Short, practical answers before a sales call.
Costs and support change. We show the date and link to the official source where a rule matters.
How much do solar panels cost?
Energy Saving Trust gives about £6,100 as an average domestic starting point. Roof access, system size, equipment and battery storage can move the price substantially.
Read the source →Warm Homes: Local Grant
Eligible low-income households in privately owned EPC D–G homes may receive local-authority upgrades, potentially including solar. It is not a universal solar grant.
Official guidance →Smart Export Guarantee
Eligible small generators can be paid for exported electricity. Supplier tariffs and conditions differ, which is why our calculator leaves the export rate editable.
Official guidance →Home Energy Scotland funding
Current funding is measure-specific. Ordinary solar PV is not covered by a blanket grant, so use the official funding finder for the property and proposed package.
Check current funding →Energy-efficiency support
Northern Ireland has separate schemes and electricity arrangements. Check current Housing Executive guidance before assuming a Great Britain incentive applies.
