The short answer

Do you need planning permission for a loft conversion in Worcester?

Rear dormers and roof enlargements are normally permitted development under Class B, within volume limits, but Class B rights do not apply on article 2(3) land, which includes every conservation area. In Worcester this matters: the borough has 18 conservation areas, and inside those the permitted development route narrows or is removed, so a loft conversion can need a full application where it would not two streets away.
