Editorial Policy

How Facts Are Checked

Every factual claim on this site is verified against authoritative primary sources before publication. Our reference sources include:

• gov.scot — Scottish Government energy policy, grants and regulation
• Home Energy Scotland — official advice service for Scottish households
• Ofgem — Feed-in Tariff and Smart Export Guarantee rules
• MCS Registry — installer certification and standards (MCS MIS 3002)
• Engineering Recommendation G98/G99 — DNO connection standards (ENA)

Where we quote costs, timescales or regulatory requirements, we link or cite the source. If a figure cannot be independently verified, we state it is based on our own installation data and give the date range.

Review Frequency

All pages are reviewed on a quarterly cycle. Each page displays its last-updated date and next review date. Between scheduled reviews, pages are updated immediately if a regulatory change affects the advice (e.g. DNO process changes, grant scheme updates, tariff rate changes).

• MCS Certified — registration IAA10151
• TrustMark Registered — licence 3559930
• Gas Safe Registered — registration 559575

Technical claims about installation processes, DNO requirements and system specifications are reviewed by qualified MCS-certified solar PV engineers with direct experience of Scottish DNO processes (SPEN and SSEN).

Commercial Transparency

This site is operated by Scottish Energy Efficiency. We sell inverter replacement and solar repair services. Our editorial content exists to inform — but we are not independent journalists. Where our advice leads to a recommendation to replace an inverter, that is a service we provide. We believe honesty about this is better than pretending otherwise.
