When to use this service
Start with the decision that needs to be made. For an existing home with high energy use or comfort problems, define the objective and verification criteria before selecting equipment or materials.
Inputs
Provide measured drawings, condition, bills and occupancy patterns. Missing information is recorded as an open question so assumptions do not silently become design facts.
Scope and deliverables
Deliverables: a sequence of measures with coordinated risk checks. The drawings, calculations and consultations are agreed in the brief. Options are compared using consistent starting assumptions.
Stages
Brief → input review → option analysis → agreement → delivery. Each stage records decisions and questions that affect the next.
Scope boundaries
Surveys, specialist investigations, approvals and independent certification are included only where explicitly agreed. Cost and timing depend on scope and input completeness.
