"Heritage" describes a style, not a planning approval. A heritage-style window can suit a period property well, but it isn't automatically acceptable where consent is needed.

What matters to a conservation officer
- Proportion and sightlines
- Glazing bar pattern and profile
- Opening method (sliding sash, casement)
- Frame depth and position in the reveal
- Colour and material
