Is there a government grant for solar?

No general grant for most homeowners. Available: 0% VAT (everyone), SEG income (everyone), ECO4 (low-income only), BUS grant (heat pump combo). These are sufficient for strong ROI.

Can I get free solar panels?

Only through ECO4 (low-income, means-tested benefits, EPC D-G property). For most homeowners: no. Beware 'free solar' adverts — usually leases or scams.
