalisation

Households own the equipment from day one. It is fixed to your property and belongs to you.

Not a tax

A levy on participating households only, always below their saving. Non-participants are unaffected.

Why now

Multiple pressures are converging to make this programme both urgent and achievable.

£37 billion energy trade deficit

The UK imports more energy than almost any comparable economy. Every rooftop solar system reduces that dependence.

North Sea in decline

Oil and gas production has declined 77% since 1999. An estimated 90% of recoverable reserves have been extracted.

Future Homes Standard (2028)

New builds will require solar as standard. This programme brings the same technology to existing homes.

Government alignment

Warm Homes Plan (£13.2bn), GB Energy (£8.3bn), Green Prosperity Plan (£23.7bn), and the Green Gilt Programme (£51bn+) all support this direction.

Rising energy costs

Ofgem price cap at £1,641 per year from April 2026. The Iran conflict continues to drive wholesale prices higher.

Plug-in solar deregulation

The government is actively deregulating small-scale solar installation, reducing barriers to deployment at scale.

“This transition is happening whether we lead it or not. The question is whether British families own their energy, or keep writing cheques to regimes we cannot control.”
