Solar Panels on Finance: Spread the Cost, Maximise Your Savings

How solar panel loans and monthly payments work

Once approved, your lender or installer covers the upfront solar panel cost, and you repay through fixed monthly payments.

Most solar finance options in the UK are offered at a fixed APR over an agreed term. iHeat currently offers solar panel finance at 9.9% APR, allowing homeowners to spread the cost over several years rather than paying the full amount upfront.

This flexibility helps match the repayment plan to your budget.

Example:
For a typical 4kW solar system costing around £6,000, repayments could be spread over several years at 9.9% APR, reducing the upfront financial impact while allowing you to benefit from solar immediately.

For larger systems, finance can extend over longer terms to keep monthly instalments manageable.

Common types of solar financing in the UK

Homeowners in the UK typically finance solar panels in three ways:

Installer finance - Offered directly through companies such as iHeat at 9.9% APR, subject to status and affordability.

Personal loans - Taken out through a bank or building society at their advertised rates.

Government incentives – Including VAT relief and funding support through schemes such as the Boiler Upgrade Scheme where applicable.
