Editorial approach
Marcus T. Ellingford writes for readers who need useful questions and a sensible budgeting framework before speaking with vendors, engineers, installers or regulators. Articles distinguish between early estimates and decisions that require professional responsibility.
Review priorities
- Clear separation between equipment, installation and recurring costs.
- Visible assumptions in every calculator.
- Country and jurisdiction caveats where rules differ.
- Links to official guidance for privacy, safety and compliance topics.
