Editorial policy

Every figure, grant amount, and cost range published on this site is checked against primary sources before publication and reviewed on a regular schedule. We do not invent facts, round numbers for convenience, or present estimates as confirmed.

How does Solar Battery Upgrade Scotland check facts?

Every figure is verified against primary sources — HES for grants, HMRC for VAT, supplier pages for tariffs, and real installer quotations for costs.

Grant figures are verified against Home Energy Scotland published rates and terms. Each figure carries a “checked” date.
VAT rates are confirmed with HMRC guidance on energy-saving materials.
Export tariff rates are sourced from supplier tariff pages. We never guarantee a rate and always state the date checked.
System cost ranges are based on real quotations from our installer partner, Home Heating Services (Scotland) Ltd (SC484353), an MCS-certified installer.
Solar yield estimates use gov.scot and MCS MIS 3002 methodology for Scottish irradiance zones.

How often are figures reviewed?

Grant figures, export rates, and scheme status are reviewed at least quarterly. Cost ranges update when supplier pricing changes.
