                        "text": "Common mistakes include assuming all rooftop solar is automatically permitted development, checking planning only after the design is finalised, ignoring heritage or conservation constraints, maximising panel count without allowing for safe access, and leaving DNO approval until late in the project. Other issues include failing to check historic planning conditions, Article 4 directions, roof warranties, insurer requirements and whether the roof is near the end of its useful life. Early screening can prevent redesign, delay and avoidable cost."
